Central Heating

Your central heating system plays a vital role in every home. The two main functions that, central heating fulfils are providing domestic hot water and central heating. Keeping your home supplied with the heat and hot water that make your it so comfortable. The boiler is the most essential part of a central heating system. Your boiler can be pre-programmed only to provide heating at certain times, or wait until the temperature drops below a threshold. Controlling the precise rate of fuel consumes and the temperature of the boiler determines whether or not the boiler burns cleanly and efficiently.

Manufacturer Warranties (maybe add under brands)

Some of the larger manufacturers such as Vaillant, Worcester, and Ideal offer up to 10 or even 12-year boiler warranties. If a manufacturer credited engineer installed the boiler, the manufacturer usually extends the warranty.

How much cover does the boiler warranty give me?

The warranties provided by the manufacturer are generally quite comprehensive. Warranties provide reassurance that the manufacturer will get your boiler back up and running again if a fault develops within the warranty period. Here at CM Plumbing & Heating we understand that boiler warranties are essential to our customers.

Unfortunately, boiler warranties are not very clear as boiler manufacturers have reacted to market conditions. They now offer different warranties on different models. Each manufacturer has developed separate schemes to loyal installers, and retail facing offers on warranties to grab customer attention. No matter what boiler you have, from a combi boiler to a traditional gas boiler, the manufacturer's warranty is an essential element of your central heating system. If your boiler breaks down and you need a repair carried out you should call us on 01273 257 447 to see if the boiler guarantee covers all work we would need to carry out. Occasionally even the best boilers break down, so ensuring you understand the warranty can save you a lot of money.

How do I make sure I make the most of my Warranty?

TThe first thing to do after you have purchased a boiler is to ensure that you register the boiler with the manufacturer. Failing to register is a common issue if there is ever an in warranty claim. If the manufacturer is aware of the details of your boiler installation, getting a service engineer out to fix the issue is much smoother. Even then your plumber needs to register the warranty in the way that meets all of the manufacturer's requirements to achieve the longest available warranty for that model of boiler.

All boilers should be installed by a Gas Safe installer. Having the installation signed off by a gas safe engineer makes your warranty valid and means that if the boiler has a fault in the first year, you are covered. Most warranties are lost if you don't have a regular service done by a gas safe engineer; however, at CM Plumbing & Heating we can arrange a yearly boiler service.

Boilers By Type

Currently, there are several different boiler types and fuels to choose from. The most popular boiler is the combi followed by system boilers & then heat only, which can also be called conventional or regular. The two types of fuel our boilers can take are gas & oil. If your house does not have a gas connection, an oil boiler might be the solution for your heating needs. The high efficiency of oil boilers will save you money compared to other non-gas central heating systems. Although there are also electric boilers to choose from our boiler installation partners are unable to offer electric installation.

Combi Boilers

Combi boilers are the most common type of boiler in the UK, so you have a large range of models to choose from, at every price point. They're called combi boilers because they act as both your water heater and your central heating boiler. One massive benefit of switching from a system or regular boiler to a combi is being able to take back the space taken up by your now redundant hot water cylinder. On the other hand, if you choose to replace a standalone boiler system with a combi boiler, the required labour is typically far more involved.

We think of it in two stages, the work needed to complete the conversion of boiler type, and the labour needed to install your new combi boiler. With advancements is gas engineering, modern combi boilers are close to plug and play. Once the conversion is complete, any further replacement boilers can be installed quickly and simply by CM Plumbing & Heating gas safe engineers. Of course, the best way to find out what it will take to replace or install a combi boiler system is to contact us for more information.

Conventional/Heat Only/Regular Boilers

Using a separate water cylinder and boiler, conventional boilers, also known as heat only, traditional or regular boilers, run your central heating system. It will be cheaper to install a conventional boiler. Conventional boilers tend to be an excellent option, for bigger homes with a much higher demand for warm water, as they require room for a water cylinder to store hot water. Depending on different variables, the cost of a standard boiler can differ significantly. For more information and a quote, please contact us.

Condensing Boilers

Condensing boilers are systems that have mounted within it a Flue Gas Heat Recovery System. The flue filters out the gas and heat that are by-products of all boilers. The Flue Gas Heat Recovery System acts as a condensing unit, meaning that much of the heat that is normally lost is instead fed back into the boiler system. Using a condensing unit makes for a much more efficient central heating system. This added efficiency then, in turn, reduces your costs. Modern A-rated condensing boilers like those in the Greenstar range of Worcester Bosch will be more than 90 efficient, meaning you will get a lot more usable heat per unit of fuel used.

System Boilers

If you know you'll get through a lot of baths and showers each day, with multiple hot water demands, you might be better suited by system boiler. System boilers take their water directly from the mains supply then heats your central heating system and also produces hot water for a storage cylinder. In this way system boilers sit in the middle between a combi boiler and a conventional boiler. Due to its added internal components, you don't require a hot water tank with a system boiler, although you do still need a hot water cylinder.

With no hot water tank system boilers can be much easier to install than conventional boilers, and they usually take up less space. System boilers use a cylinder which makes them more suitable for larger homes with more than one bathroom.

Heat Interface Units (HIU)

The installation of Heat Interface Units (HIU) happens during the construction of large apartments and social housing projects. It is a boiler look-alike box that transfers heat from the network heating system into each of the central heating systems of every home. HIU acts as a connection between the main central boiler and the heating systems of each property. HIU's allow heat to be accessible instantly, at whatever point it is required by simply setting the thermostat and heating programmer.

Boiler Parts

At CM Plumbing & Heating, we have boiler spares and parts in stock from all major names in plumbing and heating. It's never been easier to get the components needed to carry out repairs. If your appliance has yet to be listed or has no associated spares, ring us on 01273 257 447 with the boiler make and model or GC number to hand, and we will be glad to help.

The Cost of A New Boiler

The price of a boiler varies massively depending upon your choice of brand and model. Finding the best possible deal on a given boiler can be time-consuming, so we're here to help take the pressure off. Buying a new boiler can save you money, but it's important that you get a great boiler and a great deal.

If you've got a boiler in mind and want to purchase it yourself (and then find an installer to fit it), you can opt for supply only which we also cover in more detail below. With so many variables affecting the cost of a new boiler, it's important that you seek expert help and advice before getting a quotation. It's good to remember that not all boilers are suitable for every situation. For example, a 24kW boiler will produce enough energy for a couple living in a one-bedroom property with just one bathroom, but it won't be sufficient for a four-bedroom house with two occupants and two bathrooms. At CM Plumbing & Heating, we have years of experience supplying and installing boilers; our experts will be able to give you a good idea of the cost required to get the boiler you need.

Boiler Installation

Getting the right boiler installation for your home will depend on several factors such as the size of the property, number of rooms, energy source, and more. A gas safe engineer from CM Plumbing & Heating will look at your existing central heating system and ask a few questions to understand your heating and water requirements and whether that's likely to change in the future. After reviewing our available products and your heating needs, CM Plumbing & Heating will provide you with a no-obligation fixed price quote within 24 hours.

Plumbing and Heating Services in Brighton and Sussex

For each installation we have to consider a range of practical factors such as size or dimensions, radiator replacements, flue length, and position removal of old water tanks – so if you are replacing an old traditional boiler with all of the above, installation is likely to take 2-3 days. If your gas run isn't up to standard, it may need an upgrade, and this could take additional time. After your new boiler installation, you will start saving money on your energy bills and maintenance costs should be very affordable. The money you could save in the long run could go a long way to paying for your new boiler.

Boilers Installation Costs

The boiler and installation costs are usually quite clear, but in some circumstances, customers might have to pay for extras such as additional pipework, radiators, etc. Additional costs for these are likely to be marginal in comparison to the cost of installing a new boiler. The energy-saving your new boiler provides should easily pay for the additional cost over the lifetime of the boiler. Our installation cost already includes a smart wireless programmable roomstat which when combined with a high-efficiency boiler like the Viessmann Vitodens range will comfortably take you over the efficiency required for Boiler Plus Legislation 2018.

New Boiler or Boiler Cover for an old boiler?

Boiler cover will grant you access to engineers who, in an emergency, can repair your heating. The first thing to ask yourself is about the age of your boiler. Once your boiler passes a certain age getting insurance doesn't make sense. Any policy you do get is unlikely to be cost-effective, and you might not even get cover at all.

Most who opt for cover will never have to claim, and so they end up spending more on the boiler cover than getting a brand NEW boiler fitted would cost, and a new one means the new warranty or guarantee will automatically cover you.

Signs That Your Boiler May Need Repairing

Boiler Leaks

If you notice water coming from your boiler, you will first need to work out exactly where the liquid is coming from. The most likely cause is a faulty component, often the pump seal, which needs a repair or replacement. However, if it is inside the boiler, there's a chance the water could cause expensive electrical parts to break. A poor boiler fitting or corrosion are other possible reasons.

Warning lights

This warning lights indicate there is likely an issue with the valve. When heat is needed, the valve opens to provide more fuel. When a boiler's gas valve is incorrectly adjusted, when supplied with too much gas, or too little gas, it will lock out.

Boiler sounds

If your boiler fails to ignite and you can't hear the fan, this is another potential issue.

Water pressure

For your boiler to work as efficiently as possible, the pressure of your water needs to remain at a constant level. If the pressure levels become too high or too low, your boiler could fail. Just by taking a look at the gauge, you can see if the pressure is too low or too high to control the flow of water around the heating system effectively.

By bleeding your radiators, you can help to reduce the pressure until the pressure gauge indicates the pressure is within the norm. If your boiler pressure is too high and bleeding your radiators doesn't fix the issue, call on one of our engineers 01273 257 447.

Boiler Repair in Brighton

You may at times feel as though your boiler has a mind of its own, especially if it repeatedly switches itself off. The causes can vary hugely, and often range from deposit and air build-up to an issue with pressure or individual components. A wiring issue could stop your boiler not turning off. We, therefore, recommend you contact a Gas Safe engineer to deal with the issue. During your repair, your engineer may remove power from your boiler and examine its wiring. They may also check the shut-off controls, paying attention to the low-temperature switch as this is made to keep the boiler running if it thinks the water inside isn't heated sufficiently. If your boiler includes a manufacturer-backed warranty, it's usually best for you to contact them first when you encounter a problem so that they can try to resolve the issue. Contact us today, and our friendly advisors could organise for your boiler to be repaired by our trained engineers at a time that suits you.

Common Boiler Problems

Boiler problems can be frustrating, dangerous and costly – but they aren't always obvious. Do your radiators struggle to warm or take hours to get hot? These symptoms could mean that your boiler is on its way out. A healthy boiler will never release any odour. If it does, then it needs to be investigated right away. If your bills are going up faster than normal, it's likely due to an inefficient boiler. As a heating system ages, it can lose its efficiency and start to cost more to run. If puddles start to appear around your boiler, you should take immediate action. Internal parts may be faulty or have started to disintegrate. A boiler with a leak will usually result in a boiler with low pressure and a boiler that is locking out. If it has been raining, and the rainwater has caused your leak; this indicates incorrect fitting of the flue and water is leaking down the flue into the boiler. Get an engineer for this urgently. Your boiler likely makes a noise when firing up; this should stay a low and constant hum that most of us won't even notice. However, banging, clunking and whirring are the sounds you don't want to be hearing. These could indicate several issues, from a broken valve to heat pump problems. Arrange for our heating engineers to come and fix the problem. If it's a gas boiler, make sure you only work with a Gas Safe registered engineer, or an OFTEC qualified engineer if you have an oil boiler. Do not risk a serious problem or run out of hot water and heating; call CM Plumbing & Heating now on 01273 257 447.

Boiler Servicing: Keep Your Home Warm and Gas Safe

Manufacturers require a boiler service every year to keep the warranty in place. Without this yearly service, you will lose your warranty. All boilers come with a standard one year warranty that can be extended. In most cases, they often come with extended warranties of 2 years to a ten-year warranty. These are all great, but to keep them you have the added cost of the boiler service every year. It's a good idea to keep your service history with the boiler in a safe place and be ready to give the serial number of the boiler as well as service history to the manufacturer if you have a problem. With extended manufacturer warranties, there are often caveats, and reward schemes for loyal installers will offer extended warranties on boilers an additional two years.

Gas Boiler Replacement in Brighton

Although the age of your boiler isn't the main factor in determining whether it's time to replace your boiler, it may be useful to be able to date the installation. In most cases, the manufacturing date of the boiler will be coded and hidden within the serial number. Often if it's an older, discontinued boiler, you can try to find the date when they these boilers stopped being made. The best point of reference is the Building Energy Performance Assessment site. They have a very convenient and large boiler database. If a boiler finished production in 2006, then at least you can assume that your boiler is no younger than nine years. Of course, it's not the most accurate way of telling the age of your boiler, so hopefully, you have one of the main brands. If you come across a more obscure boiler and you struggle telling its age, please get in touch, and we'll see if we can help.

What boiler brands are there to choose from?

If you want to get the most out of your boiler, it's important to get one that fits with your home and lifestyle. Modern boilers have been developed to fit homeowners needs with reasonable specificity, so most brands have boilers that fulfil your heating requirements at various price points. If you are looking for a boiler for your Brighton property, there are plenty of great options to choose from. CM Plumbing & Heating provide compact boilers, perfect for small and medium-sized to larger homes. Our boilers are also perfect for replacing an old boiler in an existing heating system. Although they can be more costly, the more reliable your new boiler brand is, the less you have to shell out on repairs. On the other hand, the main selling point of a budget boiler is the price.

Please book an appointment with one of our expert engineers now. If your boiler is showing a fault contact us to arrange a repair with a Gas Safe registered engineer. Whenever we are asked to help a customer fit or replace their boiler with a new one, we follow a series of stages. One of our experts will take a look at your heating system talk you through your options and give you a fixed price quote.


Our gas safe engineer will come to your house with everything they'll have to complete the work for the boiler installation at the agreed time and date. You'll need to be present at the property to allow access to our engineer. Your engineer will walk you through the extent of the work they'll be doing, so you would know what to expect while work is ongoing and after completion. If it's a straightforward swap, a combi for a combi, you should expect the engineer to finish within the day. However, if it's a much older boiler system or you're changing the boiler type, there may be complications which may prolong the installation process. You might need to be around to have a go through of the new boiler controls once it's fitted.

If you've chosen to have the same type of boiler installed in the same location as your current one, then you're likely to see very little disruption. Changing the type or location of your boiler could be more problematic and take more time to install. For instance, it is quicker to swap a combi boiler with a new combi boiler than it is to swap a system boiler with a combi boiler. However, individuals, for the most part, find that swapping to a more energy-efficient boiler is beneficial in the long run, despite any disturbance that can occur during installation. When you've established your central heating needs and know the type of boiler you want, the subsequent step is to decide on the boiler brand and model.

New gas boilers must be installed by an installer with a Gas Safe certificate, to follow building and safety regulations. A registered installer will assess your home and give advice on which boiler would be ideal for your system. If you and try installing the boiler by yourself, you'll still need a gas safe registered professional to test, accept, and sign it off. However, any reliable engineer will likely be hesitant to sign off a boiler that they have not personally fitted. Without having it signed off, you will lose the warranty.

If there are any problems later on, you'll be held liable, and any repairs will be difficult to come by.

Lastly, you will have problems with the local council and the Health and Safety Executive, making things more complicated. Also, a poorly installed boiler represents a danger to your family and your home. Your best course of action will always be to follow regulations and have a Gas Safe registered engineer install the boiler and carry out required gas works.

Heating Experts Here to Help

Buying a new boiler is expensive and complicated at the best of times - let alone when your old boiler suddenly breaks down. However, fear not, if you're thinking about replacing your boiler help is at hand. Our boiler engineer will be an invaluable source of information during the buying process.

Saving money on bills for years to come

If you are replacing an old boiler with a modern condensing boiler, you should save a decent amount on your energy bill. The correct heating size of your boiler will be something unique to you and your home, as it depends on things such as how many bathrooms you have and how many people you live with.

Getting this right is something your heating engineer can help you with, and he or she will be key to making sure you achieve your hot water and heating requirements.

If your boiler continues to switch itself off then the boiler pressure could be too low, or there could be a blockage in the system restricting water flow, or the pump could be faulty and therefore not circulating the water properly.

  • Your boiler pressure should be indicated on the boiler by a dial.
  • If your boiler has lost pressure, you can quickly resolve this yourself.
  • Please refer to your boiler user manual, or we've got a video available that explains how you can repressurise your heating system should you need to.
  • If your boiler pressure is correct and doesn't need re pressurising then contact us for further help in diagnosing and repairing the problem.

Boiler maintenance starts with you. A heating engineer will keep your boiler in good condition, but there are also many things that you should do yourself.

The first thing to check on your boiler is the pilot light if you can see it. If it is a powerful, blue flame, then your boiler should be in good shape. On the other hand, if the flame is orange or yellow, this is a surefire sign that your boiler isn't completely burning its fuel.

Regularly check the pressure gauge on your boiler. The gauge should constantly point between 1 and 1.5 bar. If it ever falls below, you need to top up the pressure of your boiler.

Every boiler instruction manual should list specific ways to increase the pressure. If the pressure doesn't improve, or the manual is lacking, your heating engineer or plumber will be able to assist you.

Your boiler must have enough ventilation in order to run safely.

To avoid your pipes freezing, you can install lagging on them. Lagging is a type of insulation for pipes, often made of mineral or glass wool, foam, or polyethene.

Make sure that your home has excellent insulation and fill in any gaps and holes that lead to the outside.

Finally, you should get your heating system, and the boiler checked at least once a year.

A certified engineer will conduct a complete boiler maintenance check. They'll confirm that all components are operating properly, clean your system, and repair or replace whatever is necessary.
