New Central Heating – A Home Investment

Installing a new central heating system could be one of the best investments you make. Modern systems are very efficient, generating more heat for less energy. This could reduce your bills dramatically and also help the environment.

Why should I upgrade my central heating?

There are a number of situations when you should consider upgrading. The most common is if your home has an old electric storage system. Switching to a new gas-powered system is very wise. The upgrade can be a long term investment, providing more reliable heating, new features, and lower bills over time.

A second reason to upgrade is if you have any concerns about aspects of the current central heating system. If you are making changes to the boiler, radiators, or heating controls, it may be better to choose a completely new system. That way you can ensure it is modern and in the best condition. A new central heating installation can have less risk than replacing individual parts too.

What should I consider when opting for central heating installation?

If you do opt for a new boiler installation with your New Central Heating there are a number of important things to think about. The first is what kind of boiler you want. There are plenty of options, from different styles to various types of fuel. The choice will depend on a number of things including the size of the property and the amount of space that is available. You’ll also want to think about what manufacturer to opt for.

The next vital thing to consider is the style and size of the radiators. Again there is a lot of choice. You can choose modern or traditional designs, various materials, and different colours and finishes. On top of these you need to look at heat output and efficiency.

The final thing to check is how easy the new system will be to install. The costs will increase steadily according to the difficulty. If the property is large and currently occupied, it will take longer to complete the job. This has an impact on how much you need to pay for labour. More complex systems also have a larger number of parts, increasing the cost.

Heating Controls

One of the great things about modern central heating is that you can install zoning heating controls. Older systems allow you to either have the boiler on or off, heating the whole home or none of it. With zoning, the property is split up into different areas. You can then control these independently, setting different temperatures to suit you.

With modern heating controls like these you can save a lot of money on your bills. You can also have thermostats installed in each room, allowing the temperature to be set to the right level for the occupant. This means no wasted energy heating an entire property to the same temperature when many rooms are not in use.

Top things to decide before selecting a new boiler

The size

Combi boilers generally come in four sizes; 24-25kw, 28-30kw, 33-35kw, and 40kw. The smallest are ideal for small two or three bedroom homes with anywhere up to ten radiators. With this as a base you can determine which size will be best for you. Keep in mind that every kind of combi boiler will struggle to run two showers simultaneously. Always consider water usage demands.


Not surprisingly it is easier to install a new boiler in the same location as an existing one. This will ensure all the necessary amenities are already in place such as water pipes. If you relocate the appliance you may need to run additional pipes or gas lines. The easiest option is to install the same kind of boiler in the same place. That way installation will be cheaper and take the least amount of time.

Energy Efficiency

Older boilers will have an energy rating from A-G. This is determined by the old SEDBUK classifications. New boilers will now have a percentage rather than a letter. This is the ErP rating and it was introduced in 2015. The law also states that all new boilers should be condensing.

What boiler brand should I choose?

There are a number of different brands to choose from. Generally it is better to stick with the most reputable manufacturers, including Vaillant, Worcester Bosch, Baxi, and Ideal. There are some important things to think about when choosing a specific model, including the length of the warranty. It is always best to do your research to see which brand and model will suit your needs.

Identifying the size of the gas pipe

The pipe should be 22mm thick. You can check it in your manual. Some older models will only have 15mm pipes and could require an upgrade alongside the new boiler. The upgrade is necessary because when a pipe is too small it can affect how well the appliance functions.

System flushing

When you get new central heating it is wise to have the full system flushed. This is prevent existing sludge from damaging your

new boiler. A new filter may be necessary to prevent sludge from building up in the future.

Water pressure

It is vital that the pressure is tested before installing a new appliance. A new combi boiler will require a minimum flow rate to operate properly. If you don’t meet the requirement you may need to choose a different model.

How long will new central heating installation take?

As a rough guide it takes anywhere from 6 to 10 hours to fit a new combi boiler in place of the same kind of model. If you are converting from system to combi it could take 2-3 days because of the size of the job.
