Boiler upgrade or replacement
Replacing an old or inefficient boiler could save up to £405 every year1 on energy bills. But a boiler upgrade isn’t just about making big savings on heating: it also means a warmer home and a reliable supply of hot water.
It’s easy to forget how much you depend on your boiler – until it breaks down. It’s only when you’re suddenly left without basic home comforts such as a hot shower or a warm bedroom that you realise the boiler is a household priority.
If you think you might need a boiler or heating upgrade, you can trust our advice. Our qualified engineer can carry out a no-obligation home heating survey to test the efficiency of your current boiler, and if necessary, recommend the best replacement boiler for your home. They can also check if you qualify for any grants or funding in your area to help towards your new boiler installation.
The best boiler for your home
InstaGroup install only high quality condensing boilers from reputable manufacturers such as Worcester Bosch including Combi Boilers, System Boilers and Regular Boilers. We offer boiler installation services for homes throughout Berkshire, Surrey, Hampshire and Oxfordshire.
We’re committed to the UK’s Net Zero targets. As fossil fuel heating systems such as gas boilers will eventually be phased out, we’re getting ready to offer low carbon home heating alternatives. These include air source heat pumps and solar energy.
If you’re thinking the time is right to replace your home heating system, check with us. We can help you decide what type of heating system is right for you, and will be able to give you more information about the government’s low carbon grant scheme to replace gas boilers.
|Your needs at home||Most suitable boiler|
|You need to use your loft space for a room conversion or other purpose||Combi or System (unvented cylinder)|
|You live in a flat or bungalow (so have very little or no roof space)||Combi or System (unvented cylinder)|
|Your home has more than 2 bathrooms||Regular, System or floor-standing Combi|
|Your mains water pressure is low||Regular or System|
|You want to replace an old boiler to improve an existing conventional central heating system||Combi, Regular or System|
|You want to have hot water available on tap without waiting for it to heat up||Combi|
A combination or ‘combi’ boiler is a good choice when living space is at a premium. It acts as both a high efficiency water heater and a central heating boiler in one single compact unit.
Because a combi boiler heats water directly from the mains when you turn on a tap, it doesn’t need space for a hot water storage cylinder or a cold water storage tank in the roof space. They are very cost-effective and energy-efficient as water is heated instantly, rather than being heated and then stored in a cylinder. An added benefit is that hot water is delivered at mains pressure, which means you could get a powerful shower without the need for a separate pump. Plus, because a combi boiler means less pipework in the home, installation is generally a more cost-effective option.
A combi could be perfect for you if you are hoping to save space whilst improving the warmth and energy efficiency of your home.
A system boiler could be ideal for larger homes with more than one bathroom. It works like a regular boiler, storing hot water, but as many of the workings of the heating and hot water system are already built into a system boiler, installation is faster and easier.
With a system boiler, the hot water is pumped directly through the heating system to the radiators and hot water cylinder. This means you get the benefit of a constant supply of hot water to any number of taps around the home. There is no need for a tank in the loft, so this option is well suited for homes where there is little roof space or where space is needed for a loft conversion.
A system boiler is economical to run and is also compatible with solar water heating systems, which can further reduce household costs.
A regular boiler (sometimes called a traditional, conventional or heat-only boiler) is a good choice for a home where lots of hot water is used at the same time, and where there are two or more bathrooms. It could be the best replacement option for a property that has an older radiator system, as it does not operate with the higher water pressure of a system or combi boiler.
A regular boiler heats your central heating system directly, with the hot water stored separately in a hot water cylinder. These boilers also need a cold water storage tank in the loft to feed into the system.
Regular boilers are compatible with solar water heating systems for further savings on household bills.
Why ‘condensing’ boilers?
InstaGroup only install high quality boilers from leading manufacturers such as Worcester Bosch, who are known for their high efficiency, condensing boiler technology.
Most new boilers these days are condensing or ‘High Efficiency’ boilers. Basically, when gas or oil is burned in your boiler it not only creates heat, it also creates condensation. A condensing boiler is designed to recover more of the heat that is left from these cooling flue gases, which further improves efficiency.
As an example, Worcester Bosch’s Greenstar condensing boilers are around 90% efficient, so they can turn 90% of the fuel they use into heat. That means at least 90p in every £1 you’re spending on gas or oil is converted into heat for your home comfort.close
A new boiler could help save up to £4051 a year on a home’s heating and energy bills.
The cost of installing a new boiler will depend on your home and current heating system. Book a home energy assessment with us and you can find out the most suitable and cost-effective solutions for your household.
Our expert assessor will also check to see if you qualify for any grants or funding to help pay towards upgrading your boiler.
