​

What is a condensing boiler?

​

Condensing boilers are the most energy-efficient boilers on the market today. They use less fuel and have lower running costs than other boilers. They achieve this high level of efficiency by extracting heat contained in the combustion gases, which would otherwise be lost to the atmosphere. Old, conventional boilers have an efficiency rate up to 60%, which means that they convert 60% or less of their fuel into heat, while the efficiency of new condensing boilers can be above 90% (A-rated). This means huge energy savings and significant cuts on your CO2 emissions and gas bills.

​

There are 2 types of high-efficiency condensing boiler:

​

• System boiler: heats your hot water through a hot water cylinder

• Combination (combi) boiler: gives you instant hot water without the need for a cylinder

 

Each type delivers all the benefits of high-efficiency technology.

 

What is a combination boiler?

​

The high efficiency condensing combi or combination boiler combines both a conventional boiler for radiators and an independent water heater in one compact unit, eliminating the need for a hot water cylinder and cold water storage cistern. With a combi boiler hot water is always available instantly and for as long as you need it.

​

Additional benefits of having a combi boiler include significant saving on your gas bills and the fact that your hot water comes from the mains pressure so you can enjoy showering without needing a noisy pump.

​

What is a system boiler?

 

A system boiler works on the principle of stored hot water. It provides heat for your heating system while being able to heat a hot water cylinder (like a Megaflo). This guarantees simultaneous supply of hot water to all outlets. These type of boilers work with both vented and unvented how water cylinders.

 

System boilers operate on a sealed system like the combination boiler. System boilers are usually compact as all the major components like the pump and the diverter valve are built into the boiler.

 

A system boiler is a great choice for a larger home or family with hot water needs that can’t be met by a combi boiler. You will need a tank in the airing cupboard, though.

​

Which boiler manufacturer do you recommend?

 

We can supply and install any type of boilers. We will assess your individual needs and advise on a suitable boiler. There are several very good central heating boiler manufacturers in the market. We usually recommend A-rated Worcester Bosch boilers for their efficiency and size but we have also found Main and Valliant boilers to be equally good in terms of performance and reliability.
