What is a condensing boiler?

A condensing boiler converts over 90% of the energy used, by using the heat normally pushed out through the flue, therefore it makes more of the fuel it uses to operate, saving you money and helping the environment. With older boilers, as much as 50% was wasted.


What is a combi boiler?

Combi is simply short for combination. This system provides hot water on demand as it operates as a central heating boiler and a hot water heater, so there is no need to have a cumbersome hot water tank, it supplies hot water when and where you need it. This means it saves you money and provides water at mains pressure.


What is a regular boiler?

This is a boiler that is part of a traditional heating system. It heats the water at specified times, this is linked to various tanks. Storage of hot water is vital to this system, the hot water is there when you want a bath, but it can run out. A lot of room is taken up by tanks which can be problematic in small properties.


What is a system boiler?

This is a fast, more economical version of the regular boiler. Similarly, it uses stored hot water, the water is pumped from the boiler straight to the radiators and hot water tank. Many of the components of this system are built-in, so installation is easier, quicker and cheaper.
