Boilers by brand

Boilers by brand

We stock leading boiler manufacturers including Baxi, Glow-worm, ECA, Navien, Ideal, Worcester Bosch and more. To help you find the condensing boiler brand you're looking for, we've categorised them here by the manufacturer.

In the UK the use of condensing boilers is now compulsory unless certain criteria for exemption can be identified by a qualified heating engineer. Condensing boilers are water heaters in which a high efficiency (typically greater than 90%) is achieved by using the waste heat in the flue gases to pre-heat the cold water entering the boiler. Fuelled by gas or oil, they're called condensing boilers because the water vapour produced during combustion is condensed into water, which leaves the system via a drain.
