Gas Combi Boilers

With space-saving considered as a premium feature for most homeowners, combi boilers do not require the need for a bulky hot water cylinder, thus saving valuable space. Gas combi boilers are fed directly from the mains water supply and as such offer on-demand, hot water as soon as a shower or hot tap is turned on, perfect for frantic mornings in a busy household. Aside from being convenient, combi boilers are highly efficient as they only heat water that is required via an internal heat exchanger and are more cost-effective when it comes to installation than other boiler types. With a wide range of models with higher kW outputs for larger properties, there is a suitable combi boiler to suit your central heating needs. Read our detailed guide for more information on what is a combi boiler.
