A combi-boiler is specifically designed to produce both hot water and heating from the same appliance. Combi-boilers are an excellent addition to your home due to its compact nature and efficiency, as there is no need for an additional cylinder tank! Therefore, they are particularly useful for small flats, and homes with only one bathroom.
A system boiler is where hot water and heating run on individual circuits and are controlled via zone valves. The hot water will be stored in a cylinder-shaped tank located most commonly in an airing cupboard, garage or loft. However, for older models, this system usually requires an additional feeding tank located in the loft.
More recent systems are called unvented cylinders, which are fed through mains directly without the need to fit an additional tank in the loft. System boilers are particularly useful for larger homes with multiple bathrooms.
