Designed and manufactured by Baxi, the 624 is a condensing system gas boiler with a central heating output rating of 24 kW. This is a highly efficient system boiler that could help to lower your heating bills thanks to 93% efficiency and an ErP A rating.
System boilers must be installed alongside a hot water cylinder which is where domestic hot water is stored. This allows a system boiler to meet higher hot water demands than a combi boiler which is great for properties with 2 or more bathrooms.
