Warmhaus combi boilers are suited to properties with reduced space and are mainly located in a bathroom or kitchen and hidden within a cupboard and ensure fast access to hot water from the mains water supply to radiators and taps. Warmhaus combi boilers are energy efficient units with low running costs that are ideally suited to apartments and small to medium sized housing with 1 to 2 bathrooms. Warmhaus combi boilers don’t require hot water tanks or cylinders as a regular boiler or system boiler does therefore making these Warmhaus combi boilers cheaper to install.
