Heat-only boilers work by heating water and distributing it throughout the home using a system with various components, these include:
A cold-water tank – typically stored in your loft, this tank will take cold water from the mains and feed it into a hot water cylinder.
Expansion tank - this secondary tank in the loft, known as a 'feed and expansion tank', is in charge of maintaining the correct level of water for the system, accounting for water expansion when the heating system is on.
Hot water cylinder - Water is heated in the cylinder through a coil that is fed off the primary pipework from the boiler, which will then supply hot water to the heating system and bathrooms.
Heat pump - usually installed in airing cupboards, the heat pump provides the power to circulate hot water through primary pipework and the heating circuit to radiators.
All four of these components work in accordance with the boiler to supply hot water to radiators and taps.
Heat only boilers are the perfect pairing for a big household with high hot water demands and many bathrooms. Baths, taps and showers can all be used at the same time.
If you suffer from low mains pressure a heat only boiler is the perfect pairing for your home as the expansion tank will maintain a consistent level of pressure for your water.
Heat only boilers are compatible with solar thermal hot water systems that use renewable solar energy to heat water in the cylinder- reduce your households carbon footprint and reduce bills.
