So, you will need to run a heat pump for longer to achieve the same level of comfort, and it tends to work better with underfloor heating, rather than radiators.Although much more expensive to install, they can be as cheap to run as gas central heating.Some combi boilers can in any case also heat water in a cylinder.
The pipework may also be connected to a hot water cylinder (tank), which will provide a supply of hot water for bathing and washing.
The most common fuel used in boilers is natural gas, followed by heating oil, and occasionally liquid petroleum gas ( LPG).
