Heating

This section has what you need to build a complete heating system for a house or flat, from the boiler to the radiator in each room.

• Boilers and pellet equipment — the heat source, running on gas, wood or pellets.
• Radiators and radiator valves — deliver heat to the rooms and let you control it in each one.
• Controls, mixing valves and pump stations — hold the right temperature and split the system into zones, including underfloor heating.
• Safety groups, air vents and flues — the parts a boiler cannot safely run without.

Remember the expansion vessel: how to size it is explained in “Expansion vessel for heating”.
