For new and replacement boiler installations

For new and replacement boiler installations you must have either: a timer or programmer with a room thermostat and thermostatic radiator valves or a programmable room thermostat and thermostatic radiator valves. Unlike a conventional heating and hot water system, a combi system does not store domestic hot water it heats water directly from the cold mains, as you use it there’s no requirement for a hot water cylinder, no tank in the loft (and so less risk of freezing and flooding).
