Benefits of a sequence controller The Grant 264 sequence controller is designed to manage from 2 to 4 heat sources. These may include renewable technologies such as air source heat pumps and wood pellet boilers or alternatively oil/gas boilers. The controller is able to cope with a mix of fuelsRead More
Feeding heating zones Header systems are a cost effective way of installing multiple heat sources and feeding more than one heating zone which have different temperature requirements. This is achieved by using a small low loss header known as a hydraulic switcher and a distributor. Depending on the system load, two sizes are available (up toRead More
System circulation Zone pump kits are supplied in three pump sizes – 6, 7 and 8 metre head. They also come in either a constant temperature/variable speed or variable temperature/variable speed and complete with a mixing valve and actuator which works with the GEO360 weather compensator. The kits are designedRead More
Systems without weather compensation When air temperatures in the house fall below the setting on the room thermostat, a signal is sent for the boiler to fire and warm the house. Unfortunately a disadvantage of this simple arrangement is that the thermostat only tells the boiler to turn on orRead More
