Describe the operation of a fan assisted night storage heater
A fan-assisted night storage heater is an energy-efficient heating device that stores heat during off-peak hours (usually at night) and releases it during the day when needed. It differs from traditional night storage heaters by using a fan to distribute heat more effectively
In an S-Plan Plus heating system, Explain the operation of the two-port valves in terms of controlling the domestic hot water cylinder, and zones for the radiator zones or under-floor heading system zones
. This system is chosen for an installation when there are multiple zones for heating and separate hot water zone
.Each room has its own 2 port spring return zone valve and a room thermostat for each zone
. a cylinder thermostat is used to control the hot water temperature in domestic hot water tank
. The heating zones and hit water must be separately controlled by using a 2 channel programmable time clock
