Fully pumped
Domestic Hot Water
system
(PUMPED)
The term for any boiler that uses a pump to
move all the heat from the boiler to every
part of the system is “fully pumped”. As a
rule one pump is used to circulate the water
through valves which divert the flow to the
relevant part of the system (Central heating or
Domestic Hot water). In this type of systems,
both channels of the programmer can work
independently.
Gravity-fed
Domestic Hot Water
system
(GRAVITY)
In gravity fed hot water systems, whenever
the boiler comes on to service heating, there
will inevitably be some circulation through
the hot water storage tank, which will then
heat up. Then there is no possibility to have
independent programs for heating and hot
water.
