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 system, 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. In this
case there is no possibility to have heating without hot water, and the times for both are set using
the CH programme.
You can choose the desired system in the
INSTALLERS MENU.
