INSTALLATION
CENTRAL HEATING
Sealed And Open Vented Systems
The Boilermate OV-PP product range is an integrated thermal store which supplies
space heating from the thermal store. The Boilermate SP and SP-PP product ranges
are hot water only thermal stores where the space heating is supplied directly from
the boiler.
In all three ranges the thermal store itself is open vented and requires a correctly sized
feed and expansion tank. The OV-PP product range requires enough expansion for
the space heating and the thermal store volumes. The SP and SP-PP product ranges
expansion only for the thermal store volumes.
In all cases
•
Combined cold feed and open vent pipe arrangements must not be used.
•
No valve should be fitted in the safety open vent
•
The safety vent must be a minimum of 22mm copper pipe or equivalent.
The Boilermate OV-PP’s space heating system and boiler must be open vented. The
Boilermate SP’s and SP-PP’s space heating system and boiler can be either open
vented or sealed; the expansion system for the thermal store and the boiler/space
heating system are separate.
Maximum Installed Radiator Capacity
The maximum radiator capacity is limited by the power of maximum head/pressure
being delivered by the pump, and the maximum power of the boiler. To maximize the
heat output the pipe diameters must be sized to enable the boiler output to reach
the thermal store and the radiators. The boiler should be sized appropriately for the
system that it is being fitted into.
It is the systems designer’s responsibility to determine what these are.
