Heating System
Method of connecting two BoilerMates to one heat source.
If the primary flow and return pipework continuously rises from the boiler to the
BoilerMate the recommended method for connecting two BoilerMates to one heat
source is to fit the BoilerMates as normal but to provide a single check valve on the
branch immediately after each primary pump.
The heating and hot water from each appliance must serve separate zones/bathrooms
within the property.
The electrical supplies from each appliance to the boiler will need twinning so that
the boiler will operate on a call from either/both appliances.
Both primary pumps and the primary pipework sizes should be checked to ensure
that they are adequate for the system that has been installed.
The BoilerMate A-Class appliances will not be suitable if the primary pipework
dips or the boiler is located above the BoilerMate.
