Connection of Bathroom Radiator/
Towel-Rail for Summer use
If a pumped circuit is required for the bathroom
radiator/towel rail, the flow pipework can be
teed anywhere into the primary flow between
the boiler and the BoilerMate. The return
pipework can be connected into the 15mm
stainless steel blanked connection provided
adjacent to the boiler pump. We recommend
any radiators/towel rails on this circuit are
provided with T.R.V.’s and that the total heat
output of the radiators/towel rails is not more
than the figure quoted in the table on page 5.
The radiators will only get hot when the
boiler is firing.
It is important that the flow rates through these
radiators is adjusted to the minimum required
at the lockshield valves on the radiators. If this
is not done the performance of the BoilerMate
will be adversely affected.
The height of the water level in the F & E cistern
must provide the minimum head required by
the boiler and must be at least 250mm higher
than the highest point of the system.
Alternatively, if full time control is required
of the Summer/Towel rail circuits these can
be piped as a separate zone from the main
heating circuit with their own zone valve and
programmable room thermostat as shown
in the Installation Section, Zoned Heating
Systems.
