temperature of 111°C ± 3°C.
The Kitchen/Utility boiler control panel
is fitted with an ON/OFF switch, boiler
thermostat control knob and the manual
reset button for the overheat thermostat.
An optional plug-in programmer is
available to purchase from Grant

operating times for central heating and
hot water, Part No. EPKIT.

The Boiler House dual thermostat, on
