What it is
The Grant EFBS23 is an outdoor frost thermostat for Grant oil-fired boilers. It monitors external temperature and switches the boiler on to protect the appliance and system from frost damage. It is intended for outdoor and external boiler installations.
Signs this part needs replacing
- The boiler does not fire when external temperatures fall towards freezing
- No frost protection operates during cold spells, leaving the appliance and pipework at risk
- The thermostat fails to switch the boiler on at its set point
- Visible damage to the thermostat housing, sensor or cable
- The boiler locks out repeatedly in cold weather
Before you order
- Confirm your boiler model appears in the fitment list above
- Check the part number on the existing thermostat and its mounting position
- Confirm the boiler is an outdoor or external model
- Inspect the wiring and sensor routing before fitting
