a Heating

5 Year guarantee^*

Featuring an externally mounted Riello RDB burner and dual thermostat, Grant Vortex Boiler House models are ideal for garage, cellar and plant room installations.

The Grant Vortex Boiler House uses the same unique heat exchanger and turbulator baffle system used in Grant’s other oil boilers. Compact in size and with a distinctive red casing, these Boiler House models can be flued in the same way as utility models. Efficient and reliable, a Boiler House boiler is ideally suited for those installations when a utility boiler is not the best solution.
