The VFMi series of fan assisted storage heaters provides the optimum in comfort and controllability.


With a heat storage capacity of 32 kWh or 48 kWh, VFMi heaters are ideally suited to heat large areas in domestic, commercial and industrial situations.

Both heaters are fitted with a highly sensitive capillary bulb thermostat, which accurately controls the amount of heat taken in by the unit core during available charge time. This heat is then stored in the core due to the super efficient insulation, allowing just a small amount of mild static heat dissipation through the case.


When the room is occupied and full heating is required, quiet slow-running fans force air through the heater core and out into the room through a mixing damper, providing a rapid uniform heat up. As soon as the temperature reaches the preset level the fans switch off.

Once set, your VFMi heater will continue to automatically maintain the desired room temperature.

Experience permanent background warmth

No other heating system gives you the double advantage of permanent background warmth together with automatically controlled heating. On cool summer evenings, or if there is a sudden drop in temperature, a direct acting element fitted in the air mixing chamber provides instant back-up heat.
