70kW space heater, warehouse workshop garage hot air blower.

Other sizes available

At 70kW the hot air blowing radiator is ideal for heating industrial premises and large open spaces.

Our fan heaters be used in domestic or commercial applications.

Can be mounted from wall or a ceiling, with a powerful fan providing air coverage of around 15m.

The 70kW unit will require roughly a 20 - 28kW boiler to generate enough comfortable heat for an open space area of around 180-200m2 @ 3-4m height.

The unit comes with bracket, holding bolts, a controller with adjustable thermostat and 3 way fan speed adjustment.

Very easy to install, can be connected and work alongside existing radiators.

The fan on the 70kW space heater has the following air flow rate in meter cubes. 

Speed 1 - 1800m3.

Speed 2 - 2400m3.

Speed 3 - 4000m3.

Following scenario is at fan speed 3.

With average water temperature flowing into the heat exchanger being a constant 65 deg C, it now returns at around 40-45 deg C. 

Assuming air entering heat exchanger being 15 deg C will now be heated to 29 deg C.

The specific heat capacity of the above scenario is 17 - 22kW.

A variable constant for the water flow rate is assumed to be around 840 litres per hour.
