Diesel heater and construction heater hire

The indirect heater is connected with a hot-air hose to where the heat is needed, so the burner itself can stand outside. You pay for the fuel according to consumption. See also construction heating and ground thawing.

Direct or indirect fired

A direct-fired diesel heater heats the air directly in the flame. Almost all the energy in the diesel becomes heat, but the exhaust gases go into the space along with the hot air. Ours are the Master B100 CED (29 kW), B150 CED (44 kW) and the infrared DC61 (17 kW).

An indirect-fired heater has a sealed combustion chamber and its own flue. The air blown in is heated on the outside of the chamber and never mixes with the smoke. This applies to the Master BV77 (20 kW) and the Remko CLK 50, 70, 120 and 170 indirect heaters, from 42 to 143 kW.

Safety: where people work

Direct-fired heating must be used outdoors, in open buildings or in well-ventilated rooms. Not in enclosed rooms where people stay for long periods. If you need to heat an enclosed room where the crew is working, a tent or a space with poor ventilation, choose indirect-fired.

All the heaters have an electronic flame monitor and overheat protection, and the DC61 also has tip-over protection. With a hot-air hose, the burner itself can stand outside: the BV77 takes a flexi hose of Ø 305 mm, and the indirect heaters have outlets from Ø 300 to Ø 500 mm. All of them can be connected to a room thermostat and keep an even temperature by themselves.

How much diesel it uses

The B100 CED uses around 2.75 litres per hour and runs for up to 16 hours on 44 litres. The B150 CED uses around 4.4 litres and runs for up to 10 hours. The BV77 uses around 2 litres per hour and runs for about 19 hours on 36 litres. The DC61 uses around 1.6 litres and runs for about 7 hours on 11 litres.

The indirect heaters use more: the CLK 50 around 4.5, the CLK 70 around 6.6 and the CLK 120 around 11.8 litres per hour at full output. The indirect heaters also run on HVO100, and the BV77 runs on biodiesel.

Power and moving

All of them need power for the fan and ignition. Most manage with an ordinary 230 V socket, but the CLK 170 requires 400 V three-phase. The DC61 weighs 19 kg and is carried, the BV77 weighs 33 kg and stands on wheels. The indirect heaters weigh from 132 to 375 kg and are moved with a forklift or driven into place.

The DC61 heats what its rays hit, not the air. It doesn't stir up dust and is suited to thawing machines and pipes and drying plaster and paint. Read more about construction heating and ground thawing.
