How does a direct-fired oil heater work?

A direct-fired heater warms the air with the burner flame, without a heat exchanger in between. The fan pushes air through the combustion chamber and the stream of hot air leaves into the room together with the exhaust gases. With no exchanger and no flue, virtually all the energy in the fuel becomes usable heat — efficiency approaches 100%, whereas an indirect-fired unit loses part of its heat up the chimney. The price for that efficiency is mandatory ventilation: exhaust gases, water vapour and carbon dioxide stay in the heated space.

What is the difference between a direct-fired and an indirect-fired heater?

The difference comes down to the heat exchanger and the flue. A direct-fired model such as the Master B 180 blows exhaust gases into the room and suits only permanently ventilated spaces without people working in them continuously — building shells, halls between shifts, marquees. An indirect-fired model (the BV series) has an exchanger separating exhaust from the delivered air plus a flue pipe, so it can run where people stay all day. The trade-off is lower efficiency and the need to route a chimney outside.

What area will the Master B 180 heat?

At 48 kW of output and 1,550 m³/h of air flow, the Master B 180 covers several hundred square metres of a standard-height hall. The exact figure depends on volume, insulation and outside temperature, so power demand matters more than floor area: an uninsulated industrial hall needs roughly 40–60 W per cubic metre, an insulated building 25–35 W. At 48 kW that works out from about 800 m³ in demanding conditions to close to 1,900 m³ in a well-insulated building.

How much fuel does the Master B 180 use and how long does a tank last?

The Master B 180 burns 4.5 litres of fuel per hour at full output. The tank holds 36 litres, which gives roughly 8 hours of continuous running — a full shift without refuelling. The tank has a fuel level gauge, so you can see when to top up without opening the filler. Real consumption is often lower when the heater runs under a room thermostat that shuts the burner down once the set temperature is reached.

Is the Master B 180 suitable for a garage or workshop?

The Master B 180 works in a garage or workshop only if the space is permanently ventilated and people are not present continuously while it runs. The typical pattern is heating a cold hall before work starts and switching the heater off while the crew is inside. At 48 kW this model is usually too powerful for a single garage — smaller variants of the B series fit those volumes better. For a workshop staffed through the whole shift, an indirect-fired heater is the right choice.

Can the Master B 180 run on HVO 100?

The Master B 180 runs on diesel, kerosene and HVO 100 — hydrotreated vegetable oil. HVO 100 is a renewable fuel with properties close to diesel, made from vegetable oils and waste fats, and approved by the manufacturer with no modification to the unit. At 4.5 l/h, choosing HVO changes neither running time nor heat output, while cutting lifecycle emissions. Whatever the fuel, three filters keep it clean: one in the fuel pump, one on the suction line and one at the tank filler.

What ventilation does a direct-fired heater require?

A direct-fired heater needs a constant supply of fresh air the whole time it runs — open doors, windows or working mechanical ventilation. Combustion consumes oxygen and releases exhaust gases and water vapour into the room, so the space must never be sealed. The Master B 180 has an IP40 protection rating and an overheat thermostat that cuts the burner if temperature climbs too high, but no on-board safety device replaces ventilation. Where a building cannot be ventilated, an indirect-fired heater is the correct solution.

Which accessories fit the Master B 180?

The main accessories for the Master B 180 are a fuel pre-heater, which stops diesel waxing in sub-zero work, and a room thermostat — mechanical TH5 or electronic THD — which shuts the burner down at the set temperature and brings consumption below 4.5 l/h. A service parts kit covers the components that wear during operation. All of these are listed in the related products section on this page.
