Feeling hot hot hot

The advantage of direct heat generation for open and semi-open environments is the sheer efficiency and volume at which they operate. So long as the space is well-ventilated (which open and semi-open spaces tend to be), direct heating does not separate combustion and heat production. This means no heat is lost when trying to separate exhaust and heat. Plus, it means the heat is easy to expulse into the workspace. The result, therefore, is 3’300m3 of heated air being produced an hour.

Right where you need it

The B360 might be the biggest of the range, but they’re still mobile. Mounted on a sturdy chassis and frame, boasting chunky wheels and handles, the B360 is still easy to position where you need them.

Easy to use

After you’ve got your B360 right where you need it, using it is as simple as turning it on. Available with either an analogue or digital thermostat: set it to your desired temperature and let the heater do the rest. If the temperature drops too low the heater will strike into action. Once back up to the desired temperature, the heater will go into standby.

3 reasons why you should get a Master B model?

1. They are simple to use, with no-nonsense controls.
2. They throw out incredible amounts of heat.
3. They are incredibly portable.

Bonus reason: they look like jet engines.

Direct vs Indirect Heating

The difference between direct and indirect heaters is simply how these heaters expel heat. The way to think about a direct and indirect heater, therefore, could be the distinction between an open and closed fireplace. A direct heater is similar to the open fireplace and the indirect heater is similar to the stove. 

Why is the direct heater similar to an open fireplace?

The direct heater is similar to the open fireplace as it expels heat by throwing out the air that it uses as part of the combustion process. Of course, in a direct heater, the combustion process is cleaner and better protected than in an open fire. 

The positives of direct heating are that the heat efficiency is as high as it possibly can be. Less energy is lost as the heat does not have to be transferred. Therefore, the temperature and rate of heat expulsion can be much higher for a direct heater than for an indirect one. The higher efficiency often leads to greater airflow too, meaning the hot air can be thrown quicker and further into an open space.

The negative of direct heating is that the hot air from the heater is essentially the exhaust of the heater. Direct heaters, therefore, are only to be used in well-ventilated spaces.

Direct heat generation means the B230 will keep hands and bodies warm no matter the environment. There are no greater efficient means of generating heat. So long as the space is well-ventilated and needs rapid and vast heat supplied to it, the B230 is the solution.

Portable

The B230 is easy to move. Mounted on a sturdy frame, with chunky wheels and handles, they’re easy to move and position right where you need them. 

Easy to use

Once you have your B230 where you need it, it is as simple to use as turning it on and setting the temperature. Available with either an analogue or digital thermostat, once turned on and set to the temperature you want, the heater will turn itself on and off as required. If the temperature drops the heater will strike up and raise the temperature. Once it reaches the desired temperature, it will shut off until it is next required, saving fuel.

Heat the whole of your working day (and more)

The B230 can run continually for 10 hours. Therefore, even if you like your open workspace to be like a summer’s day in the costa del sol, the B230 will be able to keep you warm across your working day.

Why is the indirect heater similar to a fireplace stove?

An indirect heater is similar to a fireplace stove as the heat generated in combustion is separated from the heat expelled by the heater.

The positives of indirect heating are that the hot air is clean as the exhaust is expelled separately. An indirect heater, therefore, can be used to heat closed spaces with less ventilation (so long as the exhaust is flue or outside of the space you want heating). It is common, therefore, for an indirect heater to be placed externally to a space, where the exhaust can be freely dispersed via a chimney. Or, for the heater to be fitted with a flue that pipes the exhaust to a space where it can disperse. The hot air is then flued into the location you want heating up.

The negative of indirect heating is reduced efficiency in comparison to direct heaters. The heat generated in combustion needs to be transferred across a protective material, before being expelled from the heater. As efficient as it can be, this transfer process naturally incurs a reduction in heating potential.

3 reasons why you should get a Master B model?

1. They hold up to 10-hours worth of fuel.
2. They boast no-nonsense controls: one switch for on and off (+ optional thermostat).
3. They have a portable design, with sturdy wheels, making them easy to transport around work sites.

Being a direct heater (see Direct vs Indirect Heating below), the B180 can generate heat with great efficiency and with great volume. The B180, for example, could fill an Olympic Swiming Pool (2’500’000 litres) with heated air in 97-minutes. Or, what we like to call a football match, plus Fergie time. You can see then, that the B180 is more than capable of keeping you toastie on a cold winter’s day.

Direct heaters, including the B180, must be used in well-ventilated spaces (see direct vs indirect heating).

Easy-to-move

B180s are lightweight (34kg) heaters. However, to make moving them even easier they are fitted on a trolley with large wheels, making it easier for you to move and position your heater right where you need it. 

Simple to control

Once positioned where you would like it, you can set your B180 to a temperature that you would like it to maintain. Simply set its thermostat to your desired temperature and crack on with your work. The B180 will then regulate the temperature of your workspace, keeping your fingers nimble and thawed for tinkering.

Keep yourself warm the whole working day

Brim its tank and your B180 can run continually for 8 hours. Therefore, even if you like your workspace to be a sauna, the B180 can keep it toasty all day long. If you prefer not to sweat in winter, then it’ll go even longer: using its thermostat to regulate a steady temperature.
