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.

Power

As stated, the Master BV290 produces 85kW or 290’000 BTU of heating power. But, what does this mean? To put it into perspective, a household radiator has about 1.5kW of heating power, meaning a household boiler of equivalent strength to the BV290 could theoretically heat in excess of 50 radiators. That’s a lot of radiators and, thus, rooms it could heat. However, the objectives are different for the BV290, which is generally asked to heat larger, poorly insulated spaces and to deliver heat quickly.

Lots of heat, quickly

Concentrated in one space, the BV290 is an air heater. This means it pulls air through its body, exposing the air to heat, and warming it up. It then propels the heated air out into the space/environment. Given its power, the BV290 is, therefore, able to deliver substantial heat across a space very quickly.

In describing the substantially less powerful BV77, we suggested it could raise the temperature of a small village hall by 8-10 degrees celsius in less than 10 minutes (excluding all other cooling forces, such as interior shape, exterior temperatures and insulation etc.). The BV290 has 4x the power and double the air flow rate. Meaning it could certainly achieve the same at half the speed, possibly greater. Or, it could heat a larger space just as quickly.

Clean, Hot Air

Producing a lot of hot air is what the BV290 does best. However, in contrast to its equivalents in the Master B-range, the B360, the BV290 is an indirect heater. This means the combustion process, which produces heat energy, is protected. The result is slightly reduced power output, compared to direct heaters, but clean air. Direct heaters, such as the B360 are unsuitable for use in enclosed spaces, with reduced ventilation, as the by-products of combustion are potentially toxic. The BV290 can flue exhaust safely away, while directly or porting heated air into the space you want.

Portable

The BV290 is the largest of the BV range. Yet, Master supply it with a trolley and wheel design to match. The BV290, therefore, is perfectly transportable and manoeuvrable, meaning you can position it in the best position possible for your needs.

Fuel

The Master BV range, along with the B and BF ranges, are able to run on either diesel or kerosene.

How do I get one of these amazing heaters?

The Master BV290 is an indirect diesel-powered heater. Creating clean air, separate to exhaust, they are perfect for construction sites, warehouses, workshops and events tents.

Specification Comparison Chart

Power boost

Only slightly longer (+11.5cm)  and heavier (+6/8kg) than the BV110, the BV170 boasts a substantial power increase from 34kW to 49kW (+15kW). To put this in perspective, an equivalent home boiler to the BV170 would generate enough heat to power in excess of 16 radiators. Or, theoretically, the BV170 could heat 7’600 litres of water by approximately 5 celsius in an hour. (The BV110, over an hour, could heat 5’200 litres by 5 celsius.)

Propulsive Air Heater

The BV170 is essentially a form of convector-fan heater. What this means is the heater draws air into it, warming the air as it is pulled through/past its heating element. The result is a voluminous but gentler heat as the heated air does not heat you per se, but insulates you. Moreover, this heated air can be dispersed quickly across a space. Impressively, for instance, the BV170 pulls 1.8 million litres of air through its little body every hour, heating it up.

100% Clean Air

As mentioned previously, the BV170 is an indirect heater. Indirect heating means the hot air is separate from combustion. Therefore, it is possible to set up the BV170 in a range of ways. For example, a popular means of heating commercial settings, such as events, is by having the BV170 positioned outside the space, porting heat in. This means the heater, which creates noise, is set away from locations where conversation could be happening. Alternatively, the BV170 can be set up right where it is needed, within a space, with a chimney or flue taking the exhaust fumes safely away.

The fact the BV range can create 100% clean air, does mean it can heat closed spaces that its cousins in the Master B range (B180; B230; B360 are unsuitable for.

Going the distance

The BV170 boasts a fuel autonomy of 14 hours. This means the BV170 could run continuously for 14 hours if you needed it to. However, with the analogue or digital thermostat, this should be extended. For example, if your heater only needs to run for half an hour every hour, the time would be double: 28 hours. Be it 14 or more hours, it’s reassuring to know you won’t need to be running back and forward with diesel all the time!

Mobile

The BV170 is a trolley mounted, on a sturdy frame with strong, large wheels. This makes the BV170 a dream to push or pull around, position or reposition as you need it. Over the rougher terrain of a construction site, the smoother surface of a warehouse floor, or the grass of an event, the BV170 is a highly manoeuvrable piece of kit.

Specification Comparison Chart

Duct and Flue your way to 100% clean, warm air

As mentioned above, the BV110 is an indirect heater, meaning the hot air it releases is separate from the air it creates in making heat. Therefore, it is possible to port the hot air into one location and the exhaust fumes safely away to another. This means the BV range can heat closed spaces that its cousins in the Master B range (B180; B230; B360 are unsuitable for.

As an air heater, the heat output is much gentler than a radiant/infrared heater, yet it spreads into the environment much more quickly. What we mean by this is, you could stand nearer to the air output of a BV110 than, say, a Wilms VAL-6. The Val 6, perfect for certain applications, gets extremely hot. The BV110, on the other hand, will not cook your customers should you be hosting them in an events tent. The air and heat disperse.

Serious stamina

The BV110 boasts a fuel tank capacity of 65L and a consumption rate of 3.2 litres per hour. Giving the BV110 a fuel autonomy of 21 hours, the thermostat should only extend this. For example, if you were heating a space insulated enough so the BV110 only ran for half an hour every hour, you would double this time to 42 hours between fuel refills. Even so, at 21 hours of continuous running, you’re not going to be running back and forth with a fuel can to keep it going!

Serious Power

The BV110 packs 34kW of heating power. To put that in perspective, a home boiler of the same size would be able to power approximately 15 radiators (about 2kW each) and a bathroom. The application is different, with the BV110 concentrating that power into a smaller, single but often less well-insulated space. However, its clear to see, for such a compact unit (1.2m in length; 60cm wide and 1m tall), the BV110 packs some serious punch. A nice warm punch!

Serious Convenience

Trolley mounted, with nice large wheels, the BV110 is designed to be positioned anywhere (and, we mean anywhere!). You’ll find the Master BV110 on construction sites, outside events tents and in or around workshops and warehouses. Rough or smooth terrain, the trolley and wheels are there to help you get heat to where you need it, to keep you warm where you want to be warm.

To make controlling temperature easier, the BV110 comes with a thermostat (analogue or digital available). Like the thermostat on your home heating, these regulate temperature by turning your BV110 on and off as it is needed. A handy function, not only does it keep the temperature consistent, it helps save fuel as the machine is not continuously running.

Infrared Heating

Infrared or radiant heat, which the XL 91 uses, has some distinct advantages over air heating, which make it perfect for spot heating. Infrared heat, for instance, transfers heat via radio waves. These waves cannot be disrupted by wind or drafts. They simply travel in a fixed direction. Heated air, on the other hand, rises and can be moved by wind or drafts. This makes spot heating far easier to achieve with infrared as the heat can be directed and focussed on a location with greater accuracy.

Drying and defrosting

The XL 91 is great for drying and defrosting objects. Again, because of its infrared heating technique, heat is actively transferred into materials. Be it your skin, metal pipework or a plaster wall, the heat rays of infrared penetrate the molecules that comprise these things. Transferring energy into these molecules, the object is warmed up.

Transferring heat energy into an object can be particularly useful for defrosting and drying as the object is warmed to a level that will unlock humidity or keep it further away from a freezing temperature.

High-powered heating

The Master XL 91 boasts 29 kW (low) and 43 kW (high) heat settings. To put this power into perspective, it can be helpful to draw a comparison with home boilers, which tend to be in the region of 25 – 40 kW. Depending on the size of a house, the boiler will be selected depending on the number of radiators and bathrooms it needs to heat. The Master XL 91, designed for open spaces, concentrates heat on a small area. 

Efficiency and autonomy

Infrared heaters use less electrical power than air heaters as they do not need to power fans. Moreover, for the power it creates, the XL 91 is remarkably efficient. Fuel burned is turned into heat, which is near immediately transferred into the surrounding space. Therefore, to create 43 kW of heat energy the Master XL 91 only uses 4.03L of fuel per hour. (At 29kW this is 2.7L/H.) With a 60L tank, on the lower setting, the XL 91 can run continuously for 21 hours. (On the high setting it will run for 14 hours.)

Thermostat

The Master XL 91 can be fitted with a digital or analogue thermostat. Easily overlooked, due to their simplicity, these devices are incredibly handy for regulating temperature. Turning the heater off once a higher temperature threshold is reached, the thermostat will restart when the temperature drops. Saving you from doing this manually, when you feel warm or cold, the thermostat naturally increases fuel autonomy, meaning the heater will not need refilling as often.
