Which heater?

What size heater do I need?

A few simple steps to help you work out the size of heater required.

1. Measure the room's size in cubic metres (multiply the width x length x height), e.g. 8m x 18m x 6m = 864 cu. m and then multiply by 35 = 30240
2. Multiply the cubic capacity by 5 for an insulated building and by 7 for a non-insulated structure. E.g. Our building: 30240 x 5 = 151,200 btu of heat required.
3. Convert btu's to kilowatts by dividing by 3412. E.g. Our building: 151,200 / 3412 = 44kw heat.
4. Look at the machines available to find one that suits your needs and covers your btu/hr.
5. Example: If a 3 phase electric heater suits your needs then the H10 42kw is suitable.

Different styles of heater

Electric fan heaters H03 to H10

These are suitable for small offices through to factories. We have single phase 240v and 3 phase 415v heaters to hire.

If you have 3 phase electricity on site then these heaters are very easy to install and position. Some of them you can duct up to 10m, and some have thermostats to make them easy to control. The air is clean and dry, and does not contain any fumes.

The running costs of each heater can be calculated by multiplying the low rating of the heater by the unit cost of electricity you use.

Electric infrared heaters HI2C

Suitable for offices, workshops and production areas. We have 240v and 110v to hire.

The heat is in the form of infrared wave length energy, this energy only heats objects onto which it falls, infrared heaters do not heat up the air around them.

They are ideal for draughty areas, and can project heat up to 6m away and can be used as an effective building dryers in well-ventilated areas.

Gas fired space heaters HG3, HG5, HG7 & HGAT

There are 2 styles - the direct fired and the indirect fired heater. They both use electricity for the fan and propane gas for the heat. HG7 uses natural gas.

The direct fired heaters burn the gas and blow the heat directly into the room and do not vent any exhaust gases. Whereas the indirect fired heaters HGAT exhaust the fumes from the building or they can be positioned outside the building and the heat ducted inside.

They also have no naked flames and deliver warm, clean, dry air.

Gas convector heaters HO1 & HO1C

The cabinet style heaters use no electricity just butane LPG gas which fits into the back of the machine. They are easily portable and put the heat exactly where you want it.

They have 2 or 3 heat settings and are very simple to operate. Suitable for schools, offices and showrooms.

The 2 different styles are the ceramic panels which gives off a maz 4.7kw of heat, but the flame is highly visible and would not be suitable where there is heavy foot traffic.

The catalytic heater has only the pilot light visible and is therefore suitable for areas of people traffic. The heater output is reduced to 2.9kw.

Long wave infrared convection heater HI30

They use infrared radiant heating supplemented with convection fan to produce 26kw of heat. It requires either 110v or 240v supply and LPG propane for the heat. The exhaust fumes can be vented away. No naked flames makes it suitable for marquees, green houses and large workshops.

Paraffin fired space heaters HP5, HI4 to HI7

As with the gas fired heaters, there are 2 styles: the direct fired heater and the indirect fired. They both use electricity for the fan and diesel oil or paraffin for the heat.

They can be setup to run on either fuel (but this needs to be done before delivery).

The direct fired heaters burn the fuel and blow the heat directly into the room and do not vent any exhaust gases. Whereas the indirect fired heaters exhaust the fumes from the building or they can be positioned outside the building and the heat ducted in, they also have no naked flames and deliver dry clean heat.
