Outdoor Heaters FAQ
Which type of heater is best for large open spaces?
For large or semi-open areas, direct fired diesel heaters offer fast and cost-effective heating. These heaters are only ideal for such spaces, as they produce fumes and moisture.
When choosing a heater for an outdoor area, there are a few options to consider. These include:
The size of the area to be heated.
Ventilation levels.
Fuel or electricity access.
Length of time the unit will be in use for.
Are outdoor heaters safe?
Outdoor heaters are safe when they are correctly installed. However, depending on whether they generate clean heat or not does affect the size and openness they must be operated in. Heaters that do not generate clean heat are not appropriate for smaller areas that are not well ventilated.
When purchasing a heater, make sure to check product specifications and relevant handbooks for guidance.
What fuel options are available for outdoor heaters?
A range of fuel options are available for outdoor heating. This includes electric, natural gas and propane gas. The size of the area and the mobility of the unit may limit these options.
Is outdoor heating energy efficient?
The products we sell are designed to deliver high heat output efficiently. You can increase the efficiency of your heater by ensuring that the correct type and size is purchased for the space that you are wanting to heat.
