How to find the right   Heater
Buildings and Halls
 

For the decision which kind of heater and the required heat capacity the kind and size of the room that needs to be heated are decisive. The following general rules give you guides for the often required quick decisions - in case you have a heat requirement calculation from an architect at hand this one should be preferred.

 
 

For buildings and halls a general rule assumes a max. temperature rise (difference between the lowest anticipated outdoor temperature and the highest inside temperature) of 30 K (30°C). For other temperature rises you have to reduce or increase the heat capacity by 17 % for every 5 K (5°C)

Not redeveloped rooms in old buildings or shells before installation of insulation
Oil- or gas heaters: Volume (m³) x Factor 0,058 = Req. heat capacity (kW)
Electric heaters: Volume (m³) x Factor 0,041 = Req. heat capacity (kW)
Old buildings with average insulation
Oil- or gas heaters: Volume (m³) x Factor 0,040 = Req. heat capacity (kW)
Electric heaters: Volume (m³) x Factor 0,030 = Req. heat capacity (kW)
New buildings with insulation
Oil- or gas heaters: Volume (m³) x Factor 0.025 = Req. heat capacity (kW)
Electric heaters: Volume (m³) x Factor 0,020 = Req. heat capacity (kW)
Green houses and tents
 

For the calculation of the required heat capacity of green houses and tents different to buildings and halls not the room volume but the entire outer surface should serve as base for the calculation.

 
 
 
 
 

This simply because the heat loss of such constructions reacts proportional to the outer surfaces.

 
Green houses and tents without insulation
Oil- or gas heaters:
Outer surface (m²) x Factor 0,0064 x Temp. rise = Req. heat capacity (kW)
Green houses with double glassing and thermo tents
Oil- or gas heaters:
Outer surface (m²) x Factor 0,0037 x Temp. rise = Req. heat capacity (kW)
