When
choosing your heater make sure to size it correctly. A heater which
is too large may cost more to operate, may have a greater environmental
impact and may create uncomfortable conditions. On the other hand,
an undersized heater will not provide adequate heating.
Generally, portable heaters are designed for small areas, built in
space heaters for one or two large rooms and central heaters for several
rooms or even your whole house. Sometimes it can be more economical
and practical to use a combination of heaters rather than one large
heater depending on which rooms you want to heat, when you want to
heat them and for how long. As a general rule, the bigger the area
you want to heat, the bigger the heater required and the more it will
cost to run. For room heaters, you can use the rule of thumb of 0.10kW
of heat output per square metre. This is assuming you have standard
height ceilings (2.4m) with insulation. |
