a. appropriate choice of heater power for the size of the room
Really, heater power can be accurately calculated by the architect of your house or apartment. Or ask your installation specialist for advice if you cannot rely on the architect.
To select the heater power yourself, consider the following:
- the size of your bathroom;
- the number of external walls (the more walls, the ‘colder’ the room);
- the number of external windows (the more windows , the ‘colder’ the room);
- insulation of external walls (the better the insulation, the warmer the room);
- whether there is, for example, floor heating in your bathroom
heater power = 100 – 150 W × m2
* previously, the above formula was applied, but at present, most new buildings are properly insulated, and less power is required.
b. proper heater location on the wall
Heating is most efficient when:
- the heater is as close to the floor as possible, as heated air always rises and cold air descends;
- the heater is hung underneath or close to the window;
- there is no ventilation grid directly above the heater which will draw heated air out, thus decreasing the room temperature.
It is not advisable to mount heaters directly above bathtubs, close to washbasins, showers or toilets. Mounting in such locations considerably reduces the life of the heater’s finish.
c. heater power can be temporarily reduced when drying damp clothing, etc.
If you want your heater to serve as a dryer, e.g. for damp towels, remember that:
- hanging cloth items to dry will reduce the heater’s power output, so consider using a heater for a larger area (i.e. with larger dimensions);
- you might need an electric heater to help you dry clothing outside of the heating season and which you can use all year long.
