What sort of heater should be used?
It is important to warm the air to allow moisture from internal wall coverings and furnishings to be absorbed. The best type of heater to achieve this will depend on your specific situation, however an electric convection heater, fan assisted and thermostatically controlled is a good cost effective option with a small investment. Heat pumps are very energy efficient, but they are expensive to install. Fuel can be wood fired or electric. The exception is gas or LPG heaters which create water vapour and exacerbates the problem when the room cools down. Radiant heaters which heat people and not the air are ineffective.
