Bathroom heaters are a type of heating appliance designed for use in a bathroom. A bathroom heater has two main functions: it provides comfort and extra warmth in a room where the floor will often be a cold hard surface, and it helps to prevent any build-up of mould and bacteria by evaporating any humidity in the air. The wet nature of bathrooms means designs of bathroom heater are limited to the wall mounted variety and the under floor variety. Free-standing heaters would pose a significant safety risk in a wet environment, and floor space is often limited in bathrooms, making wall mounted bathroom heaters (also known as bathroom wall heaters) and under floor bathroom heaters the only logical design choices.
Electric Bathroom Heaters
Bathroom heaters usually run off electricity, but there are a wide range of electric bathroom heaters that are available on the market. As with most forms of electric heating, electric bathroom heaters work through the conversion of electrical energy into heat by passing an electric current through a resistor. A common form of electric bathroom heater is the downflow electric heater. This type of electric heater is wall-mounted with the grill facing downwards, out of which the heat is projected by a fan. This kind of bathroom fan heater is often seen mounted above mirrors to remove condensation, and most versions are fitted with a pull cord for ease of operation. A standard 2kw electric bathroom heater is adequate for most size bathrooms, but models with greater output levels are available if desired. Extractor fans are often fitted in this model of bathroom fan heater to aid in the reduction of moisture and water vapour in the air.
Infrared Bathroom Heaters
For a similar price tag, infrared bathroom heaters are also available. These are also wall mounted, and use infrared bulbs to generate heat. Infrared heaters heat up bathrooms quickly and are silent in operation, unlike the bathroom fan heaters. They are also available in a range of outputs to suit the needs of the buyer, and some are fitted with a pull switch to give the buyer the option of different power settings. Many infrared bathroom heaters are also fitted with the means to direct the heat in various ways, depending on the needs of the room. Unlike bathroom fan heaters, they do not generate a flow of air as they do not use a fan, which can sometimes decrease the perceived warmth in the bathroom.
Bathroom heaters are well insulated for safety reasons, and most current other models are fitted with protection against overheating. Some models of electric bathroom fan heaters are set to keep the room at a set temperature once that temperature is reached, allowing for a comfortable, user-defined environment.
Bathroom Storage Heaters
Some storage heaters can also act as bathroom storage heaters. These heaters are seen as a good source of cost-effective, controllable energy as they store heat until it is needed and only use power as long as it is required. They do however require a much larger initial expenditure, and this must be taken into account when considering a bathroom storage heater.
