Perfect for keeping small rooms such as bedrooms,bathrooms etc at an ambient temperature,these 240volt 4ft tube heaters really kick out the heat but use just an amazing 180 watts of energy which is less than some lightbulbs! they dont take up much room - just 4ft of wall or floor space and generally cost less than 3p per hr to run,they can also be used in places such as dog kennels,chicken houses etc or possibly conservatories and greenhouses to keep frost at bay,using such a small amount of energy it is possible to use one in a caravan or motorhome for a few hours providing you have an inverter to convert to 240volts and a means of recharging the battery such as a solar panel, these heaters do get very hot though so its best to site one where its not likely to be brushed against or grabbed by children for safetys sake,they come with a 1.5m length of cable and brackets allowing them to be either floor mounted or wall mounted,they can either be fitted with a standard 3 pin plug or they can be hardwired to the mains by a qualified electrician if you prefer to do this,price includes vat and uk mainland delivery, NB: when first plugged in sometimes these heaters let out a wisp of smoke,this is perfectly normal and part of their first time operating procedure.
