Hi, My plumber recommended this company [[www.economy-radiators.com/ for electric radiators] We need to heat a garage conversion (it had already been converted when we bought the house) to make it into my son's room. We also need to heat the water. It was used as a work studio so although there's a loo, it doesn't have a shower and doesn't have hot water. What are my options in terms of heating the room and water? Gas could be brought from main house and a combo boiler fitted but plumbers advise it's not worth it and just go with electric. I'm scared of the electricity bill! If we go for electric, should be opt for an electric shower or fit an immersion heater? Sorry about all the questions!
Do you know much about the conversion - when it was done? To what spec? Garages tend to be a bit gerry-built so I'd want to be sure that it had been insulated as much as possible before dealing with what sort of heating it should have. You can get very efficient immersion heaters (they are very heavily insulated so the water stays warm for a long time and, in a smaller tank - 50l or 70l - it only takes about 20 minutes to heat it up) but heating the room solely by electricity would make me a bit nervous unless I was sure the heat would stay inside.
All electric rads cost the same to run. To save money when you have electric heating you need to increase insulllation all round - roof walls, ceiling, windows.
There are so many ifs and buts I don't think there is one right answer of what would be best. If it is well insulated then fitting electric Under floor heating can be a good solution. Fairly cheap to fit and you can have timer and thermostat - which you really should have. You must go for the "backing board" which sends the heat up and means the floor will heat up within 30 mins.
If it was highly used and gets hot in summer I might invest in a air-air heat pump which is air con in summer and heater in winter. This is electric but (possibly) fr cheaper to run than electric rads. Installation could cost around £1,000.
