Im still looking into the best and most economical heating. Would it be cheaper just to run a couple of oil filled heaters in the kids rooms or is it economical to have reverse cycle heating. Does anyone know the cost of having reverse cycle fitted and do you get huge electricity bills since having it. Any useful info would be most helpful. Nights and mornings are getting rather chilly now and it aint even winter yet. We have a gas fire in living room and vulcan heater at the top of the stairs (2 storey) but the rest of the house is freezing. Thanks in advance.
