Now that energy prices are rising. My parents do not have much money and we have tried different things in the past to heat our house , because we live in the country we are not connected to the gas supply ,we have to heat our house using souly electricity. in the past we have tried fan heaters and oil filled radiators but it is hard to keep the house from turning damp and cold in the winter,and we feel so cold,we just cant afford to put an electric fire in each room they use so much electricity, would a powerful dehumidifier help ? or are there any other really energy efficient ways to heat a 3 bedroom house
