This tool is a basic heat loss calculator and is provided as a guideline only to indicate the likely size and type of radiator that could be used to heat a room according to your specification. This tool should not be used in isolation to size a heating system and Heatline accepts no liability for any incorrectly sized radiators or heating systems installed as a result of using this tool. To accurately calculate heat loss calculation or determine system sizing, a "Gas Safe" registered or competent installer should be consulted.
