Tool Tip Content - Test
Please note, this is a guide only. A radiator with insufficient output may never raise the temperature to that required. Outdoor temperatures, external walls, insulation, heated adjacent rooms (i.e. above, below and to the side) all play a part.The boiler should be sufficient to supply all connected radiators to the sum of their maximum demand.Larger rooms such as Living Rooms may require more than one radiator positioned evenly throughout the room. If this is the case, divide the required output between the number of radiators needed.Please note in line with current legislation, all our outputs are published at Δt 50ºC
