Why radiator size is important
Choosing the right radiator can help reduce energy bills, for example too large a radiator will increase bills unnecessarily, but too small a radiator will be too cold and will be constantly running at maximum. By performing a Heat Loss Calculation, you can establish the radiator Watt / BTU outputs required for a particular room taking into account any heat that will be lost through walls, windows and ceiling. This ensures that your rooms will be heated comfortably and efficiently.
*Please note: Heat Loss Calculations are only estimated and are based on information you provide. The Heating Calculator can only process the most common factors that affect heat loss and may not take into account all factors relating to your particular requirements. Therefore any results provided by the Heating Calculator should not be considered 100% accurate, and we accept no liability for any errors resulting from the estimates given.
