The Electric Radiator Calculator UK helps determine the appropriate wattage needed for electric radiators based on room volume and insulation quality. Proper sizing ensures efficient heating and energy consumption.
The calculator uses the power calculation formula:
Where:
Explanation: The wattage factor varies based on insulation levels: 34 W/m³ for good insulation, 45 W/m³ for average insulation, and 55 W/m³ for poor insulation.
Details: Correct radiator sizing is crucial for energy efficiency, comfort, and preventing underheating or overheating. Oversized radiators waste energy while undersized ones fail to heat the room adequately.
Tips: Measure room volume (length × width × height in meters), select insulation level based on your property's insulation quality. All values must be valid (volume > 0).
Q1: How Do I Calculate Room Volume?
A: Multiply room length × width × height in meters. For example, a room 5m × 4m × 2.5m has a volume of 50 m³.
Q2: What Determines Insulation Level?
A: Good insulation = modern double glazing, cavity wall insulation, loft insulation. Poor insulation = single glazing, no wall/loft insulation. Average = some insulation measures in place.
Q3: Can I Use This For Multiple Rooms?
A: Yes, calculate each room separately as different rooms may have different volumes and insulation requirements.
Q4: What About Room Orientation And Windows?
A: North-facing rooms and those with large windows may need slightly higher wattage. Consider adding 10-15% for such rooms.
Q5: Is This Calculation Suitable For All Room Types?
A: This provides a general guideline. Bathrooms and kitchens may have different requirements due to moisture and appliance heat.
