Technical Specifications
Size Calculator: Measure the exact “net” m2 heating area. Exclude any floor obstructions such as benches, WC areas and shower trays. E.g.: 6m2 les shower tray (1m2), WS (.5m2) and bench (1.2m2) = 3.3m2 x 150w = 500 watt heating element required.
Note: With concrete floors under 5m2 we recommend using a formula of 180w/m2. The calculations are based on an electrical rate of 29 cents per kW/hr.
