What accounts for the wide square meterage ranges on the Warmup® products?

Warmup has four sizes of heater, a 300 watt, 400 watt, 600 watt and an 800 watt heater, each with a different linear length of heating element.  These heaters can be combined to cover any area that needs to be heated.  By altering the spacing between the wire, the linear length of heating element can cover varying areas.

The installation manual will specify the wire spacing needed in order for the heater to fit your required space.  The Warmup® Underfloor Heater is freeform cable and works in much the same way as the rear defroster on a car (which makes it perfect for fitting around obstacles such as the toilet/vanity unit).

The heating element cannot be cut and the length cannot be altered as their resistances are pre-set at the Warmup factory, and altering them will cause a system failure.
