Warmup Commercial Grade Heating Cable (Constant Wattage), 240V 625'L, 3400W, 14.2 amps. Covers 155-260 sq ft of heated area

Warmup’s WODH cable is used specifically for thermal storage heating in building foundations. There are other more specific applications for this cable (see Applications) but its main purpose is to heat a thermal mass, which can then release the heat over a long period of time. This is particularly useful for buildings operating on solar power or benefiting from dual tariffs or electric rates (low cost at night, high cost during the day).

The WODH is a twin-conductor cable (no return) in an advanced fluoropolymer jacket with a standard output of 5.5W/linear foot. Thanks to its structure and build, it cancels out all electro-magnetic field interference.

The cable is installed in dirt, sand beds or tied to a lightweight mesh and embedded in a concrete foundation pour. It is suitable for residential and commercial environments, such as basements (residential) to replace a water-based system, or cooler slabs (commercial) to prevent slab heaving due to cold temperatures.

In order to best plan for the required cables and outputs, the first consideration is the building’s heat loss. Please provide this information to Warmup, or request that Warmup performs a heat-loss study of your project. To complete this, Warmup will need the following information: 

• Intended use of the building
• Length, width and height of the building
• R-Value of wall and roof insulation
• Number, sizes and R-Values of doors and windows
• Lowest expected ambient temperature
• Building maintenance temperature
