STEP Sunroom™ - Heating sunrooms, decks and conservatories

STEP Sunroom™ 12"(30cm) wide radiant heating mat is designed to provide heated floors in sun-rooms, decks, conservatories, etc. Due to the high wattage output (11.0 W/ft (36W/m)) the floor covering is limited to concrete, tile or stone.

Heating sun rooms, decks and conservatories

STEP Sunroom™ has a higher wattage output than the standard residential elements, as these types of applications normally have higher heat losses. A heat loss calculation is required to find out if this system can sufficiently heat the space all year round. This will depend on the type of construction and insulation values of the substrate, ceiling and windows.

Designed to provide heated floors in sunrooms, conservatories, etc.
Ideal for both renovation and new construction
Heat the whole house our just single rooms. A heat loss calculation is required when total heating is expected
Operates on 24 volts (AC/DC); Connect to a power supply, solar or wind power
Floor covering is limited to concrete, tile or stone due to the high watt output
Self-regulating; As the material gets warmer, less electricity passes through the plastic – therefore it is extremely energy-efficient
Easy to install; roll out the elements and cut to size on the job site, connect wires to power supply and elements
Maintenance-free when installed
