Heat MatPV – Dual-output underfloor heating designed for use with photovoltaics

26-08-2014

This innovative new electric underfloor heating system utilises ‘free’ electricity produced from PV. The dual-output mat has two circuits allowing the system to be run at a low or high output depending on depending on the amount of PV-generated electricity available and the building’s energy efficiency. A 15m2 room area can be heated per kW of renewable energy by running the system on a single circuit at 75W/m2. An additional circuit is integrated into the mat boosting it to double the output (150W/m2) for a faster warm-up time.

The single 75W/m2 circuit running at full efficiency can heat up to a 45 sqm floor area* based on electricity generated from a 3kW PV. This is double the area achievable with conventional electric underfloor heating mats (150W/m2 systems). Heat MatPV is ideal for well-insulated properties and can be installed as a direct acting system or beneath a screed. The screed acts as a storage device, charging up with heat during the day and releasing the warmth gradually in the afternoon and evening or when required.

Energy is converted into heat for floor warming or use as a primary heat source, ensuring home-generated electricity is used on site, minimising energy sold back to the grid and losses from re-purchasing electricity at another time. The VDE approved mats are simple to install without significantly increasing build height and can be integrated into a Part L compliant heating system.

Key product benefits:

• Dual circuit – fit one mat for two output options (run at 75W or 150W/m2)
• Self-sticking mat – no need for double sided tape
• Integrated hidden cold tail connection, therefore no weak spot
• 15 year warranty
• Compatible with a variety of home automation systems and thermostats
• Can be run from mains at 75W or 150W/m2 output at any time

* Heat MatPV can heat up to 45m2 of floor area -the downstairs floor of an average UK house based on a 3kW PV system. According to RIBA’s HomeWise Case for Space report (2011) the average UK house has 85m2 of floor space and 5.2 rooms.
