The UK's exclusive supplier of the PowerBoard — the first 230V far-infrared heating system that installs flush into your ceiling void, with zero visible hardware.
Zoned infrared sidesteps both. Each panel is small (250-500 W), each room runs to its own thermostat, and the duty cycle is typically 20-40%, so a 4 kW total installed system rarely draws more than 1.5 kW continuously. That's a load profile a domestic battery + 6-10 kW PV can actually serve.
We design off-grid systems honestly: a generous PV array, meaningful storage, intermittent infrared loads, and a backup plan (wood-burner, generator hook-up, or small LPG fire) for the coldest week of the year. The result is a home that runs on sunlight for ~10 months and on backup for 2-4 weeks.
Watch our introduction to infrared heating, the technology behind every PoweRad off-grid home installation.
Six reasons solar + battery + infrared works where a heat pump or LPG boiler would struggle.
250-500 W panels with thermostat duty-cycling are gentle on a battery bank. No 3 kW continuous draw, no deep cycles every evening.
Heat the room you are in, not the rooms you are not. Critical when every kWh comes from your own PV and battery.
Daytime PV generation feeds panels directly during shoulder seasons, heat without touching the battery at all.

Cool-touch panels
25-year lifespan
We size for January yield, not annual average. Typical UK off-grid spec: 6-10 kW PV, south or split-orientation.
10-25 kWh usable battery, calculated from your actual daily heating + baseload demand, not a generic rule of thumb.
A wood-burner, small LPG fire, or generator hook-up for the 2-4 coldest weeks. Specified up-front, not bolted on as a panic later.
A 5 kW inverter is plenty for zoned infrared. We size based on simultaneous panel demand, not headline panel wattage.
Each panel on its own schedule, the difference between a battery that lasts the evening and one that fails at 9 pm.
No tanker deliveries, no rural-road LPG haulage, no rising fossil fuel prices. Predictable, weather-driven running cost.
