Nothing on the walls. Every room on its own smart thermostat. Slim white PowerBoard panels on the ceiling warm people and everything in the room directly, instead of heating the air first. Supplied and installed across the UK.
On our standard basis: about 5 heating hours a day, panels drawing power about 38.5% of that time because the thermostat cycles them, at 27p a unit. These are modelled estimates; colder homes and colder weather mean more.
How the bedroom figure is worked out: 0.75 kilowatts x 5 hours x 38.5% = about 1.44 units a day, x 27p = about 39p. Over a 240 day heating season, about £94. We keep this rate fixed, set just above Ofgem's price cap when we chose it (26.32p, October 2026).
At full output, a 750 watt panel costs about 20p an hour and a 250 watt panel about 7p. The thermostat switches it off once the room is warm, so most hours cost less.
Switch a panel on when you come into the room and it reaches full output in under 10 minutes. Once the room is up to temperature, the thermostat switches it off, and back on for a few minutes when it drops a degree. On a cold evening it runs flat out at the start and then ticks over.
A battery charges overnight and runs the panels in the evening. For homes with a battery and no electric car, overnight rates of around 13p a unit are typical; about 11% is lost in storage, so each unit back costs about 14.6p.
Assumes the battery covers each room's evening heating. Solar PV is the next layer on top, mostly outside the depths of winter.
Every electric heater turns one unit of electricity into one unit of heat, so no electric heater costs less per unit than another. What changes the bill is how the heat is delivered and controlled.
The Energy Saving Trust's view is that a well controlled infrared system will probably cost less to run than standard electric panel heaters, and might cost less than storage heaters or electric underfloor heating, depending on the controls. UK government research summarises a study where people were as comfortable with the air about 0.6 of a degree cooler (DESNZ, 2025); that helps the bill only if you turn the thermostat down, and our installation manual's advice is that most people can set it a degree or two lower than they would with a radiator.
Gas and heat pumps cost less per unit of heat. For a whole house heated all day, every day, they will usually cost less to run, and we will tell you so. PowerBoard is for the homes and rooms where that is not how heating gets used, or where a boiler or a heat pump is not the right fit: flats, extensions, loft rooms, home offices, homes off the gas grid, and anyone who wants heating with no pipework, no outdoor unit and nothing to service.
It depends on how many rooms you heat and for how long. On our basis (about 5 hours a day, the panels drawing power about 38.5% of that time, 27p a unit), a bedroom with one 750 watt panel costs about 39p a day and a living room with two costs about 78p. These are modelled estimates.
At full output and 27p a unit, a 750 watt panel costs about 20p an hour and a 250 watt panel about 7p. The thermostat switches the panel off once the room is warm, so most hours cost less than that.
A battery charged overnight at around 13p a unit costs about 14.6p for each unit it gives back. For a bedroom with one 750 watt panel that brings about 39p a day down to about 21p, if the battery covers the evening heating.
Not per unit: every electric heater turns one unit of electricity into one unit of heat, and storage heaters charge on a cheaper night rate. The Energy Saving Trust's view is that a well controlled infrared system will probably cost less to run than standard electric panel heaters, and might cost less than storage heaters, depending on the controls.
Not per unit. Gas and heat pumps cost less for each unit of heat, and for a whole house heated all day they will usually cost less to run. Infrared suits rooms and homes used in parts, homes off the gas grid, and people who want no boiler, no pipework and nothing to service.
A 750 watt surface panel is £382.80 including VAT and a 250 watt integrated panel £298.80 including VAT, both supply only, plus a hardwired WiFi thermostat for each room at £82.80 including VAT. Your own qualified electrician can fit them, or we can put you in touch with an installer from our network.
