Quick answer

The honest maths on Pyrivo's running costs – and when heating one room beats heating the whole house.

The simple formula

Cost per hour = power (kW) × electricity price per kWh. Pyrivo uses 0.4 kW on low and 0.8 kW on high.

Pyrivo running costs

ModePer hour4 hours a dayPer month (30 days)
Low (400W)10p40p£12.00
High (800W)20p80p£24.00

Figures assume 25p per kWh and the heater running constantly. Check your own tariff – and remember the thermostat switches Pyrivo off once the room is warm, so real use is normally lower.

Are plug-in heaters expensive to run?

Per unit of energy, electricity costs more than gas. But a gas boiler heats every radiator in the house. If you only need one room warm, a small heater can cost less overall than turning the whole system up. The saving depends on your home, tariff and habits.

Tips to keep costs down

  • Close the door of the room you're heating.
  • Use low mode once the room is warm.
  • Set the timer so it isn't left running.
  • Turn the central heating thermostat down a degree or two.

Frequently asked questions

Low-wattage ones can be. Pyrivo costs about 10p an hour on low and 20p on high at 25p/kWh.

They use their rated power while heating. At 400–800W, Pyrivo uses far less per hour than a 2–3kW fan heater.

It can be when you only need one room warm and turn the central heating down elsewhere. If you need the whole house warm, central heating is usually cheaper.
