Virra radiator fan: feel your radiator's heat across the whole room
Most radiator heat rises straight to the ceiling. Virra sits on top and gently pushes it out to where you sit, so rooms feel warmer sooner.
- Warms the room faster from the radiator you have
- Switches on by itself as the radiator heats up
- No tools, no fitting: place it and plug in the USB
- Quiet and low power, around 3 watts
Or from £53 each when you buy a bundle.

Sound familiar?
Heating on, but the room still feels cold
Cold where you sit
The radiator is hot to touch, yet the sofa or bed across the room stays chilly.
Heat stuck at the ceiling
Warm air rises up the wall and collects overhead, away from you.
Thermostat creeping up
So you turn the heating higher and wait longer, and the bills follow.

How Virra works, in three steps
- 1Place it on topRest Virra on top of most flat-topped UK panel radiators.
- 2Plug in the USBIt uses about 3 W, similar to a phone charger.
- 3Feel the differenceAs your radiator warms up, the quiet fans start and spread the heat across the room.
Made for the rooms you actually use



Virra vs a fan heater vs doing nothing
A fan heater makes new heat from electricity. Virra moves the heat your radiator is already producing.
| Virra | Electric fan heater | Radiator on its own | |
|---|---|---|---|
| Uses the heat you already pay for | |||
| Running power | about 3 W | 2,000 W+ | 0 W |
| Warm air reaches where you sit | |||
| Starts by itself when the radiator warms | |||
| Nothing to install |
Will the Virra radiator fan fit my radiator?
It suits most radiators in UK homes. Check yours in ten seconds:
Works on
- Standard UK panel radiators (single or double)
- Radiators with a flat top or top grille
- Radiators under windows or on any wall
Not designed for
- Column or cast-iron radiators
- Heated towel rails
- Electric storage heaters
Running cost
Under 1p for an evening
Virra uses about 3 watts. At a typical UK rate of around 25p per kWh:

Estimate only. Your tariff may differ. A 2 kW fan heater uses over 600 times more power.
Honest expectations
What Virra does, and doesn't do
- Moves warm air from your radiator into the room
- Helps the room feel warmer, sooner
- May let you set the thermostat a little lower
- It doesn't make heat: it only works when your heating is on
- It can't fix a broken or cold radiator
- We can't promise a fixed saving on your bills
