Virra radiator fan FAQs

Virra is a triple-fan radiator booster. It sits on top of an ordinary radiator and gently pushes the warm air that would normally rise to the ceiling out into the room, at sitting height.

A radiator fan is a small accessory that sits on or near a radiator and moves the warm air it produces into the room, instead of letting it rise straight to the ceiling.

No. Virra doesn't heat anything. It moves the warm air your radiator already produces out into the room, so it only works while your heating is on.

They can help a room feel more evenly warm when the radiator itself is heating properly, because they move warm air to where you sit. They can't fix a radiator that stays cold.

Three small, quiet fans in one slim unit.

Yes. Virra starts automatically as the radiator warms up, so you don't need to remember to turn it on.

It's designed to be very quiet – quieter than a typical fridge – so it's suitable for bedrooms and living rooms.

Virra helps a room feel warmer sooner, which may let you set your thermostat a little lower. Savings depend on your home, radiators and habits, so we can't promise a figure.

Virra suits most standard UK panel radiators with a flat top. It isn't designed for column radiators, towel rails or electric storage heaters.

No. Place it on top of a panel radiator and it's ready. There's nothing to screw in, no plumbing and no electrician.

Yes. Virra is designed for standard UK panel radiators, single or double, with a flat top or top grille.

No. It isn't designed for storage heaters, column or cast-iron radiators, or heated towel rails.

Yes, as long as the top of the radiator is flat and there's a little space above it, for example under a window sill.

One per radiator you want to help. Most people start with the rooms they use most, like the living room and bedroom.

Yes. There's nothing to fix in place, so you can lift it off and use it on another radiator.

Via the included USB cable. It uses roughly 3 watts – about the same as a phone charger.

Very little. At about 3 watts, running it for 8 hours costs well under 1p at a typical UK rate of around 25p per kWh – roughly £1 for a whole winter of evenings. This is an estimate; your tariff may differ.

A typical fan heater uses 1,000–2,000 W, so at around 25p per kWh a 2,000 W heater costs about 50p an hour. Virra uses about 3 W because it moves existing warmth rather than making new heat.

It's designed to sit on your radiator while the heating runs and starts automatically as the radiator warms. As with any electrical item, follow the quick-start guide and keep the cable tidy.

It's low-power and runs from USB. Keep the cable out of reach of chewing pets and small children, and don't let anyone poke fingers into the fans.

You need a USB power source, such as a USB plug adapter or a USB port nearby.
