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.

Does Virra need installing?

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

How is Virra powered?

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

Will it fit my radiator?

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

How much does Virra cost to run?

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.

Does Virra make heat itself?

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.

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

Can Virra lower my heating bill?

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.

How much does delivery cost?

UK delivery is free on every order. We only ship to UK addresses.

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.

Room airflow without and with Virra on the radiator — Without Virra, heat rises. With Virra, it's pushed out into the room.

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.
