BLAUPUNKT Blaupunkr ASF501 Floor fan 40 cm diameter, power 55W

Product Information

We set up each heater in the centre of our test room and run it on the maximum settings, with the room starting at a cool temperature. We monitor how much the room temperature changed over the course of an hour using temperature probes. We found the most drastic changes happen in the first half an hour and increases in temperature become more incremental after that.

We assess how easily each electric heater can be set up and how easily understandable the controls and settings are. We used any handles to lift the heater and move it around. While some heaters can be used straight out of the box, others have complicated program and timer settings.

Oscillation is the other key feature. Nearly all tower fans oscillate, turning slowly from side to side to cover a larger area, but they differ in how wide the angle of oscillation is. Again, the bigger the space you want to cool, the wider you want it – and you can always turn oscillation off if you just want to keep yourself comfortable. How we test tower fans

The fan has an adjustable tilt, three speeds settings and an oscillating feature to make you and your surroundings more comfortable, what's more it fits perfectly onto a table.

Portable electric heaters use electricity, which costs 27.35p/kWh under the current energy price cap. Depending on how effective the heater is, they can take anything from 30 minutes to an hour to notably raise the temperature of a medium-sized room, so if you're only planning on using it until the room gets up to temperature, it will likely cost you between 28 and 55p. And a fourth user put forth the following question: “@bmstores Would you be willing to donate some fans to be shared around to the various children’s wards at Southampton Children’s Hospital? They are crying out for them like a sauna up on the kids’ wards and paediatric emergency dept.” We buy all the electric heaters we test. We put the bestselling heaters from popular UK retailers through these tests: Heating speed, evenness, and accuracy The oil in the radiator acts as a heat reservoir, which stays hot for some time after the heater's switched off. Some are called 'oil-free' and function in a comparable way, just with an internal heating element instead of any oil. Pinning down an exact comparison of how much central heating and electric heaters cost to run is nigh-on impossible, as the factors below are just some of the variables that play a part:

This isn’t the perfect fan for sleepers, as even on its lowest setting it’s far from silent, but it’s fine for cooling down a small living room or taking some heat out of the bedroom before sleep.
