Use Convector Heater but the way they operate is just that little bit different from radiators

The way you choose to heat your home has an impact on your life every day. You want your heating system to keep you warm and comfortable, but also to be aesthetically pleasing. Here are a few of the other advantages and disadvantages of a convection heater.

Convection heat warms a room from the top down; it uses the natural movement of air which rises when warm, drops as it cools and so on.
Convection heaters warm the air as it passes over a heated coil; some use a fan to draw in the cool air to heat.

Convector heaters provide warmth by pulling air over a heated element. When the heater is turned on, the air is drawn over the element and rises up through the unit and out the top. To speed up the natural convection flow, some models include a fan.

Convectors also rely on hot water, but the way they operate is just that little bit different from radiators. Convectors mainly generate convective heat, drawing in cold air at the bottom through the principle of underpressure which serves to activate a hot air circulation system. Hot water goes through a smaller tube at the bottom of the appliance, which is surrounded by aluminium fins. The fins increase the contact surface area with the ambient air and act as a heat exchanger.

Convective heat is an indirect form of heating. The heating element draws in cold air which it then heats up. The hot air rises up to the ceiling, where it cools down before descending again, allowing the process to repeat itself time and again. The major benefit of convective heat is that it heats up the room more evenly than radiant heat.
