Furnace fan powered by a Peltier element. Increases the efficiency of the furnace and quickly warms up the room

Everyone knows a fan heater of the "Veterok" type: a spiral heating element with a fan inside. Despite its small size and power up to 2000 W, it is able to quickly heat a large area up to 20 m2 and effectively maintain the temperature. Price example:

It is efficient because of the fan. Forced air circulation in the room occurs, warm air from the heater mixes better and the room warms up more evenly. This is not the case in convectors.

By the same principle, some apartment owners increase the temperature in their rooms:

But this method is not the norm. If it is cool in your apartment, then you need to find out the reason: is there a problem in the temperature of the radiators (air or low coolant temperature), is there a problem in the windows (blown out) or the size of the radiators is not designed for this room.

Some have steel fireplaces in private homes.

The solution is beautiful, but it takes a long time to heat a room with such a stove. And for faster heating, an idea with a fan would just help. And such that it would fit into the style of this stove, and even would not require power supply. Such fans are produced:

Works independently of the Peltier element. Those. when the oven is cold, the fan does not rotate. The oven heats up gradually and the fan starts rotating smoothly. No power cords need to be routed to the oven (which may melt). Size: 110x65x125 mm. Material - anodized aluminum. Several blade colors. Rotation speed - up to 1350 rpm. Noise level - 25db. Working temperature: 50-350 gr.

• For those who find it convenient to buy on aliexpress - a similar model here. And even with delivery from a warehouse from Russia. This means that they will be delivered within a few days.

The photo shows where the Peltier element (thermoelectric converter) is installed to power the electric motor. Not on the plane of contact between the body and the stove. There, the element would overheat and quickly fail. The Peltier element was placed higher on the body. The lower part is heated by the infrared radiation of the oven and the rising hot air. And the upper part of the element is cooled by the air flow from the fan blades. A temperature difference appears and the element delivers enough electricity to rotate a small electric motor.

Heat-resistant wiring. The electric motor has almost no contact with the body (fastening through one clamp). And since there is a constant blowing of air, then overheating is not threatened. The engineer here thought everything out well.

The efficiency of this fan can be depicted in the following figure:

Because the fan mixes the heated air in the room, then sitting by such a stove, you will not feel the heat only from infrared radiation, but also from warm air coming from the oven, as from a heat heater "Breeze".

A few real photos of how the fan looks on the stove:

The furnace is heated - the fan rotates, increasing the efficiency of the furnace. Does not heat up - does not rotate. Control, you do not need to turn it off.

I believe that this is an affordable device for increasing the efficiency of the furnace and faster warming up of the room. Because without wasting energy from the outside, you increase its heat transfer and, what is important, the rate of heat transfer.

How long the Peltier element will last - no reviews. But since there is no overheating of the Peltier element, and the outer casing of the furnace will not heat up above 300 degrees, the fan will work for a long time. And if it ever fails, then the element itself has a low cost.
