Water convectors

Difference between water convectors is water convectors (fancoil). Types and operation.

Among the types of heating, thosewaterthey are widespread. Undoubtedly the most popular are radiators, however water is used as a heat carrier in different types of heating such as:

  1. Radiators - Radiators
  2. Convectors
  3. Fan coils or fan coils, fancoil
  4. Radiant panels

Water heaters can be of different types, the most common are:

  • A cabinet
  • Baseboard (or plinth)
  • Wall
  • Floor convector

Hot water convectors

If the radiators are adjusted with the thermostatic valve, the temperature of thewater convectorit can take place either through a valve (manual or thermostatic) or through the outlet deflector.

The heat is diffused by means of characteristic finned coils which can differ in number and ranks. The heat transfer mechanism of thewater convectorsit's atnatural convection. This notion is important because this feature differentiates them fromfan coilsorfan coilwhere the heat transmission mechanism is aforced convection.

Fan coils or fan coils

THEwind convectors, just like iconvectors, have finned coils but at the base there is afan responsible for the forced diffusion of heat.

If you've heard ofwall-mounted convectors orceiling convectors, most likely it was systemsfancoils (fan coils).

In fact, the water convectors can be installed:

  • On the floor
  • Wall
  • ceiling
  • to false ceiling

Although it all depends on the model, ifan coil units or fan coils, are generally larger than thewater convectors and are often used for bothheatingthan for thecoolingdomestic. Compared to convectors, however, water convectors have some disadvantages such as:

  • They produce condensation
  • They need more maintenance (they have a filter)
  • They are generally noisier due to the fan (they produce 30 to 50 db)
  • The fins are more prone to failure

After seeing what thedifferences between fan coil unitsiswater convectors, let's focus on the functioning of the latter: convectors.

Water convectors: how they work

THEconvectorswaterthey need a water supply, use water as a heat carrier and see a rather efficient operation. Compared to radiators, they have this significant advantage: the supply water is at lower temperatures, so it will take less energy to heat the house.

The water convector requires a source of hot water which can be:

  • boiler
  • heat pump
  • solar thermal system

The important thing is that the water has an average temperature suitable for the efficiency of the convector being installed. On the market they are present water convectorsvery efficient, even iwind convectorsthey are very efficient: they are able to heat using hot water at a low temperature (even 40 ° C).

How a convector works?

Convectors have heating bodies that release heat bynatural convection. They are made withfinned coilsand feature natural draft devices to increase the heat output of the "finned coils".

Sometimes iconvectorsthey can be installed on the wall, integrated into the home. In this context, the draft device is made by directly exploiting the niche (recess) of the wall.

Operation varies slightly according to the type of installation but in any case a sort of "chimney effect" is used, capable of diffusing heat in a natural way.

Better radiators or water convectors?

THEwater convectorsthey have a lower thermal inertia compared to classic radiators. In addition, installation and purchase costs are also lower. Among othersadvantagesto mention there is the possibility of completely hiding the heating body by integrating it into thewallsor infloorhome.

If you are considering the purchase of aconvector daikin, ferrolifor any other house, consider the sizing well. Keep this general rule in mind:Lower delivery temperatures increase the cost of the system but also increase the efficiency and footprint of the appliance.

Against, hot water convectors with high flow temperatures they have higher operating costs (they consume more upstream of the system) and have other disadvantages such as:

  • They contribute to the formation of areas with warmer air on the ceiling and colder air on the floor. This is true regardless of the type of installation because hot air, with a strong convective motion, is always pushed upwards. Think about that by installing a system floor convector you can fix this problem is incorrect.
  • They cause irritation to the respiratory system.
  • They risk blackening the walls near the heating bodies.
