Convectors: advantages and disadvantages


Convectors: advantages and disadvantages. An overview of the consumption and types of convectors on the market.

THE convectors modern radiators have advantages over traditional radiators, but also disadvantages. Whether the first (advantages) or the second (disadvantages) prevail depends on the type of environment to be heated and the type of comfort to be achieved.

How much does a convector cost

The purchase cost of a convector, as well as its consumption, can vary greatly depending on the manufacturer, model and type of power supply.

Purchase prices start from a few hundred euros to rise and touch much more demanding sums. The installation cost must then be added to the purchase cost.

Advantages of convectors

The main advantage is that within the individual convectors no liquid can circulate which can freeze if the temperature drops below zero. So in winter they can be left off without problems, unlike radiators which must remain at a minimum or emptied together with the heating system.

This factor makes the convectorssuitable for second mountain homes that are used only in short periods of the year.

Another advantage of the convectors is that the heat is created quite quickly, so the heating is rapid, almost immediate.

The newer models, which do not take up much space, are usually equipped with an adjustment knob and may have timers to program on and off.

Another positive thing of the convectors is that they do not require maintenance, apart from cleaning the parts that may be subject to clogging every now and then. Finally, these devices do not risk dispersing harmful discharges that can saturate the internal environment - this is an advantage compared to stoves - and even a possible gas leak in the circuit would discharge gas into the open air (in the case of gas convector).

Disadvantages of convectors

The main drawback of the convectors it is linked to the fact that they exploit the physical principle of hot air that rises and cold air that descends, therefore: the temperature on the floor will be lower (cold feet) and warmer above. Between the floor and the air one meter above the ground there can be a difference of even a few degrees, not just a little.

Another disadvantage can be that of consumption. If the goal is to save gas or otherwise contain electricity bills (in the case of electric convector), a lot depends on the type of convector which you choose (see below). Overall, however, the expenditure on heating with a convector system it is generally in line with that of a radiator heating system.

Types of convectors

There are water, electricity and gas ones. The difference between one type and another depends on the 'substance' underlying the operation.

THE convectors gas they are recommended for medium-small rooms, i electric convectors and water are recommended for larger spaces.

Almost always i convectors gas and those electrical have an adjustable speed fan that pushes the air out of the device, which facilitates heating but increases the consumption.

For the convectors gas you need an external air intake and a smoke outlet, which usually coincide in a single hole of about 12 cm (an external wall outlet). Logically, a gas connection will be necessary.

From a maintenance point of view, the least demanding are probably theelectric convectors.

Electric convectors and gas convectors, having no liquid in the circuit, they are perfect for mountain farms where, if the temperature drops below zero degrees, the water can freeze.

Water convectors

For thewater convectorconnection to a hot water production system is required: boiler, heat pump and solar thermal system. The hot water produced in this way enters theconvector. Compared to classic radiators, iwater convectorsthey require water at lower temperatures.

Awater convectorit can be “natural ventilation” which has a further advantage over traditional radiators: it heats more quickly and requires less hot water as well as lower temperature water.

On the other hand there are thecosts. Acost water convectormore than one radiator (radiator). In choosing thewater convector, keep in mind that it offers low consumption but that for installation it will require major building works for the addition of the delivery pipe that connects the boiler toconvectors.

Convector: consumption

THEconsumptionof aconvectorthey can vary a lot both according to the operating principle and from model to model and again, also according to the mode of use. The habits of the final consumer as well as the environment to be heated greatly affects consumptionof any device suitable forheating.

Talking aboutelectric convectorsconsumption can range from 600 to 2,400 wh based on the number of resistances that the end user activates.

For themethane gas convectorsto the fuel consumption it will then be necessary to add the electricity consumption when forced ventilation is present (now in all models). In this case, 50 - 100 watts of electricity absorbed per hour of operation must also be added to an average of 0.5 cubic meters of methane. In the absence of thermal dispersions, it is better to keep active iconvectorsand set an ideal temperature using a thermostat.

Betweenconvectorsto morelow consumptionwe point out the latest models on the market that run on water and gas. In this case, thewater / gas convectoruses water at 40 ° C to heat the house at low temperatures. A good saving on consumption if we consider that the radiators work with water that reaches 70 - 80 ° C.
