Like all installations in our house, heating must be done carefully. For many investors, the correct design and installation of the central heating system does not represent difficulties, but these actions may be made easy errors. Most often they are associated with the overestimation of the size of the heat source and the wrong selection of radiators. So, what are the consequences of these errors?
What does the oversized source of heat lead to?
If we want the installation of central heating to work properly, it is necessary to make it based on the object of the object that will be heated. For this, it is primarily important to produce heat losses, which will determine the power of the heat source. If this action is missing or made incorrectly, the temperature in heated rooms may be too low in frosty days or we will have to take into account the high costs of heating relative to the actual heat need.
The calculation of thermal losses is based on the indicators adopted on 1 m2 of the surface area, can lead to errors to 50%. This is due to the fact that each house has its own characteristics, which often differ from the characteristics of statistical objects. And it is that installers and sellers of heating devices most often turn to such objects. A fairly generally accepted is the value of 100 W / m2 consumption. Based on this, the capacity of the boiler required to heat the house with an area of 200 m2 is 20 kW. However, it should be borne in mind that newly under construction houses have thermal insulation of walls and high-quality window and door fittings that do not allow large heat loss. Then it turns out that sufficient power of heating boilers can be reduced even twice.
What makes the wrong choice of radiators?
Another error that happens when designing and building the heating system is the wrong selection of radiators. For example, radiators may be too large. If they do it equally, the result will be more power than they really need. Such errors can still be corrected. It is enough to adjust the installation parameters. Slightly worse if the power of the radiators is incorrectly selected for some rooms. Then setting the installation can cause big problems.
Other errors made when assembling central heating
Installation of central heating systems can also be associated with other errors. These include, among other things, too high available pressure or improper location of temperature sensors. This first error may have very negative consequences. If the water in the system flows too fast, noise can occur in control components, for example. In radiator valves. https://xannonce.ch
