For economic reasons, the cross-section of pipes must be chosen as small as possible, but on the verge of functioning. The cross-section of the collectors themselves should also be small, since all these obstacles can impede circulation, which can increase the hydraulic resistance of the entire system. Such a system cannot be done without a circulation pump, since the coolant must be forced to move. This makes the collector system dependent on electricity and also reduces its vitality.
Heating system installation.
1. In this private house, a floor-standing gas boiler is installed in the basement. The boiler is installed on a concrete screed five centimeters thick.
2. We install metal pipes with a diameter of 32 mm to the “supply” and “return” of the boiler.
3. We install a closed expansion tank on the “supply” pipe.
4. Next, install a manifold on the “supply” pipe.
5.We install a circulation pump on the return pipe.
6. Taps must be installed on both sides of the pump. This is necessary for convenient replacement of the pump if it fails. In this case, you do not have to drain the coolant.
7. We install a tap on the return pipe through which the system will be recharged.
8. We also install a collector to the return pipe.
9. In the basement it is not necessary to install it in a special cabinet, so in this case the collectors are fixed to a metal corner.
10. All collector outlets have built-in taps that allow you to turn off an individual radiator.
11. Radial distribution in the basement is made along the ceiling. In this case, metal pipes are used.
12. The connections of the heating rays to the collectors are made using a metal-plastic pipe.
13. Holes are drilled in the floor slabs through which the pipes are connected directly to the heating device.
14. A metal-plastic pipe was also used to connect the radiators to the heating beams.
I have been using the collector heating system for two years now. There have been no serious operational disruptions so far.
