How to install floor heating water distributor? Where is the best place to install the floor heating water collector?
1. How to install the floor heating water distributor
1. Connect the water inlet and outlet
First, connect the water inlet and outlet of each loop heating pipe to the water distributor respectively. , water collector connection. Note that the inner diameter of the water distributor and water collector should not be smaller than the inner diameter of the main water supply and return pipes, and the maximum cross-sectional flow velocity of the water distributor and water collector should not be greater than 0.8m/s; the branch loop of each water distributor and water collector should not be More than 8 lines; each branch loop water supply and return pipe should be equipped with a shut-off valve such as a copper ball valve.
2. Corresponding installation of valves
On the water supply connection pipe before the water distributor, valves, filters and drain pipes should be installed in the direction of the water flow. Two valves are set up before the water distributor, mainly for closing when cleaning the filter and replacing or repairing the thermal metering device; the filter is set up to prevent impurities from clogging the flow meter and heating pipe. The valves and filters in front of the thermal metering device can also be replaced by filter ball valves.
On the return water connection pipe after the water collector, a drain pipe should be installed, and a balance valve or other shut-off adjustment valve should be installed. System accessories should be made of corrosion-resistant materials. Install a drainage device to flush the pipes and drain water before acceptance and during subsequent maintenance. It is best to have a floor drain and other drainage devices nearby.
3. Set up a bypass
A bypass pipe should be set up between the main water inlet pipe of the water distributor and the main water outlet pipe of the water collector, and a valve should be set on the bypass pipe. . The connection position of the bypass pipe should be between the beginning of the main water inlet pipe (before the valve) and the end of the main water outlet pipe (after the valve) to ensure that water does not flow into the heating pipe when the heating pipeline system is flushed.
4. Set up manual or automatic exhaust valves
Manual or automatic exhaust valves should be installed on the water distributor and water collector. Try to install an automatic air release valve to bring convenience to users during future use and avoid air collection caused by factors such as hot and cold pressure differences and water replenishment, which will hinder the operation of the system.
2. Where is the most suitable place to install the floor heating water distributor
1. Multiple locations to choose from
In fact, there are many locations for the water distributor to be installed. As long as the design It can be reasonable. For example, it can be designed into the bathroom. The bathroom is equipped with a waterproof layer. If there is a water leakage problem in the water distributor, the water can flow away along the floor drain without harming innocent people. Secondly, the water distributor can also be installed outdoors. The purpose of this installation is mainly to facilitate later maintenance and repairs, such as on the balcony of the kitchen. If there is dripping, it can also be discharged through the floor drain.
2. Generally installed on the wall below the wall-mounted boiler
The floor heating water distributor is generally installed on the wall below the wall-mounted boiler. The location requires easy operation and convenient sewage discharge. Because there is one outlet and one return water, they must be staggered to a certain position to facilitate the matching of the same outlet pipe and return pipe. The height should be close to the ground, and the installation should be firm and reliable, so that it is not easily knocked out of position by other objects.
3. Installation requirements for floor heating water distributors
(1) The water distributor is installed on the wall and in a special box, usually in the kitchen.
(2) The valve under the water collector should be installed horizontally at a distance of more than 30cm from the floor.
(3) The water supply valve is installed in front of the water distributor, and the return water valve is installed behind the water collector.
(4) The filter is installed in front of the water distributor.
(5) Distributor connection sequence: connected to the water supply main pipe - locking valve - filter - ball valve - tee (temperature, pressure gauge, interface) - water distributor (upper bar) - geothermal Pipe - water collector (lower bar) - ball valve - connected to the return water main pipe.
Where is the most suitable place to install the floor heating water distributor? The installation location of the floor heating water distributor still needs to be analyzed according to the owner’s own situation. It depends on where the wall-mounted boiler is designed to be installed. The floor heating water distributor is generally installed on the wall. The wall below the boiler. The floor heating system is relatively large and complex. The installation of a small water distributor is very particular, let alone the installation of the entire floor heating system. Therefore, users are best to find a professional installation company for installation.
