Let's probably start with what pipe to use to connect the hydraulic separator. This should be done with a pipe that is a multiple of the boiler outlet connections or with a larger diameter pipe. For example, for our boiler with a ¾ connection, the polyethylene pipe diameter should be 32 mm, metal-plastic 26 mm, and stainless steel 22 mm. The switch must be connected using detachable connections. In this case, there is no need to install a valve, as they are already installed on the boiler. Hydrostatic separators typically have 2-3 additional ½-inch holes. An air vent is installed at the top point, as one of the functions of removing the hydraulic separator is to remove air and sludge. We installed a special valve at the bottom to drain the sludge. By slowing the flow of the coolant in the heating system, air rises through the vent. An air vent, and the sludge settles below. We installed a make-up valve on the side, as this is more appropriate so that when making a make-up, we don't disturb all the sludge that has settled below. Two thermometers are installed on the manifold itself to monitor the supply and return temperatures. Many people also install an air vent on top of the manifold, but in our case, it's not necessary since it's not the highest point, and air will still enter the heating circuit. We install ball valves with union nut fittings on each circuit to shut off each circuit when it's not needed. We install the pumps on the supply, and now many questions will arise from people who believe that the pump must be installed on the return. For them, I'll simply answer that the manufacturer's data sheet doesn't specify where the pump should be installed. If you'd like to discuss this further, I'm ready to make a video for you on where and how to install the pump. We installed a pump on the return of the heating circuit. Check valves should only be used when shutting off at least one of the circulation pumps, so that a nearby pump does not create unwanted circulation. If all pumps are running continuously, check valves are not necessary; balancing is achieved by the hydraulic separator. I often see images where coarse filters are installed on each circuit. I don't approve of this, as they create additional resistance and require regular maintenance. There have been cases where the filter clogged and circulation in that circuit stopped, leading to the circuit freezing. This is most common in garages, where you might not notice that the radiators are cold, even though the boiler will continue to operate. Also, for convenience, thermometers were installed on each heating circuit, and stainless steel barrels were installed on the return line, which serve only for aesthetic purposes. We are often asked if we install a mixing unit remote from the separator, whether an additional pump is needed to load the mixing unit. No. There's no need for an additional pump, as the underfloor heating pump will draw as much as it needs from the pointer.
