Ranking of manifolds for underfloor heating

Added: Monday, 12/29/2025


More and more people are opting for underfloor heating, especially since it provides convenience of use. It is also maintenance-free. Investors also gain greater air humidity and, at the same time, less dust. Underfloor heating works with modern systems. Undoubtedly, its most important element is the distributor, which can be used to connect circuits, installation zones and radiators into one system. Get to know the ranking of these essential devices for underfloor heating .

ONNLINE distributor for underfloor heating 11 circuits

ONNLINE distributor for underfloor heating When choosing a floor heating manifold , you need to remember how important its quality and durability are, as well as its adaptation to the number of circuits. The Onnline manifold for 11-circuit floor heating is definitely worth attention. You need to know that it is best to use 5-6 meters of heating pipe per 1 m2, with one loop not exceeding 150 meters. This manifold can be installed in both surface-mounted and flush-mounted cabinets, as well as below floor level. It is equipped with compression fittings for multilayer pipe, as well as rotameters and thermostatic heads. The manufacturer has used a really strong body, which is thick-walled and brass, finished with a ball valve. The dial thermometer is located in the valve. To speed up the work, all assembly elements such as rubber bands and screws are included. This manifold uses a venting and draining unit, where the vent is automatic.

KAN-therm InoxFlow manifold with 10-circuit system

The KAN-therm InoxFlow 10 circuit manifold is also worth mentioning. It is based on stainless steel beams with a larger internal diameter, but a smaller wall thickness. This gives even greater operating possibilities. You can also increase the efficiency of underfloor heating. You need to pay attention to the precise regulation that flow meters allow. They are equipped with a circulation pump and automation elements. If repairs are necessary, all you need to do is use Allen keys. This solution will work very well in both homes and public buildings. The InoxFlow manifold is mechanically resistant and highly resistant to loads.

Purmo INVEST manifold with rotameters - 5 loops

Purmo INVEST manifold with rotameters for underfloor heating INVEST manifold with rotameters - 5 Purmo loops is another model that meets strict quality standards. It is equipped with a manifold rotameter, which is designed to measure, but also precisely regulate the water flow in the circuit. For greater savings, a reduction nipple is included in the set. It is also worth noting that this device has been subjected to an air tightness test at a pressure of 10 bar. It also has a setting memory function. In addition, the valve inserts are adapted for mounting thermoelectric heads. To facilitate installation, the manufacturer has used mounting brackets with a quick assembly and disassembly function. Investors will also appreciate this manifold because of the graduated vial cleaning function. Special rotameters are quantitative indicators of media flow and thanks to them you can control energy consumption, and thus also reduce heating costs. This solution really does save money. Thanks to its compatible dimensions, it can be placed anywhere.

Valvex MINI BASE 10 -circuit distributor

Efficient work is also ensured by the MINI BASE Inox K2-10 G1"-G1/2" 10-circuit Valvex manifold . It can be used in both hot and cold water installations, as well as in central radiator and surface heating systems. Its durability and reliability have been confirmed by a 25-year warranty. Importantly, it works very well even at pressures of up to 1 MPa, and at working temperatures of up to 95 degrees Celsius. It is equipped with manifold handles and a manifold plug, as well as an automatic air vent valve. It is made of strong stainless steel. It also has a wall mounting bracket, which speeds up work.
