Underfloor heating manifolds - selection and applications
Underfloor heating manifolds connect multiple heating loops to a single heat source. This category includes brass and stainless steel manifolds for 2-16 circuits, as well as a dial thermometer. The range is intended for installers and contractors fitting underfloor heating systems in homes and commercial buildings.
What you'll find in this category
- Brass manifolds for 2-16 circuits, with automatic air vents and 0-5 l/min flow meters.
- Stainless steel manifolds for 2-16 circuits, with automatic air vents and 0-5 l/min flow meters.
- Ø40 mm dial thermometer with a range of 0-120 °C for monitoring the temperature at the manifold.
How to choose
- Number of circuits: this must match the number of heating loops you are connecting. Every size from 2 to 16 circuits is available.
- Material: manifolds are available in brass or stainless steel. Both versions have the same operating parameters.
- Operating parameters: the maximum working pressure is 6 bar and the operating temperature is 70 °C. Check that the system design falls within these limits.
- System fluid: the maximum glycol concentration is 50%. This is important for systems using antifreeze.
- Dimensions and connections: the manifolds have G1" and 3/4" connections. Dimensions increase with the number of circuits, so compare the dimensional drawing with the space available in the cabinet.
Typical applications
The manifold is the central point of an underfloor heating system. It distributes heating water to the individual loops. Flow meters allow the flow in each circuit to be set and checked. Automatic air vents make it easier to remove air from the system. Manifolds with fewer circuits are suitable for individual rooms, while larger ones are suited to more extensive systems.
Frequently asked questions
How many circuits should the manifold have?
It should have one circuit for each heating loop you want to connect. Brass and stainless steel manifolds are available with 2 to 16 circuits.
What operating parameters are these manifolds rated for?
The maximum working pressure is 6 bar and the operating temperature is 70 °C. The flow meters have a range of 0-5 l/min.
Can the manifold be used with glycol?
Yes. The maximum glycol concentration in the system is 50%.
