What is an underfloor heating manifold?

First, it's useful to know what an underfloor heating manifold is. A manifold ensures that the water in the underfloor heating system is evenly distributed across all the pipes. It's an essential component of underfloor heating. The manifold ensures that the water is pumped through the heating pipes at a constant temperature . This ensures minimal temperature difference in your underfloor heating and high efficiency . The type of manifold you need is determined by the primary heat source. If you have a central heating system (boiler, high-efficiency boiler, or heat pump, for example), the temperature of the supplied water will determine whether we're talking about a low-temperature (LT) or high-temperature (HT) system . Each system has its own type of manifold. Is the house connected to a block or district heating system ? Then you'll need a manifold that is suitable for this and meets the requirements for district heating.

How do you choose the right underfloor heating manifold?

The efficiency of your underfloor heating depends on the correct match between your heat source and the manifold. We distinguish between three main types:

• High-temperature system (HT): For systems with a central heating boiler (supply 60°C - 95°C). Requires a closed mixing manifold with a pump to safely cool the water.

• Low-temperature system (LT/LTV): For heat pumps or LT boilers (supply 35°C - 45°C). A low-pressure header without a pump is often used, as mixing is not required.

• District heating distributors: Specifically designed to meet the requirements of block and district heating networks.

Why choose Magnum manifolds from Vloerverwarmingshop? Our manifolds are made of high-quality materials such as stainless steel, composite, or steel and are compatible with all common heat sources. They ensure even water distribution and a constant temperature range in every zone.

The difference between LT system and LTV system distributors

In low-temperature systems, we distinguish between two systems: the LT system and the LTV system. The difference lies in the supply temperature. As mentioned earlier, the supply temperature of an LT system is between 35˚C and 45˚C . The supply temperature of an LTV system is between 40˚C and 65˚C . Furthermore, an LT system manifold is a manifold without a pump; an open manifold . The LTV system manifold is a mixing manifold with a pump; a closed manifold . With an LTV system manifold, it is possible to mix the supply temperature with cold water, thus lowering the temperature. With an LT system, this is not the case because the supply temperature is at a comfortable temperature and does not need to be lowered.

Block and district heating distributor

Block heating is a heating system with a collective boiler . This can heat, for example, multiple apartment complexes or office buildings. District heating is a heating system in which multiple homes and buildings are heated via an underground network of hot water pipes .
