5.8 Heating Circuits
There are two types of heating circuits: pump and mixing. They must be carefully designed and
installed, especially in the case of using more heating circuits.
5.8.1 Manifolds
This is a piping element designed in such way that the individual heating circuits affect each
other as little as possible. The flow speed of heating water inside the distributor / collector
should not exceed 0,5m/s. The distributors can be independent with integrated thermohydraulic
distributor, or integrated in the accumulation vessel. We recommend using manufactured
distributors which make the installation faster and easier. Typical implementation in the
following images.
