UFH Manifold Insulation

[Dave Jones]

why dont the manifold manufacturers sell an insulation package that matches the manifold ? Some pre-formed insulation out there that do a part of the manifold but none that do the whole thing including the pipework exiting the slab.

 

Another job for a celotex box......

My manifold sits in a cupboard and the heat given off warms (doesn't make it hot) the cupboard, used for storing bed linen and towels etc. They give off very little heat as the flow temp should only in the high 20s most of the time and early 30s if really cold outside. Even in cooling duty the condensation is nil with a flow temp down to 11 deg.

 

If you were installing UFH in an old building and flow rates were 40+ all the time, the story would be different.

 

Really wouldn't waste your time effort.

UFH loop is needed for part O cooling. insulation is important.

[JohnMo]

If you flowing at temperature that cause manifold condensation you are flowing at temps that will cause floor condensation - which is something you need to avoid.

 

A PIR box is easy to do. Even easier if you have no pump mixer or zone valves. As no reliability issues to consider by boxing in and trapping heat.
