Is this manifold insulation safe?
Hi…
The pipes under the tiles are not insulated when fitted. This under stairs area is becoming sauna when the heating is on.
I insulated the pipes as much as I could to prevent heating this space. I don’t know how to insulate the horizontal bars under the actuators and the flow red stuff.
This will not solve the problem of the tiles here becoming hot so I am thinking of laying a plywood board and leave some gap near the walls to prevent stressing the tiles and pushing them to crack.
But for the pipes… is this safe for the manifold to run like this? Any other tips are most welcome.
