Unit 1 at Honnacott Barns.


This wet underfloor heating installation took place in December 2018.  Underfloor heating throughout ground floors of all three units.  Pipe in screed clipped to PIR insulation.  The underfloor heating kit  included hardwired Heatmiser neoStats with a neoHub, allowing for smartphone app control.


Manifold and pipework being pressure tested at unit 3 Honnacott Barns.  You can’t beat the quality of a Watts manifold !  One Watts underfloor heating manifold per unit.


Pipes going up and down between different floor levels.


Barn conversions aren’t always straight forward.  The shape of them may result in longer feeder pipes etc, however the main challenge can be a difference in floor level between rooms.  As the above picture shows, steps were going to be built to hide and protect the underfloor heating pipes.  Another alternative could be to cut channels into already existing steps.


Screed is being laid over the Henco 16×2 mm PEX/AL/PEX multilayer pipe at unit 1. 


Pipework was installed at 200 mm centres.



Screed flattened at unit 1, a major step with the ufh and screed both completed at unit 1.
