Hi all,
We are getting closer to having our UFH pipes laid on the ground floor (in 50 mm liquid screed). My design is as shown in the attached image (150mm centres) , however have been told that its not the best way of having it and a spiral design would be better and give more even heating and less chance of any cracks. Is that right or is my design perfectly adequate?
All the runs are less than 80m long, I didn't want to go more than 150mm on the centres as I wanted to improve heat up times on the system and the plan was to run the UFH at as low temperature as possible so that the boiler is condensation mode all the time while the heating is on (If anyone has any further information on system design in that respect it would be much appreciated).
Thanks
