This job , I used Wundafloor. The pipe us the same as unipipe, the manifold and flow restrictors ate the same as speedfit and others. It's a decent thermo valve and a grundfoss pump.
I've done 50-60 installs with them and to now had one flow restrictor leak, a faulty actuator head and one pipe that had a cut in it. Thus was obviously found when filling and pressure testing before screed was laid.
Free plans, 30 day account and order befor 5pm for next day.
