Underfloor actuators working on one system but not on another?
Downstairs I had a 12 port Hetta underfloor system installed by a plumber. Upstairs I installed an 8 port Hetta system myself using the existing pipework which had an old system on. Both systems are now fully Hetta with exactly the same components on (wiring centre, manifold, actuators...

Can this type of system be used for cooling too?
Hi all, I hope you're keeping well in this madness! I wanted to ask a (probably stupid) question. I live in an apartment with underfloor heating, I've pictured what I can of it as I'm sure that'll make more sense than me trying to describe it. During summer, I rely on a mobile aircon unit and...
