Massive massive improvement after shoving mains water through it all. Heats up so quickly now! Except for a little problem with some air being drawn into the boiler. But after bleeding the boiler, all is 100% better!!
Yeah 18mm chipboard and 15mm oak flooring. One of those zones with this exact amount of wood heats up lovely, and it's a big zone. Which is why I don't understand the no heat elsewhere. About to try and force some mains water through the zones to bleed again. Question is my water main is 7 bar...
I've used spreader plates so just went to the spacing that those allow. As they are made 200mm apart. So couldn't actually decrease the spacings. I was only going on what the manufacturers had said on their garb.
No it doesn't have one :-s I'll try starting again from beginning filling mains. And take it from there. It's gotta be that! I'm sure! It's the only thing that differed from manufacturers instructions.
Ah yes. Well that's where we didn't follow the exact manufacturers instructions.. As I've now read after searching fault finding online. As the rennovation is still ongoing, the UFH is the only circuit fed off the boiler.
So we filled from filling loop, one zone at a time, releasing the blue...
Yeah unfortunately couldn't get away from it :(
What's best way to get a reading on loop temps? A handheld thermometer? Hehe.
So if flow and return were wrong way round, wouldn't it just shut off the boiler?
If the mixer was faulty, I wouldn't see a temp of 60degrees at the manifold right?
All measurements of zones linear.
Flow temp from boiler 65 degrees
Blend valve set at 60 at manifold.
Flow and return 22mm copper.
Manifold temp showing at 60degrees on return.
Recently installed Underfloor heating. in a renovated Timber clad building with suspended floors.
The walls are all filled with 100mm insulation in between and 50mm over studs.
Floors are 50mm celotex overboarded, with aluminium spreader plates and 18mm t+g flooring on top. 15mm engineered...
