@JohnMo - thanks! I will have a look at the boiler just to check if there are any shut off valves. I'm going to give it a go today and see what happens! Out of curiosity what would be plan B?

Hi Everyone! First time posting here, I’ve been searching online but can’t seem to find a clear answer anywhere! I’m trying to fill and vent my underfloor heating (UFH) system, which seems like a fairly straightforward DIY job. However, when I checked my manifold, it looks like there aren’t any isolation valves. My question is: can I still fill the UFH system with water using a connected hose, or is that not possible without the valves closed off? If not, is there another method you’d recommend? I’ve attached a couple of photos for reference, but happy to share more details if needed. Thanks team!
