Today I’m doing day in the life of a plumber. This is video two, so this is part two, on the Viessmann 100 system boiler installation. This is with the Vitocell 200 hot water cylinder. We’re piping this up on a four pipe system.

I’ve started to put some plywood on the wall here. I’ll show you, following on from yesterday’s video I’ll show you the … I’ve put some pipes through but I’ll show you that now.

I managed to dig the concrete out yesterday. That’s part of rubble there. I’ve put some six inch soil pipes in, some underground drainage pipes and then I’ve cemented them all back in. That now gives us a nice sleeve through under the concrete floor. Now I’ve got some pipes that I’m going to put through there.

This pipe that we’re using, it’s MLCP pipe. This has come from Beneath Heat, this pipe, but we’ll talk about that a little bit later.

I’m going to put the boiler up on the wall here now. I’m just going to put a bit more ply on there. I’m going to do that now.

One of the questions that’s been asked was about the damp proof. The damp-proof course is just here. I’m above the damp-proof course on that.

I’ve just put the other piece of ply on there. I’ve connected the bracket on for the boiler so I’m just going to lift that … I’m going to lift the boiler on now.

Boiler’s on the wall now. You can just see there, I’ve just got my laser level on there. That’s me Hilti laser level. Just making sure that it’s all nice and level. I’ve just drawn a little line on there, just so when you start putting pipes on you don’t knock the boiler out. Obviously this needs to look nice and level once you’ve finished.

I’m just going to start doing some of the pipework now. I’m using press fit on the copper and I’m using press fit on the MLCP as well, so that’s a multi-layer pipe. As most people will know, with press fit, obviously check your O-rings. Check they’re in piping. Then you have a machine that just crimps that on. Just reset that. Just make sure your fitting’s on. I try do as many of these just off if I can. You can just check that it’s not come out.

The benefits of this, in my opinion, there’s enough locks and solder going into your pipework. It’s much cleaner and it’s quicker. All in all I think it’s better. I mean it’s much more expensive but it just saves so much time and you don’t get no leaks either.

I was asked what four-pipe means. With a normal boiler you have a flow and you have your return. With a four-pipe system you have two flows if you like and you have two returns. One of the flow and returns pipes directly to the hot water cylinder. Inside the boiler it has a diverter valve, a bit like a combi boiler I suppose, and that moves. Gives the heat to the hot water and it gives it as a hot water priority. You can control that on the display on the boiler but I’ll go into that a little bit more later.

That’s it for today really. I just thought I’d just give you a little bit of an update. I will try and do a daily vlog if I can, just depending on the time. Then I’ll just give you an update of how I’m getting on with this.

Thanks for watching.
