COMBI BOILER REVIEW – BOILER INSTALL AT HOME, https://www.cchleeds.co.uk/services/boiler-installation Baxi 600 Review, Baxi 624 630 636 Full installs of the new Baxi 636 combi boiler on two zone at my home in Leeds. The new Baxi 600 range of Combi Boiler. I’m going to install a new boiler in my own house. So, at the moment we’ve got a boiler that’s here, and we want to put a fridge in this cupboard. So, what I’m going to do is I’m going to board the wall out behind, and we’re going to move the boiler and put it on the back wall. Well, we’re going to install a new boiler, but we’re going to put it on the back wall.
I’m also going to put a weather comp sensor on this, so we’ll have the weather comp so that in the warmer weather, the flue temperatures will be lower. So, that’ll save us money on our gas bills as well.
I’m also … I’ve got some zone valves, so we’re going to put it onto an S-Plan. So, for an S-Plan, we want a zone valve for downstairs, and then we’ll have a zone valve for upstairs. And then obviously that’s how you would control the heating system. And then you would use the nest for thermostats then to control them.
I’m also going to power flush this system, so I’m going to connect it onto the old boiler and flush it with the old boiler in place.
So, as I board the wall out in here, I’m looking at where I put my supports, and I’m looking at the template for the boiler. So, this is a Baxi 600 boiler, so it’s the new 636 boilers. So, I’m just looking where the screw holes are, and I’m going to put the supports where that is.
So, I’m just using the template so I can mark and connect all the pipes together. You see there? Just got the bypass on that.
Right, so we’ve got some of the pipes in now. So, just to explain what’s going on here, so the Baxi 600 has space so you can put the pipes up the back. So, what I’ve got here, I’ve got our flue there. This flue goes up to there, and then it goes across there. And we’ve got a bypass because we’ve got this on an S-Plan, we’ve got a bypass. And then that’s the return.
So, then also at the bottom there we’ve got this filter. So we’ve got an Omega filter on there. So, that’s the return, back into the boiler. And then from the top there, so if we go around the flue, we’ve got two zones. And then we’re just going to have a manual air vent out there, just so we can bleed that section of pipework.
So, we’ve got one of our zone valves there, and I’m just going to pop another zone valve here now. And then just to show you on the zone valve, most of you will know this already, but there’s just an A and there’s a B. So the zone valve only goes one way. So, you need to make sure you put it on the right way around. So, on this one, the A comes down from the flue, in that direction, so when you look at the valve there, the flue would go that way.
So, we’ve got the Baxi 636 that we’re installing in this house, in my house. So, you can buy the pipes from Baxi that are pre-made, that’ll come up the back. And you also get this bracket, and that obviously will clip the pipes. And then when you look … so you can put 22 up the back nice and easy there.
So, now I’ve pre-marked where I’m putting all the pipes. I’ve made it up as a template. Because it’s press fit, I can now unclip it off, and then what I’m going to do is I’m going to take the paper back off. And I’m also going to remove the clips off there. They were just to hold it in place while I connected it all together.
So, I’ve just lifted the boiler onto the bracket now. So, I’ve just got our filter connected in now. I’ve just done code. And I’m just going to do the pipe.
So, we’re using this new Hilti NPR 19A. So, that’s a 22-volt press gun for this. And I’m just doing gas now. I just wanted to show you these gas fittings. So, the gas fittings have got a yellow/gold ring.
So, I use press fitting on most of my installs. One of the benefits of press fitting is you can make it all up away from the boiler if you need to. Also, there’s no flux going into the system, so it doesn’t take us long to flush the system out after.
Also on this, I’m going to put a shock arrester on. So, I’ve got some lock tight 577, so instead of using PTFE, this is a mile better than PTFE. So, all you do with this is get your thread and just squirt a little bit on your thread like that. And then once you’ve got some on your thread, you just tighten that on to your fitting.
So, it’s really easy to use press fit. So we just get our fitting, look inside, check that they are in, and make sure they’re not damaged. Connect it onto the end of our pipe. Some manufacturers will give you it’s like a little instrument you can use, like a bit of plastic, and then you can mark this pipe here. Baxi 636 624 630 Combi boiler, New Baxi Boiler
