Badly Installed Ideal Logic Combi Boiler. Also Ideal Mini Combi Boiler.
I'm going to show you some badly installed Ideal Logic combi boilers and then I'm going to show you why you should pay more to have your boiler installed correctly. I'm going to show you some good quality Ideal Logic combi boiler instals as well. Yeah, let's go and have a look.

To help the trainees here, I'm going to try and go through as many of the faults as I can see. So this is in a loft, it's in an unheated area and it's an Ideal Logic 24 kilowatt combi boiler. We've also got the benchmark log book to refer to on this one. So as I said, this is an Ideal Logic, it's installed up in a loft. So I'm just going to test the inlet pressure on the gas. Just have a look at the blow pipe there. So the PRV on this has been soldered. Now that should be a compressured fitting. It shouldn't be soldered in an Ideal Logic. Also, the pressure gauge on an Ideal Logic, it should be on the floor, not the return, so it should be on the lefthand pipe.

So if you have a look at the inlet pressure now on the gas, just going to put it upon to high, its on low, I'm going to put it up onto high. So its on high now. Okay, so the pressure has gone all the way down to 14.5 millibar, 14.3 millibar. If we refer to the benchmark document, when this boiler was installed on the top righthand side there in heating mode, allegedly it was a 20.1 millibar for the central heating and for the hot water, it was at 19.9 millibar and we're getting between 14.2 and 14.3 millibar.

And when we go to the gas metre and we test the working pressure at the gas metre, it's at 22 millibar. So we've got, what's that? Seven and a half millibar drop over the installation. So what that tells us is we've got an issue with the gas pipe sizing. We should only have one millibar drop maximum over the installation for pipe sizing. So that's something for you to check and if you're a trainee, this is what happens if you don't instal the pipe sizing correctly. This has got a lot of 15 millimetre pipe and the boiler's up in the loft. And yeah, it's just wrong. It should be 22 millimetre pipe, most of it, and then you might get away with a little bit of 15. But just shows how important is to size the pipe work correctly.

Always make sure that you read the installation instructions for the boiler. And this part of it tells you about the gas supply and I think people get confused here because they see that the Logic will work as low as 14 millibar, but the regulations clearly say you're allowed one millibar over the installation. So please, check and read the installation instructions correctly.

I did say this was an Ideal Logic combi boiler, it's actually an imini combi boiler, but it's the same boiler really. Ideal just put different badges on and if we look at the common set pipe, we can see it goes through the wall in small pipe, in overflow, so clearly that's not installed correctly either. Also, the pipe should be lagged, so it should be big pipe unlagged. Again, refer to the installation instructions.

Lots and lots of faults on that one. There's a few that I've not mentioned. One is the flue, but what I'm going to do is I'm going to show you some different pictures and videos of flues as well, as well as some good quality instals as well to show you what you should be expecting when you get a new boiler installed and as a customer, why should you be bothered?

Well, the main reason why you should be bothered is that if the boiler's not installed correctly, then there's a good chance you're not going to have no boiler warranty. So you might have a piece of paper that says you've got a 5, 7, 10, 12, 14, 50 year warranty, whatever it says, but if the boilers not installed correctly, then there's a good chance that the manufacturers will not honour that warranty. And rightly so, in my opinion. A lot of these faults, a lot of boiler faults are down to how they're installed. So if the bile is installed correctly, flues correctly, then there's a good chance it's going to last a long time.

What I'm going to do now is I'm going to show you some other boiler faults, and then I'm going to show you some good quality instals as well. Show you what you should expect when you have a new boiler installed.

This next one is an Ideal Logic and it's the flue. Now it's very, very clear in the installation instructions on an Ideal Logic that you can not have any white on show. So if you see the actual, where the white joins to the black part of the plastic, that actually needs to be sealed. This is how it should be installed on an Ideal Logic. No white on show, but please refer to the installation instructions.
