Yeah it will probably have half the Life of the Potterton Neta heat had

Thank you

@@loving-plumbing corners were cut! There were two bottles in the new boiler box. Cleaner and inhibitor Fernox red and blue cap. They were not used. Can they flush the boiler without using them...the rads were drained of water via a hose stuck on water pipe in hallway...I was keeping an eye on the bottles (not watching them constantly, as I don't like that personally in my job) but at the end before they left I felt the bottles and felt they were full , caps still sealed. I think coz of the time needed to flush/clean they didn't do it. The guy working on the boiler did use a spray bottle which I found out is an inhibitor, but boiler was not run for hour whatsoever, maybe just 20mins tops. They felt the rads warm up and bleeded them that's it. You mentioned it was imperative to do it in your vid. I didn't like the fact they didn't do it. I didn't call them out straight away as again I didn't want to tell them how to do their job. So I waited for the inspection next day to mention to the inspector. I told them that the workers didn't use the bottles, they agreed that it should have been done. The paperwork was even filled in ticking the boxes stating that they had used the cleaner and inhibitor. Also they were cheeky enough to stick the stickers from the bottle onto the side of the boiler but without inputting the date used. Why would they do that? Purely to save time? So the boiler breaks down so they are called out more often? I am a housing association tenant. Or is it not imperative? Anyway, the inspector arranged for an operative to attend the next day, I wasn't in but my misus stated all they did was come in and pour a bottle of inhibitor into the Fernox TF1 Sigma Filter. That was it. No cleaner used, no running on full power for 1/2 hour etc. Boiler working fine. But I'm guessing old sludge remains inside rads/pipes. Its probably just going to damage boiler sooner rather than later. Any thoughts?

Why do you care? It's not your boiler,you didn't pay for it did you?

Only if you are having more then one heating zone. But usually probably not if converting.

Power flush is not mandatory. A chemical flush is.

Thank you 👍. I'm pretty sure they are just called Aquagas M-Press fittings. Merchants like Williams have recently started to stock them. Cheers.

I wouldn't recommend it to be honest. Unless the micro bore is already pressurised

@@loving-plumbing How can you tell if the microbore is pressurized? I'm in the same boat as the person who asked the question. I have a regular (very very old) boiler with microbore and I don't know what to do for the best. Thanks.

​@@laganas2008I'm in the sanw boat, did we get an answer to this please 🙏

Correctly sized rads with traditional trv’s. Condensing boiler. Normal programmer and room stat. Basic stuff is the best. Why complicate things.

@@JayGasEssex because on/off controls are inefficent

Hi. The best way is to get a large measuring jug and run the tap for a minute. This will tell you how many liters per minute you have. Make sure it's from the cold main. I like to use a big tilers bucket. Alternatively you can buy a weir gauge which is a plumbers measuring device. Flow rate generally can't be increased by the supplier but you can upgrade your incoming main size. The minimum you want is a 25mm blue MDPE pipe. Otherwise pumps and accumulation may be necessary

3 Bar is pretty standard I would say. Thanks 👍🏻
