Issue with Boiler heating water since radiator flush

wannabecraig

I got my radiators flushed a few months ago, and since then there is some changes in how things work!

One of them makes noise when filling now, this didn’t happen before.

They seem to be hard to balance, so if I turn one up to 5 (with the knows on the side of the rad), one other might not heat properly… this means I have to be careful what I’m turning up/off.

Main issue is that the hot water is not as reliable as it used to be. It used to be if the heating was on for a hour, the water would be very hot, this is less reliable now.

Any ideas?

I was going to adjust the temperature thing on the side of the boiler, but I don’t know what it does.

Boiler, temp control, hot press set up.

After paying probably €500+ for a power flush, you should really get them back to sort it.

BTW why did you need a flush to start with?

Edit: I just noticed what looks like very low pressure on your boiler...and cylinder stat looks set to off. Turn that to 60⁰ and see how it goes.

I got the flush because I was in the house 5 years and hadn't had it done, I thought it was worth doing preventative maintenance.

What is the cylinder stat for exactly?

What steps do I need to take to address the low pressure?

Stat controls domestic water temperature.

You need to increase the boiler pressure using your filling loop if you have one.

Give your service guy a call. He'll talk you through it.
