Powerflush through boiler

omph · 1 Mar 2024

Has anyone done this before ? The CH is clean but the boiler has some gunk and scale build up and I was thinking of isolating and doing a chemical power flush to clear it out (don't want to drain system down).

Don't know how you'd do it without draining down unless you already have flushing connections in place?

I can take off the drain-point and put in some 15mm, so should be doable

How do you circulate it?

If its a Powerflush the unit has a pump.

You said you want to powerflush the boiler only, meaning I presume that you don't want to circulate water throuh the system but only around the boiler so you should pump through the boiler flow or return, through the boiler HEX and back through either the flow or the return/.
