Oh, right, be very very careful - if the system drains down out of the cylinder and it has a primatic cylinder, you probably know that you need to very carefully about how to re-charge the cylinder.via a primatic hot water cylinder
Not good, you don't want inhibitor into any water that you may use personally, if it did mix then you can inhibitor into your eyes, mouth etc just by washing, I'm sorry to say but that needs sorted out sooner rather than later, did he not know it was a primatic cylinder? Not life or death no, but very undesirable.i had a plumber add a couple of radiators recently and he refilled with inhibitor in the system!
Yes, unless you sealed the system you have, what boiler etc do you have, I presume it's an oldy but goldy if you have gravity HW. The F@E tank could possibly be located in the cupboard too as long as it's above the level of the highest CH pipework, nope, it doesn't need to be large.Would i not need a fill/expansion tank in the loft?
If you're thinking of replacing your Primatic with a fully indirect cylinder (a good idea in the circs!) it's worth converting to a Honeywell C-plan as on attachment. Needs a 28mm motorised valve but you'll need to drain the system down and modify the cylinder primary side anyway. Much more flexible and potentially more economical than your current set-up.Would i not need a fill/expansion tank in the loft? It sounds like thus might be the way to go tbh.
I'll get the plumber back to drain down and refill the system in the meantime.
I'm also still trying to get my head around the draining/refilling of this bathroom rad thats on the hot water gravity side of the boiler and how its separated from the CH side of things.
