to learn from experience, is one radiator interchangeable with all others? eg is a 600×900 a standard size?

The installer of the radiators is me, hence these questions. Which is obviously suited to economical and convenient installation hours. Just need to be sure I'm not going to bodge the expensive work of my Corgi, or be bound in to an exorbitant service contract.

I take it you don't approve of Magnacleans?

Madrab, you sound like you know what I'm up against. However, outside is still too high when I could just use the crawl space, risk a little splashing and need less flushing as that will be where most of the heavy sludge collects. Saves renting powerful pumps if I'm careful and regular. Oh...

I thought in an effort to avoid warranty claims boiler manufacturers would require an annual power flush certificate? Like new cars are warranted providing you regularly attend the manufacturers rip off service centres. No?

new ch system going in now. old boiler is DHW only. maybe that is best considering a power flush could be £350 and warranty may specify annually.

FiremanT, iso is an isolating ball valve, correct? Don't know what DC means. As for going through walls outside, no can do, to thick. Under floor is where it's lowest. I'll buy 2 drain cock type A and return one if I don't need on flow AND return. What I need is a good way to connect to...

Forgive my ignorance, but what is the advantage of NOT having a TRV on one radiator?

Hi, I'm speaking in general but if specifics are needed my first choice boiler is Potterton Gold 24k. I understand CH sludge can block the heat exchanger and was wondering how onerous the maintenance schedule is for the warranty to be valid? For instance could I get the boiler installed with...

no, there not. all are feed from underneath the suspended ground floor. it's a one floor job.

Thanks for a proof read, really need a computer set up as my phone really takes the pi$$ with it's cockless dictionary.

I'm new to central heating and just had a quick butchers at the wiki here. That advocates a single drain cock with a hose attached for draining. I was thinking of using two so the flow sludge doesn't have to go through the rads to the return cock, or vice versa. But I had been/am flushing with...

Thankyou PrenticeBoy. I will be covering it so finish is not that crucial. I would like to put down 25mm of Celotex followed by 2x9mm OSB. Also, when I said concrete I rather meant a cement-sand mix. I've seen this referred to as screed and dry mix both here and in Barry's Vol1. More...

Hi, I have old tiles on my concrete which can't be scraped up, a lifter would sooner dig up the concrete. On the wood floor abutting this the previous owner has put hardboard underneath the laminate finish to get a level finish. This has since degraded/rotted. The perimeter of concrete...
