Ok, as a temp measure, I'll take it apart clean/replace as neccessary (I think I have a spare one anyway) and see how I get on. I think I'll look into replacing the tanks with just larger capacity versions at some point. I'm going off the idea of an unvented cylinder!
House is probably 1970's. Cheaply built 2 bed terrace on a housing estate full of the same houses. Pipes are copper, I'm sure.
Flow at the downstairs kitchen tap (all on 15mm pipe) is 15.6 litres per minute. Pressure is 3.0 bar with no taps on. Drops by 1.5 bar when a tap is fully opened.

Thanks for your replies. I'm swaying that way I must admit.
Is there a way I can get the tanks to fill up quicker? At the moment they're filled by a floating valve but the flow is so slow it can't keep up at all. Any way I can get them to fill up quicker?
Obviously larger tanks...
One thing I did notice last night was all the manuals for unvented cylinders say they require 22mm mains water supply pipe, the mains water supply into my house (and into the main stop cock) is only 15mm. Is this going to cause a problem if I go for an unvented?
Absolutely. I'm very annoyed at our bathroom fitter. He recommended we have a digital shower and recommended the Mira pumped one. He then fitted it and didn't tell us that the current heads weren't balanced, and that neither tank was large enough.
Our boiler then packed up and we had a...
The shower says the cistern must be 230 litres to keep up with the maximum 16 litres per minute possible flow, so the cistern simply isn't large enough. The cold tank in the loft must only be about 75 litres or so.
I had it set in my mind that I would go for an unvented cylinder, but I'm not...
Got asked for this info on another forums so I copied it over here too...
It's a 2 bed house, one bathroom, 3 people.
Boiler is a Vailant ECOTEC Plus 41, open vent 15kw.
The heating is open vented, fed from a reservoir in the hot water cylinder. The hot water is open vented, fed from...
Hi,
I'll give you a brief rundown of our nightmare! We had a new bathroom fitted and the bathroom fitter recommended we get a digital power shower, so I bought a Mira Platinum pumped digital shower. He fitted it to our system, which consists of a regular boiler, cold water tank in the loft...
