Hi all, visited the site a few times over the years for useful tips but now I have a query of my own.
We have a Glow Worm hideaway 70B which heats the cylinder in the loft via gravity. The central heating is operated via a single pump which a replaced the day after we moved in 9 months ago as it had burned out due to dripping pipe from the previous owners washing machine removal.
There's no wiring to a cylinder thermostat as far as I can see.
I drained down the hot and cold water to replace the service valves that feed the shower with full bore models to eak out a little more flow/pressure yesterday.
After refilling the system it took around 90 minutes to heat the water.
I have no idea if this is normal or not other than the previous system we had at the last house which took about 30 minutes to heat the same size cylinder.
The supply into the cylinder was nice and hot and coming out was cooler but still reasonably hot.
So - a few questions regarding my setup;
1. Is that sort or recharge time "normal" assuming the details are enough for a rough guess of expected performance?
2. If I pump the hot water up instead, does that improve performance?
3. I'm assuming the coil in the cylinder is probably just a small one as we aren't in a hard water area so I don't think it's scale - does that sound right? It's a grade 4 cylinder
4. I may replace either with a fast recharge cylinder, how much better are these over a normal one? are there better versions e.g. stainless / upgraded insulation available?
5. I may replace with a thermal store and get the flow I want for the shower but money as always is limited. Any suggestions on which offer good/better value?
6. Given there's no current cylinder thermostat, I'm guessing the boiler has one built in that works on the return feed?
I should probably stop typing now!
Thanks in advance.
