Actually, it didn’t ever get fixed. I’ve just been putting up with showers ending early, going tepid. I rush when using it, but still don’t get enough hot water. I thought I’m probably going to have to buy a new one. The service company ran out of ideas after checking the obvious stuff and sent...

Ok I ran all the tests again. Firstly, I got a bigger container to fill and more accurate timing. 12 litres took 31 seconds so 23Lpm I ran the hot tap until is was look warm then it took the boiler 5m 35s to heat to ‘4’ on the stat Turned the stat to ‘6’ (max) and the boiler fired for a...

Hi. The burner did run when the HW stat was turned up *(and I did let it run for a while until it stopped), but I didn’t note how long that was for. I can retest that and also the second routine you mention.

Thanks, OH. OK turned the hot water stat to just under max (6) and ran the tap full open. There was a slight difference in time before it lost heat, but only 20-30 secs max, which is probably within the margin of error. I waited until the burner had stopped after turning the stat up to max...

The boiler was here when we arrived in 2012 There is a combimate Central heating appears to work fine A rough check with a jug and a digital stop watch is 1l/4s which is about 15l/min Yes, at a rate of 1l/15s or 4l/min it was still piping hot at 5minutes Both the hot water and the heating dials...

So is there a sense in which the hot water in the heatstore is ‘used up’ even though it’s not being drawn directly from there? I Now understand it go to the heat exchanger To heat up incoming cold water

I had someone look at it and they said since the boiler fired up fine and put out very hot water they thought that there wasn’t a problem with it, but they didn’t leave the tap running until it went cold as I had

Hi. Thanks for the reply and the correction on how it works The hot water flow hasn’t decreased and is much like the cold. It’s not a new problem in that we removed a bath as there was never enough hot water to make it usable (we used an electric shower instead) In August we removed the bath...

Hi, would be extremely grateful for any pointers on this problem The full name of the boiler is the Worcester Greenstar Heatslave 18/25 Oil combi. The boiler has a 69L heatbank. We leave the water permanently set to on. When I run the hot tap nearest the boiler i get hot water as expected...

@oilhead thanks for answering there and here :) As I responded there, it made no difference what rate I ran the tap at. When run full tilt, I got 60-odd litres of hot water then it went cold. The next day when I ran the tap at half-rate I got 60-odd litres of hot water then it went cold. It was...

Thanks Jim, John I’m not actually looking to run baths, was just doing that to test what volume of hot water I’d get before it ran cold. Approx 60 litres, or a heat bank’s worth. What I want to do is get rid of the electric shower and replace it with a thermostatic one In the end I just pulled...

@ericmark I’m not sure how you tell definitively. Some say they are combi, others not. I’ve been told they have an internal tank/store/heat bank while others have told me they do not. Someone has to be right unless there are lots of different versions of the Worcester Greenstar Heatslave (i) oil...

Hi, thanks for the reply. Another person has told me since it’s a combi boiler I should get hot water for as long as I’m drawing it, not just that in the tank.

Hi, my first post here, but I sense not my last I currently own this boiler, but up until now have been using an electric shower. It’s pretty pathetic tbh and I’d like to convert to a thermostatic shower. I’ve just run a bath to see how much hot water I’m getting. The answer is I get about 8cm...
