We have recently had a bathroom ripped out and replaced. We have gone for an Aqualisa shower and when our builder/plumber installed the shower it was really powerful even on the hot setting. The pressure was excellent and I was over the moon.
However over the last few days, the pressure on the hot water has decreased massively and I have no idea why.
We have a combi boiler (Worcester Bosch Greenstar CDI) that was installed a few months ago and even when it was serving our ancient non power shower prior to having the bathroom done, the pressure on the hot water was excellent.
Now I'm quite upset as we have a much more up to date shower, but in fact the pressure is worse.
But I cant work out why its changed as like I said when the shower was first installed (2 weeks ago) the pressure was excellent. What could have caused it to change?? We don't have any other water running at the same time. The only thing we have done in the past few days to do with the plumbing is install an American Fridge Freezer that has a water dispenser and we also bled a radiator as it was not heating up properly. But surely neither of these 2 things would effect the pressure of my shower?
Please someone can you help shed some light on why after 2 weeks of fab water pressure, it is suddenly turned rubbish??
Thanks so much in advance

When you say power shower, please elaborate.
Do you mean an electric shower?
You cannot atttach a pump to a combi boiler, so it cannot be a true "power shower".
Or, do you have the shower, without a pump fed directly from the combi ,that is the only way you can do it, this is not technically a power shower.
Has the pressure on your taps dropped also, or just the shower?0 -

Sorry I didn't mean to confuse. We now have the Aqualisa which is an electric shower.
Our shower previous to this was not electric. It was just a hose attached to the taps.
However the hot water pressure was actually better coming out of the old shower than it is coming out of the Aqualisa (albeit when it was first installed, it was excellent)
Am I making sense?
Oh and the pressure only seems to have dropped in the shower. The hot water round the rest of the house is fine0 -
if it helps at all, the other weird thing is that when the shower is set to hot and you press the button to turn it on, to start with the water is coming out really powerfully. Then as soon as the water heats up, you can visibly see the pressure decrease.0

The best set-up for a shower on a combi boiler is a shower directly fed from the combi with a mixer tap (with thermostatic valve).
You have actually taken a backwards step in my opinion.
An electric shower is always limited by their size in KWs. They can only heat so much water by so many degrees at a certain flow rate. The hotter the water needs to be, the slower the flow.
It is like having another mini combi boiler in your bathroom, but it just runs on electric and is no where near as powerful [as your actual combi] and more expensive to run.
Regarding your issue though:
Are you in a hard water area? Is there a filter on the feed pipe for the shower? there could be some debris suck which has reduced the flow.0 -
An electric shower won't be using your hot water system at all -so nothing to do with the combi boiler - if it has been set up with its own feed off of the cold water incomer (you presumably haven't got a cold water tank?) then there will/should be various pressure reducers/filters on the supply to the shower -sounds like the system is becoming blocked -when we had a similar problem, I stripped out the reducer to find bits of solder wedged in it!!0

Thank you very much for your reply. I'm a bit disappointed that I seem to have gone backwards :-( I know nothing about this sort of thing and was just recommended the Aqualisa showers. So does this mean that anyone with a combi boiler and electric shower, doesn't have a powerful shower? How many KWs does it need to be to be powerful?
The only thing that confuses me though is that the shower WAS really powerful when he installed it 2 weeks ago.
We are in a hard water area. Sorry I don't know how I would find out if there is a filter to the feed pipe. Where would this be? Also would this only effect the hot water as the pressure from the cold setting is incredibly powerful.0 -

Thank you for your reply. We don't have a cold water tank anymore. It was removed when they fitted the combi.
Where is the reducer found? I don't know what that is.
I don't have to destroy my newly fitted bathroom do I?0 -
