Mains fed electric shower

DEVEREUX

Hey,

I fitted a mains fed electric shower but getting no heat from it at all. I've been onto the supplier and they are sending a service guy out tomorrow.

In the meantime I've had a couple of calls warning me that if it is mains pressure issue I will be charged for the call out and there will be nothing they can do.

It was a straight swap from an old (15yrs) to the newest model (same brand).

I know it's not a pressure issue as the last shower worked perfect for all those years?

For my own education....if someone could tell me why would say half mains pressure affect the units ability to heat water rather than just giving poor flow with at least some heat??

What brand and model did you have before and what one did you replace it with

Electric showers work by directing flowing water over heating elements which heat the water as it flows through. If the water is flowing too fast, the elements won't have time to heat the water (you will have noticed that increasing the temp of the water results in lower flow of water from the shower head. Tempurature control is accomplished by increasing or decreasing the flow of water through the element.) Mains pressure going into the shower would be too fast for the element to heat the water. It could also damage the pump in the shower. Electric showers should be gravity fed from the storage tank, so that it's in-built pump can force the water through.

Is your shower connected to the mains, or to the storage tank? As for the previous shower working, I wouldn't necessarily read much into that. Newer showers have different power requirements and plumbing to meet Energy rating standards. The old shower probably just throw a huge amount of power into the element. Newer showers might not be as powerful, and use new fangled internal plumbing to heat water to the same temp but at a lower power.

What did the service engineer say?

Might help somebody like you looking for the same answer in the future.

Sorry I did intend to update but slipped my mind.

It turns out that the council had cut into hydradare couple of weeks earlier and this had affected the pressure slightly and as a result the new shower didn't work.

These guys had shown up 5 weeks ago with their con-saw and cut a square in ground around the stopcock, nipped the mains and fecked off for 4 weeks. I had noticed some water in street coming from these cuts but it never clicked in my head that it was related to the shower not working. :rolleyes:

After numerous calls and a harsh letter to repair the leak they showed up last Saturday morning and fixed the leak and also proceded to butcher the path which is now a trip hazard for my aged in-laws :mad:

But the shower works........ minus the service call out fee.
