Shower question
 

We had a Mira electric shower fitted a bit ago but due to circumstances have only just started using it. Basically as soon as the heater elements kick in the flow drops dramatically. I'd be very grateful if anyone with an electric shower could measure how much water theirs puts out at max flow rate at a decent hot temperature. Mira are coming out to look at it but I would like some ammo in case the engineer tries to fob me off.

just for info, these are the figures for mine

on max flow setting

COLD i.e. no heat 12+litres/minute( this proves that there is plenty of water pressure at the shower)
WARM (Anything from number 2 upwards) 3 litres/min

Cheers!

2-3 litres is not a lot. I have an Aquastream power shower which damn near blows me out of the bath both on hot and cold. Water pressure was a problem initially but I had my water tank moved and a second one installed on the top of it, it's fine now. I don't know exactly how much water per minute comes out of mine, but it's a good flow rate..:D

Re: Shower question
 

This isn't a power shower but yes, 2-3 isn't a lot, its like someone sprinkling your back out of a handheld watering can. Hence teh call to get them to fix it. I would just like to be able to turn round and say in a sample of 20 houses with eleccy showers the average flow is 7 litres/min. Make mine do that.

Posted as me this time.

I think it is an 8kw or 9kw shower, it is quite a few years old and was in the house when we moved in.
At setting 9, which is pretty damn hot it took 45.72 seconds to fill a 3 litre jug. so 1 litre took 45.72 / 3 = 15.24 secs.

Therefore 60 / 15.24 = 3.93 litres/minute

Re: Shower question
 

Did you take your clothes off to measure it?

Re: Shower question
 

We are a forgiving lot not to worry.

The question is Rindy will you?

Thanks to Neil for actually helping, come on you lot!

Re: Shower question
 

Just back, dripping wet.

Mine measuered a bit more than Neils.:)

Re: Shower question
 

We haven't got the best water pressure so when I bought ours I bought the highest wattage available which was a Heatre sadia 9kw (might be available higher now)
On the coldest setting I measured approx 8¾ litres/min and set to a hot but usable temp it measured approx 6¼ litres/min
Hope this helps

Re: Shower question
 

Shhhh don't say that Ian. The last thing we want is Rindy getting undressed in the Stag to measure it.

Re: Shower question
 

Is there a power level aswell as a flow rate on it, if the power level makes no difference then its the second element not working. also did you make sure you flushed the pipework out before you fitted the shower?
If its faulty the engineer wont fob you off, he'll just repair it, the problem is if you've done the damage or there is no fault, which i understand is why your here asking us and that means your not 100% certain its faulty. If your water pressure is ok, and you cant get a decent flow of water at a warm temperature I'd say its faulty, you can see from above, most get too hot and still have a good flow. The only ones that struggle are the 7KW ones. You can get 13kw and higher now. Mines 8.5kw. Showers work by heating the water in a mini hot water cylinder, to do that they have to slow the water down, the hotter you put it the slower it will get, most have two power levels, the first kicks in when the shower is switched on, the second when you turn it on, the first will only be luke warm in this weather even on hot

Re: Shower question
 

just under 4 litres on an old 8.5kw triton

Re: Shower question
 

We had a shower once where the water pressure dropped as the temperature went up and it was due to the fact that the water pressure dropping was the method for increasing the temperature. More water going through and same amount of heat heating it meant it didn't get as hot as not so much water did. If you see what I mean. It was a crummy shower. It was also a Mira.

Re: Shower question
 

Thats how electric showers heat the water mr wisp, if its crumby its cos its low powered

Re: Shower question
 

Could the problem be due to Lime scale in your pipes.Not allowing enough water to flow through ??????? Suffer a lot from that over here.De limescale the pipes and shower head about every 3 months and its brill

Re: Shower question
 

I dont think thats he's problem as he is getting 12L/min on cold setting so the water is flowing OK

Re: Shower question
 

Thanks everyone for info up to now.

There is no problem with the supply as I mentioned on cold I get 12 litres/min. It is as soon as the heating element kicks in that the pressure drops dramatically. The flow it then constant whether its on number 2 or number 9. There are 3 flow settings on it and the difference is negligable on any setting.
Teh engineer is coming next week so we'll see what he says

Re: Shower question
 

are you sure its a normal electric shower? whispy, the only way to adjust temperature would be to adjust the heating element levels or to adjust the flow.
AS for the above it sounds like a faulty flow control valve, I'll check in a bit how it works, im on a break atm. i cant remember of the top of my head, but it sounds like a fault I had on one.

Re: Shower question
 

Bloke is coming on Friday :)

We'll see what he says

Re: Shower question
 

Re: Shower question
 

It's normal, it's just that its a good one whispy.

Re: Shower question
 

It's Friday Ian. Is it fixed now?

Re: Shower question
 

What an Absolute joker!!!

Turned up,

I put the shower on explaining that it is only producing 3 litres/min

"Oh no, thats fine that is, thats at least 4 and a half litres" he says looking at the trickle coming out the shower head.

"Just how can you say that? " I asked. explaining I had measured it 4 times with a jug the other day.

"Nowt wrong with it. You lot all expect power showers" says he.

I go and get a jug (1litre to brim) and something to time with.

He starts filing the jug up and when its 3/4 full empties it and says "1 litre!"

I point out it was nowhere near a litre and he has a hissy fit. I then meaure a full minute flow filling the jug to the top. 3 litres takes 63 seconds.

He says "No, that was 4, you were spilling loads" despite the fact I wasn't.

At this point I just said "If you aren't going to do anything you may as well leave, I'll ring Mira back and get them to send someone who will"

He goes off proper style. starts grabbing the book and showing me this graph with temp/flow shouting look, 35 degrees gives 3 litres flow, only I did Maths at Uni and I know how to read a graph and at 35 degrees it clearly shows 4 litres.

At this point I asked him to leave. He asked me to sign his work sheet and I said yes, I started to write that I wasn't happy and the job was not complete to my satisfaction and he rips the paper out my hands and starts ranting again!

At this point I opened the door and he went out slamming it as he went!

Anyway, I've rung Mira back and said I want someone else as I was disgusted with him. and they said they will try and send the area manager.

Next update will be posted!

Re: Shower question
 

whoah you go for it Ian. All that straight after your op! I'm proud of you :D

Re: Shower question
 

It is so annoying when people try to assure you there are right when infact they clearly are not!! well said.

Re: Shower question
 

wow he wasn't planning on meeting you then was he Ian?..........you remind me of someone.......think I married him!!!

Nice to have you back btw........hope your on the mend.

Re: Shower question
 

If there is one thing I hate it is people trying to take the pee. He had no intent on doing anything and was obviously paid by the job so quicker in/out the better for him. I don't think he expected someone who had made sure they had the facts to hand and weren't going to be led a merry dance.

Oh no!!!! being compared to NEIL of all blokes :):):):):):):)

Re: Shower question
 

I think I watched a video similar to the scene just posted, except that it was in German.;)

Well done for sending the plonker packing.:)

Re: Shower question
 

Thats rich coming from you. Remember when I had a clutch replaced by a free collection and delivery firm that tried to charge you £3 for the petrol he had to put in the car because it was on the red light when the clutch went :D

Re: Shower question
 

I had to go and buy a new golden shower pipe the other evening, as Rhonda got in the shower it split.

Re: Shower question
 

Bet shes really greatfull for you doing that.
Not impressed with mira at all, that sound terrible. where are mira based ?

Re: Shower question
 

after sales service lol that went years ago, they cant even give you during sales service nowdays. we're having a new bathroom and kitchen fitted, typical council cowboys, one of fhm kitchens sub contractors have scratched the triple hallogen light fitting but they deny they've done it. 35 quid it cost me, and now it's ruined, they say how could they have done it. The fact that they ripped the old kitchen out with a hammer and crow bar seem irelevant to them, they say I've done it, I took a piece of wood and stood there scratchin hell out of my own light fitting so I could claim a new one. A new one that wont match the three single spots, ye right, so I vote them cowboys of the week, closely followed by north warwickshire borough council, who do sod all, I don't know why they don't close the offices altogether and save us some cash
