lights dimming when shower used

[shaunsparks]

Hi,we have got a 8.5 kw triton shower and its fed on its own circuit,but when its been used and we turn it off the bathroom lights flicker dim then go back to normal.Is this normal practice or does it need investigating further ,cheers.

it is normal. the shower uses loads of power so the lights dim

thanx for that ,the water still goes hot or cold when a tap as been turned on downstairs though ,cant have everything cheers

thats because you are depriving the shower of water, so what water it does get gets heated very hot, the overheat stat realises and turns heater off so it goes cold.

Dont worry it is normal

That's why some of them have thermostatic controls.

 

[breezer]

some, being the optimum word

 

[ban-all-sheds]

Agreed - "not very many" would be another way of putting it...

Can you not, with that type of shower, utilise a supply from loft tank .. if you have one ?

Ok, then deliver by pump, from a remote holding tank ...

No - you cannot supply an instant electric shower from a tank - must be from the main.
Disregard this.

I phoned a friend on the electric shower served by pump issue, he lives in a cottage serviced by spring water ... I have seen the cows in the fields above .. ooer! hi-tech filteration or not !!
No mains supply.
I am certain I saw an electric shower in his bathroom.
His response :- Triton T80si pumped supply from loft cold tank.
I searched it out :-

Damn, more searching required under 'Range'
Not easy to find info on this, usually tucked away in a few words under pumps among the shower adverts. Useful info I think.

My apologies - I had no idea.

Need a bl**dy big tank, or bl**dy short showers....

Hope it's got something more sophisticated than an emergency thermocouple to stop the can overheating when the water runs out...

Apparently shower has it's own large dedicated tank in the loft.
I recall the owner having a moan about the costly, strengthening work required for the loft based water supply tanks, and their twin pump feed with associated piping from a sunken garden resevoir ... All sounds a little expensive.
Some ex city dwellers just love the simplicity of country life ... Until the realities of the extent that home comforts can hit the bottom line in bank statement !!
