Flow problem with electric shower

[Ed Addis]

Could be your water pressure

The temperature is determined by the flow rate - if the water pressure was too low, it wouldn't be possible to get the temperature down to a usable level.

Hi - my suggested process is - put the shower on the coldest setting it operates review the max flow rate you can get. If that flow rate is too low then perhaps it can be increased with descaling of the unit or the head. Once the cold shower rate is where it should be then you can review the flow rate at higher temp settings. If the flow rate drops significantly, the unit may need servicing. The kW difference you're looking at is not that great and both are powerful heaters when working correctly.

Its an electric shower. The design is flawed. Either get a non electric version, have a bath (in front of the fire) or towel wash etc

if the water pressure is too low,the heater will cut out giving you a cold shower. we have that problem. every time someone turns on a tap or flushes the bog, the shower goes cold.

Another little known and annoying fact,in a lot of areas,the water authority now employ a "pressure reduction" policy,between say 11.30pm and 5.30am,which affects operation of flow sensitive items.

It is popular in Australia,and reduces energy costs and leakage,during low use hours.

Expect the first three people you ask,at your water company,to be obstructive and non-committal

The problem arrives,when your device is set-up and functioning,by your plumber,during full service pressure...they seem reluctant to return during the hours mentioned,for a re-test

Thanks!

Our pressure is poor even at best. Fortunately we rarely use showers at the times you mention.

Surely the flow will always drop significantly when the temperature is turned up? Temperature is entirely dependent on flow.

Maybe ditch the electric shower and get a hot tank etc installed with a thermostatic head / pump installed - far better IMHO

See my OP - no other setups being considered at the moment.

See my response - its only an idea

Thinking outside the box

it's not called a box now, murdoch, down in posh cheltenham it's called a shower cubicle.
