Just had the en-suite re-kitted out.
Previous shower was gravity fed, scalding hot water.
Replace with a Salamander RSP50, all plumbed according to the Salamander spec.
Hot water now only luke warm, any ideas please?
-
What type of shower?
Thermostatic bar, basic mixer....etc etc

Thermostatic bar.
Hot turned upto max.
Water is scalding out of sink taps.
-
What solution was used for the hot outlet on the tank?

Essex valve, loft mounted pump.
-
So, the pump is above water tank?
The RSP50 is for Positive head instals only, it wont do negative head setups
-
Salamander site hints that it can be done but, you need an anti-gravity loop at the tank outlet and air vents at the highest points to allow bleeding
-
Just checked, they haven't fitted an anti gravity loop!
I'll get them back!
Thanks Mark :y

Did they fit the bleed points in the loft?
If so then bleed the system, set the bar valve to max hot (sometimes you have to pop the hot adjustment nob off to do this as there is a built in stop) and run the system to purge any air.

I'll query that with them, when they return.
Would the anti-gravity loop make much difference?
-
Its main purprose is to stop hot water gravitating up to the pump when its not running but it also reduces the potential for air to get into the pump system.
I suspect you have air in the system but, the install does not meet the requirements of the pump supplier so a further issue is present.
Also, the feed pipes should be in 22mm pipe (and idealy 22m to as close as possible to the valve also)
Sounds like you have fallen foul of the 'plumber knows best' syndrome ;D
-
Another thing worth mentioning is that sometimes those style of mixer need calibrating as they are installed - basically, as Mark hints at, the knob needs to be correctly positioned on the valve shaft, so that the stops that limit travel cover the correct temperature range. It could simply be that you can't turn it far enough to get a decent temperature, but get them back to sort out the rest of it anyway. :y
-
Also check the hot and cold supplies go to the hot and cold inlet of the mixer, they are specific.
Sounds a bit daft but I did this once by mistake and the mixer would only run warm, took me aaaages to figure out

Checked the bleed valves in the loft, no air.
Would the gravity loop make all that much difference?

It means the manufacturer will honour the guarantee if there is an issue. :y
Did they not check the operation after it was fitted?
-
Yes they did, finished it yesterday, seemed ok, it was only when we showered this morning that we noticed the problem.
-
I recently fitted a new shower with a thermostatic mixer bar, where the hot water came from a combi boiler. It was fine at first but gradually the water got cooler and cooler. :(
Cut a long story short, the thermostat in the mixer was faulty and a new one sorted the problem. :) The temperature knob was very stiff and once the new thermostat was fitted it moved a lot easier. :y
-
It's probably a few decades since AA last saw a stiff knob
-
The thermostatic showers we put in hospitals are limited to 37degC.
The chances are that any quality thermostatic shower will leave the factory limited to the same temperature. 37 degrees was chosen so as not to cause any harm even after prolonged exposure.
If you want to step out of the shower looking like a lobster you will have to increase the temperature by moving the temperature stop.

Anti gravity loop fitted, thermostatic valve adjusted = HOT SHOWERS :y

At least I haven't reached that stage yet, you senile old sod ;)

Excellent, these shower pump design engineers are clever people with good instructions :y

One day maybe they'll invent a plumber who is both able and can be bothered to read them. ::)
.. Unlike like the one who fitted my parents' cast stone shower tray with a flimsy bit of chipboard underneath, despite the big sticker on the wrapping stating that it needs a minimum 18mm marine ply with a layer of mortar on top. ::) I doubt he got the replacement under warranty when the inevitable happened and he was back to do the job properly. ::)
