Luke warm water supply from new thermostatic shower
Anonymous user 15 March 2024 - 2.50 PM
We’ve recently had a new shower fitted - it’s a thermostatic mixer with two outlets, one rigid riser and a handheld shower. The water pressure is fine but it just doesn’t change temperature from luke warm regardless of how high or low we set it. We have an old standard boiler with a tank in loft and cylinder in airing cupboard. Could it be because we have a gravity fed system? I just want to be a bit in the know for when our nice but slightly grumpy plumber arrives :)

The shower valve must be compatible with the high pressure cold and low pressure hot water. Some valves are only suitable for high pressure and cannot regulate the correct balance of hot and cold water. Alternatively you may just have a slight blockage in the hot water inlet filter where it connects to the valve!

If the hot and cold are both gravity fed the shower should balance ok but if the cold is main pressure and the hot is gravity it won’t blend so always run cool.

Agree with both of the above answerers.
It is possible that the thermotic cartridge to the shower, will require replacing, as possibly on its way out, dependant on shower age etc.

Check that the vent pipe in the loft is not submerged in the storage tank as this would suck in cold water when the hot taps are tuned on making the water like warm
