Lukewarm water in bath and showers

apollo9

I need some help please. The hot water for the showers and bath is run off a separate pump from the main tank. I think because they are mixer taps.

We get plenty of hot water from the tank in all the other taps.

The pump for the showers has a cold and hot feed. The outlet pipes are cold and hot respectively. So what I can’t understand is that why isn’t the water in the showers hot? The pump makes a noise when the taps are turned on so I am guessing it works.

Just an experiment I have turned down the cold feed into the showers as both the outlet pipes from the shower pump have taps.

What else can I try?

Thanks

Is this a new, sudden problem, has anything changed? How many years have you had this set-up?

What happened when you turned off the cold feed to the shower? All the water to the shower should then be coming direct from the boiler so should have been hot.

Does the bath tap come through the same pump and does the hot there work correctly?

Thanks, I was thinking of trying that but was worried that turning off the cold feed would effect the pump. Will give it ago.

The bath and shower (2 separate bathrooms) both hav the same problem.

What happens if you put the tap fully to hot, is the flow still strong enough to operate the pump?

Yep flow is ok. Something weird is going on when they mix. I have turned the cold outflow down to about a 1/4 so will see how the kids react when they go for their showers.

It was fine this morning but then First thing it usually is.

Is it a mixer lever type tap? Sorry this seems really obvious but just turn it so more hot water comes out. I have the same setup well kind of hot water is pumped from cylinder to mixer shower valve and cold is mains. Pumps are quite difficult to balance the temp correctly. Start the shower with the hot fully open then adjust slightly with cold till you get your desired temp it won't damage the pump only having hot running that's how they are designed.

Ok thanks. I will switch off the cold supply from the pump and see how we get on. I think the other problem is that the tank simply is not big enough now with the kids much older
