The flow of hot water from the kitchen tap isn't fantastic can i put a bath shower mixer on to the system? What would i need if anything to increase the flow of hot water.

The puma has a filter in the cold water inlet, cleaning or replacing this will increase the flow rate.

No reason why a thermostatic mixer shower wouldn't work with a puma boiler.

thanks i'll look at the filter and clear. does it have to be thermostatic mixer shower as i'm looking to put on bath taps with a shower attachment. Kind regards Dan

Yes it should be a thermostatic mixer shower, for safety reasons.

I have just fitted s Mira Excel Bath Shower Thermostatic Mixer Shower in my house, and I would recommend it. It fits onto the bath like a mixer tap then a shower attachment comes off the top. It cost £360, well worth it.
