QUESTION FOR PLUMBERS - Can I get any Shower mixer taps re combi boiler?

Question

I have a Combi Boiler that takes water direct from mains (no water tank).

I want to put a shower over my bath by changing existing bath taps to shower bath mixer taps. My questions:

1) Is my water pressure likely to be same from both hot and cold taps for the new mixer taps?

2) Will a bath shower mixer tap work without having to have the thermostatic control (re water pressure and temperature)?

Grateful for any advice - thank you.

Answer 1

Im not a plumber - but I have a combi boiler - no water tank - and have mixer taps on my shower.

I used to have an electric shower with temp controls that required a pump for water pressure - but this new showers not using a pump or anything else and works fine.

**ed** actually, yeah mines hard to balance too - its quite fiddlely to get the right temp on it..

Answer 2

the water pressure will be similar and within the range allowed by the mixer manufacturer

get a thermostatic mixer which keeps the temperature stable despite changes in the hot or cold water pressure/flow. much more pleasant  

Answer 3

Bath shower mixers work fine with combis. Thermostatic mixers are expensive to buy and install and need regular maintenance in hard waster areas. I would choose a tap based mixer every time. The adjustment to get the right temperature is easy to do and you do the usual number of turns automatically after a while.

Answer 4

No problem at all.

It will work well with a standard mixer, but obviously it will be far more controllable with a thermostatic unit.

You can get a thermostatically controlled bath/shower mixer that is easy to fit, and provides a very powerful shower at very nearly mains pressure.

Answer 5

i have a combi boiler and mixer taps to a shower, but it isnt a thermostatic one and is really hard to balance. the hot pressure is low so that may be the problem. My main shower is electric, so no issues there.
