Bathroom Fitting

Water pressure from combi to 2 showerheads

Anonymous user 03/03/2024 - 3.27 PM

Currently have a combi boiler and single shower with thermostatic mixer. Water pressure is fantastic and the water temperature in the boiler is set really low (1 /10). If I add a second shower and find the water pressure is low when both in use, can I increase the boiler water temperature ? Mains water supply is boosted with pump so surely I can mix in more high pressure cold ?

Are you a tradesperson and able to answer this question?

The combi boiler will not support both showers running at the same time

What it is important to understand in having a combi boiler is that the boiler need time to heat up the water that goes through it before coming to your tap. Most common error is to full open the hot water tap and pretend of having vey hot water straight away. That does not work. If the water that you require is too much (like when you full open a tap) the boiler has no time to heat the water. Try to increase boiler water up to 8 and see what's happen. Two showers open at the same time asking for hot water will dramatically bring down the water pressure. You said you have a pump. Let's try it. Increase hot water gauge to 8 and try whats happen with both working shower.

Combo boilers work best when only one Person is showering at once. If you want more than one bathroom you are best to add a megaflow tank and pressure bottle that way both bathrooms won’t loose pressure and heat when both being used.
