Why does the water temperature change in the shower?
If your water temperature fluctuates, the pressure-balancing valve might be to blame. Your pressure-balancing valves open and close depending on your water flow in your plumbing system. This drop in pressure sends scalding hot or freezing cold water to your shower head.
Why does my combi boiler turn off when I take a shower?
If a combi boiler can’t manage all the hot water demands simultaneously, then it gives hot running water priority. Therefore, it may turn the radiators off temporarily, while someone draws water in the kitchen, runs a bath, or takes a shower.
What happens when you turn off the water in a boiler?
System and heat only boilers will continue to heat up the radiators, and you might even get a bit of hot water out of the cylinder, but that will dry up pretty quickly when there’s no pressure or new water entering the system. Unless you turn on a hot tap, the system will carry on running as if nothing has happened.
How is the pressure maintained in a boiler?
It draws hot water from the top and supplies pressurised cold water to the bottom, which is how pressure at the taps is maintained.
Why does my shower have a hot and cold boiler?
That’s because regular gas boilers have electric immersion heaters in the storage cylinder, meaning a hot / cold shower should be a thing of the past. As a result, you have a temporary solution to your needs, although this comes at a higher energy cost so get yourself back on main gas soon as you can!

Where does the potable water in a shower come from?
The shower will take potable water from the IST (indirect storage tank) that is stored and already hot. If the aquastat (a water, not air-sensing thermostat you set to whatever it takes to get all the hot water you need) will tell the boiler the IST is running low on water temps, and to “turn on” to replentish the waning water temp situation.
How big of a boiler do you need for two showers?
If you have two showers going at once, you need double the boiler/burner – as well as a tankless coil that can utilize all those BTU’s – a 6 GPM coil (way larger than typically installed in all but a mansion-like setup). 3.
What happens if you turn off the water supply but leave the boiler on?
Observe it for a few weeks after you turn it off make sure the pressure is staying the same. If the system doesn’t leak leave it off. That way if it does leak the only water you leak is what’s in the system. However the boiler will dry fire if it does happen to leak, not good. a LWCO is pertinent to have for safety.
