My shower goes hot then cold then hot all the time - is it a boiler pressure issue? I have a Vokera combi?

Answer 1

if you have a combi there are no elements,,
are you running anything else like a washing machine or dishwasher,,if you are this would take away water for some moments and make you shower run hot and cold,, is the water pressure in the boiler up to the required pressure,, there is a small gauge that shows you what the pressure is this must be in the black zone,,this is done by ,,,
turning off the boiler,and opening the cold water inlet valve until the pressure is up to the required psi, then turn the boiler on again,
then make sure that the radiators have been bled,, that there is no air in the system,, failing all of this call on a qualified heating engineer

Answer 2

If the other taps are ok then the problem lies with the shower. Try running another hot tap just slow so as to increase the flow rate through the boiler, if the shower is OK like this then clean the head some of the holes will be blocked. If this doesn't fix it then you will need to get a engineer in to carry out some diagnostic tests to determine if its the PCB, gas valve modulator of just a water sensor. Had the same problem with a Vokera before Xmas that was the PCB.

Ur bathe water source is tied in through 1 million line. What I meant is they splice the nice and cozy water line to both bathe and similar with the chilly water line. really, ur sharing an similar water source. which means this glitch is worry-free on all domicile and u ought to artwork it out so in common words a million human being use a million bathe to stay away from this difficulty. also, examine the water rigidity on the line. the classic rigidity should be set at 65lbs. If that is below that, like 45lbs or a lot less. This fluccuation difficulty is extra worry-free. i does no longer reccomend on the thanks to revive / modify the rigidity regulater as i'm prevented to inform u through code. in common words advice i am going to tell u is purchase a rigidity gauge or and hook it as a lot as a water hose tap and skim the rigidity. ensure the water is change on after u tighten the relationship. If water sips out really, its ok. All u pick to understand is what the water rigidity is. the city needs a qualfied human being to do the adjustment. (like a plumber) . I have a feeling the perfect human being did not adjusted to the right rigidity.

Answer 4

yes it is a problem with the boiler and generally connected with the switching arrangement that cuts out the central heating when you take a shower. It is not too difficult to fix but you should use a CORGI man

Answer 5

are you shareing water with anyone else at the time? i something like that on this old house or diy and they put a thing in the wall that equaled out the pressure have you put a insulation blanket arround your heater or does one fit or is that an option you could also put that foam stuff arround the pipes or put your shower head in vinagar but none of these options may be part of your problem it would just make it more energy saving you can also git an energy saving shower head

Answer 6

Reduce thermostat temperature at 65 degree, as you have set too high. It boils and becomes steam inside. While taking bath hot water comes out mixed with steam so you feel hot and cold water consecutively.

Answer 7

It might just be that you've burnt out a heating element. If you live by yourself and no one else will be using the water while you're out, turn the water off and take your heating elements to a local hardware store. They should be able to tell you whether they're functioning or not. Or, you can call a specialist.

Answer 8

more than likely a dicky thermostat
