either the h/w flow switch or diaphram reqs replacement or the secondary heat ex or (calorifier) is blocked and prevents the heat from leaving the biler to hget to he taps- the heat starts ok but backs up to the boiler very quickly causing it to shut down

SOURCE: Shower goes hot and cold

If you are having trouble only at the one fixture (shower), and no where else, the problem is most likely in the shower valve...which either needs new cartridges, or a complete replacement.
hope this helps

SOURCE: hi,i have a vaillant turbomax

Which turbomax, as there a two different models. The more modern one, with the brass CPL diverter valve, located at the front left of the boiler, was very prone sticking & jamming, this would restrict flow through the hot water circuit in the boiler, and cause cycling. Vaillant actually modified the diverter. You can identify, if it is the old type, as there is a very small hole in the middle of the diverter on the old ones, probable no more than 1mm-2mm wide. The modfied one, is much bigger approx 5mm wide. If old type, replace as this usally sorts the problem

The hot and cold are reversed on our single handle shower (no tub faucet -- shower only)


Hot on left.
Cold on right.
Some single handle faucets have bleed-over where both hot and cold enter mixing valve each time handle is turned on, even when faucet calls for just cold or just hot.
Otherwise maybe a do-it-yourself plumber got pipes backwards... or maybe the tub used to be on other side of wall, and tub was moved during remodeling but pipes were not changed.

To fix problem:
First of all, turn off shower faucet. Turn on Hot at sink and put ear against shower faucet listening for sound of water flowing through the mixing valve.
If mixing valve is working fine, you need to open wall and investigate more.
For example if you have access door, reach in and feel which pipe is hot.
Pipes might need to be reversed if problem comes up in home inspection, otherwise the problem will not harm anything.

My Bristan Meridian Show start ok with hot water then after a few minutes the water runs cold. Even if you try and increase the temp it still remains cold. You can switch of the shower and start again...


It sounds like 1 of 2 things to me. I will start wit hot water heater. The first test for the water heater is to have someone run the hot water while you hold the hot and cold pipes and see if the water is coming out of the water heater cold when the shower goes cold. Of the water heater is cold coming out then the problem is in the heater. ether a lower element is bad or the dip tube is broken at the top of the tank. if the hot water heater continues to put out hot water when the shower goes cold then it has to be the mixing valve for the hot and cold mix at the shower and that valve will have to be repaired or replaced. hope this gives you a good start. let me know if I can help further.

Code 13 help... Everytime I go to use the shower (a mixing system of hot and cold) Code 13-- Code 12 the system shuts down. If I just use hot or cold I am fine-- Any one?


if cold supply to boiler and shower are off the same feed this could be your problem as the boiler governs flow of hot water best of luck

Mixer shower connected to combi boiler running hot and cold and also not much pressure


Mixing valves usually have a diaphragm inside that keeps the hot and cold separate. If the diaphragm is old it may be allowing the hot and cold to mix improperly at the back of the valve. This is similar to a cross connection (a hot water line tied into a cold line) in your plumbing. Cross connections interfere with the performance of Combination Boilers and Tankless Water heaters due to their having no water storage or a very small buffer tank. The brand of the valve will help as each one is different in their mechanical design. If this is the problem you or a licensed plumber can replace the cartridge in the valve. Refer to your valve's owner's manual for part numbers.

Installing a Mixer Shower from a Combi Boiler.


hi there, your boiler will perfectly match the mira excel ( a great choice i might add) a 24cdi will give about 9.8 litres a minute flow rate hot water.
The mira excel is suitable for any plumbing set up and there installation instruction are very well laid out & their helpline is fantastic.
The hot water will fluctuate accordingly to the time of year as the cold water temp coming into the property will vary. but the boiler will modulate to compensate.So in brief in the summer you will notice it hotter than you would in the winter, this has nothing to do with the boiler just the incoming temp of the cold water.
