Only cold water coming from Grohtherm wireless 36023


There are multiple possibilities:
- the power to the main control could be off (seems unlikely if you can turn the water flow on and off)
- the thermal element that heats the water could be burned out (may not be a problem if this is only a mixer unit and relies on external hot water supply)
- there could be a problem with the solenoid that opens to allow hot water to flow through the unit
- there could be either no hot water getting to the unit or blockage so that hot water will not flow through to the mixer

Start by making sure there is power. Then you may need to disconnect the hot water supply (after turning it off at the source) and then check to see that hot water will flow. If you get hot water to the unit then there is something internal keeping the hot water from mixing with the cold.

Hansgrohe Ecostat (with part 94282000 thermostat). Shower runs fine for a few minutes then boiler shuts down and shower runs goes cold. Boiler starts up again after 30 seconds and runs fine for a few...


Check the 94282000 cartridge for debris on the filters. If your boiler requires a certain flow rate to come on, then you must get enough flow through the cartridge to make that happen. Also, if your boiler is producing very hot water, the cartridge will self regulate and reduce the hot flow accordingly. try lowering the output temperature of the boiler to resolve that possibility.

My shower is run off a combi boiler and recently started to go cold for a couple of seconds every few minutes and nobody is running water elsware in the house.


Check the hot water flow at the shower - if it's as good as other taps the boiler diverter valve is suspect. Replace either the complete valve or the internal rubber diaphragm, depending on the boiler make

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.

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

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.

Kindly
