Question about Water Heaters
Junkers gas water heater model number wrd11- 2 the flame is burning very orange rather than blue, causing black soot on wall of villa
You must get more air to water heater, and check venting .... immediate CO poison danger.
Call qualified plumber immediately.... because deadly carbon monoxide is not being vented properly.

Yes that is going to be the contoll valve on that heater. You can probley fix it very easy with the right part. You will need to locate a plumbing supply over there in the UK. Give them the make and model number and tell them you need a unitroll gas valve for it.

This problem sounds as if gas pressure to the burner is to low, check mnfr's plate on heater for the correct burner manifold pressure, you will need a manometer or a guage that measures inches of water column, set the pressure correctly and the burner should stay lit.

The thermocouple sensor may not be in the best position to sense that the pilot is lit.
Adjust the thermocouple mount or simply bend the thermocouple "wire" so that the pilot flame is touching the tip.

Tips for a great answer:
You need to get a Plumber or Appliance Tech to come out immediately and check the fuel to air ratio. You are not burning your fuel at the proper mixture. A blue flame is good, yellow-orange is bad.
Normally this is because the burner area is dirty or the pressure regulator may be set too high/low. The black marks are a sure sign that your ratio is too rich and it's just going to build up more soot and become unhealthy and dangerous.
