Hello
Bit of a strange one.
Our boiler (Viessman 35kW) provides our hot water. It starts off fine and hot but a few minutes later the water runs luke warm. When it's running luke warm it heats up to hot again temporarily when another hot tap is run but then quickly goes back to luke warm again.
When in the shower the water changes quickly from hot to luke warm.
Looking at the boiler when the hot is running it goes up to 70 plus deg then drops down to 40 ish.
Seems very strange - anyone any ideas?
Thanks
Alan
