Hi All,
I had a Vaillant ecoMAX installed around 5 years ago and it has been great... up until just before Christmas. Now the hot water temperature drops after about 30-60 seconds and largely remains cold. Cutting the flow to about a 1/4 can heat it up again. This happens on the sink taps, bathroom taps and mixer shower.
There are no errors coming up on the boiler lcd and I can see the tap icon. Pressure seems fine.
I initially thought (or rather hoped) that it was just the outside temperature causing the boiler to struggle, but it was slightly over spec'd for the house to begin with and sas I said previously, has been great until now.
Any idea?
Cheers
Dai
