Due to the government puahin up rent prices my housing association
now have a surplus of cash and are replacing the boilers with new
ones. My old boiler was brilliant everytime they serviced it they said
how efficient it was.
I found this thread //www.diynot.com/diy/threads/new-vaillant-ecotec-plus-418-hot-water-not-hot-enough.233250/
and can see some of the ideas given but mine is slightly different.
You may want to get a flask and dandwiches for this.
Where to start? It was only fitted a couple of months ago and until
recently we had it on hot water only. The water didnt seem as hot as
before and also seemed to take longer to get hot water to the taps.
Just put it down to the temperature monitors being different.
I thought the pump in the airing cupboard seemed to be running a lot
longer than it used to also.
Then i switched it onto heating as well as hot water and things went really
badly. No heat unless you switch the hotwater off. So we can have one or
the other.
The pump runs for hours and hours after the water has heated. The engineer
said no its only 20 minutes and then muttered about the heating being on
and would not listen to me when i said the hot water heated for 20 minutes or
so and then went off and then back on again 2 minutes later which it then
repeats randomly. He said it depends on the efficiency etc. Our system is
very efficient and it didnt take hours to heat the water or for the boiler to
keep kicking in and out every few minutes with the old boiler.
He said its the electric valve that switches from water to heating and both
blamed it on the snapped indicator arm which was broken when it was
new but as its just an indicator and still visible it never caused any issues.
One day the heating didnt cut off at 18 degrees as set by the stat, it was
getting close to 25 degrees and the boiler was still heating. (set to heating
only).
They changed the tank temp sender and now they have changed the valve also
but it still doesnt work.
I currently have the hot water off and the heating on timed, and have to switch
the water on between the heating times.
Even this doesnt work properly....aghhhhh.
Heating switched off at 10:30pm. Midnight the pumps still running. I moved the
switch to off not timed and the pump went off after a little while. I moved it back
to timed and the pump stayed off.
2:20am the pump kicks in.... why?? the heating is on timed to start at 6:30 and
the hot water is off.
We have had the S35 or 53 code i forget which the missus has it written down.
This was just after they fitted the boiler.
Not checked it recently.
After finding some threads on here and another foru, i changed the pump timer
to 5 minutes not 20 and the heating down to 12 not 18. This did help with the
time the pump ran for. still ran excessively but less often.
In anticipation of their visit i reset them. I dont want them blaming me.
Sorry for the war and peace edition but this is now getting beyond a joke, I cannot
afford for the pump and boiler to be running all the time.
Many Thanks
Eric
