We have a RESOL DeltaSol system that was installed 20 years ago and has worked well until recently.
We are now experiencing:
- In the very how weather we heard boiling noises from the roof/attic.
- At the time the display panel was showing:
- TC 128 degrees
- TT 80 degrees
- TS 75 degrees
- I turned off the power supply and there was a gurgling sound and when I turned the power back on the TC temperature started to fall and the TT and TS started to rise
- We are now finding that the water in not heating properly. So today the panel shows:
- TC 128 degrees
- TT 39 degrees
- TS 31 degrees
- When I turn the power off and on, the TC starts to fall but the TT and TS stay low. After about 20 minutes they are now showing:
- TC 97 degrees
- TT 39 degrees
- TS 31 degrees
Please can anyone suggest a solution to this and recommend anyone who could come to fix it for us. We live in Stroud, Gloucestershire, UK
Thanks for any help
