Question for CESTB340 (Added 7/06/16 )
I have an Akvaterm heat store with a biomass heat source but also a Solar Array with an Immersun unit feeding the immersion.
The immersion is a BESTB 340, but after 18 months the safety appears to have become trigger happy. On biomass cycles the tank can hit 80 degrees, but generally that’s when there is no sun. I’m having to reset the unit daily. Replacing is straightforward, but is there anything I can do to improve performance?
