RobLe Posted Friday at 20:51 Author Share Posted Friday at 20:51 Thanks for link, expect I’ll get some. For now I used one of the other brass ones as it was easy to get, but I’ll get pressure rated ones - it’s annoying when stuff breaks. The outdoor ground loops and the indoor rad system both have header tanks - so there’s no pressure to speak of by the way. I’ve been running with 3 groundloops for a couple of days rather than the usual 4, the system has to try a bit harder and the heating COP dropped from 4 to 3.7. This is the worst time of year for the cop - the ground is cold, even though the air is starting to get warmer. Link to comment Share on other sites More sharing options...
