Transcape Plumber Posted January 30, 2017 Share Posted January 30, 2017 Some might find this interesting. We've just completed a hot water system in the Delta for the staff village of a guest lodge. 4500l Thermocube Tank with heat exchangers. Heat supplied by 2 x 24kw ITS heat pumps and 12 x 20 tube evac solar tubes in series. A 300m ring main feeds 24 tap off points supplying hot water for about 50 staff at a time and their kitchen and the camp laundry. superdiy 1 Quote Link to comment Share on other sites More sharing options...
DeepBass9 Posted January 30, 2017 Share Posted January 30, 2017 Interesting. Do you circulate the water through the ring feed to keep it hot close to point of use? Quote Link to comment Share on other sites More sharing options...
Transcape Plumber Posted January 30, 2017 Author Share Posted January 30, 2017 Yes, there is a small Grundfos circulation pump doing that. Other than the tanks, everything is in pairs, one duty and one standby. Quote Link to comment Share on other sites More sharing options...
___ Posted January 30, 2017 Share Posted January 30, 2017 I believe Stellenbosch University has a similar setup for feeding hot water to residences. Sometimes a number of nearby residences even share a heat source in this manner. The heat is circulated to keep it hot at the point of use. When I was there so many years ago, I remember how our residence NEVER ran out of hot water. My girlfriend (now wife) on the other end of campus wasn't as lucky though: They had geysers, and being girls and all, they ran out of hot water frequently :-) Transcape Plumber 1 Quote Link to comment Share on other sites More sharing options...
cvzyl Posted January 30, 2017 Share Posted January 30, 2017 plonkster, maybe that is more an indication of the difference in bath frequency and duration rather than the performance of the geysers. I know hygiene was not a very high priority for some of the guys when I was at US. Chris Hobson, ___ and superdiy 3 Quote Link to comment Share on other sites More sharing options...
___ Posted January 30, 2017 Share Posted January 30, 2017 I remember taking a 1.5 hour shower at 3am because I was drunk outa my skull and felt like death itself. Worked so well I attended my math class at 8am next morning. Me and 7 other nerds. First and last time I was ever that inebriated. Really don't understand how some people do it every week... :-P Sent from my GT-I9195 using Tapatalk Quote Link to comment Share on other sites More sharing options...
Transcape Plumber Posted March 9, 2017 Author Share Posted March 9, 2017 Update: I've just returned from a site visit and instead of 50 people using the system, there are now 90 people using it daily. They have used 244000l of hot water in just over a month (no water restrictions there!) so we are pretty chuffed that the system has held up with the added demand.
