Hey all, I've got a 2800 sq.ft. house (2050 sq.ft. 2 story, 768 sq.ft. addition) with full basement being powered by a 3 ton and a 5 ton Climatemaster Water to Water Tranquility TWM Series geos with a closed horizontal ground loop and an 80 gallon storage tank. The house has 8 zones (5 hydronic radiant floor zones and 3 air handlers). I'm wondering about the best approach to go about verifying that the system is operating as efficiently as possible. I already have a real time whole house hydro meter from efergy installed, and it seems like the geo(s) are running a lot, since it feels like whenever I walk by and glance at the meter, it is running at 15kW or higher depending on what else is running. Usually the demand is met by only one of the geos (running in flip flop configuration). Hydro is expensive in Ontario and so far we have no solar supplement (although that was a future idea). Considering there are so many zones, it is likely that at any given time, at least one may call for heat and not long after the geo is working to top up the storage tank. I have considered getting an insulation wrap for the storage tank. I've wondered if a 2nd storage tank to increase storage capacity would be more efficient. I've thought about getting additional monitoring hardware to more closely watch the geo system itself. I was wondering if there was some advice out there on best next steps?
