Assuming a suitable sized system correctly installed you'll save in the order of 75%.
- tclancy 10y agoI actually built the Django app that powers the system "This Old House" installed (http://groundenergysupport.com/ http://groundenergysupport.com/) and one of the interesting things that came out of the app is what a dangerous assumption "a suitable sized system" is. I think the client has had trouble getting traction in the industry because some of the installers don't want to see their claims put to the test. Which isn't to say I think these are bad idea or ineffective, just that the sizing seems to be based more on what the installer can sell some times.
- anexprogrammer 10y agoInteresting. I'm not surprised to learn that about installers, there's a lot of factors in getting sizing right and pretty difficult for most customers to have confidence until it shows up as lowered efficiency. The app looks really useful, so I hope you succeed getting adoption.
