We have been asked several times how we made out this summer. The brief answer, great!
The long answer:
Window screens: The window screens did not come with the windows so we had to have them locally made. Klearwall indicated to us that this would be more economical as they would not have to ship screens from Europe, fair enough. They did however, forget to send them to us and I had to ask to have them shipped which caused us a delay in getting the screens made. When the clips arrived we realized that they were not a product that we were wanting to use and we chose to use screen clips that we purchased locally at Home Hardware. Long story short, we could have made the screens and installed them much sooner than we did. We were having some overheating issues before we installed the screens as we were not able to leave the windows open overnight as the bugs would find their way in. Once we installed the screens though, we were able to enjoy the benefits of passive night time cooling. We would open the windows in the evening and overnight and then close them in the morning to trap the cooler air in the house.
Poor man’s geothermal: Hmmm… if only we had this working properly I think it would have made a substantial difference. We had it running and were seeing about a 10 degree difference in the air temperature from what was outside to what was entering the HRV. Unfortunately, we have had trouble keeping the system running as we continue to get air in the system so the pump will not run. This is a kink that we definitely need to work out.
The verdict: While it would definitely warm up during the day in the house, we always sat at a temperature that was much more comfortable than outside. It often felt like we were walking into an air conditioned space when we walked in even though the indoor temperature could be in the high twenties. Are we happy? Absolutely!
It will be interesting to see when we actually turn the heat on. We are still sleeping with the windows open, who doesn’t love that fresh night time air, and we sit at a pretty constant low to mid twenty temperature. In our previous home we burned wood pellets into June and would start again the beginning of October. I do not foresee us needing any heat that early at all.
