Hey all,
I've been thinking of trying the DIY HP water heater too. I have a couple used in-wall (like window shakers) AC units, on e 230VAC, the other 120VAC. My WH is in a pantry in the kitchen, right next to the fridge. I was thinking I should add a couple of vents in the wall between the fridge and the pantry, and perhaps adding a small circulation fan, which would cause cool air from the HP WH to flow under the fridge, and warm air from above the fridge to flow back into the pantry, thus making the fridge and the HPWH both (in theory) work better. What do you guys think? BTW, my idea for the loop heat exchanger is to insert about 10 or 15 feet of 1/4 inch copper into the top of the WH tank via one of the top fittings such as the cold water inlet. A lot like the AIRTAP version.
