Hi I'm new to the forum. Just had a Climate Master Tranq. 27, 5 ton unit installed this past June. I have not noticed much change in my electric bills. My question is: why would I feel a change in my water temp from warm to cold while taking a shower? This never happened prior to the geo install. The Installer appears to have the desuperheater hooked up correctly , 2 - 80 gal tanks, one has power. Thanks for any and all input.
