I had a Rennai installed last Dec and happy with its performance so far. It's set at 125f. The inbound flow is around 36f and it takes relatively little time to heat. Plenty of hot water for the jacuzzi tub and anything else. 10yr parts and labor warranty by HVAC company I have been using for years. Cost=3k. Sounds expensive but add that to the new G71 furnace I just installed and I'm happy with the results. It's a little too soon to tell but I expect savings of over 1k/yr compared to my earlier set up.
Now, why aren't you preheating your water? My dad had this wonderful set up on his home in Hesperia and he had unbelievably low gas bills. Water was preheated through roof system similar to solar panels.
