Going to replace old waterfurnace unit with new 7 series. Desuperheater option $3700 Hybrid water heater $1200 $110/yr compared to a standard hot water heat at $700+ $450/yr. I would break even a little after the 1 year mark. What does everyone think is the better option? The hybrid heater would be in my heated unfinished basement. Stays 50-60deg even when in single digits outside.
