I don't want to go through another summer heating dhw with my tarm wood boiler. I have a superstor hooked up to the oil burner, but the price of oil is high and looks like it's staying up there. I've been thinking heat pump. Is anyone using a Hybrid Heat Pump Water Heater? The GE model comes with its own 50 gallon tank and electric back-up. The Geyser system has been around for a while. Is there a benefit to go with the hybrid vs. the stand alone geyser?
