We're building a new house -- 3½ bathrooms w/showers, (master also has 80 gal tub), large kitchen, dw, etc.
Use pattern will be uneven--many days unoccupied, zero demand, then we could have a houseful of up to 6-7 adults on weekends.
Originally, we were thinking that the boiler wd make hot water and have a small 40 gal storage tank that could be fast recovered in periods of high demand. But we are rethinking hvac and the boiler is likely out. We are trying to get the geothermal numbers to work, but I've been forewarned that the desuperheater will not provide enough HW for our needs.
We are well aware of tankless (we've had one for the past 11 years) and realize that periods of intense usage won't make it unless we start ganging units together.
So is there a hybrid, with small high efficiency storage and a variable-rate burner-boiler we should be considering? The small storage tank will allow installation of a gravity-fed hw circulation system, and the small tank would take care of high initial demands.
We have propane, or cd go electric.
Thanks for your thoughts, Mark
