  1. This is the first I'd heard of heat pump clothes dryers, neat! A couple points about water heaters though. You state that if you have natural gas heating you'd "indirectly" be heating your water with natural gas. I can't imagine why you'd have natural gas heating, without already having natural gas heating your water. Also, tankless systems are "instant" the same way the water tanks are. That's what they mean, not that they're faster. The efficiency gains come from not storing the hot water, so I'm not convinced that you'd end up more efficient with the hybrid system you talk about being that you're still heating the water the "traditional" way first, and then just using the heat pump to maintain temperature vs just not storing the hot water in the first place. Really, if you want to look at heat pumps for water heating, most ground source home heating systems I see include both water, and space heating. That's the way to go. I really love the idea of a heat pump, but the economics are brutal. In my climate I don't need an air conditioner at all, and most of the winter is below where an air source heat pump makes sense. The end result is that the cost of an air source heat pump is hard to offset by the use in the shoulder seasons. As for ground source, that would be great, but until they come up with cheaper installation, that too is a non-starter. It's a technology I'm watching closely, and I hope to soon be able to go that way, but we're just not there yet economically.
