On first blush that sounds like the way to go, but for most existing homes it would probably be suboptimal.
To reduce costs, a device like this should be localized to a room rather than force you to route the water from your shower all the way back down to a water heater. The latter would necessitate a major plumbing addition.
- jwilliams 18y agoAgree - and given the locality (i.e. there is someone using heat/hotwater right there), it would make sense to use it as soon as possible. If you didn't have locality, the water heater approach probably make more sense -- i.e. Your washing machine, dishwasher, which tend to hold on to hot water and then dump it at the end of the cycle.
