Hot water recirculator
All 3 homes I've ever lived in have had the same issue. When I turn on the faucet to hot it takes a while for the water to turn hot. I've just always kind of assumed that's just how houses are. There is a lot of pipe between the hot water heater and faucet, it made logical sense why but has always felt wasteful.
Come this week I discovered a hot water recirculator pump. Not that expensive and relatively easy to install. It feels too good to be true and I'd happily pay parts + install to have near instant hot water at all my faucets.
Why else aren't they common or why shouldn't I do it?
