I installed a heat exchange between my shower drain and the water heater inlet. Still need to do some calculations but the heat recovery is dramatic.
I’m using a metal wafer pool heat exchange and a boost pump for pressure on the outgoing side.
- giantg2 4y agoThe way my house is set up, I doubt it would be dramatic for me. My hot water is already turned down. It seems like a big project to install a heat exchanger given the space it would need to be in.
- Scoundreller 4y agoI just want to superglue old aluminum heatsinks on the water inlet pipe, but people are going to think I’m nuts… I have to admit I haven’t thought out whether this will galvanically disappear the copper. I’ve also thought out putting a 50’ spool of pex inline, but unsure of pressure loss issues. Or maybe that would be good for the house pipes…
