Saving hot water with a Heat Trap? Anti-Thermosyphoning

Xringer · 04-01-10, 05:15 PM

I've seen a few examples of this idea on the web. The hot water output is looped down (or up then down)
to trap hot water in the water heater and keep it from slowly flowing upwards from the heater to the pipes above it.

I'm thinking of using the double loop version when I do my new mixer install..

Since it's going to be PEX and not copper, not much cost involved..

What do you guys think? Good idea?

Thanks,
Rich
