Daniel,
That sounds like an intriguing technology, much
along the lines of an air to air heat exchanger.
Thanks for the recommendation. These systems
could keep a lot of CO2 out of the atmosphere if widely used.

Maybe. I designed my own house to incorporate this. The most efficient are
the vertical type, and at 6' the company advertised 20% recovery for about
$1,300 if I remember correctly. This I'm sure is for a new copper pipe, and

And a big maybe for Offgrid where we like multiple ways to
charge/heat/cool and make hot water. The default method is almost always
the most reliable. For a typical home a 50 gallon propane tank water
heater with a zinc change every 7 years is the norm.

What are the issues with tankless water heaters? I have heard them
described as having "issues", but I haven't read anything that describes
what they are. They are very popular where I live. Any info? Thanks, Chris

For Offgrid with minerals in the well water, getting the right flow, the

for many but if you do add an open loop solar water panel, you need a

Ah,off grid. I see. That makes sense. I wouldn't use it place of solar,

It used to be that “tankless” water heaters were very sensitive to stable
temperature production as flows from single handle facets shut down the hot and
opened the cold flows.
I can fully recommend the Rianai heaters of today as we have 2 in offgrid and 0

Rianai have 3 major issues when used off grid.
1) The phantom load when I checked was over 30 watts continuous. That's
over 700 w-hr/ day.
2) They need pure sine wave, and even have trouble on Trace SW
inverters. (One system I took over has a separate Exeltech on its own

Ray, Chris, et al,
Both Paloma (185,500 BTU/h) and Bosch (117,000 BTU/h) manufactured
natural draft heaters that used zero electric, just like common tanks.
Because the majority of these units used a standing pilot, they were
castigated by the energy bureaucrat folks in favor of something that
