I'm a lighting designer, not a hydronic expert. I just think
that the value of moving slightly heated water around is overrated. The cost to
heat 400 gallons of water 5F with propane is $0.01. So if your installed cost
for some kind of device is $500, you must heat 500,000 gallons of water 10F just
to break even. (propane at $1.00/gal, 80,000 btu's/gal, water @ 8lb's/gal.)

As Boiler
Do you also object to using tankless gas water heaters instead
of boilers
for combined space & water
heating?
