Recently I read somewhere that it's possible to add an auxiliary tank to
supply water heaters.
The purpose is, water comes from underground into a storage tank, where
the
temperature of the water is raised by ordinary basement temperatures --
especially in furnace rooms.
This water then feeds water into the heating tank at a considerably higher
temperature, thereby saving energy costs.
This is common sense. Is this technology available now?
Is the technology avalaible? Having a rooftop black tank and a mini
water heater is standard affair in Mexico and other countries that
dont have alot of extra cash. I took an old water heater stripped the
insuation and use it to temper incomming water, it goes up by maybe 6f
in a day. But you will need a tray under it to drain when it swets in
summer if your basement gets humid. Maybe a cheap uninsulated Well
tank will work. In summer you will save a bit.
Keep in mind water would freeze further up north. For solar water heating
systems, they use a closed loop of antifreeze to go to a heat exchanger
water heater. Keeps the antifreeze solution in the lines and on the roof
separate from the hot water which you might use for cooking, etc.!
