Creating a ground water heat pump requires drilling two wells on your property..

Thinking about solar energy? Good for you l I’ve been in
the heating and cooling business for many years, and I’m
completely convinced that solar energy is the most
practical solution to the energy crisis.

However, you may be shocked when you find out how much
solar collectors cost. Relax! I’ve got some good news for
you: the biggest and best solar collector in the world is
already in place at your doorstep. It’s just waiting for
you to use it.

The biggest and best solar collector, of course, is good
old mother earth. Every day she soaks up tremendous amounts
of energy–enough energy to heat and cool every home,
school, office and factory in the world. Where is all this
energy stored? Well, much of it is stored in ground water–in water just 50 to 100 feet deep in the ground.

And you can tap this energy for your own use, to heat and
cool your home. All it takes is a ground water heat pump
and a couple of water wells. That may sound like a
complicated and expensive system, but it’s really a very
economical system that can pay for itself in fuel savings
in just a short time. Let me tell you how it works.

Here in Virginia, for example, the water 50 feet deep in
the ground stays at a constant temperature of 60° all
the time, summer and winter. With a ground water heat pump,
instead of cooling the outside coil of your air conditioner
with hot outside air, you cool it with 60° ground
water. Your compressor has to work only half as hard, and
you cut your electric bill in half.

In the winter, it’s just the reverse. Instead of burning
expensive fuel, you use 60° ground water to boil Freon
in a heat pump. Again, it’s a very simple system, and the
saving in your fuel bill is enormous.
