The Ground Water Heat Pump

All the solar energy you need to heat and cool your home is already collected and stored. You just need a ground water heat pump to use it.

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.
