"Thank you for our wonderful water source heat exchange system which is now keeping the whole of our rather large house very warm and cozy 24 hours a day, heating our indoor pool and giving us plenty of hot water for our showers, baths and sinks. A miracle of modern technology! And the fact that it should use 60% less energy than our previous oil fired system is extremely gratifying for our pocketbook as well as our carbon footprint. Thank you for making it all possible."
