My brother is working for a research company. One of his projects required him to give a report on the in depth research on alternate heating systems. He did a thorough study of the geothermal heating system and was very impressed by it.
Consequently, he changed the system in his home from electric one to geo thermal and has been raving about it for the past six months trying to convince me to do the same in my house. He even sent me the engineer who installs this system and gave me a quotation for the same. After much persuasion, I have decided to give it a try.
