Benefits of Ground Source Heating

The very first word that may come to your mind when you hear the phrase ground source heating is "how". How can you heat and cool your home with the very dirt that sits outside your home, or business? Do you have to bore down to the earth’s core to use the hot magma?



The simple answer to that is no, and all you have to do is look at the outside heat exchange unit on a home with central heating and air to discover why this is so. You see, there are two parts to any air conditioning unit. One that blows air inside a building, and one that blows are outside.



The Freon in an air conditioning unit becomes cold when it's released in a line under pressure. You may have seen this same effect when you have used some aerosol charged spray cans. Your finger tip got cold.



Now when it's pressurized back up, the reverse happens in an air conditioner on a hot day. The Freon inside the line gets hot and it has to be cooled back down before it can be released in the line inside your building to cool again. This is what the outer unit is for, and to heat your home the process is simply ran in reverse.



That is why a central heating system is often referred to as a "heat exchange system". It uses an aerosol compressor system in it to basically exchanging energy that is both inside, and outside your home. So then what makes a ground source heating system so different?



The big difference here is that instead of going to a big fan unit sitting on the slab outside your home, the Freon lines are ran in an underground grid. It uses the actual dirt to either cool, or warm up the Freon in the lines instead of a fan. It's just that simple.



So then how much money can this newer of way of doing this half of your systems air conditioning task save you? In simple terms, it all depends on how much you use your system. You see it saves you money two ways.



First it means that you don't need to have a fan running full time outside your home and if you have a heavier system then you use a larger sized power hungry fan. Secondly, it's a more efficient method for heating or cooling your outside lines, and that too works to save you money.



You see, the better the Freon is heated or cooled outside your building on the reverse side of your central heating and air conditioning system, the less work your system has to do on the inside half of your system. Quite simply on hot days it cools better for less money, and on cold days it heats better for less.
