Geothermal Energy at a Residential Location

[Dragomir995]

Actually, tsuchan it is considered geothermal if it utilizes the Earth's natural heat. That could mean the constant temperature at which the ground is kept year round. Therefore, it is Geothermal.

Geothermal systems created by vertical drilling go down several hundred feet. The ground temp which is captured through vertical piping is only about 50deg F. From there, the fluid runs through a unit which heats the fluid further, then is passed through an exchanger.

There are horizontal geothermal systems as well. These are used only when the homeowner has enough land area for the required ground heat capture. In either system, the ground temp is never more than about 53deg F.

Not actually geothermal, unless it uses heat from the earth (in which case, the drilling would go down some kilometres). Ground soure heating goes down just a few metres and uses heat captured from the sun. But anyway, good luck.

19 kilometers about the depth of the crust on the continental shelf. You really only need to go as deep as it takes to boil water. So you don't really have to go all the way down. Say 12 - 15 kilometers. The best drill whole on earth only has gone a measly 7.6 kilometers at best.

That was a Fla Heat Pump job in icf WALLS,

CENTRALIZED PUMPING... 34MBh / 10KWH /sq ft / school year..

now

HYDRO-TEMP COM de-centralized pumping...

YOU CAN STUDY HOW WE ARE DOWN TO ~8KWH

OR 27 mbH OER SQ FT PER SCHOOL YEAR

FOR UNDER $ 100,000

BUILDINGS USE A 1HP PUMP HYBRID

TO DIRECT COOLING AND HEATING AIR GOING INSIDE

OVER 600MBh at 20-25 dF days and pre cools too!

its noisy and is useless

I've had a ground source system since August 2006. My house has about 2000 sqft of climatized space. I have paid $75/mo for electricity on average over the past 16 months. That includes hvac, cooking, lights and hot water. My power company charges $0.046 per kwh which is very cheap. Our rates just went up this month. I should still be paying less than $100 on average. This system is the future. It's expensive at first but the payback is short with today's fuel prices.
