Geo Thermal Heat pumps. Theory and operation from Sibley.

Video Title :	Geo Thermal Heat pumps. Theory and operation from Sibley.
Description :	Another from Mr. Herbert's Science class, using a practical, personal application as a lesson, we study the operation and repair of the Geo Thermal heat pump. Theory: Use coils under ground in your yard to cool and heat the freon in the Heat Exchanger, instead of the coils and fan that is usually parked outside your home in a big unit with a loud fan that is used to cool those coils with the hot air surrounding it. That is the old fashioned way and that is quite in-efficient, compared to Earth Cooling for free in Heat pumps. I hope this helps you understand the operation and why it works so well. Thanks for watching.

You have had geo thermal heating/cooling for over 25 years? The thing has paid for itself by now then right? Could you say how much the initial installation cost and what is your monthly heating bill?

This unit is 25 years old, but I just bought this place about 3 years ago. It cost about $14,000 when new. They are cheaper now. I spend about $200 a month in the winter and some of that goes for Gas because the emergency heat comes on when the Geo thermal cant keep up when it is 25 below. They work in tandem. It cost me about $200 a month just to heat my garage in the winter, with Propane, so there is a big difference.

I would love to get the geo thermal, but I have no basement, and my land is rocky clay, to dig into that would cost a fortune.

without any heat pumps no geo equipment a circulator and a ditch of about 7ft deep and 2ft wide and 250 ft long and damp clay about 52 degrees will support for over 2 weeks continuous output of over 14000 BtuH ( =4.1/2kwh like an elect water heater)for under $ 2500.00 w/piping ~ 33-to-31 deg f. just replaced a 1980 unit~~

Schools are down to 8 kwh (icf buildings) and the GT Earth Coupled Loop ECL Heat Pumps per Sq ft per School Year in KY USA with hydro-temp,com at under 2 (TWO) KWH for all COOLING HEATING AND Patented ON-Demand Hot Water reclaims WHILE in COOLING

now what happened to the GeoThermal Heat Pump blowing HOT AIR like me now, ? We measure 13 to 15kw (50MBh), of heat output = total out ! AAAAhhhhh the fluid into the Earth Coupled Loop was CHILLED by 9 to 11 KW Meaning the fluid FREELY delivered Earth Heat, MOVED (not made) by the compressor freon mass flow

right on

did ya get your calculator out ? the compressor does not make more than 25-30% of the heat, by compression from 4 kw to BTuH ( see bristolcompressors com ) h29j performance 20 suction and 100 discharge temps and related kw, add pump 200 watts and blower 500 varies)

Thanks kindly.
