I have enjoyed rediang all of your posts, especially the ones about geothermal. I did not know I could heat and cool my home from the temperature of the earth. I think everyone should replace there current heating and AC units with Geothermal Heat AC when they need replacing. You have sold me on eco friendly and energy saving heat and ac equipment. Thanks, Marn from Lewes, DE

Subject:strong smell

My house has a geo heating and cooling system. There is a strong oder coming from the heat exchanger in my house. The lines have been cleaned several times. We have had everyone from the gas company, heating and air, plumer, fire dept, sewer dept, now hasmat is coming to look around. No one seems to be able to locate the sorse of the oder. Any ideas on this problem?

I'll bet your heating bills will be about the same if you go elictrec. But elictrec is easyer to work with , a Heat pump with forced air. Works good in Oregon and we have pretty much the same kind of weather you got . Bill should be less than using a elictrec blower type . So down the road you could add your Solor into your main power source for more savings. Then you could afford to put in the GEO thermo you didn't want to put in, in the first place? I

After listening to sraeevl video I’m finding many inconsistencies on depth and I feel a little confuses I understand the heating system but I’m not as sure about the cooling system as the earth temperature is consistence all year round. How much electricity does this system requires as my heat pump is financially killing me. This subject is of great interest to me. And I would like to know more about it. Hopfully more people will start looking into this type of heating.

This is a very well set out set of Primary records mcnudeoting the lives of Henry and Susannah Kable and their first generation in Australia. I recommend it to any person wondering if it is worth the effort to purchase. Kable descended people would find it a necessity and other history buffs an educating story in order of events to add to their knowledge of early Australian pioneering days.

Thank you for the COP calculation. The only esuqtion I have is the 500 factor in the HE definition. I can see that a factor of 60 is needed to get from a minute to an hour but that leaves a factor of 8.5 that I am too stupid to figure out.This calculation is, however a rather cumbersome job and only gives a one time number. What the world needs is a display on the heat pump, (or on the thermostat or on the computer) that provides a continuous display of COP or EER. This can be done if we could measure the temperatures of the refrigerant at the entrance to the evaporator heat exchanger (T cold) and the entrance to the condensing heat exchanger (T hot).Then it would be simple formula: T hot divided by (T hot—Tcold) = COPThe problem is that I do not know how to get these temperature measurements. Maybe the manufacturer can be convinced to add this.Your thoughts?Don LloydAuthor of The Smart Guide to Geothermal , PixyJack Press,

Subject:closed looppressure loss

I have a Climate master tranquility 27 closed loop system. System was installed in 2007. My loop keeps losing pressure. The last time the tech was out he boosted the pressure to 37psi. Two days later it was down to 29 psi. One week later it was down to 15 psi. When the unit runs in heat mode the pressre drops to 4 psi. The tech does not know what is wrong, but says I do not have a leak and that the pump is working. How does this type of system keep pressure? Would there be a seal or pump that is not working?

Subject:geo loop presure

My geo unit is 16 years old and giving me vent temps around 88 deg. Is this normal? My closed loop presure on the pump (in)side is 4 lbs. the (out) side is 0. Is this pressure enough or should it be higher. What should I be reading on the in and out side? Is this what is causing the low vent temp? My unit has pete plugs do I add water on the in side or the out side and should the unit be running. Also in the winter should the hot water super heater be turned off or on . Does having it on rob me of some of the heat and cause my vent temps to be lower.

Thanks for your help

Subject:black carpet around edge of registers

We installed a geo-thermal system, when we built our house in 1998. After a couple of years, we started to notice a black edge on the carpet, under the register edge, and under the walk-in closet door, that has a register in it. We clean our filter regularly, and when I wipe down in the air duct under the registers, it doesn't seem to be dirty. We do have a humidifier, we use during the winter months, that is on the furnace. We just don't understand what is making the black stains. Also, during the heating months, I notice more of a black look on my dust rag, from the furniture and woodwork. If you can give us any suggestions, we would appreciate it. Sincerely, Tom and Sharon Bell.

I work with CBS RADIO and we are presenting an ENERGY SUMMIT in November. DO you work in the Philly area? If not, do you know another large geothermal installer in this market?

The SUMMIT offers sponsors an opportunity for on-air, online and on demand media support.

Good day:

We are building a new home in Brooklyn, NY and are interested in the benefits of geothermal heating/cooling. Are there any brochures that you can send with any info to help us make this important decision.

Subject:geothermal pods for water to water geothermal heating

I live on a cove and want to switch to geothermal energy to heat my home in Juneau Alaska. Someone told me that there is a company tha manufactures pods that can be dropped under water and hooked up to a closed loop system. If anyone has any information about such a product I would appreciate hearing from you.
