Fix for low pressure in a geothermal ground loop

Описание к видео Fix for low pressure in a geothermal ground loop

I apologize for the audio on part of this clip.. Not sure what happened there. Anyway, this method will allow you to pressurize your ground loop without the use of a carbonator pump or similar method. You can use just water from a hose connection, or methanol (I used -20 washer fluid) pressurized with a Schrader valve. I prefer to add methanol and keep the freeze protection at a maximum. I am running this Econar 5 ton ground source heat pump system in Southeast Alaska, 5000 square feet, for less than 700 dollars a year. I do burn about a cord of wood per winter.
