I have gas pack (propane gas live in country , no natural) system and I am looking for more efficient and better system. My current system is self contained and I use a wood boiler ( sits outside for heat to house and shop) along with LP heat, which is costly, if no wood or there is a problem with boiler system. This is why I am interested in geo thermal system.
