We made the switch to geothermal energy for our home last month & couldn't be happier. Now I don't know how many folks have this kind of system, but it does make incubating in an LG incubator (or any basic incubator for that matter) a whole lot easier, less stressful. I had horrible temp spikes last year with our wood/oil furnace, but not anymore. Ambient humidity is very low this time of year, but humidity in the 'bator is maintained in the proper range all day. I just need to add a bit of hot water before bed every night. I'm so relieved & hubby too! I just wanted to share my discovery & see if others have experienced similar results with geothermal.
