Tracking our Geothermal Lessons - Hot Water

When we bought our geothermal unit, we were told that it provides 100% of our heating and cooling and about 60-80% of our hot water needs. This has generally been the case except for one point to clarify. The heat for the hot water is dependent on the furnace running so in the shoulder season when your furnace may be off (and you don't need your ac on yet) none of your hot water needs are going to be met by the geothermal system. This is ok as we have an electric water heating system but it is good to know that this is how the system works in the real world.
