New oil fired, forced hot air furnace as the backup system, with a 5T air-to-air heat pump, plus an LG Mini-split air-to-air heat pump for a family room addition. The heat pumps reduce the operation costs by approximately 50% vs. oil.
Also recently added a GE 50 gal. heat pump water heater with an 80 gal. tempering tank. This is an excellent combinatin that has reduced the electric power cost for domestic hot water by more than 60%.
