When I first found out about heat pumps I got super excited. Both heating plus a/c in a single system. It is ductless so that means I can have zone control plus no HVAC duct cleaning needs. No fuel I deliver for the heating effect. It is cheaper, cleaner, plus the system isn’t dependent on the fuel. The component takes up less space, is appealing, plus super modern. There also is easily little service needed with it. However, I did find one con. A heat pump system can’ t give heating if you experience hot plus cold temperatures below 40 degrees. Since I live in a freezing section I was devastated. I started wondering if there was a way to have the heat pump for A/C plus maybe something else for heating. I then came across dual fuel systems or hybrid heating. This combines a gas boiler plus a heat pump. For most of the year I get the amazing energy efficiency of a heat pump unit. The heat pump does all the A/C plus most of the heating. When the weather just gets too cold, the fuel changes. It switches from electric to gas plus tags the boiler in. I don’t need to do that myself though. The system automatically senses the freezing plus does it for me. I only need to use the less efficient heating opening for a month, occasionally two. For the most part I am getting amazing energy savings with my little system. For colder areas a dual fuel or hybrid boiler is the way to go when saving.
