Heat pumps use a compressor to move the heat. The higher the temperature difference, the higher the pressure ratio and the energy required. As you can imagine, if you want to keep your house at 70 and it's 10° outside it will take a lot more pressure than if it's 50°. It's not easy to design a compressor that works efficiently with a big range of pressures. One way that works well technically is to pump water through pipes into the ground, which will heat the water. The compressor then has a fairly constant 50-60° temperature to work with. You have to bury a lot of pipes deep enough to collect the heat from the earth - not so deep actually unless you don't have a big yard in which case you have to dig a deep vertical hole. Don't know the cost but not cheap compared to conventional technology. Tesla is using a heat pump for heating their Model 3 and Y. Maybe their technology can be used in home units. |

Emergency generator running on natural gas that would carry your entire home would be a serious expense. Maintenance, space, etc. Air conditioning, or heat pump? We can choose to get two. One in case the other one fails. Same is true of a generator. Choice, there is shortage of choices |

Even gas homes were shut down in Texas as propane pumping stations saw equipment freezing... I had a heat pump in Pennsylvania and it was fine although it was more expensive during cold weather as it had to use the electrical element.. but it worked fine.

The OPs avatar said he has lived in Texas and Louisiana, I don't consider them as the real south. Any place that gets snow, isn't the real south. I have all electric since 2011 and my highest electric bill, winter or summer until this year has been $91. January set the record, it was $126, a small price to pay.
I made up my mind a long time ago I would never own a home with gas. In '78 I rented a home in Pensacola while I custom built my permanent home. I couldn't be choosy since it was only for 3 or 4 months. I found a home with no hot water. I noticed the garage was brand new but the rest of the home was a 30 year old rancher. The gas hot water heater in the garage was new, but not connected yet. When I asked what was going on. They said a neighborhood kid was cutting the grass and set his can of gasoline down in the garage after filling the lawnmower, and he failed to put the gas cap back on the can. The fumes moved across the garage floor to the heater's pilot and blew up the garage and half the kitchen. One person was killed. |

sound like you are a trained HVAC Tec.

Take a look at geothermal heat pumps. They use the ground or nearby water as their heat source. They are extremely efficient, even in cold temperatures.
