Bear in mind that while a resistive electric heater is 100 percent efficient (actually between 95 and 99 percent in the real world), a heat pump produces up to three times the energy it consumes because it transfers rather than creates heat. You may use a small heater to warm up a specific area, or to try and slow heat pump cycling, but you are probably not saving energy. I have a geothermal heat pump and it produces 4 or 5 times the heat that could be generated with just electricity... But it cost more to buy and install. It has drastically reduced my heating and cooling bills - and gives me free hot water all summer. For me the higher installation cost was quickly paid off and we now enjoy lower bills. Oh, I do have a wood stove and an inexhaustible supply of firewood (I own some woodland and folks cut on shares), so we are good there anyway.
As for dealing with rising prices, we are simply more careful with what we buy at the grocery store, and drive an energy efficient car - which we already had. As someone retired on fixed income, I also make sure to maintain my tractors and other equipment so I don't need to replace anything. If I need something by way of machinery, I go used. You can get some good stuff cheap - and without waiting.
We don't give up special things like traveling to see the grandkids or eating out, we just plan for it and make it work. But, then again, we lived through the steep inflation of the 1970s and survived.
