Resilience is a special subset of durability and reliability. Something may be built to last and work as intended for a long time, like a solid old car. However, it may not adapt well to contemporary uses, or lack modern safety equipment and amenities, or otherwise become obsolete in a new and changing context. The car may run great, but it runs on gasoline and was, possibly, even intended to run on leaded fuel. And, for example, it will never be autonomous.
Systems in your home that run on electricity are resilient in that, no matter how the electricity is generated, or how much that method of generation changes, electric systems and appliances will continue to work without skipping a beat.
Electric infrared radiant heat requires few to no moving parts to fail or wear out. And the parts that can eventually fail (usually after decades of regular use) will, very likely, continue to be readily available or effectively substituted for the foreseeable future. These appliances can easily be salvaged from a building that has outlived its usefulness and be reinstalled in another setting. Since they are usually mounted well above the floor, they are far more likely to survive all but the worst floods. They don’t have any pressurized refrigerants, so there is no chance of toxic leakage that will also render them useless until repaired and recharged. And they can be easily adapted to ‘smart device / smart home’ control systems, no matter how that technology evolves.
Building things to last and be readily repaired is great. Building things that can also survive and adapt through rapidly changing technological landscapes, large-scale infrastructural changes, and even increasing environmental threats is even better.
