Ricardo the point is that for the person or party installing the heat pump, you made some improvements to local efficiency from your point of view, but in the end all the heat pump did is massage local energy around, to improve your own environment, but the overall effect of this, on the planetis to increase entropy, or overall heat.
You might recognise this is just more colonialism of a kind, what colonialism does is improve the energy environment around the areas that are already energy priveliged, at the expense of the energy environments in other parts of the world, which are already underprivileged in terms of energy.
It seems harmless to us experiencing the benefits, but we don't take into account the cost of it to communities elsewhere because we don't personally experience any of the downsides, only the upsides to us personally, but now maybe we are realising there always is a cost to the planet, which will bite us all, sooner or later, it's an inevitable consequence of all energy expenditure coming out of a common, finite pot.
The only way out of it is to start using the energy offered for free by the sun, doing things with this to create things other than heat.
If your heat pump system uses solar energy direct as its energy source, not energy or heat extracted from the planet, then it goes from something adding to entropy, to something reversing entropy. Like that it has no overall negative effect. But most heatpump systems we see do not operate like this, they are designed to improve only the immediate environment of whoever paid to have them installed, and their overall effect on the planetary temperature has to be to increase it.
This probably doesn't make much difference to many folk whilst there are not many heatpumps, relatively speaking, but eventually, if a significant portion of the population was equipped with them, it will start to make a measurable impact.
The key is to always use solar to do all work needing done in the system, this is the only way to reverse entropy, rather than always adding to it.
