They make economic sense if you have to upgrade to a new gas boiler (from an old gas boiler) or even worse, a oil-based boiler, but only under BUS conditions.
In other countries, though, where they are widespread, they are cheaper to both install and run than gas boilers.
Broadly disagree but agree about a specific element.
I think there’s plenty of justice between two people of give or take equal wealth.
Money, unfortunately, does help one prepare a defense or attack better than those without money. So in that sense, justice is very unevenly served between parties of unequal wealth.
