So what is the energy saving payback period for the energy used in producing the raw materials, manufacturing, shipping and installing the required items?
Ditto the expected "pollution" recovery period?
How much "pollution" do we create now in order to say that pollution has been reduced in the future?
And since this rush is mostly driven by the CO2 wheeze - how much additional CO2 output do we create now (at a time when we are told by some that even immediate reduction will not be enough to "save the planet") in order to satisfy projected claims that humanity can control the planet's climate at some future point and thus prevent claimed overheating possibilities?
Anyway Mike, you are away from home a lot of the time compared to many. Your opportunity time for energy saving would, presumably, only apply when at home and thus is greatly reduced. To make full use of your investment you would need to stay at home more.
BTW, I love the way that people see a heat pump, especially a ground source heat pump, as a fantastic way to make a lot of energy savings.
The down side is that in certain places the ground conditions mean that the components need replacing after a decade or less. That might well fall foul of revised regulations and so require more extensive and earlier than required changes in other parts of the system. That comes with a cost not the least cost being that related to a shorter lifetime for productive use of items that consumed energy during their production.
Early unplanned obsolescence. Or, described another way, wastage.
Still, our leaders are good at wastage.
Refurbishing the Houses of Parliament, for example, is a complete waste of time, money and energy.
It makes a nice vanity project though.
