This just has to be a No Shit, Sherlock moment for the hapless central planners of our funny little economy.
For the otherwise unenlightened, the backstory is that, due to Clean Air fixations, wherein chimneys emitting smoke are deemed to be a Bad Thang, there is a movement afoot to replace open fires and old wood fires, with 'clean' heat sources. And to encourage the masses, there are Gummint Subsidies to make a switch. (Bad puns, I've told you before. Sorry, Ed)
Heat pumps are a huge beneficiary of this move.
Oh dear, they cause a switch from sustainable, carbon based fuels (trees, unnerstan?) to electricity. Where peak load is generated from gas and coal. Nasty, dirty stuff, accordin' to some.
Which (spare generating capacity) NZ is rather short of at the minute. Double oh dear.
And heat pumps, particularly those of the reverse cycle persuasion, can also Cool. Cool pumps use power too! Damn, that wasn't in the Planners Plans! Folks were just meant to Heat with the things...And they Cool things in Summer, when electricity generation raw materials were traditionally stockpiled for Winter. Triple oh dear.
Funny, whodathunkit, them Central Planners never saw any o'this a'comin'.....
And you'd have to prise the remote controls for all them Heat Pumps from consumers' cold dead hands.....
