1980 I got a job on a pipeline in Algeria and started to work on heat pumps, or ACs as we called them back then. The problem was charging the units with gas, we had around 5 sites over a 310 kilometre pipeline, and one unit to recharge them with. So as an electrician, I would fix the fault, then have to wait for the one guy to re-gas it. I am guessing the gear was expensive, or we would have had more than one.
The problem today with the heat pumps, is selecting the right one. Youtube is full of cases where the wrong one has been fitted, or when there are massive price differences between the types, with even Heat Geek being criticised as to selection.
This type
has been used for years, and they did work well, in the main we want fan assistance as heat raises, so without fan assistance it can only heat or cool, not both so
or
high or low, both need fans, and also condensate pumps. The system has been used for years, in most hot countries, and we are fitting because of global warming, so not to be able to cool is daft.
But we are trying to replace central heating. Which likely poorly specked in the first place, in an old house, which likely has drafts, and humidity issues, and dealing with the general public, who have no idea what to expect.
So take a typical housing estate, two identical houses when built, but not any more, so you fit one system in one house, and another firm fits one in the other house, and one home has over twice the bill to the other, likely part down to what has been fitted, part to how used, and part down to changes to the two homes. And your in the firing line, as yours it the one with high running costs.
As to EV charging points, we are seeing unfair compertition, when firms like Octopus are offering a package, which includes a lower off-peak tariff if fitted by them, something you can't compete with.
Solar panels, we are seeing balcony DIY, which does not matter if it works or not, it will reduce how much is fitted.
What we are looking at, is the same as what happened with double glazing, the bubble has burst with that, it will be the same with the rest, so it is a real gamble as to when it will burst.
Fitting a heat pump in an all electric home, there is no problem with diffrent cost, oil, gas and electric, but moving from oil or gas to electric, yes at moment oil prices have soured, but for how long? And the compertition is


can installed ACs compete?
