Gas boilers in the UK are soon to be banned.
An unqualified person working a gas boiler or gas piping is illegal in the UK and has been for decades. It's called Gas Safe, formerly Corgi, and it's a very regulated qualification in a very regulated industry for a reason. I get that. You could kill people.
Heatpumps have only one problem - they have a specific requirement to be installed / maintained by an F-Gas certified engineer (not quite the same as the above, far less stringent). Which is really nonsense, because the only part which is actually regulated is the refrigerant (and I get that happening in the days of CFC's etc. but we didn't have that certification back then!).
Nowadays the refrigerants are vastly different and thus the F-Gas requirement is really nothing more than "You must pay a tradesperson, how dare you try to install this fridge yourself" rather than some "you'll blow your house up if you do this wrong", like a Gas Safe certification.
Which is why I went out of my way - and I imagine a lot of other people have - to find heatpumps that don't require that certification. Which leads me to an ultimate irony. You can get them, they are commonly available, legal for sale, and they just use a different refrigerant to the regulated ones.
One of which is R290.... propane without any additives so you can't smell it. So I can legally install a heatpump which uses odourless propane in my house myself, but I cannot legally install one that uses the same refrigerant as my own fridge. Now, it's not a lot of propane, only 200g or so, but still... I find that ridiculous.
So before the law catches up with that, I self-installed two heatpumps, each with the capacity to heat or cool my entire house (which is only small) while I still can.
And why did I want to go the self-install route? Is it because I'm poor? No. I could afford an engineer. But get this - the only UK government subsidies for heatpumps require you to use the certified engineers, AND they need you to have a bunch of requirements for your house. Houses are bought or sold with Energy Performance Certificates (EPCs). These tell you how energy efficient the house is based on.... some random guy having a quick look and guessing. It's literally that bad.
My EPC says that I'd need to fit cavity wall insulation, party wall insulation, another 150mm of loft insulation (in a loft you can barely crawl already), change all my doors etc. in order to get it to the grade where I'm eligible for a heatpump grant, which is also pretty much only available if you're out-of-work or disabled, and your house passes the grade, and you buy a HUGE whole-house system, and you spend thousands yourself. Which is weird because this house is the warmest and best insulated house I've ever lived in in my life and I have no intention of ever adding any more insulation ever, anywhere on it.
And then they go "Why aren't people buying heatpumps?! We even have grants!".
Because the GBP800 heatpump I bought is using an unregulated refrigerant and I can just slap it in myself (two holes in the wall, and a plug nearby, that was the only requirement) but your GBP5000 towards about GBP10,000 of heatpump system is only available if I already can't afford a heatpump anyway and I spend another GBP10,000 insulating my house unnecessarily to get it. Also, you don't advertise the fact that non-F-Gas heatpumps exist and work perfectly well, just the same.
So I bought the GBP800 heatpumps. They are amazing. 200W of actual draw over the course of an entire day (i.e. 1KWh for every 5 hours it's on) and it keeps my "poorly insulated" house at 20C when it's below 0C outside.
If you want people to use heatpumps - offer an unregulated install route. Preferably a safer one actually! And then advertise it like mad.
Pretty much, heatpump grants only exist in the UK to drum up a new trade, a bit like solar installs where - again - it's a regulated industry and they only provide grants to those systems which entail regulated professions doing the work at enormous markup and on a large scale.
"We're getting rid of all the gas boilers / cookers, which means Gas Safe engineers will be basically out of work, which means we retrain them as F-Gas engineers with similar skills and then MAKE PEOPLE USE THEM."
Sorry, I get the concept, but that's not the way to meet your energy and climate obligations.
P.S. Slashdot classic still can't handle simple symbols that aren't even Unicode, hence GBP instead of.... let me try... £ ... nope... still doesn't work. But SoylentNews (also based on Slash) works fine in the same mode!
