To be fair, I think the varied opinions on this forum, are what make it. And its a good source of information that I probably wouldn't go searching for otherwise. You don't have to read them.
It's also completely relevant to the title of the thread. lol
Anyway, I'm following the whole thread with interest as I'm in a fairly old/energy thirsty house. With oil central Heating, LPG hobs and Electric everything else.
We had a new Oil boiler fitted about 4 years ago, after the 25 year old one finally completely died, and it has helped the oil consumption substantially. Its just a shame Kerosene is 3x the cost now, so probably still worse off. (Don't hear the news/martin Lewis trying to get help for us oil burners).
I did have a look at Air and ground source at the time, but we would have had to increase our radiator size/amount significantly or dig up all our floors and fit underfloor heating. Both of which not desirable.
Better wall insulation would make a big difference, but we will do that as and when we re-decorate each room.
Electric-wise, after the first winter electricity bill (it was large) we had there 9 years ago, was to replace the 112 x 55w downlighters for LED, along with the 40 and 60w lamps and all the dusk-dawn outside lights etc which was a big outlay back then, but made a massive difference.
There are still loads of things we could do, like actually switching off unnecessary appliances, TVs, amps etc etc. and I think we will have to start doing that.
I didn't ever want to put solar panels on the old welsh slate house roof, so have always disregarded it. But we will soon be building an oak cart lodge, which obviously needs a roof, so wondering if it'd be a good opportunity to get some Solar panels on there, or maybe on my Garage roof.
Watching this thread with interest.
