Meet Neil! Neil cares about the environment and uses his expertise to improve fuel efficiency and save you money. Neil is very necessary. Neil is very boring. Neil cost €3800.
Moral of the story, spend the €100, get your damn boiler serviced!
We did have someone else have a look at it and give us quotes, we didn't just go off what Energia told us.
Also, I think it's worth noting that there was a mix-up between what we thought we were getting and what the guys who turned up had been told to install. We thought "zoned" meant what I described above, when actually it just means you can control the hot water tank separately to the heating, unless you specify otherwise and pay more for the extra "zone" of being able to control upstairs independently of downstairs. So halfway through the first (and what was meant to be the only) workday we realised the mistake, and we thought it was going to be a huge deal to change it and get what we wanted, plus a whole lot of extra money, but no! A couple of calls between us, the installers and Energia and it was all sorted with minimal fuss and just €250 euro extra. Energia basically (without any arguments!) accepted that they hadn't explained things properly and sorted it all out for us.
Also, the installers pointed out to me that Energia took a chance on quoting us for the job without sending someone out to look and that there was definitely a lot more work and materials needed than they could have anticipated (pipe had to run all the way up and through a giant hole cut in the floor), plus an electrician had to be brought in, as well as the extra days work they had to do....and not one peep was made by Energia about it. They quoted us a price, and they stuck to that price.
And I am not saying that for any reason other than I happen to be an Energia customer and I was really happy with the way they handled things.
I'll leave you with a pic of the monstrosity that is our new boiler, warts n all! All that efficiency requires all the copper pipe in the known universe apparently, making our lovely space-age boiler look like something that was cobbled together from pieces of junk. I'm trying to look at this as a positive, cos this means that we absolutely have to come up with a solution for the mess that is our utility room, and it needs to be done yesterday,cos look.....
