We are finally replacing our original 50 year old oil boiler with a new G115/34 Buderus. The installer, however did not recommend installing the smart logamatic controller unit and said it is very expansive (another 1000$ or so, installation on top of the full system including circulator etc @ 5400$) and most importantly is not reliable !!!
Is he right, or is it just too complicated for them?
Should we insist on the controller (we are willing to pay).
I don't know how much benefit you'll get with the controller given that this is an oil burning unit. It makes more sense with a gas mod/con boiler where you can run lower temperatures. With oil, I believe, the lowest you can run is 130-135F before it starts sooting.
