Hello: I've just had a new Axeman-Anderson WL 119 oil boiler installed in my home 2 months ago and they've already had to replace the aquastat. Even before it was replaced, I noticed that the boiler was constantly firing on even when I turned my heat off on my thermostat. I've had the technicians over multiple times (they set the aquastat wrong and it kept the boiler on constantly), and I finally got an answer today that the it was normal for the aquastat to turn the boiler on to keep the water temperature in the boiler above a minimum temperature. They said that this was to keep it from rusting out.
Since I know nothing about boilers and aquastats, my question is this: is it normal for the boiler to have to fire on every hour or so, even with my thermostat off and the temperature outside in the 60s-70s?
My boiler is located in my cellar, which stays a bit cooler than the rest of the house. They gave me the option of having an on-demand aquastat installed. As oil prices are not cheap and I do not like the idea of my boiler running even in the middle of summer, I think this is the best way to go. However, I want to make sure this is the right choice. What are the consequences if I choose to go with the on-demand aquastat? Should I stick with the current aquastat? How do I determine what the proper settings should be for the aquastat?
I would appreciate any advice that I can get on this!
Cheers,
Mimi
