Here is a website
listing 45 brands of HOT AIR oil furnace with short comments, plus 2 examples (not recommendations)
http://www.hvac-for-beginners.com/oil-furnace-ratings.html
We have given each brand a rating
of from 1* to 5*. A 5* rating means that, if we were shopping for a unit for
our own home, that is the brand we would choose. Where more than one brand has
a 5* rating, we would choose the least expensive if it was available. We have
also included our comments and observations about the products based on our
service experience.
For a fair comparison, we have
ranked the brands in three categories. The first category is for basic units
which typically have the least features, the lowest operating efficiency, and
the lowest price. The second category is for variable speed units which feature
a variable speed blower motor for improved comfort and slightly better
operating efficiencies. They generally tend to cost a bit more. The final group
is for condensing oil furnaces. These units have the most features and the
highest operating efficiencies but are also the most expensive.
