The easiest and best way to establish your BTU requirement
is to look at your
current furnace.
There is normally a label on the furnace that tells you the BTU
output.
If your furnace is 90% efficient, you may have to multiply that
amount by 0.90.
If not, call the manufacturer or go to their website with your
model
number
and they will tell you the rating.
Any furnace rated at 180,000 BTU NET output or less, can be
generally be replaced with our Hyprotherm 185,
assuming that it heats your home well now.
Of course if a furnace is
oversized (e.g 100,000) and can really
heat your home with 50,000 BTU, then that should be considered and
we recommend it because you will load it half as much, as little as
ONCE A DAY!
There is no such thing as a furnace
that is too big because it is not like an air conditioner, where if
you get one too big, it becomes inefficient.
This is like getting a bigger propane or oil
tank! You can load it with more wood (full rounds - no
splitting!) and it will burn longer and therefore you will load it
less often. No one has ever complained and said that I sold them one
too big. In contrast, many people have said, "I wished that I
listened to you!"
Use
square footage estimates below.
The Hyprotherm 100 STORES 100,000 BTU, ready for immediate use, unlike others who
give you
phony numbers of what a furnace can do at maximum output,
which may be 20 minutes.
Also remember, that the home should be no bigger than the rated
square footage of the boiler, unless in a southern climate like us in AR or in NC or further south. See listings
HERE
But remember, it's more critical to have a heat exchanger with the
correct output or bigger. If the heat exchanger is too small, you will never get enough heat,
no matter how big the furnace is!
Which furnace do YOU need?
Our standard furnace, the Hyprotherm 100,
is just shy of 100,000 REAL BTU - no
funny math here!
The Hyprotherm 185 is 180,000 STORED BTU
The
Hyprotherm 265 is 260,000 BTU
The Hyprotherm 300 is 290,000 BTU
The Hyprotherm 350 is 340,000 BTU
The Hyprotherm top loaders go up even higher
with the large capacity of wood that they will bold' up to 216 square
feet!
