I must disagree with that statement.
Check the specs for most stoves and you will see why.
Example:
Avalon Astoria
BTUs Per Hr_Heat Setting___LBs/Hr
13,940 _______LOW_______1.7
45,100 _______HIGH_______5.5
The high setting for my 2,000 SqFt fairly well insulated house is only needed when it is -5 to -10 degrees F below Zero
or zero to 10 above and high wind speeds!
I use the low setting which is almost 14k BTUs per hour for very comfortable heat most of the time when it is 20 to 30 degrees F outside
The following chart is a guide for heating the whole house (Split Entry) with the stove installed in the center of the basement with 2 registers with a convection fan and a doorway fan in the doorway to the basement.
Pellet Stove Heat Setting, with the Air Restrictor on 2 and the Convection Fan on 6 (Highest)
Wind Speed +or-5 MPH
5 10 20
Outside Temp +or-5 Degrees
v v Astoria Heat Setting (1-6) Astoria Heat Setting (1-6) Astoria Heat Setting (1-6)
0 4 5 6
10 3 4 5
20 2 3 4
30 1 2 3
Example1: Early Saturday morning on 01-30-2010, The wind speed was 20 MPH and outside temperature was 4 degrees. the chart says 6 for the heat setting. At that time, we had it set to 5 when we were asleep and 6 when we woke up for more warmth and comfort!!
Example2:
02-07-2010 at 2 pm, the temperature was 27 degrees F, and the Wind Speed was 9 MPH. Therefore, the chart above puts the heat setting between 3 and 2 (slightly closer to 2) We have it set to 3 for comfort although 2 would be adequate!!
He did not mean your stove Don... He meant the US Stove, its rated at 50,000 and if I remember. You were the one who pointed out, that its minimum feed rate is 5 lbs an hour. He was not stating every 50,000 BTU stove. Mine is 47,500 also and its max is 5.5 lbs an hr. Both of our stoves "Are" efficient. The US Furnace in question is not.
