They have a 1940's model coal o matic.boiler in there old farm house and it is very hungry on coal. 4 ton of coal last month total this year 9 ton and r heading to buy more. The tag on it says 156000 BTU'S. Would your aa220 be more efficient and save them on coal.
I have a couple of questions.
What type of heat?, forced air, hot water, or steam?
When was the last time the boiler was serviced/cleaned and a manomometer reading taken?
The other question is what type of coal are they using??
Are they burning Bituminous?
If your relatives are like me, they have home that is poorly insulated and hard to heat.
