no heat

[erniej9]

I have a Dansons Pelpro 120 Home Heater. I used to get a lot of heat from it but not lately. I have a brisk, clean hot flame but hardly any heat. It's had a good cleaning but with no luck. The flame is exactly as it was when I got plenty of heat.. I'm using the same fuel. New combustion fan. High limit switch. New door gasket.

I am assuming a good cleaning included the heat exchanger?

I even made a curved wire cleaner so I could get into the top of the heat exchangers, and I vacuumed them.

Assuming the stove is clean and in perfect operating order, something else must be different. Lower outdoor temps, roof cleared of snow, a moist batch of pellets perhaps.

When you replaced the combustion fan, was it with a stock unit with the same RPM'S and number of fan blades? I saw one retailer selling an 'upgraded combustion fan' for Pelpro's that had two extra blades. To me, I immediately said that it would blow more heat up the stack and leave less for the room.
