“The hopper expansion was a simple install. I am only giving it 3 stars because while it adds 32lb of capacity, it makes a significant amount of pellet capacity in the original stove inaccessible. Before adding the extension, I could use my hand to push the pellets in the hopper to the edges. With the extension, the pellets that fall into the original hopper are shaped like a cone and it leaves lots of open space. If I had to guess, it is probably +32 for the extension and -15 or -20 from the original stove.”
“Best purchase I've made since I bought the original stove. It is 7 degrees right now and my stove with the hopper extension keeps my home at 72 degrees all day and night without refilling.”
“I called just after receiving the extension. It doesn't fit the hp22n but it sold for it. Was told it was made for all the other stoves and works on mine. Works maybe but looks terrible on it. Even the securing straps for the back won't work.”
