I purchased an hHP 22 in March of 24. It is a home run. So much so that in December of 2024 I bought an HP 21 to put in my garage workshop. That stove cost me $700 in piping and labor to have installed ... The fan motor seized in 3 weeks. So we had to return that stove. I purchased an HP 42 thinking it was a little bigger stove that it might work. When My pellet stove guy came to install it. He could not get it running. After a frustrating several hours back and forth with comfort built submitting tickets, we are still waiting for them to send us a control panel for a brand new stove that has not worked. I had animals in that garage. They have been in my library for 7 weeks. That's my review. I love the HP 22; however, after the company got sold, the cost of the stove went up $600. It's not lost on me that I spent $700 having a stove installed worked for 3 weeks. I could have bought another HP 22 and had a stove that works ... NOT HAPPY right now.
