Hello. I have recently purchased a home and it has 2 pellet stoves already installed. I have made myself very famaliar with them and I am for the most part happy with there performance. One of them is a LOPI and it has a wall thermostat on it, and I find this to save alot of pellets and keeps a steady temp. My question is, where do I find a wall thermostat for my EF3? I looked on their website and I see part #EF-152 for the cost of almost $500 Is there any thermostat i can purchase elswhere to install on this unit that has a better price tag? I live in upstate NY and the cold weather will be upon us soon. Thanks in advance for any helpful response.
