I bought a Sunheat heater at the beginning of the winter season. Living in Minnesota, I can tell you that heating costs for natural gas can get out of control very quickly. This heater has provided me with an alternate option that uses much less energy and will pay for itself multiple times over. I have not had any mechanical issues and am happy with the customer service I have experienced so far. Hope this review helps.
Also live in MN. Looking at the Sunheat heater. Yours is the only positive comment I found. Do you have any more info? Contact info: mnjcars@mchsi.com 507-375-3556 Thanks, Marilyn Carstensen
