OUTDOOR FURNACE REVIEWS

  • I got this wood stove about 5 years ago, and it has saved me a ton of money! I cut my own wood from my backyard and around the area that I live. This equipment is a much better choice than propane for my type of environment and lifestyle. I had grown up using propane, and had even spent a winter using only our fireplace in the basement, but it wasn’t going to cut it. So, I had a local company install a Crown Royal Wood Furnace to heat my house. Luckily, once propane prices rose astronomically we had already had it installed and avoided the financial stress. I would highly recommend this equipment to anyone. It has done wonders for us. We are saving money, “living off the land”, and our house is sitting comfortably.

  • I received my stove last week. It is now up and running. I am in total love. I stay cold due to medications. I can say, not any more. The people were wonderful to work with and talked us through any issue with a solution at the end of the conversation. The friend who helped install the stove has a different brand, older stove, after seeing how well this stove is made, he may be purchasing one (outdoor wood furnace) soon. So awesome!!

  • I am very happy with my stove. Recently purchased a RS7300 coal indoor boiler (indoor furnace). Installed in November after owning 3 Aquatherms in the last 20 years. I now finally own an exceptional boiler. Easy to fire controls work well love the ash pan. I now can burn coal and wood. Average refill time every 12 hours. Very little smoke when firing. Stove has burned cleaner than any Aquatherm I have ever owned.
