I thought I heard a drone overhead yesterday!I call fake news on @BKVP.
Looks to me like a brochure photo that is cropped and used in this site. He probably is burning a Regency since the BK unit does not throw off enough heat. Yes they burn slow and steady but peak heat is just not enough for his building envelope. I recall he is on a slight hill and has some wind. I think he tried a BK and it just didn't do the job well enough.
**all in jest and for humor only the above...hehe**
