So I got my stove installed this year (Oct 12) Heatilator PS50 and I started out with a ton of Ambiance Pellets and they were great, very low ash content, burned nice and hot but it seemed they burned quickly. So after checking around I found a supplier of Cubex pellets that will deliever to my house for the same price as I was paying to go pickup the Ambiance. Having gone through about half a ton of the Cubex I have had multiple startup issues where it seems there is a solid mass sitting right in front of the igniter. I do the regular maintenance where I clean the burn pot and use the shop vac to clean out the rest of the stove. I would say 3 times a week I am going over the stove to keep it clean...and with the ambiance this was fine....no startup issue. Now with the cubex at least 3 times a week I am finding myself having to chip away at this mass and sit and watch until the stove fires up. And last night as it was -22C outside the house went down to 12C inside...it was chilly! Has anybody had similar issues to this? Should I switch back to the ambiance or does anybody in the Kingston area know of another good brand of pellet to try? Thanks!
