Review of Harmony 23
Generally fine but..............
Four years ago we did our research and then bought a Harmony 23. We did think we might run it on wood but despite the instructions telling you to build up a bed of charcoal, we could not get near to keeping it in overnight. We quickly and happily went to smokeless Supertherm and could then easily run it the 24/7 as and when we want, with three refuels daily (can do two) and one ash empty per day so very good to use.My continuing annoyance is I cannot keep the glass clean, no matter where I set the controls. I have tried other smokeless fuels and found no improvements. The other complaint is the door glass frosts up with tiny flecks in the glass itself. I am already on my third inner glass - and these are not cheap items. This last one was fitted in late November and was already showing signs of deterioration a month later. We don't run the fire up the glass and are careful how we refuel and operate the stove. We have a Morso in the other room which we have had for 10+ years, running on the same fuel with no glass problems whatsoever, so I am disapppointed by this problem with the Harmony. The other difference is the ash riddler is almost unuseable on the Harmony so we don't ever use it, but that isn't a big deal.
Stove expert replied: Crazing of the glass is a sign that the stove is slumbering for too long without short periods of fast burn to remove the gases from the firebox. These gases attack the glass causing a crazing that gradually creeps over the glass. The glass is not compromised when this happens it just doesn't look very nice. Recommend that you give the stove a good blast (all controls open fully) twice a day for 10 - 15mins and this should stop it getting any worse.
