  • If you like pain and suffering buy one of these.

    Robert Barron 2 years ago

    I've had one of these stoves for ten years, rarely in those ten years has it ever performed as described. I am a retired perfectionist engineer, the flue was lined, a 300.00 flue cube cowl... []

    Stove expert replied: It does seem strange that an alternative stove can perform well in the same conditions as the Harmony was experiencing, normally if there is a flue draw issue this will be the same whatever stove is using it.

  • A solid, if a little fussy, burner

    We've had this stove since 2007 so have done a few winters with it. It was expensive compared to the others but was highly recommended and we liked the straight-forward looks and large window... []

  • Very practical stove

    Paul Kellett 3 years ago

    I''ve had an h23 for 5 years. Run it 24/7 Nov-Apr. No problems and no parts required. Burns overnight easily on wood or solid fuel. Uses cast iron liner instead of fire bricks so much more robust... []

    Stove expert replied: Try alternative smokeless fuels until you find one that suits the stove better as they do vary greatly. This may solve the riddle mechanism not working with the present fuel, some produce a lot of clinker and others more ash which is easier to riddle away.

  • Decent Stove

    Jared Dempsey 3 years ago

    I bought the stove ''hardly used'' second hand. The previous owners complained that it was too powerful for their small room and was difficult to light. I have one without the remote fancy controls... []

    Have another Harmony without the fancy air controls and this works fantastic even without a liner in the chimney , so when we bought the 23 and had it professionally installed with a liner too... []

  • Oval riddling grate poorly designed

    Richard Pare 5 years ago

    The chief design problem with this stove is that the riddling mechanism is connected to an oval grate. There is no way that this is going to remain free, using either wood or solid fuel. However... []

    Stove expert replied: Household coal is not recommended on a closed appliance, smokeless fuels should be used instead.

  • Fantastic Burner but Practise makes Perfect!

    Emma Roberts 8 years ago

    For the first few years we burnt anything on it from wet sticks, nappies, plastic until one day I returned home to find the house full of smoke as the chimney was completely blocked. After discussing... []

    Stove expert replied: Early mistakes burning anything on a stove led to a blocked chimney, only burn what is recommended on an appliance. Get the chimney / flue system swept regularly to insure that it is clear and will remove the gases effectively. Top marks given for this appliance from this user!

  • Generally fine but..............

    Simon Bromley 8 years ago

    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... []

    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.

    We bought this stove in May 2012 slightly seduced by the remote control option - just sounded great and perfect for properly controlling the fire. Sadly it just didn't work effectively. The... []

    Stove expert replied: Invaluable suggestions in the bottom paragraph, an expensive mistake to make if you get the wrong stove as not all suppliers will be so happy to exchange.
