ᐅ Wood-Burning Stove Austroflamm Uno Extra – User Experiences

EisvogelHello,
I need a new wood stove with a heat output of 7-9 kW, definitely with a heat storage system. I don’t have any problems with overheating the installation room since the entire building has a very open design. I came across the company Austroflamm because I read that they offer good value for money. I like the Uno Extra model both in terms of design and description. However, I found some old posts online reporting issues with blackened glass panels. If I’m spending around 4000 euros on a stove, I don’t want to have to worry about something like that.
Does anyone currently have an Uno Extra model in use and can share their experience? Are these problems still occurring or have they been resolved? The posts I found are already about 10 years old. Has the manufacturer addressed this in the meantime?
I appreciate any tips or recommendations, also for other models or manufacturers. Thanks for your help.
Regards, Simon

It’s easy to blame the stove model for this.
Some manufacturers, like Hase (our team members have a Dehli or Sendai model in their apartments), use a special air flow system over the glass that reduces soot buildup. You might want to look out for this feature.

Then I’ll chime in...
I’ve had a Justus Renor R stove for a year now. It’s a DIY store stove, also available online from Lidl, for example.
It features:
Primary, secondary, and tertiary air supply.
Suitable for continuous burning.
Can burn lignite coal (a lot, up to 6 kg (13 lbs), which provides 33 kW overnight—enough to keep even an old building warm).
Tested for airtightness (DITb certified).
Room air-independent.
Can handle logs up to 33 cm (13 inches) long (more if standing upright).
Weighs about 220 kg (485 lbs) with the stone lining, which can be removed with 4 screws, allowing the stove to be transported alone on a hand truck.
Has a glass cleaning system.
Works well even with little wood.
Checked yesterday: if you place a 12 x 12 x 33 cm (5 x 5 x 13 inches) piece of softwood on the remaining embers with air settings open normally, there are still embers left for rekindling after 2 hours.
Includes an automatic control.
Justus comes from the same factory as Oranier.
Costs about €1200 (approximately $1300), available at Toom, which sometimes offers a 20/100 promotion (20€ voucher for every 100€ spent). At Toom, the trailer is free to rent for 5 hours if you buy more than €200 worth. Loading with a forklift, unloading after a short removal of the stone by 4 people is easy and relaxed.
So, no, I can’t say anything about your stove, but a thousand-euro stove has everything you want.
Oh, and the glass stays clean. It ignites quickly but then burns cleanly again. In the morning, the glass is always clear.

Hase Dheli 124 for the older son
Hase Sendai Pro 135 for the younger son
A custom masonry heater with an Ortner GO13 69/53 insert for us.
All three stoves work excellently, are very well made, and burn—provided the wood is dry and the airflow is correctly adjusted (the masonry heater has an automatic fire control)—so cleanly that you hardly see any smoke coming from the chimney. The glass panels also stay clean. The two Hase stoves share one chimney.
