It heats up to 28-30 squares and has a fan. It has a curved glass front and is probably the best looking heater on the market as well as being powerful. They often run promos with free flue kit too. Lopi is another great heater but to be honest the silhouette beats it. The slow burn overnight depends a lot on the wood you use but baffles and fire box play a big part in this also. The good thing about Norseman is spare parts are always available too. Maybe have a Google and visit a store to check it out Re: wood heaters - inbuilt. for large area 3Jun 01, 2016 9:05 am Also I had a Norseman Nevada in my old place and she served us well. It was already there when we moved in so would be pushing about 20years old and still going strong. We replaced a few bricks and the baffle once. I can't stress enough that the wood you burn has to be well seasoned otherwise the heat output is compromised. We bought a few dud loads in our time! Re: wood heaters - inbuilt. for large area 4Jun 01, 2016 9:22 am I have Quadrafire and it's excellent, have a look at it. It burns completely. I went through all winter without having to clean out ash. http://s1321.photobucket.com/user/brank ... q.mp4.html Foremost Building Expert in Australia,assisting with building problems/disputes, building stage inspections,pre-contract review advice for peace of mind 200 blogs http://www.buildingexpert.net.au/blog Re: wood heaters - inbuilt. for large area 6Jun 01, 2016 10:38 am Stewie D Your photo doesn't appear BE.

Maybe have a Google and visit a store to check it out thanks for that I did go to a bbq galores. the chap there told me that the Saxons were their top of the line' in terms of performance. not necessarily the most efficient though. however the saxon did not have an insert that was big enough. will revisit the norseman in that case. it has to be an insert though as I have a fireplace built for it.. free standing out of the question. Re: wood heaters - inbuilt. for large area 9Jun 02, 2016 8:13 am Yep you can get the Norseman silhouette in a built in. We didn't sell Saxons at all but I know the franchised stores did. That's was a while a go though. Haven't heard of quadrafire. Re: wood heaters - inbuilt. for large area 10Jun 07, 2016 1:24 am can anyone explain the measurement of heat output in kW? the numbers vary so wildly with different manufacturers I suspect they are measuring different things for example : the masport I9000 has an 'estimated peak output' of 24kw my saxon blackwood freestanding heater has got a 'heat output' of 11kW A similar sized masport r5000 to the saxon I have has a 'estimated peak output' of 19kW! Re: wood heaters - inbuilt. for large area 11Jun 07, 2016 9:19 am I'd take any of the ratings with a grain of salt. The estimated peak output for instance would be in optimum conditions and nowhere near what you would get out of it in the real world. It's a bit like the output of electrical motors. They claim a high initial figure but under load and for a sustained time they would be probably 30-40% less. The output figure they claim is one thing but how efficient they are is another. Stewie Re: wood heaters - inbuilt. for large area 12Jun 09, 2016 3:15 pm i suppose if there was a standardised protocol for testing (i suspect there isn't)… then numbers can be comparable. a bit like fuel consumption figures for cars i suppose. difficult to achieve in reality but at least there is a way to compare relative performance. What does efficiency of a wood heater relate to? what does it actually mean and how does it relate to heat output? the way i understand it - it is a measure of how well it converts a given mass of wood into heat energy. not necessarily relating to how well it can heat the room?? i am most interested in the ability to heat a large space and the amount of wood i need to make that happen is a lesser consideration as i have a large supply of hardwood (never ending supply!). Some clarity would be great. Re: wood heaters - inbuilt. for large area 13Jun 09, 2016 5:12 pm Output vs efficiency would be pretty easy with something like a gas heater for instance. A smallish gas heater that has an output of 20mj at 70% efficiency would be preferable to a larger heater that can output 25MJ at 50% efficiency. Sure the larger one would be better if you have a big house but your energy bills would reflect that. A wood heater or fire - not so easy because so much of the equation probably comes down to what type of wood you are going to burn, how well it is seasoned etc. The peak output of 19kw for the Masport r5000 above would involve having the damper fully opened, as much dry hardwood as possible in the firebox and blazing like hell with the loungeroom door open to create as much updraft as possible. Hardly the optimum scenario for a cosy winter night but you would certainly heat the room. I know there is also a big difference in the types of flues as well. An inner flue that lets the smoke escape with an outer of S/Steel mesh will radiate a lot more heat back into the room rather than a double layer although what type you use is usually part of the manufacturers guidelines. If you scroll through this part of the forum there are other threads I remember seeing where efficiency and kw get a mention a few times too. I'm sure you could google and find an online calculator and punch in the fires output x the required temperature x the room size etc. Stewie Re: wood heaters - inbuilt. for large area 14Jun 10, 2016 3:58 pm i have basically decided that the bigger the firebox the better. So i am going the Masport i9000 as it seems to have the biggest firebox in the sense that it requires the largest hole in the wall to fit!! it is 760wx696hx565d in mm. it is just 55% efficient but has a high output. Efficiency is a secondary consideration but all wood heaters have a minimum efficiency of 55% anyway. the better ones are around 65%. not a huge difference. so i prefer the ability to heat a big space. Wood supply is not a problem as i have enough of that stuff to last a life time… big block with a lot of trees!!
