Hi, it's rated at 16.2kW max output.

This fire is way bigger than the Rais Bionic. The fan is not required to make it operate - it merely assists radiant heating by providing a boost with convection to throw the heat further away - an excellent feature for heating the house extremely quickly straight after lighting the fire. The Masport functions perfectly well without the fan - I've used it several times during power cuts and there's virtually no difference in heat output.

It's engineering wizardry at its best. The basic idea is to direct the smoke generated in the upper chamber down through the base of the fire to the lower chamber, where a secondary burn takes place. This essentially incinerates the smoke particles a second time and has two benefits - it creates additional heat, and there are less unburnt particles escaping up the chimney ( and therefore fewer emissions than a standard burner). When my fire is running, there is no visible smoke coming out of the chimney, and almost all the wood fuel is completely burned rather than creating ash. I only have to empty my ash pan about once every 3 months or so.

This was one of the very first models of ultra low emission burners. One of the downsides of these early ULEBs is the need to add fuel more often than a conventional log burner. One of the difficulties is that the more fuel you add at once, the more the fire will rage - it won't really burn longer, it just burns hotter. Once my burner is up to temperature, I put about 1 log per hour on. It will maybe burn for 75-90 minutes at most before it dies out. New ULEB designs have come on the market in the past year or two that allow you to bank the fire down to burn overnight, which is obviously more convenient. The key to getting the most out of the early designs is to have a well insulated house. In winter I run my fire from around 5pm to 9pm and then let it die out. The insulation in my house is sufficient to retain the warmth from my fire right through until the next morning.

No, by pulling the damper lever, this redirects the exhaust gasses down to the secondary chamber (where they are ignited for secondary gasification). The remaining exhaust then goes towards the rear and up the back of the unit where it rejoins the main flue. This video demonstrates the underlying principle: czcams.com/video/BDy9gutoK2c/video.html

This fire cost me around NZ$7500 back in 2016 when they were first released. I believe the price has come down over time and you can get a similar model for around NZ$3500 now. Back when I bought mine they were a very new concept and there weren't many models to choose from, but now there are a number of models available in New Zealand.

Das ist das holzvergaserprinzip.

I don't know much about coal - it's been outlawed for domestic use in my city for as long as I can remember (and I'm 45). On the west coast of New Zealand many people still burn coal as there are many coal mines over there and so a plentiful supply, but I think local authorities are trying to wean people off coal. With regard to this model burner, I have been told that coal would burn far too hot and would cause damage to the unit as a result.

It depends on what country you are in. They are readily available in New Zealand where ULEB burners are mandatory for new build housing in many urban jurisdictions but I am not sure about other countries sorry.

I'm not sure sorry. They are readily available in New Zealand where ULEB burners are mandatory for new build housing in many urban jurisdictions but I am not sure about other countries. I tried googling ultra low emission fires in the UK but didn't come up with anything so perhaps they are not available there yet.

They are 31x10.5 R15s. I believe that's the standard size for some US market 4Runners, but the Japanese Hilux Surfs came with a smaller size from the factory (235/70 R15 I think). I fitted the larger 31" mud terrains when I was going offroad a lot. The brand is Firestone ATX23. Common here in New Zealand but not sure about overseas (I think they are made here).

@@wheelbarrow01 Thanks! I will look into the firestones more.

I'm not too sure sorry - I don't know if these are commercially available in Canada or not. You could try googling Ultra Low Emission Burners and see what comes up for your area.

Yes the fan has two speeds and it activates automatically when the fire reaches a set temperature. The low speed is best for continuous use as it's very quiet. The high speed is very loud however it blasts the room with hot air to heat the room very quickly. I hardly ever have to clear the ash - due to the very high levels of combustion and the secondary burn chanmber, very little ash is produced. In the middle of winter when I'm using the fire for several hours every night, I tend to only empty the ash once a month or so.

Blödsinn was du sagst. Besserer nutzen vom holz. Höherer Wirkungsgrad.

I used to have a standard log burner at my old house and have found it uses around the same amount of wood. In fact I have found that because this fire produces such a huge volume of heat, I tend to let it burn out earlier in the evening, thus actually saving me wood. I fill my woodshed for around $200 and it lasts the 6 months of the year that I need it to. Prior to installing this fire I was using a wall mounted heat pump, but that was costing me $500 per month in electricity to run. Since installing this fire, my winter power bill is less than $100 per month + around $35 a month for wood averaged out.

Over time the bottom glass has become harder to clean. Now I only do it about once a year and don't worry too much about it.

Yes, my sister in law lives on a farm and seems to get dozens of free community/rural/farming papers delivered each month which she kindly delivers to me every few months, so I haven't bought firelighters in years!

Lucy Harris - the fan has high and low speed settings. It's pretty loud on the high setting but very quiet on low - you pretty much can't hear it on the low setting at all, especially with the tv on. I only use the high setting if I want to heat the house quickly, say when I get home from work on a freezing day. I really love it though - it heats the house so much better than my heat pump ever did. I bought a heat transfer kit at the same time but haven't installed that yet, but that will help balance the house temperature. At the moment it gets a bit too hot in the lounge but my house is quite long so I need to push the heat to the other end. I hope that helps 😁

Michael Poole - Sorry for the late reply. Initially it did seem to burn a lot of wood but I was using a mixture of pine logs and pine timber offcuts - which I now don't recommend. I now use pine kindling just to start it, then I switch to oregon once it's hot, with a bit of pine here and there to keep up a decent ember base. It now seems to burn slower as a result. I pretty much used the fire every night for 5 months last winter, probably for at least 7 hours a night, and I think I went through about 4-5 cubic metres of wood. That is a similar amount to my previous non LEB fire. You can't bank it up to slow burn all night as it's not designed to do that. Last year I found that the house would quickly get cold after I let the fire burn out so I tended to burn it till around midnight. I have since insulated the walls of my 1960s house and it has made a massive difference. I now let it burn out around 8 or 9pm and the house remains warm for many hours.. The result is that I expect to use less wood this year compared to last due to less burning hours per night. I started with 3 cubic metres about 2 months ago and have burned less than half a cube so far. The moral of the story is that in a well insulated house, and with the right fuel, you should burn a lot less wood. I hope that helps 😁
