Woodburner...

Last one I promise!

 

This is the Aduro, very efficient with plenty of glass, but the Rumford is the better experience, sitting a gazing at the dancing flames!

You can see my rather crude flue going to the old soot door

Well , last still photo!

Here are the videos 
The moon is bright and it has turned very cold outside, not in here though

The temperature on the Rumford is about 500 degrees and it has only been lit for about ten minutes and the Aarrow Stratford is about half that and has been lit all day but it is heating the water, on the other hand I would have expected the glass on the door to be a bit hotter

I have had this problem before putting a video directly on a thread.  Some can see it and some cannot

i usually have to put them on YouTube 

 

Anyway this is the Rumford after an hour an a half with no wood added

Just been on the roof and the temperature of the chimney pot is 7 degrees, so the efficiency of the Rumford is 500/7 x 100 or about 7000%.  I am only following the science just like Boris and I am sure it is just as accurate!

Nope . Just the stop start of the vid but no clip .

Would that not be 7/500 = 0.014 x 100 = 1.4

 

So 100 - 1.4 = 98.6%

 

Mind you TEMPERATURE is entirely different to heat.. Think of this, to heat the surface of a material with a very low specific heat capacity that was a good insulator to 500 degrees, would take very little heat, but to warm up the entire brickwork of your house to 7 degrees [from nothing] would take an awful lot of heat [for not a lot of temperature change]

 

Still, beats the heck out of having an insulated flue and having 500 degree flue gasses, [and a toasty warm sky!]

Maths was never my strong point, but like Boris

Can you see the videos and if so can you explain why Stubby cannot see them?

Here is the Rumford after two hours with nothing added
