Hello everyone,
I suppose this will be said a lot, but it's really a pleasure to meet partners like you who bring their experience to this kind of projects... one feels as comfortable as near a rocket stove...
In a few months we hope to be able to build our new house and, after attending a workshop on batchrockets last year, the idea is that the heating will come 100% from a stove according to Peter's criteria at batchrocket.eu/.
I still have some very general doubts, and I'm a little curious as to whether the intuitive design we've come up with is going in the right direction.
There was no discussion at the workshop about the possibility of heating water to include a floor heating circuit and I have not found much information about this either.
I'll put below the data and images that I'm handling for now, any comment, suggestion or warning signal will be very welcome.
Total area to be heated: 390 m3 ( 240 m3 on lower floor // 150 m3 on upper floor )
Insulation factor: 0.8 ( Thermo-clay blocks + backing : 39 cm )
Temperature difference: 12ºC ( 20º -8º )
Q = G*V*DT = 3.744 _ 3,7 Kw
First important decision: We thought that going to a 200 mm tube size would be the best way to make sure we don't fall short, we don't have space problems, and we have a couple of areas somewhat far from the cooker to which we could perhaps add underfloor heating (rectangles marked as 1 and 2)
Heater Riser Dimension: 200 mm
Box Dimensions
Width: ~300 mm
Height: ~440 mm
Depht: ~550 mm
In any case the idea is to have 2 bells, the first one on the lower level ( wrapping fire box, with an aprox. ISA: 5m2 ) and the second one on the first floor ( ISA: 3m2 )
Preliminary Total ISA: 8m2 _ Additionally it would include a small white oven in the first bell that is not yet drawn, plus the possible water heating coil that I suspect will greatly cool the air inside the bell.
I include in this post images of how the basic set would look like, with the 2 bells, the by pass to facilitate fire ignition and the connection pipes between bells (the radiant areas are in semi-transparent orange, the isolated ones in white or yellow.
(I hope you understand well with these images... of course it is much easier directly in sketchUp XD)
My doubts at this level are:
Do you see this as minimally feasible or do we have to work on alternative designs?
What do you think of the general dimensioning for the house and the distribution by hoods?
Do any of you have experience installing underfloor heating heated by this type of cooker? a friend who worked in this sector years ago told me that as there are only 2 "small" circuits (20 + 15 m2) there would be no need for a tank but simply a couple of thermostats, water pumps and safety valves. is this a crazy idea or can we work on it?
All comments are welcome, it is true that I have no experience in these things but I am not afraid of complex projects if the potential is good, and I think in this case it is.
Thank you very much in advance, and a great year for all.
