    Wow this is great! I will likely have many questions, but for now...
    1. Can you describe your P channel system? What is it made of, what size and number of holes (and ratio of air coming through it versus the grate and door). Where does it draw its air from? Does it come through the top of the door? I don't see a hole in the brick veneer.
    2. I've also been trying to figure out a boiler system. Your pump doesn't run continuously? It takes a minute for the water in the heat exchanger to heat up before it kicks on again? Also, I didn't think of the condensation... this is from the wood water vapor condensing on the cool pipes? I have also been looking at the lopez labs boiler, why do they not address condensation?
    Thank you!

    • @nimela4937
      @nimela4937  4 роки тому

      1. P-channel made out of square 40x40mm pipe, 2 pieces, draws air in from the room, comes out the top of the door.
      Sizes are as follows: P-channel into door 80x25mm, primary air in door 120x50mm. We also have an ash cleanout door that we sometimes leave open for extra air intake (depends on the type and amount of wood in box).
      2. Pump is driven by a thermostat, pump runs more frequently when the fire is burning and continues running (for less and less time) for about 24 hours after fire is out.
      I have 2 trays on either side of the main heater core to collect condensation - that comes out of the house through a copper pipe. There isn't very much, just a little trickle. Depends on the temperature I set on the thermostat.

    I can not figure out exactly what kind of ceramics you used for the heat riser construction but it does not look refractory.
    If it is I'd love to know where did manage to buy it.
    I'd have some questions
    - What is the power (heat exchange surface) of the heat exchanger
    - what is the volume of the buffer tank
    - where was the container for collecting the condensate placed?
    - Have you installed any beam over the wall whole

    • @nimela4937
      @nimela4937  6 років тому

      The heat riser is sold as refractory (although it is of very poor quality), did not have any problems with it so far. Bought from: www.heliossa.ro/materiale_refractare.html
      Have also worked with other brands that are much better, thinner and way more resistant. These I had on hand at that time.
      1. The power considering amount of thermal power generated by burning wood for 1hr should be about 17kW (considering 1kg air dried wood=3.7kWh of energy). Mean power about 4kW (batchrocket.eu/en/building#size).
      2. Heat exchanger is made out of copper tubing, outside diameter = 22mm, about 50m total length, 10kW, considering 2.8kW/sq m
      3. I do not have a buffer tank hooked to the heater, the buffer part is provided by the heated masonry. Water pump runs for a while, heat exchangers fill with cold water from the system, they are heater again by the hot bricks, pump starts.
      4. There are 2 containers for condensate made out of stainless steel pipe cut in half placed on the bottom of the bell, under the heat exchangers. Copper pipe is welded to the containers and is run outside. I guess a few liters of condensate drip out from every fire. Pump thermostat is set at ~60 degrees C.
      5. There is no beam over the wall hole, I just filled the part on top of the heater with insulation (glass wool). The white part you see in the video is just a sort of drywall that is held in place at the sides. The top of the heater does not heat up at all as there are a few layers of insulation inside as well.

    Many detail missing but, interesting build.
    Planning in making a free-standing batch rocket in the Van Den Berg style, with an altered riser of my own design... which can be easily changed to Peter's, should it not perform.
    The "p-channel".... is that secondary air?
    Would appreciate seeing how you heat your water for the baseboards.... even drawings would suffice.
    Nice job. Thanks for the inspiration.

    • @nimela4937
      @nimela4937  6 років тому +2

      P-channel is secondary air, correct.
      The water is heated by the heat exchangers placed left and right inside the second layer of brick, the outer 'bell'. Check this link out for reference: heatkit.com/html/lopezs.htm
      The difference is I have 2 and they are made of 25mm (1 inch) copper pipe mounted in the Tichelmann schema.

    La final, in faza de jar, trageti jarul in fata, deasupra gratarului? Isteata inovatie, n-am mai vazut-o la altii. Ar merita semnalata lui van den Berg, pentru beneficiul multora. Banuiesc ca reduce semnificativ faza finala, inainte de a inchide cosul...

    • @nimela4937
      @nimela4937  6 років тому +1

      Cenusa o trag prin gratar inainte sa fac un nou foc, asa ma scuteste de a trebui sa o scot de fiecare data afara. In functie de marimea cenusarului se poate scoate cenusa destul de rar. Mai are avantajul ca pot deschide usa de la cenusar cand aprind focul ( e nevoie de ceva mai mult oxigen in momentul respectiv). Cosul si deschiderile din usa le inchid in momentul in care ramane doar jar in focar.

    • @nimela4937
      @nimela4937  4 роки тому +2

      Intre timp, dupa 2 ani de exploatare gratarul s-a curbat si in final s-a spart de la temperatura prea mare in zona respectiva. Teava pentru aer secundar e inca in conditii bune, probabil pentru ca e racita de aerul care il trage de afara.

    Very nice.What are those cylindrical pieces you used for the riser and where did you get them?

    • @nimela4937
      @nimela4937  7 років тому

      They are refractory brick cylinders. About 8 inches (200mm) inside diameter. Wall thickness is about 1 inch(25mm). Got them from a store here in Romania. They're commonly used for building the inside of chimneys. As far as I know the smaller the wall thickness the better (will get up to temp faster).

      An ideal riser would be made entirely out of insulation, so it loses no time (or energy) with heating the wall. As far as I know Peter van den Berg was experimenting with such a riser at one point.

    • @nimela4937

      We currently have 5 radiators hooked up to it with a total thermal power of ~3.3kW. Some spaces are heated by the brick heater itself. The house is 115 sq meters. We also have a 100L water heater that is hooked up to the heat exchangers.

If not does the large pipe I saw make flow speed increase or decrease..2nd?, the 5radiators, are they fed in series or parallel from source..great brick work great door work..last question that's a large space, how many times box loaded during the day starting from Sun rise..luved those clay chimney blocks, such a smart block

    WHY THE SLOT IN THE BASE OF THE CHIMNEY ?????????WHY THE OPENING UNDER THE V FORMATION ????

    • @nimela4937
      @nimela4937  6 років тому

      There are 2 exits for hot air out of the heater:
      1. At the base, the primary exit
      2. At the top, a smaller, secondary exit, that you open only when heater/chimney is cold.
      This way hot air is forced to stay at top and only exists when it cools. Look up
      'System of Free Gas Movement', Kuznetsov and/or bell principle.
      Opening at base of V is for ash pit - it's more convenient to take out ash once a week than every day.

      Focul il facem o data pe zi, aproximativ 2 galeti de 20L de lemne, una pentru pornire, esenta moale si mai subtiri, a 2-a mai groase.

Va multumesc pentru raspuns.....sa -o folositi sanatos ....am vrut sa stiu consumul pt ca o sa -mi fac si eu una asemanatoare...stiu ca asemenea tipuri de sobe au arderea curata si un randament f bun ,cu toate ca sint multe opinii contra ..... va multumesc din nou si multe sezoane fara probleme 👍

    • @nimela4937
      @nimela4937  6 років тому

      Sunt cateva aspecte care trebuie luate in considerare:
      1. Randamentul arderii, care e destul de bun cu sistem batch rocket al lui Peter van den Berg. De asemenea ajunge rapid la randament maxim, trebuie alimentat mai rar (comparativ cu sistemul rocket clasic) si asigura o ardere curata.
      2. Mentinerea caldurii, asigurata de sistemul clopot.
      3. Intretinere putina.
      In afara de aspecte estetice, legate de constructie, pret, disponibilate, nu vad ce opinii contra ar putea exista.
      PS: Am luat in considerare si construirea sobei afara, doar ca era mai greu sa folosim cuptorul :).
