wood pellet stove and underfloor heating

[Philippe Schutt]

The homogenization flask, I guess that's also called a snap bottle. it costs around 200 € ht for example here: http://www.conecterm-68.fr/pdf/GrHy.pdf
it would give something like this:

1ere the mixer at the stove used to control the temp of the water back to be sure to avoid condensation. It may not be necessary, if we accept that the stove often turns to bottom. The other 2 used to establish the T ° departures circuits. They can be motorized and controlled by an electronic central or not. I would tend to say that the slab is set T ° to ensure the T ° at night, with the balance provided by the radiators, this because of the tremendous inertia of the slab makes management difficult day / night.

Not bad tone pattern !! For the first 3 way valve, it just takes the set once and for all and the stove runs a moderate pace at this time.
The pressure-breaking bottle can act as a "buffer" if there are radiators afterwards and therefore these act as a storage buffer at 60 ° C, a bit like the "CDSLO" person at the start of the forum .

and the "pressure breaker" bottle is much cheaper. . .

[casalanis]

but it takes too .. radiators. But it's worth it .
Good installation

By cons, it is poorly set location on your diagram, for stitching and return of floor heating and radiators must be on the ball

[Philippe Schutt]

yes, it would be better. and pay attention to what are the most central taps on the bottle.

[Philippe Schutt]

otherwise, as these stoves are in principle connected to existing boilers I use the following diagram when the general circulator rotates permanently:

when the stove is off, it's a dormant loop, and when the stove is lit is its pump that drives its loop, and it gives the main circuit is taken away by the mainstream.

If the general circulator does not run continuously, I think we must add a check valve on the common part loop / general. But I have not had the opportunity to test it, it's theoretical. it must be seen if my loop is still dormant in this case, I am afraid that the loss of load does cause a current. maybe put a check valve in the loop too, to create an equivalent loss of load? ...

OK for your schematic (one burner)

Can you add regulation (+ probes ...),

Thank you

here:


The management center is set to put the house at a basic T ° with the slab alone, say 18 °. in addition it defines the starting T ° of the water of the radiators.
a room thermostat circulates the water or not to extend the reference room to desired temp during the day. Radiators of other parts are balanced to, and those parts south are fitted with thermostatic valves. T ° thermostat night is set low to turn circuit at rest.

Hi Philip,

What a little bothers me is the 3 way valve (motorized so I assume therefore regulated high cost).

On another topic I had proposed to put, with possibility of manual bypass, the serial wood peole on the boiler return: The stove would be raiser in the boiler return temp.

Who is pro, what do you think?
