wood pellet stove and underfloor heating

[Philippe Schutt]

but it is

The valve is manual, and the return is heated

[Christophe]

Uh Objection: it is not pure series but a "mixture" between the 2 ... to have the series it would be necessary to remove the blue segment which touches the hot return of the stove and the purple arrival on the boiler ...

Ok for the manual valve, so you might as well put 2 or 3 ball valves 10 times cheaper than a 3-way valve ... am I wrong?

[Philippe Schutt]

the segment you want to turn prevents water from circulating in the stove when it is stopped. This is necessary otherwise it does not restart the resistance (after a stop), believing that there is already a flame. it is possible that this is an edilkamin peculiarity.
yes, you can put ball valves, in fact I put more, to isolate the circuits. Why make it simple when you can make it complicated ?
Let's say that with a V3V we immediately see who is doing what, and otherwise we have to be more imaginative

I dropped the radiators upstairs (I'll put electric to keep costs down at first).
I had another heating engineer and asked him to make an estimate according to the diagram with stove alone.
On the other hand he announced to me a balloon of more than 500 liters, because according to him the stove regulates in all or nothing.
What do you think ?

I think that: thermal buffer calculation for wood-fired boiler

[Christophe]

the segment you want to turn prevents water from circulating in the stove when it is stopped.

Ok so this is a bypass without valve so in your case I do not see what prevents the water from circulating in the boiler even when the stove is running ... So a certain% of cold water will not pass the stove and so it is in serial and parallel installation at the same time ... or so I understood nothing?

It is necessary otherwise it does not restart the resistance (after a stop), believing that there is already a flame. it is possible that this is a peculiarity edilkamin.

Mmmm stopped during the heating period you mean? So if I understand correctly: the regulation on the ignition of the edilkamin is done on the T ° of the water (whose return would be too hot ??) and not, as on the oil burner, with an optical or ion cell ?

Let's say that with a V3V we immediately see who is doing what, and otherwise we have to be more imaginative

Yes for the plans you're right ... a V3V is much more explicit!

How does the ECOIDRO regulate in relation to the buffer tank?

[Philippe Schutt]

The ECOIDRO regulates according to the T ° of the water, between 3 powers, that is to say 3kw, 8kw and 11kw. a difference in T ° is fixed between the different levels (2 ° of origin).
So, as soon as it is cold enough to need 3kw to keep the temperature of the house, there is no need to have a buffer tank. In the mid-season, operating ranges are programmed, for example in the morning and in the evening, cut off at night and during the day. the slab's inertia does the rest, as well as 500 liters of water, in fact it replaces the balloon.

How much does the Ecoidro consume in 3 KW?
And do you have an ecodiro manual?

[Philippe Schutt]

at 3kw it takes 0.7 kg / hour.
Yes, I have the instructions, the file is 5MB
