wood pellet stove and underfloor heating

[jean63]

Hello,

To answer your questions, I would say you need a bottle of homogenization since you 2 types of diffusers (radiators + PC).
The bottle serves as a buffer, a recuperator of deposits.
Installing Jean63 which seems good might suit you.

We must not forget the power outage, your stove will not stop as a boiler, you will have to remove heat from it!

hi fc89,

That's exactly what I thought was missing, but there are only floor heating specialists who know. I even recently learned its function thanks to you fc89, after 20 years of operation. It's true that it works well and it decants well too. I have to empty it in the spring

And if I do not put radiator at first, what schema should I adopt?

[fc89]

Hello,

As I already proposed to you take the scheme of Jean63.
The bottle of homogenistaion will be twice as useful if you do not put radiator.
It will serve as a heat buffer to a highly variable heat source, and the regulation of the floor will tap into its sandstone.

Another question :

All the traditional heating companies (heat pump, boilers ..) argue the problem of the low autonomy of the stove. And if I mount a hopper (mini-silo 50Kg) above the stove to increase the capacity of the latter

Thank you

Hi,

But everything is possible!

Of course !!!

I made the same system at home:
And it is frankly given your heating floor! Your plumber is nice, and I think seriously considering your honest quote.
The cost of mine posed by myself and brand REHAU: 3000 € ttc for 120 m2 = 25 € ttc, and yours: 2667 ttc for 66 m2 = 40 €. at home it is a little more if I would have asked by a guy like 75 € m2 and a liquid chappe 25 or 35 €.
But it is true that there is a bit of work even, like mine with good advice: 120 m2 in six full day of work.
For the price of the ecoidro it is corect too, and it is the minimum price that you will find everywhere except the most expensive. . .
It must be an approved company-reseller of edilkamin, it remains honest in general As in palazzetti, finally on the side of my home anyway.

On the other hand, the mixing bottle is obligatorily obligatory if you do not have a radiator, and of size like 150 liter.

After there are some adjustments to make.

You need a mixing valve, and other small gadgets.

But hey, if you are a competent installer, he will be able to do all that, and he already has the "fair price in his favor".

For risk of overheating on power cut, there is no problem because the stove cash well a slight rise in temperature: mine stops for power cut, then re-ignition in the 5 mn the water temperature of the stove summer go of 60 ° ca 72 ° c. And if there is overpressure there is a mechanical discharge valve that sends all the water to the sewer. No problem.

For the additional granule reserve I thought it must be possible too and tinkered itself (the guarantee?), But hey it's not very complicated to put a bag in a tank, we put gasoline all the weeks in our cars ...

It must clear a little while radiating, it would be good to installed in a useful place.

In any case, all this can work very well if you had enough isolated.

I forgot to say on the price floor heating: I have insulating plates of shit, ie 3 kind cm thick which is carelessly insufisant. We must add at least 6 € / m2 for plates of good quality.

OK for the mix bottle and the V3V, however do you have references and prices

Thank you

Thank you

The V3V piloted with a clock and temperature probes ext + heating floor start and return PC (more room sensor: I do not have any) ...... it's very expensive mine date 20 years and I had a problem, they asked me 8000 francs. Finally, it was repaired for 1000 francs (the regulation part) and the valve 3V blocked 2 years ago: I disassembled it myself, cleaned and it looks like new ..

The homogenization flask is GIANOLA brand. The current model is presented on their website. Mine is 50 liters: its price of 1985 does not mean anything today. Inquire at a seller.

The floor heating is a good system, the disadvantage is the inertia, it is necessary to wait 2 hours before really see the temperature rise, but it is not annoying because like today in my MOB, with 6 ° From the north, there is 20 ° in the boiler house, which has been extinguished since last night. I'm not going to re-light it, I think, if the temperate ext does not go down.

For my part, the monobloc regulation ESBE 90C with external probe and probe departure: 750 € approximately (I had a price the top because in fact I think it costs 1000 €), there are 2 months. It has the possibility of receiving a room sensor.
For the bottle of mixture account about 500 euros, but by adding a little, kind 300 € more you can have in addition the domestic hot water with a balloon with two exchanger.
