Pellet Boiler Kostrzewa TWIN BIO LUXURY 16kW, Floor Heating & AFRISO ATM366 Valve Integration

Hello

I am asking for help and a diagram of the best solution.
I now have a floor heating with AFRISO ATM366 thermostatic valve mixing valve with grundfos upm3 pump, bypass.
In the house there will be only a 12 floor circulator of approx. 1050m pipe, 16 house approx. 200m2 with an attic.

It will be supplied from the kiln pellet Kostrzewa TWIN BIO LUXURY 16 kw
In addition, the system is to be a hot water tank of approx. 250L

I would like to be able to heat independently hot water, but also that it would be possible to put a floor heating floor back on.
I wonder how to do it with the 3d or 4d valve.


I do not know the installation completely so please be understanding. The installer will probably be connected, but I would like to be able to confront his vision with your solutions.

Here you have the manufacturer's scheme:

If you only have a floor heating machine, you will need to invest in a buffer - as in the diagram - and connect the hot water tank to it and supply it to the floor divider.

I do not know what you mean by:
"but also that it would be possible to put a floor-tile on the return from the hot water"
You could develop this issue.

Well, just the installation for now I'm going to build without a buffer (cost limit), possibly expand it in the future (quite thick screed mixokreta think that it will be a sufficient heat buffer, I want to try it first) or in this case, just cut it out and scheme can it look like this? Of course, instead of this SYR5067 chip, I want to use open layout. And this "automatic return protection valve" is a 3D valve simply? Is it better to use 4D with an actuator. The boiler has a control function.

"but also that it would be possible to put a floor-tile on the return from the hot water"

I mean, is it possible to do this and whether it is a good solution that the floor heating power supply is connected to the return of the domestic hot water boiler. Of course, this would be realized when they operate, and what about hot water and in the summer it would be possible to disconnect and heat hot water.

What do you think about the layout below

or maybe a solution with a hydraulic clutch?

This is not done. This is why there are separate pumps for central heating and for charging the hot utility water tank so that they can walk separately. In winter, both systems work, and in the summer only one (CWU).

In my opinion, without a buffer, it will be very difficult to maintain the combustion process so that it is economical. The flooring has a lot of inertia, but it can not act as a buffer because you will have very large temperature fluctuations.

See on what parameters this boiler works with the highest efficiency?
For this you need a buffer - because you will not push such a temperature in the floor heating. In addition, your manifold already with a built-in mixing valve (thermostatic) will also make it difficult. If you do not set up a buffer now (when the best moment is) then later it will be more expensive, much more expensive and harder (less space, etc.)

And what buffer for this installation would be the best? How much capacity? Do you need coils?

And what the cost will be different now from later because I do not understand too much ???

Buffer minimum 500 l capacity - preferably ~ 800-1000 l.
Coils are not needed.

The higher cost of subsequent assembly will be due to more work - cutting the installation, draining the water, fitting the buffer, etc. Now it is always easier to fit in and connect.

Take a look at the attached diagram or will it work ok? For a max 300 L buffer, I can manage to get out as it is not a hydraulic clutch. If in this installation you can save on something, please info. Every zloty counts.

Schematic vg.
The clutch will not give you anything - it does not take up any amount of heat - there must be a buffer and that's as much as possible. Possibly a combination container - a tank in the tank. You have a buffer tank and a hot water tank in one, for example Biawar BUZ 750/300.

Unfortunately, the price is overwhelming. I have quick questions about the buffer, maybe a little off topic. Can the buffer be horizontal and hang around the ceiling ?? (on the all-way there are old horizontal viessmans). Possibly black-colored tanks will give it up? How with their endurance? I have quite a small boiler room and it gets tight there.

If I do not have to use this 80kw clutch and see what will be ... The pellet stoves are quite well controlled and this can help.

One more question about the open tank. How old is it right to go to the pipes? Because I saw somewhere that one pipe can be grasped and I see that on some schemes there are 3 pipes. What are the others and what is necessary? I know that the warm water entering from the top is to be made of copper tube 28. The rest does not have to be so expensive?

Old topic, but I'm also thinking about the Pellet stove and floor. I am puzzled by the symbol of the crossed out (one line) rectangle in the diagram. Could someone explain it?

I guess it's a check valve. But this dot in him changes something? Is this a direction of flow (assembly)?

It is a symbol of a check valve - you can say a flap - you need to be careful with the installation in accordance with the flow.

Thank you very much. I thought so, but I wasn't sure. This connection scheme of the boiler from Kostrzewo seems to be well thought out. I think that's exactly how I will do it at home. I would have three more questions if I could:

1. There behind the heat buffer, on the right - is a boiler with a coil, right? I understand this correctly?
2. Expansion vessels are expansion and the whole works in a closed system?
3. SYR valve - the one behind the boiler - has a drain to the sewage system? Is there any vessel that is supposed to collect this water?

1. Yes - there is a boiler with a coil. But a better solution are standing tanks / exchangers with a large coil for gas or jacketed boilers.
2. Yes - there are diaphragm vessels and the system is closed. You have to remember that the boiler should have in the papers that it is suitable for closed systems and for this you need to properly protect it, among others, you can use a cooling valve.
3. Water from the cooling valve goes to the sewage system and not to the vessel (it would have to be very large). In addition, the use of a cooling valve has its own requirements: water from a mains water supply and not from a well with a hydrophore - the point is that if there is no electricity, the water will flow.
