Buffer ball mixing valve

[Yacha]

one more question what is the difference between a 3-way valve and a 4-way valve?

Hello

plug in the piping to incorporate the probe

A waterproof housing must be provided for the probe
It's called a glove finger

your editing you prefer heating and after the surplus and stored in the balloon, in my case I already heat the balloon and after the heating

It all depends on the speed of the circulators
I think your montage has several taps on the ball
The principle is the same, but everything must go through the buffer, the stratification ensures that the hot water from the start does not mix too much with the cold water below (to be checked)
The boiler circulator must push more than that of the heating circuit, especially since you have a recycling loop

have a motorized regulator doc

You have to look a little on the net for "3-way valve regulation" or "water-dependent regulation" etc ...

difference between a 3-way valve and a 4-way valve

I explained it at the beginning
The 4-way is like the 3-way with 1 additional way for a mixed return to the boiler (oil, wood or gas)
In your case, the 4th channel is not necessary if you have a thermovar that performs this function

I have it without v3V

Hello

Another link on the principle of mixing and regulation

Bonsoir

As its name indicates, the thermostatic valve ensures the mixture hot / cold water to obtain the temperature setpoint output. Its operation is purely mechanical and does not require external energy.

3 Channel Valve Temperature Control works with a setpoint temperature, probe, motor and microprocessor to manage everything.
Here is an example of simple regulation, but which already costs more than 300 euros (fits on a mixing valve 3 or 4 channels)



The more advanced regulations take into account the outside temperature, the heating curve, etc.

These regulations do not depend on the heating mode: wood, gas, oil, buffer or not

hello and how do you drive the servo motor?
with a room thermostat it can do it?

Hello

The model that I gave as an example is only an automaton which adjusts the position of the valve to reach the right temperature on the probe.
This temperature is modified by manually adjusting the adjustment potentiometer.
The controls which adjust the heating flow temperature according to the outside temperature are more sophisticated and much more expensive.

In your case, the thermostat should simply control the start / stop of the circulator. You can start by making a manual adjustment of the 3-way valve and see if it's enough.

ok I ask for it because I saw on advertisements of 3-way valves controlled by room thermostat

Hello
I am currently redoing my installation, and I was telling myself that afterwards I was going to add a heat pump can you give me a diagram to couple my boiler to a heat pump

Hello,
why a CAP? How are you going to pump hot air in the middle of winter when it's -5 ° C ??

[Yacha]

well when it's -5c ° I turn with the pellet boiler!
the cap is for mid season
