Guidelines on Setting a Manually Controlled, Four-Way Valve for CO Installation - Damian's Query

Hello

Since Saturday, I have had the pleasure of using a new CO installation and I have a problem with setting the four-headed valve and I would like to ask for such an explanation of this problem (manually controlled valve)

Thanks in advance for your help

Regards

The four-way valve regulates the return temperature to the furnace. It should be set in such a way that too cold water is not supplied. This also has an indirect effect on the temperature that goes to the radiators.
The setting depends on what kind of stove you have (what kind of opal). I would suggest checking the furnace manual what the temperature of the returning water should be.

Hello

The four-way valve in an installation with a solid fuel boiler (coal, wood) is used to increase the operating temperature of the boiler (better combustion, higher efficiency)
and at the same time keep the temperature of the radiators reasonable.


The idea of the construction of the valve - it looks more or less like in the picture:


By adjusting the diaphragm in the middle of the valve, you change the proportions of the amount of heat returning to the stove and thus delivered to the radiators. In the "0" position, you have a "closed" stove (a useful feature of this valve for the summer if you want to heat your hot water with a boiler connected in front of the valve and at the same time you do not heat the house).
However, in the "100" position there is a "no valve" system - all the heat from the furnace is sent to the radiators.


In the second picture, a typical connection diagram:


How to set it?
So that the stove was about 80 degrees C and in the rooms such a temperature as you want

What brand is this valve?

why the 80's??
you don't even know what kind of stove it is, and you know what chimney and other losses are??
what do you think is the working temp of the boiler

The boiler is a Ling Combi from Klimosz. After the first days of use, I can't say much about it yet, but I have a question if it makes sense to buy an actuator to control the valve and whether turning on the so-called weather forecast makes any sense?

Hello!
A four-way or three-way valve is used to ensure that the temperature of the water returning to the boiler never drops below 65°C. As the temperature of the water returning to the boiler increases, the amount of tar and acids formed decreases = longer boiler life. , i.e. water vapor settles on the walls of the boiler. Adding sulphurized coal to it
(often on sale) comes out a simple equation for weak sulfuric acid, not to mention acetates from wet wood. Above 65°C steam does not settle on the walls of the boiler and sulfur dioxide does not
with what to react. There is still a chimney, but that's another story

so I have to set the boiler to 65 degrees?

as for the valve, I have already figured out how to set it depending on the needs and I have to buy an actuator for it so that the boiler controller controls it itself ...
