SALUS Controls - boiler / furnace control - set with radiators and many thermostats
We are continuing our journey with Salus heating and expanding the control in my parents' apartment, where in the tenement house everyone heats with their own stove. Heating is provided by wall heaters and the boiler is dual-function, i.e. it also heats the tap water.
How to connect to a Salus stove and how does it all work in the basic system? I describe here: SALUS Controls - boiler / furnace control - a set with one thermostat, and in this article I will focus only on extending this solution.
Why Salus? I answer in this article: Salus - new blog section!
We tested Salus in the tenement house at a massacrely fluctuating temperature (parallel to the apartment): 20 degrees during the day, a day later below five and snow, and frost at night - the windows are "new" plastic. The tenement house is made of bricks (very thick walls). The apartment is located with windows facing north and south. one of the rooms is almost directly above the entrance gate. The staircase is not insulated and there is an expansion joint on the other side. So it's cold on all sides;)
And now the second season has started when the test system is installed and I have to tell you, your parents are very happy!
What does this solution give us?
When we have a thermostat in each room that can independently activate the boiler / stove and heat the room? Finally, we do not have heat, only where we have the main thermostat from the stove, but the temperature is constant throughout the apartment. It does not matter that you just took a shower in the bathroom (the radiator automatically turned off).
It does not matter that we cook in the kitchen and it is very hot, then we quickly open the window to cool down a little. Two things work here - the window is open, the information is off! And in the other rooms in the second part of the apartment we have heating all the time and we do not freeze! This is a mega real thing.
How did it work before? One thermostat - you had to constantly maneuver where it should stand (or constantly change the temperature) - because it was either cold in some room or too hot, because all of them had open circuits or were turned off manually, and now? Everything happens automatically!
Do you need three all at once?
Here I must point out that we have pre-installed the radiator heads in 4 rooms, and the rest? Keeps running on fully open heads, does that mess something up? And yes and no;) If even one thermostat sends a signal that it is too cold in the room, the stove will start to heat up. It will stop like all of them, but all of them will send a signal that it is not necessary anymore - that is, they turned their heads.
Since we installed the heads in 4 rooms at the beginning, we will overheat the room all the time in those where there is no room, because the radiators will heat up with all their power - unless we twist them a little - this way, we do not have to spend the entire amount on the installation right away and see how it breaks down and I'll show you this example here too.
