🔥 How to choose an elektródový kotol a not make a mistake?
⚙️ An electric kotol is heart your vykurovanie system.
But how do you know which one is right pre your home, flat alebo business?
⚡ Single phase alebo three phase?
📏 What capacity?
🎛️ What kind ovládanie is it s?
💧 What does it work s - underfloor vykurovanie, radiators, solar panels?
This guide will help you understand everything step-by-step, s examples, diagrams a hints.
No confusion - just clear answers a straightforward advice.
🔌 Step One: What type electrical connection do you have pri home?
To choose the right elektródový kotol, first determine what kind of power supply your home has.
What is the voltage in your home❓
230V
400V
🧩 All kotol models by voltage a výkon range
Before choosing a kotol model, it's useful do estimate how much vykurovanie výkon your space needs.
🏠 As a general rule: one kilowatt (1 kW) kotol výkon covers about fifteen square meters (15 m²) moderately insulated space, which is typically sufficient pre most European climates.
📏 Example:
-
45 m² → approx. 3 kW
-
90 m² → approx. 6 kW
-
150 m² → approx. 10 kW
This helps match kotol’s výkon do your actual vykurovanie needs
You can now use chart below do find right kotol based na your available voltage a estimated výkon.
diagram below shows all available GAZDA a GALAN kotol models categorized by výkon supply.
➖ Dotted lines represent kotly that, while designed pre trojfázový connection, can also be used s jednofázový setups — typically up do 9 kW.
Technically, any trojfázový elektródový kotol can be connected do a 230 V supply. However, v practice this is only done s models up do 9 kW, because higher-výkon units often exceed limits jednofázový electrical infrastructure.
a by way, flexibility works both ways. Just like you can connect some trojfázový kotly do a jednofázový system (up do 9 kW), you can also connect three jednofázový kotly do a trojfázový network. This allows you do distribute load evenly across all phases — no need do boost neutral wire. Since phases never hit peak load pri same time. This setup is often used v cascade alebo parallel hydraulic connections.
🎛️ Step Two: What kind ovládanie do you prefer?

🔧 Adjusts vykurovanie based na water teplota v vykurovanie system.
✅ Turns kotol na a off based na user-set teplota vykurovanie fluid.
📦 Example product na our website:
comfort a efficiency your vykurovanie system depend na type termostat you use. Here are main options.
🧊 Basic controllers (non-Wi-Fi):
💬 We used do install those TP-16 controllers — but you know what? We completely switched do GAZDA G105. a here's why — it’s just got way more pros.
First — it has one simple vykurovanie mode. None that "cooling" mode alebo “intrval” mode. Honestly, that makes a huge difference! Second — you can easily connect an air termostat do G105, a it just works. No issues.
s TP-16, we were constantly getting calls: “It’s not vykurovanie”, “It’s broken”, seriously... a turns out, person just accidentally switched it do cooling mode alebo “window” mode, a kotol wouldn’t turn na. So there we were, explaining over Telefón pre half an hour how do switch it back. It got old real quick.
So yeah — we moved do GAZDA G105, a guess what? It’s been ages, a not a single call like that. It’s simple, clear, works like it should. Everyone’s happier — us a clients!
Programmable regulátor – water teplota
📅 Lets you schedule vykurovanie during day alebo week based na water teplota.
✅ Good pre homes s predictable routines.
📦 Example product:

💬 I wanted to say a few words about the TP16H too. This is our weekly termostat, unlike the staard one. I still keep these around, even have a couple lying in storage.
What can I say - it's basically a decent regulator, works as it should. Controls water temperature bez any special complications. There are tons of similar models on the market now, nothing extraordinary, but it's a reliable piece of equipment.
We worked s it for a long time bez any significant issues. The most important thing - you can program it for a whole week ahead, which some customers really appreciate.
By the way, we even put together a tutorial for it - both video a proper instructions. If you follow the link I posted just above, you'll see everything for yourself. It shows all the details: how to set it up a how to program it. Nothing complicated, really, you just need to figure it out once.
In short, it's a staard termostat, nothing fancy, but it gets the job done. If you need weekly programming - this is just the thing!
💬 About KROS 110 a KROS 325 thermostats:
Let me tell you something else — KROS 110 a KROS 325 thermostats are something special. Technically, they fall under “programmable water teplota” category, but v reality — they’re na a whole different level.
Their main feature isn’t just scheduling — it’s that they actually ovládanie výkon level elektródový kotol itself. That’s super rare when we talk about thermostats pre kotly! You manually set how much výkon kotol should run pri — which lets you adapt system do any kind water. Too much mineral content? Just reduce výkon — a everything runs smooth.
Yes, course, they can also run na a schedule — day, night, weekends, whatever you need. But real value is v that fine-tuned ovládanie, not just basic na/off switching.
If you’ve got an elektródový kotol — these thermostats are a perfect match.
Oh, a don’t forget jednofázový GAZDA GM 106 kotol. It already has a built-v regulátor based na KROS system — so it comes ready s integrated výkon ovládanie. Basically, it’s a monoblock: kotol a regulátor v one compact unit. Super convenient, especially if you want minimal wiring a maximum efficiency.
Standard regulátor – air teplota
🌡️ Measures a controls teplota v room.
✅ Maintains room teplota based na value set by user.
📦 Example product:

💬 Let me tell ya about those bimetallic air termostats real quick. These are like the simplest regulators you'll find - total basics!
So how they work - you just set your air temp, a inside there's these two metal plates made of different metals. When they heat up, they either connect or disconnect from each other, a that's the whole principle behind it. That's where the name "bimetallic" comes from, obviously.
Let's say you set it to 22°C, a it's got about a 1°C differential by default. So what happens? It'll switch off at 22° a then kick back on when it drops to 21°. Super simple stuff!
To be honest, we hardly ever used these ourselves. But hey, if someone needs a dead-simple solution that just works bez any bells a whistles, they're perfectly fine. Nothing fancy, just old-school reliable tech that's been around forever.
Cheap too, compared to all those digital models. Sometimes you just don't need all those extra features, you know? Just something that turns your heat on a off bez having to think about it!
Programmable regulátor – air teplota
📆 Full scheduling by air teplota v room.
✅ Great pre switching between day/night comfort levels.
📦 Example product:
Computherm Q7
💬 So the next one we've got is the Computherm Q7 termostat. It's basically just a regular air temperature regulator that runs on two batteries, I think. It was manufactured in Hungary for many years, a we used it too - installed it in parallel s the TP16 water termostat a s others as well.
Can't really say anything bad about this one either. Just a staard regulator s a nice big LCD display, which is actually pretty pleasant to use. Again, there are countless regulators like this around the world, especially s China pumping them out like nobody's business.
We found it reliable enough for everyday use. The large display makes it easy for customers to read the settings, which is always a plus, especially for older folks. Nothing fancy about it - just does what it's supposed to do bez any fuss.
So yeah, pretty basic stuff, but sometimes that's exactly what you need - something straightforward that just works!
📡 Wi-Fi controllers
Both air-based a water-based Wi-Fi thermostats can be integrated into a smart home system — no difference v functionality here. only distinction is how they measure teplota:
Wi-Fi termostat – air teplota
-
🌬️ Measures a regulates teplota inside your room. This is classic approach — controlling comfort based na what you feel.
-
Wi-Fi termostat – water teplota
💧 Measures a regulates teplota vykurovanie fluid inside your system. Indirectly affects room teplota, but gives precise ovládanie over kotol operation.
📲 Both types work via mobile apps, offer scheduling a remote ovládanie, a are plne kompatibilný s all GAZDA a GALAN kotly — especially effective when used s solar panels alebo smart energy setups.
Wi-Fi termostat – air teplota
🌬️ Measures a regulates teplota inside your room — classic a most intuitive way do ovládanie comfort.
🧰 Example: These are typical Wi-Fi thermostats that regulate air teplota. market is full such models, so this is just one example.
💬 Back v 2022 — especially before autumn — we actively installed Wi-Fi thermostats that controlled kotol based na air teplota v room. pri time, it was a real trend — even older generations were getting interested v managing their vykurovanie from a smartphone, setting schedules, checking temperatures, a so na.
We’ve added a few models do our site just as examples — ones we actually used. These days, we no longer install alebo recommend these thermostats, but pre reference, that’s what we were working s back then.
We picked a couple options that seemed reliable a easy do use — they’re shown v photos below. We installed them more than once, a they did their job.
That said, no system is perfect. These thermostats come s their quirks. First — accuracy. They only respond do air teplota v room where they’re installed, not whole house. So one room might be warm, another too cold — it’s not always ideal.
Second — connectivity. These systems have two parts: a base unit a a display unit. They communicate over radio, a that signal can get spotty, especially s thick walls. There are versions s wired connections between base a display, but that means running cables — not always convenient.
That’s why, v some cases, we installed them together s a water-based termostat, v a sequential setup. water termostat is set do 70 °C do prevent overheating, while Wi-Fi air unit manages comfort — say, do keep room pri 22 °C. result is a safer a more precise Riadiaci systém.
Wi-Fi termostat – water teplota
💧 Measures a regulates teplota vykurovanie fluid inside your system. These thermostats allow pre more precise kotol ovládanie, since they directly reflect a manage actual teplota vykurovanie medium — not just surrounding air.
🧰 Example: Konlen Wi-Fi controllers give you full ovládanie over system behavior, especially useful when tuning pre managing kotol performance more accurately.
💬 About Konlen thermostats (orange KL-WF-96D a blue KL-T-2T):
When Konlen KL-WF-96D ( orange one) first appeared, I literally jumped out my chair. Finally! I bought it right away na AliExpress, made a video guide, a posted it na site. People really appreciated it — clear, convenient, Wi-Fi-controlled, a working based na vykurovanie fluid teplota.
But as usual s Chinese manufacturers — it was almost perfect. biggest drawback KL-WF-96D was its size. It technically mounts na a DIN rail, but it didn't fit into standard plastic enclosures — too tall a not deep enough. I had do trim plastic, adjust mounts, add bolts — anyone who’s dealt s it will understand. na Konlen termostat page, there’s still a section pri bottom s all tricky installation details pre orange KL-WF-96D. That info will come v handy if you decide do go s that model.
Then v January 2024, KL-T-2T — blue Konlen — came out, a honestly, I fell v love. mounting is perfect: two DIN modules, fits like a glove. app interface got better, old schedule bugs disappeared, a everything just works as it should.
a precision — 0.1 °C. By comparison, older KL-WF-96D had 0.5 °C. Maybe that level accuracy is overkill pre water, but it actually made me think: why not try using it pre air teplota as well? I mentioned this v video I made pre it. I haven’t tested it that way yet, but honestly — s that kind accuracy, it could work really well v that role too.
💡 a what makes any Wi-Fi termostat truly powerful — air alebo water-based — is its ability do integrate into a smart ecosystem. Platforms like Tuya alebo Smart Life let you connect a ovládanie multiple devices from one app. If you already use one these platforms, you can easily add a Konlen Wi-Fi termostat do your existing setup — no need do create a new ecosystem.
You can start s something simple — like our kotol paired s a Konlen Wi-Fi termostat — a later expand your system s:
-
smart floor vykurovanie controls,
-
solar panel management,
-
alebo other Wi-Fi-enabled smart devices.
This creates a unified smart home experience, where vykurovanie, energy, a comfort all work together automatically.
