Ever wondered what that snowflake symbol on your radiator is trying to tell you? It’s confusing when your heating system seems to have a secret code, and ignoring it could leave you freezing or overpaying on energy bills. Don’t worry—understanding these symbols is easier than you think, and this guide will break it all down to keep your home cozy and efficient.

The snowflake symbol on a radiator typically means the frost protection setting on a thermostatic radiator valve. It ensures your radiator stays just warm enough to prevent pipes from freezing when temperatures drop, usually around 5-7°C, saving energy while protecting your system.

But there’s more to radiators than just the snowflake. Stick around as we unpack other symbols like the moon and star, so you can master your heating system like a pro.

What Is the Snowflake Symbol on My Heater?

Let’s dive into that snowflake symbol you’ve spotted on your radiator. It’s not just a cute design—it’s a key feature of a thermostatic radiator valve (TRV), like those made by Danfoss or Honeywell. The snowflake indicates the frost protection mode, which kicks in when the room gets too cold, usually below 7°C. This setting keeps the radiator at a low heat to stop pipes from freezing, which can cause cracks or leaks—nobody wants that headache!

If you’re in a chilly place like Poland or Russia, where winters bite, this feature is a lifesaver. It’s automatic, so you don’t need to fiddle with it. Just set it and forget it. Curious about thermostatic radiator valve installation? It’s straightforward—most TRVs, including ours at IVALVECRAFT, come with clear manuals, and pros can fit them fast. The thermostatic radiator valve installation cost varies, but it’s a small price for peace of mind. Whether you’re a wholesaler or a construction buyer, stocking TRVs with frost protection is a smart move for your customers.

What Is the Moon Symbol on a Radiator?

Now, let’s talk about the moon symbol—it’s another one that pops up on radiators and can leave you scratching your head. The moon usually means the night setback mode on a thermostatic radiator valve. This setting lowers the radiator’s temperature during the night or when you’re not home, saving energy without letting the room get too cold. It’s perfect for keeping things cozy while cutting down on bills.

Say you’re running a DIY chain in Germany or the UK—your customers will love TRVs with this feature because it’s practical and eco-friendly. Wondering how does a thermostatic radiator valve work? It senses the room’s temperature and adjusts the heat automatically. No guesswork! For one-pipe steam thermostatic radiator valves, the moon mode is a game-changer in older buildings, keeping heat steady without wasting energy. At IVALVECRAFT, our valves are built for stable performance, so your clients get reliability with every turn of the dial.

What Does the Star on the Radiator Mean?

Okay, what about that star symbol? It’s not there to make your radiator look fancy—it’s another setting on your thermostatic radiator valve. The star often stands for the maximum comfort setting, cranking up the heat to keep your space toasty, usually around 20-22°C or higher. Think of it as the “I want it warm now” option for those extra-cold days in Romania or the Czech Republic.

If you’re a purchasing officer for a big construction project, you’ll want valves that offer this flexibility. Customers ask, “Thermostatic radiator valve—how to use it?” It’s simple: twist the dial to the star when you need quick warmth. Our IVALVECRAFT valves, whether for thermostatic radiator valve steam systems or standard setups, deliver consistent flow and durability. Plus, they’re easy to explain to end-users, which is a win for wholesalers and retailers alike. Stocking valves with clear symbols like the star makes your product range stand out.
