Questions & Answers:

Is it Safe to Put Water on Electric Sauna?

Yes. If you’re worried about getting electrocuted by adding water to your sauna heater, take note of these few things:

  • Electric sauna heaters cannot handle water being poured on them. That said, your electric heater can handle a drizzling of water on them. This will boost your sauna experience by adding steam to your sauna and raising the humidity of your home sauna.
  • Pouring water on any electric device will cause it to short-circuit and poses a fire hazard.
  • A few splashes of water on your electric stove is enough. This also prevents your room and heater from getting overwhelmed.

How Do You Size a Heater?

The general formula is 50 cubic feet = 1 Kilowatt. Say for 300 cubic feet sauna rooms; you’ll need sauna heaters that are 6 Kilowatt.

Size a Sauna Heater

 

However, you need to consider that outdoor saunas built for outdoors will need an oversized heater.

What is the Difference Between An Electric and An Infrared Sauna Heater?

The biggest difference noticeable to those who have tried both kinds of saunas is the heat. If you’re sensitive to environmental heat, you may not enjoy your time in a traditional sauna.

That’s because traditional saunas usually maintain a high temperature of up to 195 degrees Fahrenheit.

Adversely, if you install an infrared sauna heater, you don’t need to raise the room temperature to notice its effects.

Things to Remember Before Shopping For Sauna Heaters

There are many factors you need to think of before purchasing heating elements for your sauna.

For starters, what kind of sauna do you want?

There are a variety of sauna types:

  • Wood burning sauna
  • Dry sauna
  • Finnish traditional saunas
  • Gas Sauna
  • Infrared saunas

Size a Sauna Heater Design

Once you’ve determined which sauna type you’re looking for, you can start deciding which model is the best for you.

  • If you’re choosing an electric sauna heater, make sure it’s easy to use and made of stainless steel to achieve the best electric sauna.
  • For wet dry saunas, an electric stove that heats sauna stones is ideal.
  • A gas sauna is understandably more so meant for dry heating.

Sauna Heaters: Final Thoughts

The Finlandia Harvia FLB-80/KIP-80B is my top choice. Why?

  • It’s practical – it’s a no-fuss purchase. There are no extra attachments included, and there’s nothing more you need to do except installing it, fill it up with stones and start using it.
  • Durable – it’s made of stainless steel both inside and out, so you know it won’t rust or corrode. This means you’re investing in something that’ll last you a long time.
  • Quick-heating – it heats up quickly because of its stainless steel construction. It’s also wall-mounted, so it dissipates heat evenly and more effectively. Additionally, it also frees up floor space, so if you’re trying to keep as much floor room as possible, it’s perfect.

There are more reasons that led me to choose FLB-80.

However, I understand some of you might be looking for something with a bit more “flair.” In that case, the Tylo Sense Sport is the perfect heater for you.

This premium luxury model comes with a host of great features you won’t find on the Harvia.

But it’s also very expensive. So if you’re fine with spending nearly $500 on a sauna heater, you’ll love the following features:

  • Aromatherapy – you’ll enjoy the bonus ambiance by putting herbs or essential oils on the designated aromatherapy well. It’s also there to keep water for humidity so you can ladle water on it more easily.
  • Fastest Heating – this luxury heater boasts the quickest heating time in the market. You’ll enjoy lounging in your sauna in no time because of this. Additionally, it also effectively spreads heat throughout your sauna more evenly.
  • Thermosafe Casing – its unique thermosafe shell makes sure you don’t get accidentally burned while trying to access your sauna heater. At its hottest, the most you’ll feel is a steady warmth.

But if you’re looking for something that’s more budget-friendly without skimping on the features, the Vevor Sauna Heater is the best option.

This handy and compact sauna heater is packed with great features. It’s also relatively inexpensive, so it’s a great first sauna heater for your home or business.

  • It’s versatile. That means you can use it as a wet or dry sauna heater.
  • It’s durable. Thanks to its premium stainless steel construction, this sauna heater won’t corrode or rust in time. It’ll simply heat up your space reliably and quickly.
  • It has safeties against overheating. This feature is great to have, especially if you tend to forget to monitor your heating unit. Once it goes over a certain temperature, the unit will automatically shut off and cool down on its own.

So you see, whichever unit you choose, you’re bound to fall in love with it.

There are plenty of options listed above, and I’m sure you’ll find one that fits your needs specifically. And if you don’t? Well, at least you now know what to look for in your sauna heater.

Make sure you remember to:

  • Consider your space. The formula is: 50 cubic feet = 1 Kilowatt
