Why you shouldn’t drop water on a sauna heater: checklist
For many people, visiting a sauna is a real pleasure. Especially when there is a blizzard outside. This tradition originated in Finland, where people were forced to find effective ways to keep warm. The hissing sound of water hitting hot stones is considered the “soul of the sauna.” People in its home country call it «löyly» and do it all the time as a way to relax. However, there is a fine line between relaxation and unintentional damage to equipment. It can even pose a threat to the safety of guests. In fact, Harvia brand heaters are well known for their durability and reliability. Meanwhile, many are curious about what happens if you pour water on a Harvia sauna heater. Honestly, the answer is ambiguous. So, let’s figure it out.
Water and Steam: Is It Safe to Drop Water on a heater?
To understand all the risks, you need to delve deeper into the subject. In general, a heater is a device consisting of heating elements and a combustion chamber. These stones act as a heat exchanger. Well-heated cassettes can instantly evaporate liquid. The key reason why it is not recommended to pour water or spray it is thermal shock. The water won’t turn into steam right away if the stones aren’t hot enough (about 70°C).
Instead, it will seep through the cracks in the stones and fall directly onto the red-hot heating elements. These parts are made of heat-resistant metal alloys. However, even they have their limitations. Rapid cooling caused by a sudden flow of water can cause the metal to contract quickly. In this case, it contributes to the formation of microscopic cracks, dents, or short circuits.
What’ll happen if you pour too much water?
Many people think that the more water vapor there is, the hotter it will be. This is the main mistake beginners make. In fact, the opposite is often true. So, what happens if you pour too much water on a Harvia heater? There are several consequences. Your actions will effectively “flood” the stones and lower the temperature in the room. This creates a heavy and humid atmosphere that will cause suffocation. No one will feel comfortable there. Actually, excess water that does not evaporate will accumulate at the bottom of the heater. Of course, the devices are designed with drainage and airflow in mind. However, this does not mean that you can pour water uncontrollably.
This moisture can cause corrosion of the inner casing and potentially damage the internal wiring. Thermostat sensors are the most sensitive. Furthermore, if you’ve ever wondered, is it safe to pour water on a Harvia sauna heater? If the stones are too tightly packed, then no. This is because such a composition prevents air access and proper circulation. As a result, don’t be shocked if you need to quickly purchase another one. By the way, in such cases, no warranty is provided.
How to do «Löyly» step-by-step?
Firstly, you must follow safety rules. You could always get a ladle. But making sure everything is done right is another matter. That’s why we’ve prepared a few tips on how to organize this. So, let’s get started!
- Check the burning temperature. In fact, you cannot pour water if the temperature has not reached 65°C. Sure, the stones should hiss immediately. Only then should you stop pouring;
- Limit the ladle. Use a standard sauna ladle. This is usually about 200 ml. One full bucket will be enough for a comfortable stay;
- Wait for the stones to cool down. Give the stones 5-10 minutes to rest before the next pouring. They need time to absorb the heat after cooling down;
- Direct the water onto the stones. Note that water should not come into contact with metal. Make sure the stones are stacked correctly so that the heating elements are completely covered. Otherwise, corrosion or breakage is not far off;
- Water quality. Use only clear, uncontaminated water. Refrain from adding chlorinated water from the pool or essential oils. Even a small amount of contamination will quickly lead to negative consequences;
- Stone care. Once a year at the very least, check the stones. If they are cracked or crumbling, they will not evaporate water effectively and should be replaced.
