Sauna oven: what kW power is required?

The size of the sauna is crucial for the selection of the optimal sauna heater. From our many years of experience, we recommend heaters with the following output:

• Sauna size between 3 and 6 m³ = > sauna heater with 4.5 kW capacity
• Sauna size between 5 and 9 m³ = > sauna heater with 6.0 kW capacity
• Sauna size between 8 and 11 m³ = > sauna heater with 8.0 kW capacity
• Sauna size between 10 and 12 m³ = > sauna heater with 9.0 kW capacity

If the glass content of the sauna is high, however, a sauna heater with higher performance may have to be chosen. When planning a sauna, we advise you on the right selection. In general, a distinction is made in the sauna heaters between an oven suspended on the sauna wall (wall-hanging oven), a free-standing oven (e.g. in front of a glass front) or a rear wall furnace (hidden oven behind the sauna wall). We match the selection of the right oven to the sauna design.

Which power connection is required for the sauna oven?

For a high-performance sauna oven, high current with 400 V is basically required. Here you will find detailed information: Sauna planning: electricity connection and cables >

Tip: free-standing sauna heater

If your sauna has a glazed corner, a free-standing sauna heater is particularly fine. In order to ensure that no visible connection cables disturb the perfect optics at the end, we recommend – if feasible – to lead an empty pipe under the screed to the planned heater position in good time during construction. Please contact us early if you are planning your house construction or conversion, so that the power connections and cables can already be laid appropriately.

Bio sauna: What is a combi sauna heater?

It is not only the kW performance of the oven that matters – it is also crucial how you want to use your sauna: a normal sauna heater is sufficient for the Finnish sauna (approx. 90 °C/10 % humidity). If you also want to use your sauna as a bio sauna (approx. 60 °C/40 % humidity), the sauna heater must be equipped with an evaporator. This is then a so-called combi heater or combined sauna oven. With the water vapor from the evaporator, the humidity in the sauna is increased. With a combi heater you are completely flexible: the evaporator can be switched on or off, i.e. you can sauna with it in the Finnish way, but also use the sauna cabin as an bio sauna on another day.

In the case of a bio sauna, it should be noted that exhaust air is necessary to actively guide the moisture from the sauna to the outside after sauna use (to avoid mould formation). All information about the sauna forms can be found here >

Replacing the sauna heater

You already have a sauna and would like to retrofit your sauna heater…? On request, corso also provides you with a new sauna heater or a new sauna control system if your previous model is defective or if you want to upgrade to a newer model (whether your existing sauna was built by corso or not or if you want to build your own sauna DIY). In view of the large selection, we recommend you to talk to us in advance, so that we can offer you the most suitable technology for your sauna. We are looking forward to the conversation! CONTACT >

Changing sauna stones

The sauna stones should be renewed after 3 to 6 years, but at the latest if they become brittle or start to smell. Otherwise, small splinters could damage the heating rods of your oven. Order new sauna stones: SHOP >

When, how much and what should I drink when taking a sauna?

After sauna, you should drink at least one litre of water or Spritzer. Or you can weigh yourself before and after to determine the exact loss of fluid during the sauna sessions. This loss of fluid should then be (at least) completely compensated. If you don’t drink enough, even headaches can result – and you certainly want to avoid that!

Experts do not entirely agree on the right time to drink. Some recommend for the best detoxification effect, to drink only after the end of the complete sauna and not already between the sauna sessions. However, your well-being is crucial: if you are thirsty beforehand, it is always better to drink something and listen to the signals of your body. If you do not have a thirst between the sessions, you should drink plenty before and after the sauna visit, which will in any case promote detoxification.

What should you eat before sauna?

Before and after sauna bathing, you should only eat light food: because during the sauna, your heart already has to pump significantly more blood, the circulation and metabolism come on full speed. If you do this with a full stomach, your body will have to compensate for a double load – and this is not particularly conducive to the relaxation effect. Therefore, fresh fruit or a salad are recommended to provide the body with vitamins.

How does detoxification work when sauna bathing?

By sweating in the sauna, the body loses liquid. As a result, the blood is thickened as water is removed from the blood. The thicker blood then absorbs more pollutants, which are then filtered through the kidneys and excreted with the urine. The toxins are thus not primarily sweated out by sweat, but filtered and “discarded” via the internal organs.

At what age are children or infants allowed to go to the sauna?

There are no clearly defined ages for when an infant or toddler is allowed to go to the sauna. According to the recommendations of the German Sauna Federation, it is already “possible from the 4th month” if the baby is completely healthy according to U4. The professional association of paediatricians and adolescent doctors BVKJ, on the other hand, advises against using a sauna before the first year of life. Ultimately, it is up to parents to decide whether to take their child to the sauna before their first birthday. But from then on, nothing should stand in the way of the common sauna pleasure if the child is healthy and enjoys it (which is usually the case with infants in our personal experience!).

Sauna with children: what do I have to consider?

It is important that you proceed slowly and carefully and pay attention to your child’s reactions: it is best to start with comparatively low temperatures of around 60 degrees in the Finnish sauna without infusions. Start with a short session of 3 to 5 minutes on a middle or lower bench. For the first time, you should limit the common sauna bathing by one session. To cool off, the child should take a lukewarm shower, go to the fresh air, drink enough – and then cuddle and relax together with the parents.

Depending on how your child likes it, you can increase to two sauna sessions after a while. It is important that the child is always together with you as a parent and that it is not unaccompanied in the sauna! Of course, it is best to sweat together with the offspring in your own sauna at home. If you want to take your child to a public sauna, inform yourself in advance whether and at what age it is possible or if there are special times for the “infants or children’s sauna” if necessary.
