HISTORY

THE ONLY ALWAYS READY STOVE FOR LARGE AND MEDIUM-SIZED SAUNAS


Saunasampo Magic Stove is the world's first always ready electric stove. It was presented at the Tampere, Finland, Invention Fair in 1990. At that time, electric heaters were grills with the most common 20 kg, maximum 40 kg stove stones. Some big heaters in public saunas contained 60 kg of stones.

 

The 200 kg of stones in the Magic Stove revolutionized the electric heater market: it was possible to make an electric heater that was not a grill but allowed for moist, gentle steams. After the introduction of the Magic Stove, Helo's and Harvia's alwaysready heaters with more than one hunred kg stove stones were launched. Due to the patent for the Magic Stove these always ready heaters did not have a fan, which limited their area of ​​use to small saunas. Since then, the continuously heated Iki stove and it´s imitators have plenty of stones.

 

The first Magic Stove were installed in 1994. Among the first heaters was the Vanajanlinna´s Magic Stove, which has been in use as such for 28 years. There are also Magic Stove in the Finnish Parliament, two of them were purchased first for the staff and two more later for the  Members of Parliament.

 

Physically and functionally, the Magic Stove has not changed significantly. Instead, the control electronics have progressed from relay control through programmable logic to digital.

The Saunasampo Magic Stove is the only always ready heater for medium and large sized saunas. The stove is an insulated, heat-retaining storage stove with a lid and a fan. When the lid closes, the fan circulates the air in the stone chamber, protecting the heating elements from overheating and spreading heat to all stones. When the lid is opens, the fan circulates the sauna air through the whole stone chambe, raising the sauna temperature to the desired temperature in an instantly.

 

In standby mode, the stove consumes 2-3 kWh of electricity and the temperature of the sauna is intentionally 40-50 degrees so that the walls are comfortable to lean on as soon as the cover is opened. Unlike other always ready heaters, the heater does not have 300 - 400 W standby power, but all resistors are on / off. When the heating power of the stove is 16 kW, ie 16,000 W, even the coldest stove is ready for bath in an hour.

 

MAGIC STOVE IS AN ENERGY SAVING HEATER 

  

The Magic Stove is by far the most cost-effective energy saving heater. The longer the sauna is used, the more the Magic Stove saves. The greatest savings are achieved in 24/7 on-site saunas such as fire- and police stations and other three-shift workplaces. 

  

The Magic Stove saves an average of 5 kW per hour compared to a standard continuously heated heater. According to this, the annual savings per sauna are 43,800 kW, counted with an energy price of twenty cents per kWh, the annual savings are 8,760 €, which means that the Magic stove pays for itself inside a year. 

  

In a large sauna, the savings are even bigger because the stones in an insulated heater stay hot with much less energy than the walls and ceiling of a large sauna. In terms of energy savings, it can also be presented that, compared to a standard continuously heated stove, one continuously switched-on Magic Stove saves as much electricity as eight detached homes consume. 

  

The energy savings per sauna are proportional to the annual number of operating hours, i.e., for example 3,000 operating hours, i.e., in a 60-hour sauna, the savings are 3,000 h * 5 k W = 15,000 kW, i.e., the electricity consumption of three detached houses. 

  

If the sauna is turned on several times a day, the savings are proportionally bigger, because the stones inside an insulated stove do not cool much at intervals, unlike the walls and ceiling of a continuously heated sauna. 

  

In addition to saving energy consumption, Magic Stoves save on the connection power of the property. The power need of a Magic Stove is on average two-thirds of the power of a standard continuously heated heater, which reduces the front fuses of the heater. The Magic Stove also saves sauna panels and structures. 

 

CENTRAL FIRE STATION IN TAMPERE, FINLAND, HAS SAVED ENERGY OVER 9 YEARS

 

In Tampere Central Fire Station there is a large sauna for more than ten people, which is in heavy use because also divers are training there. The Magic Stove was continually turned on for 9 years before the sauna panels were replaced. The average consumption of the stove during that time was 5 kW per hour with sauna bathing included. In this case, the savings have been closer to 10 kW / h, i.e. the total savings are the electricity consumption of almost fifteen detached house saunas.

WE REMOVED WASTE OF ELECTRICITY


Most of the heat in a traditional sauna is used to heat the structures and sauna furniture, as well as to maintain their heat. Saunasampo Magic Stove heats the sauna air only in a few minutes and the desired sauna experience is achieved. When the sauna is still empty, the Magic Stove closes the lid, and the energy consumption decreases to standby mode.

 

For example, on a golf course where the sauna is used every day from morning to evening, electricity savings of more than 20,000 kWh per year are generated, which means that Saunasampo Magic Stove saves its acquisition costs almost in a year.

SMARTER MAGIC STOVE

 

Already the smartest of stoves, the Magic Stove has made a final breakthrough from ordinary stoves, with no hope of reaching the same level even in the next 15 years.

 

The Magic Stove has gone online in more ways than just temperature settings and timings. Its intelligence now includes a sauna monitor that tracks the sauna's conditions, a stove control system that monitors the stove, and an online user interface. Together, these form the sauna's remote control unit.

 

The smarter control system measures, displays, and records the temperature of the sauna as well as the stones inside the stove. It also logs data about the stove's resistor, fan, and lid motors. You can even monitor your sauna's energy consumption, steam levels, and humidity on its circuit boards.

 

The Magic Stove can be scheduled just like any mobile device.

 

You can set the days of the week, the timer's validity period, the sauna temperature, stove temperature, and lid opening time. Additionally, you can set different temperatures for different times, allowing each person visiting a communal sauna to have their desired sauna experience.

 

By scheduling when the lid of the stove opens, hotels can ensure it's always ready for visitors who want a morning sauna. Treatment facilities won't need to worry about remembering sauna timetables either.

 

If no schedule is set, the lid can be opened from the control panel and set to close after a desired amount of time.

 

 

 

ONLINE USER INTERFACE

 

The attached pictures show the user interface of the new, smarter Magic Stove.

 

The thicker red line displays the stove's temperature (scale on the left), the orange area represents the sauna temperature, and the blue area represents the relative humidity of the sauna, indicating steam released from throwing water on the stones. The bottom bar shows red when the resistors are on, black when they are off, and yellow when the stove lid is open.

 

This particular sauna is heavily used by approximately 8 people. It has a 16.2 kW heater with 300 kg of Kerkes stove stones. The electricity consumption of the sauna in the picture, while in use, is about 6 kWh per hour. In standby mode, with the lid closed, the consumption is about 1.5 kWh per hour.

 

From the user interface, you can see that the stove maintains the preset sauna temperature even during intense use when the lid is open. The 24-hour display shows that at night, when there are no users, the resistors are turned off almost all of the time.

 

The stove can fit in almost any required space. In a relatively small sauna, you can set the stone temperature of the stove close to 200 degrees Celsius, and in a large sauna, close to 300 degrees Celsius.

 

Below is a screenshot of the temperature timetable of the stove, which is set every day until the end of November, along with the user interface for scheduling.

 

THE MAGIC STOVE IS A SAVING STOVE

 

Attached is an INVESTMENT CALCULATION showcasing its savings. It demonstrates that the stove saves about 50% on electricity costs. The actual savings in euros depend on the price of electricity and the amount of time the stove is in use. In a sauna that is constantly running, the stove pays for itself in less than a year.

 

The Magic Stove mentioned above is only hot during sauna sessions. In standby mode, with the lid closed, it maintains the sauna temperature at 40–50 degrees Celsius. You can immediately enjoy a humid bath in the sauna, and from there, it quickly heats up to the pre-set temperature in a few minutes. When the sauna is hot for only a short time, the panels and boards of the sauna do not dry out, significantly extending their lifespan.

 

Tampere Central Fire Station has a large sauna for more than 10 people, equipped with a 21 kW Magic Stove and 300 kg of Kerkes stones. The stove has been in heavy use, as it is utilized by the fire brigade and divers training at the station. After 9 years of operation, the sauna panels were replaced. The stove consumed 5 kWh per hour during sauna usage.

 

SMARTER MAGIC STOVE TECHNOLOGY

 

The stove doesn't have a traditional, separate control center like a regular floor-standing stove. The Gateway box, installed outside the sauna, handles the stove's internet connection. The logic center is located in a moisture-protected space inside the plinth of the stove, collecting all data about the sauna and the stove while controlling its functions.

 

The stove's software can be updated and reset via the internet, ensuring it always has the latest version.

 

The stove doesn't require a strong electric current for functions other than powering its heating elements. It operates with semiconductors, unlike modern stoves that use failure-prone mechanical contactors.

 

The fan motor is a 24 V DC brushless motor with a manufacturer-promised lifetime of 100,000 hours. Such a motor is used, for example, in electric lawnmowers, where the operating stress can't even be compared to circulating air inside a stove.

 

Compared to the current GL series stoves, the installation and maintenance of the smarter EL series stove are significantly easier and simpler. The stove's power supply requires a 5 x 6mm2 rubber cable. It can be installed as a replacement for any existing continuous heating stove.

 

In addition to the input cable, a data connection is needed from the stove outside the sauna to the Gateway box. A temperature sensor, lid control button, and/or motion sensor can also be linked together, placed on the sauna wall.

 

The electronics inside the stove's plinth are placed on a device platform that can be easily pulled out during repairs. In the event of a major fault, the device base can be replaced without requiring special professional skills, ensuring minimal interruptions.

 

In practice, the only parts of the stove that might wear out are the Kerkes stones and heating elements. The replacement interval for both depends on the usage. In communal saunas within apartment buildings, the replacement interval is several years, while in home use, it can be tens of years.

 

The stove is assembled from replaceable parts, ensuring its longevity practically lasts forever.
