On returning home after WWII, Philipp Kreis opens a language school in Munich. The lack of mains power in the post-war period poses a major problem for evening courses, giving him the idea of going into gas light production.
Due to the increasing demand for gas lights, Philipp finds himself producing and selling them in large quantities in a very short space of time. On 27 October 1949, he registered his trade under the company name Truma.
The brand name Truma stands for the name of the then US president Harry S. Truman, who the company’s founder Philipp Kreis very much admired due to the instrumental role he played in restoring Germany to an industrial nation.
The Truma gas light solves lighting problems when no electricity is available. On 10 November 1950, a patent is granted for the invention of a gas light for all flammable gases. It is the first patent for Philipp Kreis.
The language teachers no longer teach, instead they work as development and assembly personnel for Truma.
The Truma heat radiator is available. A heater that runs on town and bottled gas and delivers 440 thermal units (= 0.5 kW).
It is the ideal small heater for many applications – and, thanks to the exhaust gas system, is also suitable for household purposes and vehicles.
The Model 55 light is mass-produced. It is the first light on the world market to be fitted with a heat-resistant diaphragm valve. A new pear-shaped opal globe with reflector increases light output by 25%.
Truma now has twelve employees.
The Truma valve with diaphragm seal, patented since 1955, is improved to the “quick-acting valve with rotary switch” and is produced in many models with different connections.
The valve can be used universally for compressed air, gas and many liquids. The diamond-shaped operating handle clearly shows the position of the valve.
The Truma high power light has adjustable luminosity to 600 Kz (= 400 watts) and can be used as a table, hanging, standing and work light directly on the cylinder. The multi-purpose light is ideal for trade and industry and works without a power source.
Old flame – new logo: The Truma logo is developed from a circle and a flame and remains to the present day.
“Truma-Post” is a newsletter with an informal layout that contains amusing drawings and sayings. It is intended for customers and employees and is the predecessor of today’s employee magazine “Wir Trumaner”.
The new freedom and larger caravans demand more heating power: therefore, Truma introduces the Trumatic-S 3000 with 3000 HU (= 3.5 kW) to the market.
The visual appearance of the heater is improved the following year: the new smooth cover can be removed easily, while slits allow users to see the flame. With the Trumatic-SD 2000, SB 1800 and S 3000, Truma offers “the right heater for every caravan”.
After completing her business studies degree, Renate Schimmer, the daughter of the company founder, joins the family business.
In 1970, Philipp Kreis is awarded the Order of Merit of the Federal Republic of Germany for his pioneering work in the development of propane gas systems and central oil supplies. The award is presented by the Mayor of Munich at that time, Dr. Hans Steinkohl.
18 Truma service technicians now travel throughout Germany with their service vehicles. Thanks to shorter travel times, they arrive where they are needed very quickly and can visit the camp sites more often.
Thanks to its safe, maintenance-free functions, the Trumatic E is increasingly popular in lorry cabins, stowage areas and on boats.
For the second generation of the electric heaters the burner and heat exchanger are redesigned and the heater is given a plastic housing. This means that the heater can now also be installed outside the vehicle.
Truma designs a mini heat exchanger that provides the desired heat output due to the shape of its surface.
It is used in the new Trumatic-E 1800 heater, which can be installed in many different locations because of its small size; in compact motor homes, small lorry cabins, sports boats and as an additional heater in large caravans and motor homes.
In the successor of the tried and tested Trumatic-E 1800, heat output is increased to 2.4 kW without any increase in size.
The heater also works reliably at minus 30 degrees Celsius, is incredibly quiet, consumes little electricity and requires no maintenance. With all its benefits, it immediately becomes the most popular Trumatic-E heater.
The commercial register entry “Philipp Kreis GmbH & Co, Truma-Gerätebau” is changed to “Truma Gerätetechnik GmbH & Co”.
This new name is intended to express that fact that Truma invests in new products and markets outside its traditional areas.
Truma launches the Truma Combi, its new heating system for motor homes. Replacing the Trumatic C, of which more than 500,000 units were built, the Combi is more compact and even more lightweight. It also features Frost Control, the first entirely current-free drain valve.
Even before it had its market launch, the new Truma Combi heating system won the reddot design award for 2007. Alongside the Truma Mover® manoeuvring system, the new Truma Combi heater is the second Truma product to enjoy the accolade of the reddot quality seal.
The opening of the company’s Italian subsidiary Truma Italia S.r.l. brings Truma even closer to its customers in the rest of mainland Europe.
Truma joins forces with CALIRA, the leading supplier of power supply equipment and control and display panels for recreational vehicles.
Renate Schimmer-Wottrich is resigning from the management board to take over as chair of the advisory board.
The new Truma Combi D motor home heater sees the addition of a diesel product to the Combi family. The Combi D is the lightest and yet most efficient diesel combination heater on the market.
Truma continues to grow, opening an agency in China so that it has a local base right from the start as the caravanning market takes off in the region.
The new Mover® R manoeuvring systems are introduced, offering yet more power and reliability.

Truma is now advancing into the roof and air conditioning market as it launches the new Aventa Comfort for caravans and motor homes. The Aventa air conditioning system supports not only cooling but also heating, with its energy-saving heat pump. Thanks to its cooling power of 2400 Watts and the extremely flat air distributor in the interior, the Aventa sets new standards among roof air conditioning systems.
The Mover® TE R4 is being introduced. This means that two-axle caravans and trailers up to a total weight of 3000 kg can now also be manoeuvred.
The proven Mover® SR has been completely overhauled. Thanks to its higher output, it can now move caravans weighing up to 2,000 kg. It stands out thanks to its optimised design that now protects the motor and transmission even more effectively against corrosion, oil, salt and wet.
In 2012 Truma celebrated a special anniversary: 50 years of caravan heaters.
The rooftop air conditioning unit Aventa eco is launched. It stands out thanks to a high cooling output of 1,700 Watt and low power consumption. The product also won the Reddot Design Award and the Caravaning Design Award for its appealing modern design in 2012.
The Truma gas filter protects regulators and valves effectively against soiling and oil. A further innovative addition to the gas supply range is the Truma LevelCheck. This device shows the filling level of gas cylinders and uses an ultrasound process to detect whether there is liquid gas in the cylinder at the measuring point. It also won the Caravaning Design Award.
Truma offers two new versions of the legendary S-heater: The S 3004 and S 5004. They not only retain the proven quality features of the predecessor models, but also set new standards in terms of operating convenience, warm air distribution and design.
Truma launches its fuel cell system VeGA. It guarantees a self-sufficient power supply completely independent of the mains supply. The VeGA uses liquid gas to generate energy in an environmentally-compatible and efficient manner, thereby charging the supply batteries. By virtue of its high output power of max. 250 Watt (6,000 Wh a day), the VeGA reliably secures the individual energy requirements.
In 2013 Truma won the innovation prize "Top 100" as one of the most innovative medium-sized companies in Germany.
The Truma SolarSets are launched. They are available in four performance models and guarantee excellent energy efficiency per surface thanks to their mono-crystalline structure.
The new Saphir comfort RC can either cool and dehumidify with 2,400 W or heat with 1,700 W. Despite the new integrated heat pump, it is the smallest under-bench air conditioner of its class.
Truma launches a new digital control panel for its Combi heaters: the CP plus offers much more operating comfort and lots of new functions.
Truma's Mover® XT sets new standards for manoeuvring systems. Thanks to its brushless motors, the XT guarantees unprecedented manoeuvring precision and also saves up to 20 kg in weight. The new Mover® PowerSets with the new lighter Truma BC 10 charger are perfectly matched to the Mover® XT.
Truma continues its internationalisation strategy and founds subsidiaries in the USA and China.
Truma launches a product specially developed for the North American market, the Truma AquaGo®. The continuous heater produces an infinite supply of warm water at a constant temperature at the push of a button.

In 2014 Truma celebrated its 65th company anniversary.
2015 Alexander Wottrich joined Truma to continue its successful history as a family company in the third generation. As managing director, he is responsible for all corporate activities of the Truma Group. This not only includes Truma Gerätetechnik, but also the two companies Alde, which is based in Sweden, and Powrwheel based in Great Britain. Renate Schimmer-Wottrich supports her son in her capacity as deputy managing director and also remains a member of the supervisory board.
A new era begins: Truma launches the iNet System. It digitally networks Truma devices, such as the Combi heater and air conditioning systems, allowing these to be controlled per smartphone when on the go.
Truma is awarded the innovation prize TOP 100 for the second time.
The Truma iNet System wins the European Innovation Award. The jury, which comprises trade journalists from 16 European caravanning magazines, names the Truma iNet System the most innovative accessory product for retrofitting.
Renate Schimmer-Wottrich is awarded the German Camping Prize at the Travel & Camping exhibition in Essen. This award acknowledges the Truma owner’s dedication to caravanning and camping. She has campaigned on behalf of the campers to make mobile recreation more comfortable and safe for decades.
