History

Even the Alps started off small. Like the mountain range at the heart of Europe, Hoval has grown into a firmly established entity.

1932

Gustav Ospelt obtains the authorisation to build heating systems.

1942

The cornerstone is laid: a simple stove gives rise to a central heating system. Gustav Ospelt patents his idea and the EMPA confirms its high efficiency in a test report for the first time.

1945

The "Hoval" brand is registered. The name stands for heating equipment construction Ospelt Vaduz Liechtenstein.

1946

First internationalisation with the establishment of companies in Austria and Switzerland.

1953

The first boiler with an integrated hot water tank, the Hovaltherm, nicknamed "the rocket", revolutionises the European boiler market.

1955

A licence agreement with the Friedrich Krupp steel company for steel boilers generates rapid growth and opens up the German market for Hoval.

1957

Construction of the "Neugut" site in the Vaduz industrial zone. Since then, this has been the headquarters of the Hoval group of companies.

1957-1967

During this decade, companies are founded in Great Britain and Italy, and additional favourable licence agreements are signed.

1960

The first compact combination boiler with separate combustion chambers for liquid, gaseous and solid fuels is ready for the market – in eight different versions.

1967

The first high-performance calorifier, Modul-plus, still guarantees the highest levels of hot water comfort today, performing superbly under fluctuating peak requirements while meeting the most stringent water hygiene specifications.

1967

Hoval celebrates a milestone: the 100,000th boiler leaves the Vaduz works. In all of Europe, 350,000 Hoval boilers have already been built by this time.

1967

Hoval receives its first heating surfaces patent for the "Fischgratrohr" design, which achieves enormous gains in heat transfer and therefore in efficiency. Further heating surface patents follow in 1972 and 1979.

1970

Expansion of the product spectrum to include industrial ventilation units and aluminium plate heat exchangers for heat recovery in climate control and ventilation systems and in processing technology.

1976

Introduction of a decentralised unit for ventilating industrial halls with heat recovery. Use of these units reduces heating energy needs by up to 60 percent.

1979

Registration of a trend-setting patent: the self-cleaning thermolytic heating surface. An entire series of small and medium-sized boilers is named after this Hoval achievement: their names end in "Lyt".

1982

Hoval develops a unique vortex air distributor, the Air-Injector, for even greater efficiency in the ventilation and heating of industrial halls.

1984

Hoval starts a development project with Ruhrgas Deutschland for gas premix burners. These burners guarantee particularly low levels of emissions during combustion. The new development enters into series production in 1986 under the name of Ultraclean®.

1987

With the wood gasification boiler, Hoval focuses on gasification technology for biomass for the first time. The three-stage combustion method soon becomes the market standard.

1993

Research on the most efficient gas condensation design, which was started in 1984, culminates in the patented Hoval aluFer®, a heat exchanger with an integrated aluminium microstructure. Energy efficiency, cost savings and a long service life are just some of the advantages of a whole generation of condensing gas units, which first went into series production in 1994.

1994

The patented technology of the first Hoval recirculation cooling unit makes cost-effective heating and cooling of high halls possible with only one unit.

1999

Hoval launches the MultiJet® oil condensing boiler with a revolutionary heating surface. Its jet technology achieves optimal heat transfer levels, resulting in excellent efficiency, very quiet running and an exceptionally compact design.

2001

The use of alternative energies enters a new dimension with the development of the horizontal tube burner for pellet burners. Efficient, compact, reliable and comfortable – these words describe the conversion of wood to heat by the BioLyt series (2005).

2001-2004

Hoval expands its worldwide sales network to include its own branch offices in Poland, the Czech Republic and Slovakia.

2004

Hoval develops a special sorption coating for thermal wheels, which transfers not only heat but also humidity. This technology creates a constant, pleasant indoor climate and superb comfort in the home by means of ventilation systems featuring cooling or humidity control, such as the HomeVent® controlled residential ventilation system.

2005

After over 20 years of business in China, Hoval founds its first sales company in Asia.

2006

UltraOil®, the first oil condensing unit based on the aluFer® heat exchanger, goes into series production. Today, this is a highly successful range that generates power outputs of 16 – 200 kilowatts.

2006-2008

The latest Hoval sales companies open their doors in Romania, Spain, France and Croatia.

2007

Environmentally friendly cooling with refrigerant-free recirculation, not only reducing water consumption but achieving maximum adiabatic efficiency levels.

2008

Hoval invests in the production of heat pumps with Wärmepumpen GmbH in Matrei (WPM), East Tyrol, Austria.

2010

Hoval introduces the new business sectors of heat transfer stations and combined heat and power plants.
