Established in 1874, German company Vaillant has
gone on to make ground-breaking contributions to home heating and today has a wide range of gas boilers, renewable energy
products and even air conditioning.
Vaillant was founded in 1874 when a 23 year old tailor’s son declared in the
newspaper in Remscheid that he had “established himself as a coppersmith and pump manufacturer”.
By 1894 Vaillant had patented the “closed system” boiler that allowed
water to be heated without being contaminated by combustion gasses for the first time.
In 1905 Vaillant developed a wall-hung boiler that could fit into any room and in
1924 a revolutionary central heating boiler. Previously, each room needed a fireplace to heat it, but for the first time all
the rooms in a house could be warmed from a central location.
The “Combi-Geyser VCW 20“ combines - for the first time - heating and hot water supply in a single
unit, launched in 1967.
By 1997 Vaillant had completed
a range of solar-thermal systems for heating drinking water - the start of its renewable energy products.
In 1999, after 125 years, Vaillant had supplied 40 million units and over the past
10 years has invested in and developed a range of even more efficient heating systems and renewable energy products.
