The Willer trademark belongs to the Serbian water heater manufacturer Metalac Bojler. Metalac Boiler is a fairly young company - it started its work in 2006 and is engaged in the production of only water heaters for the European market. Metalac Boiler is the owner of the ISO 9001:2008 Integrated Quality Management System and ISO 14001:2004 Environmental Management System certificate. The main slogan of Metalac Boiler, the official manufacturer of Willer water heaters, is honesty to its customers.
WILLER PREMIUM water heaters are manufactured at the Metalac Group plant in Serbia.
Metalac was founded in 1959. The main office is located in Gornji Milanovac. The corporation includes 13 companies, of which four are production companies. The enterprise for the production of water heaters was founded in 2006.
In the production of water heaters, original developments and a wealth of experience accumulated over more than five decades of active work in the field of enamel surface technology and more than three decades in the production of key components for water heaters are used. Willer's manufacturing program is ISO 9001:2008 Quality Management System and ISO 14001:2004 Environmental Management System certified.
Metalac Boiler is the youngest company within the Metalac Group from Gornji Milanovets. It was founded in 2006 and is engaged in the production of water heaters for commercial and direct consumers.
Over 50 years of experience in enamel technology for surface protection and more than 30 years of experience in the production of the main components of water heaters were decisive in the fact that Metallac chose the production of water heaters under its own brand "Metallac Boiler". And so begins the independent performance of this enterprise in the trading market. In 2008, the construction of new production halls with an area of 4.500 m2 begins, which were put into operation in 2009. The production capacity of the new factory is 230 thousand units per year.
The production program includes: Medium volume water heaters from 30 to 120 liters with enameled and INOX tanks, large volume water heaters from 200, 300 and 500 liters, small volume water heaters from 5, 8 and 10 liters, with enameled, INOX and polypropylene tanks.
