HEIZER was founded as an individual company around the mid-60s, as a small company which built gas storage water heaters in the heart of Milan.
This company adopted the name “A.P. Scaldabagni”, the first forerunner to the present company, HEIZER GAS. Despite the financial difficulties of that period (unfavourable interest rates and high inflation), “A.P. Scaldabagni” managed to carve out a small place for itself within the national landscape of gas storage and electric storage water heaters. After a few years this would lead to a first move to places not so distant but decidedly bigger.

It was in 1972, however, that the actual change to a reality that still exists today occurred: the move to Bollate, a small industrial centre near Milan.
Finally, thanks to even bigger spaces for production, marketing and sales under the new name HEIZER GAS were able to begin. The changeover from an artisan business to a commercial business had begun!

There is another important date in the history of HEIZER: 1995; that is when the move to the present headquarters in Garbagnate Milanese took place.    

In the meantime, through intuition the Company was able to see the growth potential of floor-standing commercial water heaters, focusing most of its efforts and investing on such a niche product like the commercial water heater.

The last few years have seen HEIZER expand its range even more, adding a new calorifiers and buffer tanks catalogue. In addition, HEIZER has reached an agreement with a well known Japanese company for the exclusive distribution of a dynamic line of instant, Hi-tech, professional-use gas water heaters to many European and extra-European countries.
