From its very beginning, heater production in Poland has fallen under the purview of the European Quality Control System. As a result, in 1995 the British Standards Institution granted Rettig Heating an ISO 9002 quality certificate, and in 2003, ISO 9001:2000 and ISO 14001:1996 certificates. A team of inspectors constantly supervise the maintenance of the high quality of our heaters, and several times a year, British auditors conduct unannounced inspections of the Rettig Heating plants in Europe.
Rettig Heating Sp. z o.o., a company being the manufacturer of PURMO heaters holds all certificates and attestations that admit offered products to trade and use in the building industry. Documentation comprises PZH Hygienic certificates and Declarations of conformity with standards.
We additionally make available also certificates of conformity with ISO 9001.
