Debreceni Hőszolgáltató Zrt. (Debrecen Heat Supply Company) plays a central and caring role in Debrecen’s daily life, quietly ensuring comfort and warmth for thousands of homes and businesses across the city. With a strong heritage and deep roots, the company delivers reliable district heating and hot water service to over 32,000 residential and approximately 1,400 commercial and other users, embodying the spirit of service and responsibility.

Heat Supply is committed to making essential services as convenient, transparent, and green as possible. Through Zafír Portal, users can manage accounts, view or download documentation, opt in for e‑bills, report meter readings, or submit other requests—all online, safe, and time‑saving. Technical service and system maintenance are handled with care, including strict scheduling: major works on private systems are carried out outside the heating season to minimize disruption.

Beyond just providing heat, Heat Supply sees itself as a partner to the community. Whether helping households feel cozy on a cold winter morning, assisting businesses in maintaining efficient operations, or offering responsive support at any hour—especially in emergencies via their 0‑24 fault‑reporting line—Heat Supply blends technical expertise with neighborly attention.

In Debrecen, where climate and comfort go hand in hand, Heat Supply is more than a utility company—it is a cornerstone of modern urban life, committed to reliability, sustainability, and customer‑centred service.
