Gaslijn

What Gaslijn does

Gaslijn (legal entity Gasservicebedrijf Gaslijn, DBA 'Gaslijn uit Haren') is an independent, owner-operated HVAC installation and service company based in Haren, Groningen, Netherlands, with a service radius of approximately 40 km covering Groningen, Hoogezand, Eelde, and Westerbroek. Founded in 1990 (per the company-history timeline; firmographic data carries 1985) and operating for over 30 years, the firm specializes in gas-combustion appliances and increasingly in sustainable residential energy. Its core offering is CV-ketel (central heating boiler) service — installation (ATAG, Intergas, Vaillant brands), preventive maintenance, and 24/7 emergency repair — augmented by a sustainable energy line (warmtepompen / heat pumps, zonnepanelen / solar panels, zonneboilers / solar thermal) and a duurzaam advies / subsidy advisory service. The company also sells an annual onderhoudscontract (maintenance subscription) bundling scheduled service with emergency support across boilers, heat pumps, and ventilation units.

The business monetizes through three streams: (i) recurring subscription revenue from maintenance contracts (€86–€218 per appliance per year, indexed annually, with a 10% multi-appliance bundle discount and VAT included); (ii) one-time installation fees for boilers, heat pumps, solar PV, and solar thermal systems, with manufacturer-backed 5–10 year parts warranties; and (iii) per-visit repair/emergency service fees with preferential rates for contract customers. GTM is a service-led field-sales motion: phone (050-5347788) and website contact forms reach a human employee (no automated menus), and approximately 10 technicians depart daily from a recently expanded Haren warehouse carrying an inventory of over 1,000 parts plus van-stocked essentials, enabling fast on-site response. Marketing is modest: an informational website, Facebook and LinkedIn pages, Google Analytics, and word-of-mouth.

Operational moat derives from a regulatory certification stack rather than from technology or scale: SCIOS (high-power >100kW installations), mandatory CO-certification (BRL 6000-25 / KIWA, required from early 2022 for gas-combustion work), VCA safety certification, KvINL quality assurance, and Techniek Nederland association membership. The firm is privately held with no external investors, no parent, no disclosed funding rounds, and no listed leadership team — consistent with a bootstrapped local-services business. Headcount is reportedly 6 in firmographic data while operational references cite 10 technicians, indicating a small owner-operated entity with field-heavy staffing.
