Installatie- en servicebedrijf De Haan

What Installatie- en servicebedrijf De Haan does

Installatie- en servicebedrijf De Haan B.V. is a privately held Dutch installation and service company founded in 1967, headquartered in Oosterwolde, Friesland. It installs and maintains central heating boilers (CV-ketels), heat pumps, solar PV systems, home batteries, air conditioning, electrical installations, and renovation work (bathrooms, plumbing, roofing) for residential homeowners and a smaller base of business customers across approximately 14 municipalities in Friesland. Product brands include Nefit and Intergas for boilers, with hybrid and full-electric heat pump offerings (Intergas Xtend 5 split priced at €4,325) plus solar thermal (zonneboiler) solutions delivered via a long-standing partnership with Harko Rutgers TOP-ZON. The company is KIWA-certified (since April 2023 under tightened Dutch rules), VCA-certified, CO-vrij certified, and a member of Techniek Nederland, the Dutch installation trade association.

Revenue is generated through a mix of one-time installation project fees (e.g., €2,099 for a complete combiketel CW4 including installation and flue gas exhaust), hardware sales on solar and heat-pump systems, and recurring Gasservice maintenance contracts priced at approximately €15 per month that bundle 24/7 emergency response, waived travel costs, and 18-month inspection cycles. Customer acquisition is sales-led and direct: phone (0516-43 17 27), email ([email protected]), website contact forms, social media (Facebook, X, LinkedIn, Pinterest), and word-of-mouth referrals within the Ooststellingwerf region. The company won the Techniek Inclusief Award 2026 from MKB Nederland on 5 February 2026, presented at the VSK trade fair before Minister Mariëlle Paul.
