CIUS warmtepomptechniek

What CIUS warmtepomptechniek does

Cius Techniek B.V. (trading as CIUS warmtepomptechniek) is a Dutch specialized heat pump technology service firm headquartered in Dalfsen, Overijssel, Netherlands. Founded in 2003 by Harrold Hofsink as a sole proprietorship (eenmanszaak) and now operating as a private limited company, the firm has grown to a team of approximately 19 specialists focused exclusively on heat pump systems. Its portfolio spans the full ownership lifecycle of a heat pump: design, installation, remote monitoring, optimization, maintenance, and certification, with a customer base anchored by installation companies and heat pump manufacturers, and extended to private homeowners, schools, veterinary and healthcare facilities, and industrial sites.

The technical offering is built around two product categories: ground-source heat pumps (brine/water closed-loop systems using vertical earth probes or horizontal collectors with capacities up to 60 kW, and water/water open-loop systems typically starting at 100 kW) and air/water heat pumps in split, monobloc, or hybrid configurations. Differentiated capabilities include remote performance monitoring, building management system integration, and the ability to re-optimize underperforming installations — illustrated by a project at AW Materieel/Machinery where compressor runtime was reduced to 25% of prior levels. The firm holds BRL 6000-21 certification across all scopes, alongside BRL 100, EPBD-A, and EPBD-B certifications, which together authorize it to handle design, realization, maintenance, and municipal permit applications for ground-source systems.

Revenue is generated through a mix of one-time installation projects, recurring annual or biennial maintenance subscriptions with embedded emergency-service benefits, fee-based training programs (basic and advanced heat pump technology, BRL 6000-21 design and realization, management and maintenance), and professional-services revenue from certification handling. Go-to-market is regional and direct, anchored by relationships with Dutch installation companies and authorized service-partnership agreements with multiple heat-pump manufacturers. The company operates as part of the Vesting Groep, a Dutch network of more than 15 installation and climate-technology firms that provides cross-referral distribution and shared brand reach across the Netherlands.
