ACV

What ACV does

ACV International NV is a Belgian engineering and manufacturing company founded in 1922 that designs, produces and distributes solutions for domestic hot water generation and space heating across residential, commercial and industrial end-markets. It is a subsidiary of Groupe Atlantic, a diversified European heating and hot water group, with legal headquarters at Oude Vijverweg 6, Dworp, Belgium. The company operates regional entities and offices across at least eight European markets — Belgium, France, United Kingdom, Germany, Italy, Spain, Poland and Czech Republic — and claims product availability "on every continent" through distributor networks.

The company's product portfolio is built on a proprietary Tank-in-Tank stainless steel architecture (a primary heating circuit surrounding a secondary DHW storage tank) combined with total condensing technology that condenses in both heating and DHW modes, a self-cleaning stainless steel heat exchanger that removes the need for anode protection, and the ACVMax electronic control platform supporting OpenTherm 3.0, Modbus and 0-10V signals. Flagship product lines include the HeatMaster Evo 2 and HeatMaster N (combined condensing boilers with integrated water heating), WaterMaster Evo 2 (standalone condensing DHW producer), the Smart and Smart ME multi-energy Tank-in-Tank cylinders, the E-Tech series of commercial and industrial heat exchangers (M, P, S, W), the HeatMaster and WaterMaster 20% hydrogen-ready lines, and the Nextra heat pump water heater. Documented performance specifications include combustion efficiency up to 98.1%, Energy Class A heating, peak DHW flow up to 900 L/10min at 40°C, and continuous flow up to 3,402 L/h for HeatMaster 120 TC.

Revenue is generated through a manufacturer-distributor model in which ACV sells hardware (condensing boilers, water heaters, cylinders and accessories) exclusively through certified professional installer networks supported by regional sales representatives covering defined geographic territories (eight named UK reps across Scotland, two England/Wales zones, Midlands, two London/Home Counties zones and the Channel Islands). Specification is driven through architects, consulting engineers and facility managers; the company supports channel demand through the ACV Academy installer training program, country-specific websites with technical documentation, and an installer-locator tool that routes end-customers to channel partners. Pricing is channel-only and not publicly disclosed. Customer references span hospitality (Radisson Hasselt, Crieff Hydro, Titanic Hotel Belfast, Hotel Arłamów, Schloss Eckberg), healthcare (Quirón Ziekenhuis), sports facilities (Patro Eisden, Power8 Stadium RCD Espanyol, Regal Padel Club Zaragoza), residential developments (Osiedle Zielona Dolina) and emergency services (Cleveland Fire Brigade).
