What WTH | Klimaat waar je op kunt bouwen does

WTH Vloerverwarming B.V., trading as WTH | Klimaat waar je op kunt bouwen, is a Netherlands-based manufacturer of underfloor heating (vloerverwarming) and underfloor cooling (vloerkoeling) systems, founded in 1969 and headquartered in Capelle aan den IJssel. The company designs and produces its product portfolio in-house in the Netherlands, with flagship offerings including modular floor heating/cooling systems, the UMR2 smart regulator for per-zone post-regulation, the HT-S district-heating distributor (stadsverwarmingsverdeler) for connecting buildings to district heating networks, and a newly launched line of modular distributors (modulaire verdelers). WTH holds ISO 9001, VCA, Veiligheidsladder niveau 3, and CO2 Prestatieladder niveau 5 certifications, and operates as a wholly-owned subsidiary of TBI Holdings B.V., a Dutch construction and engineering conglomerate.

The company serves the Dutch construction sector on a project-based, B2B basis, primarily targeting new-build residential developers and housing corporations, with selected references in commercial and cultural buildings (e.g., Fenix Museum Rotterdam). Notable contract wins include Woontorens Grotius (655 homes), Zaanse Helden (607 apartments), Knightsbridge Hyde Park (406 apartments), KJ Plein (396 apartments), De Schaloen (307 apartments), De Nieuwe Defensie (291 apartments), SAWA (109 apartments), and HAUT Amsterdam (tallest wooden residential tower in the Netherlands). Distribution is via a direct sales force of account managers who engage projects from the design phase, supplemented by a webshop for existing customers and a partner network of installers, total-concept collaborators (B&I Vloerisolatie for floor insulation, Konnected for smart building integration), and intra-group TBI companies.

WTH's business model is hardware sales: revenue is generated through the sale and project installation of modular climate systems, with project-specific quotations rather than disclosed list pricing. The company emphasizes full lifecycle support from design through aftercare, certified installer training, and bundled "total concept" solutions combining heating, cooling, insulation, and smart controls. Geographically, WTH is exclusively Netherlands-focused, with no disclosed international expansion, no venture or private equity funding history, and no publicly available revenue figures.

Direct peers

• Rehau: German polymer and building solutions provider with a strong floor heating and cooling portfolio. Competes with WTH in European residential hydronic heating, including modular systems and controls for new-build projects.
• Uponor: Finnish global leader in underfloor heating and cooling systems for residential and commercial buildings. Directly comparable to WTH in product offering (hydronic floor heating/cooling) and target market (residential new-build developers and installers).
• Danfoss: Danish global supplier of heating controls, district heating solutions, and HVAC components. WTH's UMR2 controllers and HT-S district heating distributor directly compete with Danfoss's smart heating and district-energy product lines.

Broad incumbents

• Alfa Laval: Global supplier of heat exchangers and district heating/cooling equipment. Comparable to WTH's HT-S district heating distributor line for central-plant and network-connected residential projects.
• Daikin: Global HVAC and heat pump giant with growing presence in European low-temperature heating. Competes with WTH for primary heating equipment selection on Dutch residential developments decarbonizing away from gas.
• Bosch Thermotechnology: Major heating-systems manufacturer (heat pumps, boilers, controls) operating across European residential markets. A broad incumbent that competes with WTH for spec-in on Dutch new-build residential projects, especially as heat pumps scale.
• Honeywell Building Technologies: Global building automation and HVAC controls incumbent. The UMR2 controller sits in a similar product space as Honeywell's residential and light-commercial smart heating controls, though WTH serves a narrower Dutch new-build niche.
• Mitsubishi Electric: Large HVAC and building systems manufacturer active in European residential heating and cooling. Overlaps with WTH on integrated climate solutions for new construction and renovation projects.

Others

• Thermaflex: European insulation and HVAC pipe-solution supplier often co-installed with floor heating systems. An adjacent ecosystem participant whose products frequently accompany WTH systems on Dutch residential projects.

Regional players

• Vasco (Arbonia Group): Benelux-focused heating solutions brand offering radiators, underfloor heating and ventilation. Closely comparable to WTH on geography and product mix in residential climate systems.
