Cost in the Netherlands
Typical install: €1,500–€4,500. Dutch apartments have used tankless (geyser) widely for decades. Modern condensing units (HR ketel) hit 95%+ efficiency. ISDE subsidies don't typically cover tankless alone — they cover heat pumps and hybrid systems.
What affects the cost?
- Venting — gas units need stainless flue or PVC for condensing models
- Gas line upgrade — many tankless units need 3/4" gas line (vs 1/2" for tanks)
- Electrical upgrade — whole-home electric tankless may need a 200A panel
How to save
- Right-size, don't oversize — bigger tankless = bigger gas line + more $
- Annual descale — extends life and protects warranty
- Stack 25C credit + utility rebate — most homeowners miss the utility rebate
