Do I Need a Permit to Replace a Water Heater? in Nederland
Replacing a water heater requires a plumbing permit in most US jurisdictions and a notification or licensed-installer certification in the EU. Gas water heaters add a separate fuel-gas permit requirement. Tankless and heat-pump units may require additional electrical permits when service amperage changes.

Country-specific detail
Dutch water heater replacements typically don't require a building permit when the unit is replaced in place, but gas work must be performed by an erkend installateur with the Kiwa quality mark. Switching from gas to a heat-pump boiler often qualifies for ISDE subsidies. Combi-boilers handling DHW + central heating fall under SCIOS Scope 1/2/3 inspection rules.
