The Dutch cabinet is making smart hybrid heat pumps mandatory for many homeowners who replace their central heating boiler from 2029, it announced on Wednesday.
No need to glare at your boiler just yet: nothing changes until your current one is due for replacement. Housing Minister Elanor Boekholt-O’Sullivan (D66) set out the plan in a letter to parliament on October 7, delivering on a promise from the coalition agreement.
How much will a hybrid heat pump set you back?
Expect to pay roughly €8,000 for a model of about 4 kW, with a new boiler and installation included, according to RTL Nieuws. Your final bill will depend on who supplies and fits it, and on which pump you pick.
RTL puts the ISDE, the government’s subsidy for greener home upgrades, at about €2,000 per household. The exact payout depends on the type of pump, says RVO (the Netherlands Enterprise Agency), which guarantees a minimum of €500.
Lower subsidy amounts from 2027 are under discussion, and that prospect alone triggered a recent rush of applications. You can also take out a loan through the Nationaal Warmtefonds (National Heat Fund), and if you earn €60,000 or less, you won’t pay any interest.
Will you actually save money?
On paper, yes. The government says switching to a heat pump, hybrid or not, cuts the gas a home burns for heating by 65% on average.
For a corner house with moderate insulation, Kenniscentrum Duurzaam Leven calculates savings of roughly €600 a year, RTL reports.
And believe it or not, the leakier your home, the faster the pump earns its keep. “Strangely enough, houses that are poorly insulated, and so use more energy, earn back the cost sooner because they save more on gas,” Simone Tresoor, an adviser at the knowledge centre, told RTL.
Flat, monument or rental: does this apply to you?
If your home is linked to a warmtenet (heat network), or will be soon, the rule doesn’t apply. Things also get trickier for apartments, where there’s often nowhere to put the equipment, and for monuments, which require a permit that owners can’t always get.
The minister says the full list of exceptions is still being drawn up. Landlords are among the groups the cabinet is consulting, so renters will have to wait and see how they’re affected. Note that only owners living in their own home can currently claim the ISDE.
Why does it need to be smart?
Think of a hybrid as a tag team. The heat pump covers most of your heating, while the gas boiler handles hot water plus the moments when the house needs a lot of warmth fast, like on cold days.
Your electricity connection can usually stay as it is, but you may have to tweak some radiators or underfloor heating.
Then there’s the grid. The Dutch power network is packed, and grid costs are set to push up energy bills next year. Smart pumps run on software that times heating for quieter moments on the network or cheaper electricity, with the requirements spelled out in a Dutch Technical Agreement (NTA).
Haven’t we heard this before?
Yep. Back in 2022, an earlier cabinet planned to make hybrids compulsory from 2026, only for the Schoof cabinet to bin the idea, Reformatorisch Dagblad reports.
The minister sees 2029 as the soonest the rule could kick in, and the updated rules should appear around the middle of 2028, according to RTV Focus Zwolle. Hybrids are meant to bridge the gap to heating every building without natural gas by 2050, giving owners time to improve their insulation first.
