    "The Dutch government intends to ban new fossil fuel-centric heating system installations as of 2026, while introducing the mandatory use of heat pumps or connections to heat networks"

    Although they're allowing electric-gas hybrid boilers, and there's an exemption for homes that are not suitable, or that will be connected to another alternative to natural gas in the short term (for example, a heat network)

    Unlike the UK's supposed plans, their also banning replacement gas boilers from the same date, not just for new build.

    According to the original press release, industry will be opening 3 new heat-pump factories, plus centres in every region of the country, and they'll be developing training courses, assessment tools and quality standards. They seem to be taking this rather more seriously than the UK.

    This seems like a strange idea. Is it a boondoggle? It sounds a bit like hybrid cars - duplicate the engine, adding lots of extra complexity, to what purpose?

    But full marks for getting on with the job.
  1.  
    I guess an electric-gas hybrid boiler is equivalent to a gas CH system with an electric immersion DHW cylinder - it's about having high kW gas heating available for peak times while taking advantage of off-peak lower-kW electricity for storable heat, possibly at lower off-peak prices than gas (in future!).


    Technically banned in the UK by the "primary energy" rules in new BR/BS that prohibit us switching demand from gas to direct-electric - going in the wrong direction IMO!

    But it does sound a fig leaf, like the "hydrogen ready" gas boilers being marketed in UK.

    I suspect hybrid heat pumps is going to become a thing here too. Grant sell a hydrid with oil and I think you can get them with gas from Vaillant, Daikin etc. In some ways this could go some ways to overcoming the significant psychological barriers to pure heatpumps as well as dealing with some of the current drawbacks in retrofit and also have a place in less well insulated homes. I haven't looked at the SCOP data at all but will be interested to know more.

    What is the average usage in Holland? Just wondering what the impact will be in terms of cost?

    I suspect the average consumption is lower than UK so the impact of the state forcing increased costs on the individual is lower compared to the UK.

    As ever though, the well off will benefit, the less well off will suffer.

    Just looked it up:
    - 79% of homes with an EPC used mains gas central heating in England & 78% in Wales in March 2021
    - 89.5% of homes in the Netherlands used gas for heating at the beginning of 2019 (and about 9.5% on district heating, with about 1% on electricity).

    In Netherlands new build, 64% of new homes are heated by gas. Couldn't spot a figure for the UK.

    As for funding, there's a direct subsidy averaging 30% on heat pump installation + zero-interest loans from the Heat Fund for those on low and middle incomes, 2.5% to 2.9% APR tax-deductible for others (not just for the heat pump, for other energy-saving measures too, up to €65,000, without an upper age limit).

    It seems not. Perhaps it's just the UK that treats people that way.

    I was thinking of consumption not % of homes on gas. i.e is the climate, quality of insulation etc appreciably different. The more gas you currently need to use, the greater the amount extra you will have to find to run a HP.

    Yes, how the UK does it is totally FUBAR.

    My experience is that any 'subsidy' or 'allowance' is absorbed by inflated costs from the installer. However, you still need to be able to pay for the other 70% and the increased running costs. The argument is that you'd have paid that for a gas boiler probably. Just replace my boiler with one with a 13 yr guarantee so hopefully I won't have the problem for a while.

    In effect my DHW system is now hybrid, using PV diversion, else topping up from the grid when low carbon, else falling back to gas if need be.
