    Insulation Spec is number 1.

    Then you will have to get like for like prices and compare them. Balance the electricity costs of heatpump against the woodchip costs, bearing in mind future increases and storage.

    The heat pump will be cheaper to run if installed correctly with more certainty of fuel supply also.
    Another thing that people never consider when running a wood chip/pellet burner is the electrical cost of running the auger or vacuum system to feed the burner which can be significant. Add this to the cost of the burnt fuel and the running cost per year would be quite a bit higher.
    Then you have the maintainence of cleaning out etc that you don't have with a heat pump.

    Air to water systems could be worth considering,My brother has 3 houses built this year with this heating system

    Air to water should be the last choice when it comes to heatpumps. Groundsource are far more efficient and have longer lifespans. I'd only look at air source when you've exhausted the other options of have an small property like an apartment
