• I’m just struggling to see how going via how much stuff costs and the what the grant actually gives you in term of like for like. Considering ASHP uses a lot more kit than stay a combi system.

  • I detailed what each quote entailed a few posts up.

    A system boiler needs the same amount of gubbins as a heat pump (UVC, diverters etc).

    Again, don’t forget about the £7.5K grant!

    How much would you quote for a complete Vaillant system boiler with 250l Vaillant tank and weather compensating sensoCOMFORT controllers, entirely new plumbing from scratch etc?
