    Efficiency of air source heat pump water cylinders

    Does anyone know the efficiency levels of the unvented hot water cylinders with a heat pump on top with vents to get the air in to it. I think I'm correct in saying a normal direct unvented cylinder will be 1kw of electric to 1kw of heat

    Air Source Heat Pumps

    I have been thinking of going on this course but my only reservation with it is reaching out to the right clientele, has anyone made this transition and started fitting these units? And if so, was it worth doing the course for the amount of work gained afterward?
