    As we bath late in the evening and need geyser to re-heat water for the morning pure solar geysers would not work for us.
    The mentioned heat pump is also priced at about R17 000. Also due to the low electricity use this unit can also run with sun power if a hybrid inverter with panels are used. This way heating during the day is close to free.
    Based on some comments the Sunsynk inverters seems to be a good choice from a value for money point.
    Hehehehe would love to get one of those but then have the "evaporator" side feed into air vents going into the home
    But then have a lever somewhere so you can change the direction so that instead of blowing in it blows out for winter

    Basically using the unit to both heat your water and cool your house because it is technically doing what a air con does when using it in winter

    That is actually quite a common practice in large systems. In a nutshell the heat generated by the freezer room is used to heat water for the geysers.

    Green Lantern Inn at Van Reenen has just such a system - DIY - with some help from ynw.

    I have also looked at the cool air blown into the house but the cowling and then a pipe through the roof tiles at my entrance would not look good. I would also want to use a butterfly/shutter to prevent blowing into the house in winter.

    I know
    The small ones they act as though it is not a option

    Add in that you would then also need to install filter system so you do not pump all the dust in
    Definitely more complicated thing to do

    As it is commonly installed close to a wall I guess there is less dust than in free air. Very easy to put filter material on the suction side and velcro pads to keep it from sliding off when no suction takes place. My evaporator hardly has a lot of dust stuck in it when I do a spray down. About zero insects sucked in.
