I guess some method would be nice to have that prevents heat escaping during the night as if pipes are at the roof and tank is below the roof, then it can start circulating by it's own, despite having pump. There was bit differences from pump to pump with this, but maybe as simple as manual valve to close after day and open at the morning would be enough good for that, some fancy electronic brain controlled valve would of course be easier, but that is always more cost and bother.
