whether it is available for hot water, hot tubs?
right, kettle, tub and so on.... Your entire house by connecting with almost any existing heating system such as: forced air (water to air heat exchanger), in-floor radiant heat (plate exchanger with existing boiler), water heater (side arm/shell and tube water exchanger), etc. You can heat a pool, a greenhouse, a garage, a workshop and you can heat multiple buildings at the same time.
