i have an empty house in a location that freezes up.
i am going to buy a couple thermostats for heaters to keep the pipes from freezing.
to reduce the amount of heating needed, i am going to put around 100 gallons of water in water bottles to keep warmth from the daytime sun.
has anyone done this for their greenhouse?
based on looking up some tables, the heat capacity of water is about 1000 times that of air (by volume) at an altitude of 5000 ft.
the house is about 26,000 cubic feet of air space.
so 26 galloons to hold equate the heat capacities.
100 galloons would be 4X higher.
i am going to use black plastic under the water bottles to absorb solar heat...
also aluminum foil under the water bottles to help thermal flow between the water inside the bottles and the room air...
