have lived with a cistern for 25 years. There are definitely
issues. Collecting melting snow is one. However, once it
melts and drains into the tank that is in the ground, it is heated up to ground
temperature. If you bring that water into the house in an un-insulated
tank, it would be heated up to room temperature, cooling down the house in the
process. Then boosting the temp instantaneously becomes more
efficient. This is tank of water is another source of thermal mass.
Although when consumed is another heat load for house heating system. In
the summer, it is a slight benefit for cooling the house. <?xml:namespace

<DIV><BR></DIV>Clark: Not in NYC when their reservoirs fill with snow melt in
the springtime and tap water approaches 35F. That's when a 2.25 gpm shower @
105F needs a 70F rise; requiring about 70/3 = 23kW; a 50 amp heater yields
about 12kW worth of hot water.
