- Water is kept hot and ready
for use at all times in insulated storage tanks with
capacities ranging from 20-80 gallons.
- Cool water flows into the tank
to be heated by a pressure sensitive valve. In this process,
water is heated continuously through the tank storing hot
water.
|
- Water circulated through a
large coil is heated only on demand using gas or electricity.
- They take up much less space
than a Storage Water Heater.
- A possible concern with this
technology is the limitation on the number of fixtures that
can simultaneously use hot water. However, there is an endless
supply of hot water and standby losses are eliminated.
|
- Solar Water Heater's use the
sun's energy to heat water.
- Cold water is moved via a pump
from a water tank and travels through solar collectors in a
solar panel. In the process, it is heated up by the power of
the sun hitting the solar collectors. This heat is then
carried away from the solar collectors by the water returning
to a heated storage tank.
