How does the Solar Hot Water System work with tankless on demand water heaters?
Savings are even bigger for those with electric water heaters. If you plan on purchasing an on-demand system, call the manufacturer to make sure that model is compatible. from Manny Bade of Globe Solar… A. The concept of tankless water heaters (on demand hot water heaters) is that the water is heated not in a tank but directly through a high velocity heaters that burns gas instantaneously consuming tremendous amount of gas in a very short time. Our solar water heater is installed before the tankless water heater in the same way it is installed before a conventional hot water tank. When water gets into your house, it is at a temperature of 4C in wintertime and 10C in the summertime. Whether it is heated by tankless or conventional tank, it takes the same amount of gas to heat the water from 4 or 10 Celsius up to 50 Celsius. When we use solar water heaters, the sun pre-heats the water up to 30C so that the water heater (tankless or conventional) will need to heat it for just 20C, thus
