How will a Solar Water Heating system work with a Tankless Water Heater? Initial let us a take a peek at how solar heating works. Generally there are solar collectors that capture the sun’s heat and transfer it to some liquid medium. That liquid medium will be the new water used later or a special liquid that transfers the warmth through a heat exchanger.

The solar collectors can be created from totally different materials. Copper and Glass are common. If you study your car’s radiator you may see fins hooked up to a series of pipes. Here the engine’s heat is transferred through antifreeze or different liquid to the radiator. The radiator can then RADIATE the warmth to the surroundings and therefore cooling the engine’s cooling fluid. The fins provide added physical radiation space for faster cooling and smaller radiator.

Currently, Solar Water Heating works simply like that, only the method is reversed. The fins or other surface expanding area is used to capture the sun’s heat and heat the water or some other fluid inside it. All solar water heating systems have a storage tank and circulation system. The water is heated in the solar panels and then stored in a very storage tank that looks like the regular storage water heater tank. The solar tank is much higher insulated and retains the warmth better since it does not have a venting flue just like the traditional tank.

In a very direct solar system the water in the storage tank is then circulated through the panels to be heated when exposed to the sun and come back to the tank again. This technique will work while not a pump or with a pump, relying on the system’s design.

A temperature controlled mixing valve will then combine the water from the tank with fresh cold water to induce the required temperature that’s set to. There are numerous safety parts to manage the pressure and temperature in the panels and also the tank and prevent over heating of the components.

Combined with Tankless Water Heater

The tankless water heater’s computer invariably measures the incoming fresh cold water temperature and adjusts its gas burner therefore the set hot water temperature will be achieved. The measurement of the outgoing heated water and also the incoming water happens many hundred times a minute. The pc then regulates the gas offer to the burner and measures the burner’s efficiency and regulates the oxygen for optimum combustion.

The incoming water to the tankless water heater can be of any temperature, almost. The computer will normally vary the combustion from approx. five% to one hundred%. A easy example without thought of water volume is that if the new water temperature is about to 120 deg. F and therefore the incoming water temperature is at sixty deg. F the combustion would be set for 100%. If the incoming water temperature is a hundred and twenty deg. F then the combustion is about to zero% and the burner wouldn’t be fired up. The tankless water heater is in a position to “meet up with” the incoming water if it is approx. equal to its set hot water temperature but it CANNOT cool the water.

A solar water heating system will simply be used with a tankless water heater. It is one in all the most economical ways that of heating water. The outgoing heated water offer of a solar heating system can be the incoming water provide to the tankless water heater. Anytime the water is below the specified hot water temperature the tankless water heater would heat it to the set temperature and if already at that temperature it might simply “suffer” the hot water.

If such a system is designed and sized properly it can be run with a small tankless water heater that will act solely as an auxiliary heater to the solar system provinding hot water in cloudy days and be very cost effective and energy saving.
