Product Description

   The working principle of preheating solar water heaters is primarily based on solar collectors absorbing solar radiation energy, transferring heat to water through heat exchange, and utilizing natural circulation or forced circulation to achieve continuous hot water supply.

   Solarway offers a range of high quality tanks designed especially for "Pre-heating". These tanks can be used in combination with existing electric/gas mains pressure water heaters, or even as stand alone low pressure hot water systems with the addition of electric elements or external gas boosting. 

    Ideal for use as low pressure thermal stores, the pre-heating solar hot water heater is available with the addition internal coil heat exchanger. 

 

Features:

   Pre-heating solar water heater provide mains pressure via a high efficiency copper / stainless steel coil heat exchanger located within the tank. Through the unique heat exchanger, cold water travels through the coil heat exchanger inside the water tank, it rapidly heats up and flows out with high pressure,providing an immediate supply of hot water.The hot water inside tank is only used for heat storage and exchange.
     1.Fresh hot water: the hot water are aways fresh. do not use the storage water.
     2.Pressurized System: water flows out with pressure
     3.Pressure endurance: Heat exchange coil can withstand 6-12 bar.
     4.Pre-heated system can supply instant hot water: overcome the disadvantage of traditional system, such as slow heating, long time waiting.
     5.High Efficiency: high efficient solar vacuum tube
     6.More affordable: Compare to heat pipe pressure system, it has a more affordable price.
     7.Eco-Friendly: renewable solar energy to heat water
