PRODUCT DETAILS
6000L solar water heater overview
Nowadays, hotels, apartments, fitness centers, spas, factories, schools, hospitals and other public places need to use a lot of hot water every day and energy expenditures account for a large part of the cost.
One-time investment in solar heating can recover investment costs in 2 to 4 years. Solar heating system can be used for 15-20 years, so it is obviously to see the fixed income in the future.
Solar heating systems are becoming popular in central heating systems.
Riwatt 6000L solar water heater system is mainly designed for central heating projects of 20 persons or more. The larger the project, the more obvious the effect of energy saving and cost reduction.
6000L solar water heater structure
Riwatt 6000L solar hot water heating system consists mainly of hot water storage tanks, solar collectors, solar controllers, circulation pumps, expansion tanks, valve fittings and piping.
6000L solar water heater design principles
The following factors should be fully considered when we design the right solar system
Initial temperature of water
User request on water temperature
sun insolation in the city where the project is located
According to the sun insolation in winter, increase solar collector area
According to the sun insolation in summer,reduce solar collector area
Solar collector and tank installation location
Original heating equipment utilization, connection and intelligent control
Design of backup heating systems
