Non-pressurized solar water heater


Non-pressurized flat plate solar water heater

SN-FT
1.Elegant and smart appearance, easy installation.
2.Reliable electric back-up with protection against dry heating and thermal cut-out.
3.Easy operation and intelligent control.
4.Stainless steel inner tank SUS304 for good anti-corrosion.
5.With high quality flat solar collector with long service life.
6.Polyurethane insulation with good heat reservation.
7.Totally copper flow channels achieve low defect rate and easy maintenance, long service life.

Working principle:
Under normal operating conditions the potable water within the potable storage tank
is heated by the solar collectors. For example, in an close circuit system where the
household hot water is in the collector circuit, cold water is pushed downwards via the long external pipe from the storage tank to the bottom of the solar collector. As the water is heated in the absorber by the sun, it rises to the top of the collector then travels through the short external pipe into the storage tank.

Description

                   

 

Product features:
1.Non-pressurized water storage tank can supply water automatically,so that can keep the water tank always be filled.
2.it is suitable for the district that near the equator, and was specially designed for the low latitudes region.
3.all-glass vacuum tube, high temperature,vacuum insulation.
4.Food-grade stainless-steel SUS304 2B inner tank,full-automatic welding technology,under the protection of magnesium rod,it can prolong the service life.
5.High pressure polyurethane foaming insulation,as the prefect density and the thermal conductivity coefficient is small, so it can provide effective heat preservation
6.The outer tank adopt color steel plate,and it has good double anti-corrosion function
