150L Colored Steel Outer Tank Vacuum Tube Residential Heat Pipe Solar Water Heater
Main Features:
(1) Glass vacuum tube solar collector, high temperature,antifreeze,vacuum insulation
(2) Copper heat pipe,Start up quickly,transfers heat quickly, low start-up temperature,low temperature resistant
(3) Food-grade stainless-steel SUS304 2B inner tank,full-automatic welding technology,under the protection of magnesium rod,it can increase of service life
(4) High pressure polyurethane foaming insulation,as the prefect density and the thermal conductivity coefficient is small, so it can provide effective heat preservation
(5) Gravity assisted heat pipe, unilateral heat transfer,high efficiency,low heat loss

FAQ
(1). How do I protect my solar system during subzero temperatures?
If you have a system that is operating in areas with subzero
temperatures then freeze protection must be implemented.
The easiest means of preventing freezing is to use a controller with a low temperatures setting.
So when the manifold temperature drops below a certain pre-set temperature (5°C/40°F), the pump will circulate, warming the collector with water from the bottom of the storage tank.
The pump will not run continually, just periodically, the frequency of which will depend on the outside temperature.
In extremely cold areas, a closed loop using a glycol/water mix may
be appropriate.
(2). Will water be heated on a cloudy day?
Yes.
Although the heat output of the solar collector is reduced on overcast days it will still be able to provide heating.
If it is a heavily clouded day or raining, then more gas or electric boosting may be required to maintain water at the required temperature.
This system will be automated so you don't have to worry about running out of hot water on a rainy day.
