Description
Non-pressure solar water geysers always work with an assistant tank for automatic water refill into main storage tank. The working theory is similar with flush lavatory, with a float ball valve inside assistant tank to control water filling, the assistant tank is usually installed on top of main solar water heater tank, with a stainless pipe connecting each other, when float ball descends, the valve connecting with float ball opens to let in city water, when main tank is full and water rise in assistant tank, the float ball rises to shut the valve and water refill stops.
Assistant Tank For Solar Water Geyser is specially designed for non-pressure solar water heaters, it works mechanically without manual operation, avoiding water overflow when manual water refilling. With an assistant tank the solar water heater is always full of water.
