Other main characters.

1) Long operating life: Using the advanced stainless steel/titanium
    metal water heat exchanger, which resists the erosion from chlorine
    in the water, creates a longer lifespan.
2) Economical and high-efficiency: Using heat pump technology, compared
    with other ordinary hot water equipment (for example, combustion oil
    boilers, combustion gas boilers, electronic boilers and so on), it
    reduces operating costs by 65-80%, In addition it creates very little
    pollution.
3) Bright design, easy installation and replacement: Unit design
    separately for main model and water unit model, with water unit
    inside, avoiding freezing in the winter. The unit is remarkably
    compact, with pump and flow switch inside.
4) Advanced controlling: It is extremely easy to control. The swimming
    pool heat pump unit is in the room, because of the mini-computer
    intelligent controlling .
5) Safety: Water and electricity are insulated, no open fire, no creepage.
6) Quiet: Using the high-efficiency, low sound rotary or scroll compressor,
    low noise fan, high quality pump, creates an extremely quiet machine.
7) High technology heat exchangers: Due to brand and heat exchanger, it
    runs more efficiently.
