Working principle of pre-heat solar water heater:
1. The high quality vacuum tubes absorb the solar ultraviolet ray
and visible light; then heat the cold
water in the vacuum tube.
2. The hot water rise in the top of the water tank, and the cold
water sink to bottom then heat
by solar collector. So the whole system is always circulating
continuously. The water we use that
is in the copper coil, not in the water tank, the tap water connect
to the copper coil directly, the hot
water in the water tank exchange the heat with the tap water in the
copper coil
3. The Assistant water tank can perform the water supply
automatically, the water in the tank is
not sufficient, the electromagnetism valve will open its valve, the
tap water flow in the water tank,
if the water is full, it will close the valve automatically
4. The whole system can endure high pressure according to the
pressure-bearing technology
1. Packing: Standard export carton with foam or wooden box, Wooden
Box Packing for Sample
2. Shipping: 7 days for sample, 15 days for 20/40 container.
3. MOQ: 20'GP container (Sample is available)
4. Warranty: 10 years guarantee for whole set solar water heater
5. Port of departure: Shanghai or Ningbo
6. Supply ability: 8000 sets per month
Competitive Advantage:
1. We get instant clean and pressure hot water from copper coil
outlet;
2. Simple structure with very easy installation and pipeline
connection;
3. With copper coil exchanger we do not need to locate the solar
water heater at the house top;
4. PASSION argon-arc welding and in-house testing ensures a long
lasting storage tank without any leakage problem;
5. PASSION makes a high-density integral PU insulation for the tank
with heat preservation as long as 72~80 hours;
6. The solar vacuum tube is made of high borosilicate glass with
stable performance and no blasting problem for 15 years;
7. The support frame is designed for slope and flat roof
installation, aluminum alloy with stainless fastener has no rusty
problem;
8. PASSION pre-heat solar water heater can be equipped with
assistant tank and electric heater to make an automatic-operating
system;
9. We install sample solar water heater for every order before
delivery to ensure no mistakes or missing parts for customers.
