Model Number

YP58-1820

Features:

1) No water in the tube so it never crack easily and never fur up

2) Stand up to freezing below -50degrees

3) Needs only temperature difference, sunshine is unnecessary, high heat conduction
and will never hibernate

4) Ultra low temperature molecule vaporizing conduction (vaporizing point of the medium
in the pipe is -38 degrees)

5) Low heat capacity and fast warming-up, heat output power is above 120W , fast conduction can be measured by second and is 1000 times of copper, conduct heat effectively even under non-sunshine weather

6) Even one of the pipes is cracked, the machine works as well as usual because each pipe works independently.

7) Tri-layer vacuum protect heat from losing, good one-way conduction have effective heat preservation

8) Heat pipe is free from water flow, which ensures cleaner water

9) Heat pipe keep earth sediment away, realizes everlasting high heat efficiency

10) It an produce more hot water than the general types

11) All the merits listed above ensure low maintenance cost during the product life

Advantages of pressurized solar water heater then non pressurized solar water heater:
1) Solve the problem of non-pressure solar water heater’s zero pressure hot water output

2) Solve the problem of inconstant water thermoregulation caused by maladjustment of nature fall pressure of non-pressure solar water heater and cold water pressure change of tap water

3) The water capacity in water tank keeps constant in use in order to avoid the empty heating while the heat storage tank falling fetching water

4) The heat storage water tank seldom feed water to avoid repeat operating complicated water feed problems every day
