Solar Hot Water

For residential blocks of about fifteen or more stacked residential apartments, centralised gas hot water can be cheaper and space save than individual water heaters.
A typical gas centralised hot water system supplying residential dwellings includes:
one or more central hot water heaters, with corresponding gas meters
insulated piping to each apartment, with individual hot water meters.The total amount of gas consumed to provide hot water is split amongst the dwellings supplied.  Each dwelling’s gas consumption quota is calculated based on the amount of water flowing from the boiler to the dwelling measured by the hot water meter, and is reflected on an individual gas bill.
SolarLord commercial gas hot water systems are available in a host of options including hot water storage tanks, warm water valves, heat exchange tanks, solar pre-heating, circulating pump controllers and BMS take off points. 
Complete systems can be pre-assembled to wall mounting, free standing or skid mounted in our factory. By taking a modular approach, each system has been tested and can be easily transported and fitted into position, which means it requires connecting only on site.

Hydronic, or radiant floor heating is a method of heating a home, shop, or other building with the heat concentrated in the floor.

Six U tube collectors with two 450 litre solar storage tanks provide hydonic heating for a 250 sqm house in a Melbourne regional suburb.

1. Outer Tube
Allows light rays to transparently pass through with minimal reflection

2. Inner Tube
Special selective coating on outside of the tube contributes the highest thermal efficiency and good thermal stability.

3. Evacuated Space
Stops heat loss/emission to outside of the glass tube making these collectors particularly useful during cold and cloudy weather

4. Coating Surface
Absorbs maximum solar radiation to convert into heat efficiently

5. Cylindrical Shape
Sunlight is perpendicular to the absorber for most of the day.

6. Fin
Transfers the heat to copper tube without heat loss

7. Copper Conduction Tube
Passes the heat to the water/fluid inside the copper tube.

8. Barium Layer 
Actively absorbs the air to maintain vacuum of the two tubes

How does it work?

Transparently through the outer tube, the Sun rays perpendicularly strike the absorber surface coated on outside of inner tube. The surface of absorptive material absorbs maximum solar radiation and converts it into heat efficiently. Because the sunlight is perpendicular to the absorber almost all day the solar energy can be absorbed and transferred efficiently. The insulator built by vacuum space between the outer and inner tubes functions well to eliminate heat loss to the outside but only pass the energy to the copper tube inside of the inner tube. This smarter design and perfectly manufactured product is a great contribution to sustainable living.
