VACUUM TUBE COLLECTOR - ADVANTAGES

solar water heating system

1. Heat absorptions from the infrared rays of solar radiation instead of the visible light rays, so during winter and cloudy days, the system absorbs infrared rays as usual.

2. Heat absorbing surface is always perpendicular to sunlight because of spherical collectors 3. Heating continues till late evening

3. Heating continues till late evening

4. It gives 10°C higher temperature of hot water in winter & Cloudy days.

5. The vacuum inside the collector tubes vastly reduces overnight heat loss

6. Salt or scale formation when using hard water will be reduced

7. Scale deposits slide off the smooth glass walls to accumulate at the bottom from where they can be easily removed.

8. Installation of the system is very easy

9. Area required for installation will be very less

10. Incase of damage to the collector tubes, individual tube can be replaced.

FLAT PLATE - ADVANTAGES

Best price water heaters

Benefits

Heating from infrared rays of solar radiation

Greater absorption area per day

Better performance in winter & on cloudy days. Up to 10℃ higher temperature

Maintance free, easy to clean

Compact size - low height & lesser space required for installation.

Installation Requirements

Unobstructed sunlight on a flat or slopping roof

Shadow-free area

Close to the bathrooms to avoid long piping & heat losses

A water tank at a minimum of 2.5m (7 ft) above roof level

Flat plate collector with copper fins coated in black for maximum absorption of solar radiation and effective heat transfer

Pressure pump compatible 5 bar pressure rating
