1. SOLAR COLLECTOR FOR WATER AND SPACE HEATING
Tariq Mansour

2. Solar Collector and Storage Tank
Glazed, insulated box
series of pipes inside
Retains radiation which is converted to heat
Storage tank which stores water

3. Passive vs. Active Passive Active
Utilizes natural forces(gravity, convection currents)
Batch
Thermosiphon
Active
Uses electricity to pump water throughout the system
Direct
Indirect
Drainback
(Solar Water Heater)

4. How does it work? Direct Systems:
Collector heats water and hot water rises to tank
Cool water descends to collector and is heated
Indirect Systems:
Anti-freeze is heated and goes on to heat water, the two never make contact
Drainback systems are better suited for areas which experience cold weather, distilled water is used as a heating fluid and is stored inside

5. How does it work?(cont.)

6. Benefits Up to half of annual electricity bill is saved
Infrequent maintenance necessary
Clean energy, no emissions
Government grants for up to 30% off
(Solar Hot Water)
(Solar Water Heaters)

7. Drawbacks Large payment upfront, prices range from $1500-$3000
Potentially negative factors include:
Climate
Home orientation
Some systems prone to poweroutages
Building regulations
