1. Solar nova scotia case study: Solar Thermal Halifax

2. Project Scope Solar hot water combination system
Domestic hot water
Space heating
Installed 8 solar collectors on roof
Good roof pitch (34.5 deg or 8.25/12 slope)
Orientation close to south (152 deg true south)
Used locally manufactured equipment
Thermo Dynamics flat plate collectors

4. Project is Part of a Holistic Approach
Energy Efficiency
Greenest thing to do
Best return on investment
Reduce Energy Consumption
Turn down the thermostat
Put a sweater on
Renewable Energy Sources
Solar hot water system

5. Project Costs (Installed April 2009)
Initial Capital Cost $ 22,000 Rebates $ 4,900 ( 22% ) ============================= Net Capital Cost $ 17,100 ( 78% )

7. Fuel Savings Pre Solar 2305 With Solar 931
===============================
Fuel oil savings ( 60% Reduction! )
Based on historical average yearly home heating fuel oil consumption in litres
