How much of my solar hot water needs can be covered with evacuated/vacuum tube and flat plate technologies?
Generally, 50% of hot water heating needs can be met for a typical 4-person household year-round. Hot water accounts for approximately 20-25% of a typical energy bill (more for electric heaters). Systems will vary in their production in winter conditions and temperature of pre-heated water will depend on the sun and the system. Contact your supplier for more details on specific products.
