In general, payback times tend to be shorter for propane and electricity hot water systems and longer if you are currently relying on natural gas. Due to the magnitude of these factors of influence, it is impossible to offer one precise figure here. However, from our experience, results from our customers, suggest payback times from as low as 3.5 – 8 years for a solar hot water system with a design life of over 30 years.
