13. Payback time Example: Adding silver reflectors behind radiators costs £25 and saves £50 per year. Payback time is the time it takes for the cost of installing insulation to be equalled by the savings made from reduced energy costs. = 0.5 years payback time (in years) = cost of insulation saving each year payback time = 25 50 = 6 months

14. Calculate the pay-back time for each method: Why is double glazing so popular if the pay-back time is so long?
