Jon has 1200 ft2 of roof in his home in pittsburgh, pa (hdd = 6,000). he is considering upgrading the insulation from r-16 to r-22. the estimate from the contractor was $578. his home is heated with natural gas. last year, the average price he paid for natural gas was $12/mcf. assuming an afue of 82.9%, how long will it take jon to recover his investment? (5 points)

1.6 years

Explanation:

To find out how long will it take john to recover his investment we will use following formula.

Years to recover = (IcxRfxRixEff) /(Ecx[Rf-Ri]xHDDX24)

Where,

Ic = cost of insulation in $/sft

Rf = final value of R

Ri = Initial value of R

Eff = Efficiency of heating system

HDD = heating degree days/ year

24 = multiplier to convert HDD into 24 hrs/day

Ec = Energy cost

Years to recover = (578x22x16x82.9)/(12x[22-16]x6000x24)

Years to recover = 16866502.4/10368000

Years to recover = 1.6
