A client is considering replacing his heating system in an office building. Two systems are being considered. System A has higher initial costs but lower recurring costs. System B has lower initial costs but higher recurring costs. The client expects that this office building would be re-constructed 18 years later. The discount rate to be used is 10%.

	System A	System B
Initial costs	$500,000	$250,000
Recurring costs
Minor repairs	5,000 per annum	8,000 per annum
Fuel	20,000 per annum	25,000 per annum
Major repairs	35,000 every 10 years	30,000 every 5 years

Please conduct a cost-in-use study of the above two systems covering both initial and recurring costs until 18 years after replacing and advise which of the above methods is the more economical option for the client.
