SB510-DOT Region 3 Mapleview

Department of Transportation requested for service, stated “Evaluate existing heating system and provide recommendations and cost estimates for repair/replacement.

The facility was built in the early 60’s with a small addition put on in the mid-90’s. Oil fired heating hot water boiler was installed in the early 60’s.

Based on the drawings, the heating hot water boiler is likely to be replaced because of the new addition and the age, so heat load calculation is needed to size the boiler.

Validate my answer with original design.

10% safety factor taken into account

New boiler should be sized up to about 941,000 BTU/HR (753.2/.8)

80% efficiency (worst case scenario)
