OHVAP

Venting system design and analysis tool for manufacturers and installers of all types of residential oil-fired appliances, such as boilers, furnaces and water heaters. OHVAP (Oil Heat Vent Analysis Program) performs a transient analysis of the flow and heat-transfer dynamics of chimney and power-vent systems, to guide the efficient and safe installation of new vent systems and the retrofit of existing systems.
