How much does it cost to install a Navien NR-240A?

A typical installation should cost $400-$500 including the parts and the labour. Because the unit is direct vent (pulls the intake air directly through a hole in the wall, and exhausts the exhaust directly through the wall), installation of the venting is usually fast and easy. Be sure to spend a minute to research your local bylaws to make sure your contractor is doing it properly (many won't know or care). Things to look out for are:

1) Exhaust vent must be a certain distance from fresh air intakes or windows that open

2) Some intakes and exhaust pipes must be a specific distance from the gas meter

As for parts, you'll have some gas line (usually flexible), a gas line T, some minor plumbing to get water from where the old tank was to where the new tank is, and some plastic venting pipe. The venting pipe is usually Schedule 636. If we assume the typical parts are about $100, that would leave $300 for our plumber and labourer for 4 hours of work, or a combined rate of about $75/hours.
