Install a Gas Wall Heater | |
To install a 25,000 BTU gas heater a plumber will charge about $600; you can do it yourself for the cost of the heater, about $450, saving 25 percent. Installing the heater is a straightforward project, but it does involve cutting a sizable hole in the wall behind the unit to accommodate the vent/air intake. This double-walled pipe extends through the wall. The larger diameter outer pipe draws in air from the outside for combustion, while the inner pipe vents the heater. You have to run a gas line to the heater, which can be especially challenging if you live in a brick house. You'll need a building permit for the job, another good reason to hire a contractor instead of doing this one yourself. |
