The installation costs will depend on a number of factors, the biggest one being the type of boiler you install. You can save on the installation costs by doing the work yourself, although most people will prefer to have the work done by a professional, for safety’s sake. You should always obtain several estimates for installation and check with the Better Business Bureau to ensure you’re dealing with a fully certified installer before you contract someone.
You can reduce the installation costs of your new boiler with federal tax credits. These are available on gas, oil and propane hot water boilers. However, to receive the tax credit, the installation must be on an existing home (not a new build), and the house must be your principal residence. The tax credit is 30 percent, up to $1500, of the cost, including installation. This credit can have a big impact on the overall cost of your project.
The installation costs on a wood boiler will generally run anywhere from $1500 to $3500. The variance depends on how far from the house the boiler is located, the type and location of both the water heater and furnace, and the appliances that are connected to the boiler (a pool or spa, for instance).
Other factors that can affect your cost include going around gas and water lines, or needing additional electrical wiring inside the house. Where there are few obstacles and the installation is relatively straightforward, expect to pay in the region of $1500 to $2000.
A wood pellet boiler has far lower installation costs and generally works out at between $350 and $550.
With gas boilers, the installation costs are different than for wood boilers. You should expect to pay in the region of $1000 since it’s a long, detailed job. Labor costs are high because installation can take up to 2 days. Unless you’re buying from the installer, you can reduce costs by having the new boiler delivered to the area where it will be installed.
If you do most of the installation yourself, call in a professional to fire up the boiler and adjust the carbon dioxide levels.
Combi boilers are much smaller and more efficient than others. However, that doesn’t mean the installation costs are any cheaper. Again, installation takes some time, so the labor costs inevitably go up.
The good news is that the installation can be completed within a day, and the installation costs should run between $500 and $800. Costs will often be at the lower end of this scale because it should only take one person to install a combi boiler.
