Install Boiler questions, answered by experts

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

You can replace baseboard heaters with many other types of HVAC systems, including forced-air furnaces, hydronic heating, and heat pumps. Each one has its advantages and disadvantages, so the best choice for you will depend on your budget, preferences, and the design of your house. If you aren’t sure which option is right for you, ask an HVAC pro for guidance.

If your boiler is 20 years old, it’s time to get a new one. Although it may seem to be working fine, it’s likely eating up more fuel than it should. Also, compared to a brand-new boiler, one that’s 20 years old is probably not working as well. When you get your new unit, you’ll notice that your home is heating more quickly, and the heat is consistent throughout all the rooms.

The main difference between an outdoor wood furnace versus an outdoor wood boiler is what each appliance is heating. An outdoor wood furnace burns wood to create heat, which warms the air and moves it through the ducts in your home. An outdoor wood boiler uses the heat from burning wood to warm water, which goes through pipes to radiators in the home.

Generally speaking, an oil furnace is safer than a gas furnace for a number of reasons. Both types create carbon monoxide, with the potential for deadly leaks, but it's easier to detect an issue with an oil furnace because you smell the problem almost immediately. Also, oil furnaces don’t connect to a pipeline, reducing the chances of a leak in the first place. Finally, heating oil is not combustible, and natural gas is, so there’s no chance of an explosion and a reduced chance of a fire with an oil furnace.
