Install Boiler questions, answered by experts

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

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.

Always consult your manual for specific pressure numbers. Many expansion tanks come pre-pressurized at a specific PSI range, anywhere from 12 to 40 PSI, designed for a range of home boilers. You should not have to pressurize an expansion tank yourself, only the boiler system. If your system has a tank that needs to be manually pressurized, this is generally a job for professionals and their tools.

A home radiator lasts anywhere from 15 to 20 years with proper maintenance. If your unit is approaching the 15-year mark, it’s a good idea to inspect your system and consider upgrading the radiator to a new one. Older models are less efficient over time compared to newer, energy-efficient radiators.

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.
