What Are the Signs That It’s Time to Replace My Boiler?
There are several indicators that it might be time to consider a boiler replacement—such as inconsistent heating, unusual spikes in energy bills, odd sounds like banging, whistling, or gurgling, leaks, or fluctuating water pressure. As boilers age, they typically lose efficiency and can cost more to operate. If you’re frequently calling for repairs or dealing with unreliable heat, switching to a newer, energy-efficient boiler may help you cut costs and improve comfort.
How Long Do Boilers Last?
The average boiler can provide dependable service for 15 to 25 years, depending on its quality, water conditions, and how well it’s maintained. Routine inspections and servicing are key to getting the most years out of your system.
Will My Existing Pipes Work with a New Boiler?
In many cases, your current plumbing may be suitable for your new boiler, provided it’s in good condition. If your pipes are free from leaks, well insulated, and allow steady water flow, they can often be reused. However, if corrosion, leaks, or pressure problems are present, replacing or upgrading them can boost efficiency and help protect your new boiler.
How Much Does Boiler Installation Cost?
Several elements influence the price of a boiler installation, including the type of unit, its heating output, the size and layout of your home, and whether upgrades are needed for ventilation or piping. While high-efficiency systems may have a higher upfront cost, they typically offer long-term savings by reducing your energy use.
