"Rich told us it would be months before windows were installed due to supply shortages. Sure enough it took a few months but was it worth the wait. The new windows block out noise and the summer heat. I don't even have blinds on them anymore since I enjoy looking outside. They redid the stucco trim around them. My house looks brand new. Worth the money I spent. Better news, they are lifetime guaranteed so I won't need to do this again. Thanks Superior!"

Install Boiler questions, answered by experts

If you're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.

You save money on heating oil in a few ways:

  • Make sure your home is well insulated and sealed against drafts and heat leakage.

  • Use a thermostat that’s working properly and calibrated accurately.

  • Increase energy efficiency by insulating your basement and attic.

  • Turn down your thermostat a few degrees.

  • Program your thermostat to lower the heat when you’re not home.

  • Order heating oil during the off-season when prices are likely to be lower.

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.

Heat pumps offer much more efficiency than a boiler, relying only on electricity to provide 3 to 4 times the amount of heat you can get from a boiler, which runs on fossil fuels. You can save money over time as it costs less to maintain and operate a heat pump, though you will pay a higher price upfront to install it compared to a boiler.

Modern boilers average around 20 years of use before failing, with some hitting 25 to 30 years. Older boilers, however, can last up to 50 years because they are often made from ultra-durable cast iron. Newer models are made from steel alloy and related components, which are great for withstanding high pressure levels and hot temperatures but offer a slightly lower life span.
