"The service adviser came out and gave us a price. We got three estimates and they were in the middle but were also providing us with more options. The install crew showed up on time and were very polite while on site. They called a few days later to check in and see how we were doing. It was a very simple process. Would use them again in the future,"

"Scheduling the work for a new dryer vent was not only easy and prompt, but the young lady who scheduled was more than helpful. The company offered a coupon on Angie's List which I had not purchased. After I mentioned finding the great reviews on Angie's List, she told me I would save by purchasing the coupon, which we did. Wayne and Robert arrived on time and proceeded to install the new vent after explaining what they would do. They reconnected our dryer to the new vents, replaced it and tried it out. Finally, they replaced a door that had been taken down by the new washer and dryer installers when they were done. This is one of the most professional and dependable companies we have had in our home, and we will use them again if needed for duct work."

"After talking with several plumbers, I decided to use Southeast Plumbing and Gas. Brian answered all of my questions and quoted me a very competitive price. Brian installed a new dishwasher, put in a new tankless water heater (plus ran new electrical for the unit) and some other smaller fixes. He was professional, courteous, and did the work for what he quoted. He also tackled some additional plumbing issues that cropped up while he was doing everything else. He was at our house for over 12 hrs fixing everything and making sure everything was working properly before he left. I would definitely recommend SE Plumbing and Gas and would use them again."

"The contractor performed an outstanding installation. The first visit, he assessed the work to perform, then walk me through the process he would perform. He offered various units to accommodate my requirement before I decided on the best option. On the day of the installation, he arrived on time, took the necessary safety precautions, did the installation and then walk me through the process of what he performed and showed me the operations. His quality of work (A+) and the cost (A+) met our expectations."

Install Boiler FAQs, answered by experts

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.

Many utility companies and government programs offer rebates or incentives for the installation of high-efficiency propane boilers. These can offset upfront costs and improve your return on investment. Check with your local utility or installer for current offers. Incentives vary by state and provider, so exploring regional programs can help maximize your savings.

Yes. In many cases, switching from an old furnace to a high-efficiency boiler can help you save money over time. You can also save money by switching from an electric boiler to a gas boiler, which costs much less compared to the energy bills an electric boil can create. Boilers are often (but not always) more efficient than furnaces, too. Then there are discounts, rebates, and incentives that can help you save on the initial costs.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.
