"Father son team installed a high efficiency gas boiler and water heater. They did an excellent job replacing the old boiler and were fairly priced compared to the other estimates I received. The new system is working well and looks great. I would use them again."

"I'm submitting this review about 2yrs late. The Guys at Green energy are great! While they had a hard time transforming my house's old oil system to gas, Jonathan never stopped taking my calls (don't take that from granted, many contractors don't care once they have your money). They worked on it for several weeks--tweaking it until it finally took. 2 winters later, it works perfectly. I'm sure other contractors could've had the same problem and not been as responsive and committed as them. I'll definitely be hiring them to convert to tank-less water heating and to install AC!"

Install Boiler FAQs, answered by experts

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

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.

Most propane boilers last 15 to 20 years with regular maintenance and proper care. The lifespan depends on the quality of the unit, proper installation, and the level of maintenance. Investing in annual service can maximize longevity and efficiency. Routine inspections and timely repairs prevent early breakdown, ensuring your boiler heats your home for years to come.

The primary differences between a heat pump and a boiler are their function and how they produce heat. A heat pump is a versatile system that provides both heating and cooling by moving ambient air and altering its temperature. In contrast, a boiler is solely a heating system, often working with a furnace or AC unit as part of a larger HVAC system. In terms of heat production, a heat pump generates heat more slowly and at a lower temperature, requiring a large convector for distribution. A boiler, however, produces a large amount of high-temperature heat that it emits through smaller radiators.

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.
