"Very please with the install. Vin was very professional and applied due diligence to the project. His oversight and instruction provided the reinsurance that needed. I requested four heating and AC vendors to provide proposals. Tyler was most responsive to my questions and offered me alternatives along with helpful suggestions. My next project is my boiler. I will be turning them in the future."

"While out of town, got word basement might be flooded. Called Schede to check boiler and hot water heater.. They went out the same day. Discovered sump pump wasn't working so replaced it. Cost pump and labor $800. Over the years they have responded to many problems, leaking faucets and stuck drains. Biggest project replace boiler for steam heat. Took 5 guys to wrestle boiler down a narrow basement stairway. Patient with a few family disagreements. Nothing to do with them. Installation successful. They've always been prompt courteous and non judgemental when encountering crazy working conditions. Think they are great. Boiler and hot water heater were fine. They installed both."

Install Boiler questions, answered by experts

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.

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.

A furnace is a big unit where gas, heating oil, or electricity heats the air. The warmed air is then pushed back out through ducts and vents. 

A boiler uses electricity, heating oil, or gas to heat water that is pushed into the room through a radiator. This is one of the oldest and most effective ways to heat a house, but radiators can also be unsightly and leave hot and cold spots in the room.

Heat pumps use a refrigerant to move heat from outside into the house and return it to the room through ducts and vents.

The average lifespan of a boiler is typically between 15 and 20 years, though some may last for as little as 10 years while others can reach 30. A boiler's longevity is influenced by several factors, including the quality of the unit, proper installation, and consistent professional maintenance.

The material also plays a significant role. Older boilers made from durable cast iron can last for over 20 years, with some functioning for up to 50 years. However, it's important to consider their lower efficiency, which can lead to higher utility bills. Modern boilers, often made from steel alloys, are designed to withstand high pressure and temperatures and have an average lifespan of about 20 years.

To maximize your boiler's lifespan, ensure it is installed correctly, have it professionally maintained each year, and address any necessary repairs immediately.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.
