"Brady from Maine Way Heating & Cooling. The gentleman came when expected, very pleasant and knowledgeable. His quoted price was very reasonable and less expensive then the company we used last year. He did find that we needed another part to complete the job he was not pushy about selling it and stated we could schedule an appointment. After talking with him we asked him to go ahead and fix it. This gentleman is very professional and very upfront with his price ...We will for sure call him again next year for service and with any emergencies we may have. Thank You Brady!!"

"We set the installation date months in advance and Jeff showed up on time and prepared. Finished the job ahead of schedule and at the price he quoted. His work is clean and very organized. Jeff left room for zone expansion with circulators and piping stubbed off with caps installed. His piping is second to none…. I highly recommend his services."

Install Boiler FAQs, answered by experts

If you want to have hot water in your home and part of your plumbing system, you'll need a hot water heater. An alternative may be to heat water as you use it, such as by boiling what you need on the stove. But that's much less efficient and takes considerably longer than hooking up a water heater. Another option is to rely on appliances, such as a dishwasher or washing machine, that heat the water themselves.

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.

Chilled water HVAC systems use water instead of traditional components and refrigerants. They're more common in commercial settings than residential ones but are slowly being adopted by some homebuilders to cool homes. As the name implies, the system keeps the water chilled at 40 degrees and circulates it through water coils. The water absorbs the heat from your home and drains outdoors. Condo apartments are more likely to have chilled water HVAC than single-family homes because this system is designed to cool several rooms or large areas individually.
