"Only rating 1 because it doesn't go lower. Had a new unit installed end of Sept 24. First time power goes out on 11/5, no electricity. When tri state sells you a product, they pitch their amazing customer service with all these guarnatees of knowing when your unit is out before you know and having someone there within 24 hours etc. Well, the first call we make we are told it will be the end of Nov to get someone out to look at it. 3 weeks. Nobody shows up. Then we get a call that says "your appointment on Dec 12 has been canceled and the earliest we can get to you is Jan 16th. This is 2.5 months wait to get service to fix a nearly $20k unit, that is upcharged because of the excellent service. You can't get anyone to answer your call. you wait on hold for 20 minutes, then have to leave a voicemail in which you will not get called back. Based on my experience, find someone else and pay less. Even if the service is bad, which it can't be worse than this, you save money! @kohler"

Install Boiler questions, answered by experts

The absence of heating or hot water, unusual noises like banging or gurgling, and visible water leakage are key signs. Abnormal boiler pressure, flame irregularities (for gas boilers), or pilot light issues may also signal trouble. Frequent cycling, soot or staining, and unusual odors, particularly gas-like smells, should not be ignored. Modern boilers often display error codes or lockout mode upon detecting issues. Uneven heating across radiators and rising energy bills without increased usage can further point to problems. Prompt attention to these signs is essential to prevent further damage and ensure safety.

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.

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.

It can take anywhere from four hours to three days to replace a boiler with a new one. How long your particular boiler installation takes will depend on whether you need a gas line installed and if you’re switching to a new boiler system. 

Replacing a combination boiler or standard boiler with the same system should only take four to six hours. Meanwhile, switching from a conventional boiler system to a combination boiler system could take a few days.

Boilers provide even heating, energy efficiency, and a quiet operation compared to forced air systems.
