"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

Although baseboard heating is expensive to operate, hydronic style heaters usually aren’t as costly as other models because they maintain temperature longer than standard electric baseboard heaters. Since the liquid retains the heat longer, it prevents the thermostat from turning on and off as often, which makes it more energy efficient.

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

Costs depend on system size, efficiency rating, and additional features like zoning or smart controls.

Yes, you can build a sunroom addition to your home despite living in a cold climate. Make sure to use high-quality insulation and windows and to supplement with sufficient heating from your HVAC system. The windows in the sunroom allow enough natural light into the room to help heat it most times without having to use the furnace. Even a small electric fireplace can heat the sunroom well enough.

Radiators are a popular home heating choice in older homes, but they are becoming less common in new-construction homes. According to a 2022 report by Elements Visual Capitalist, only around 1.3% of new single-family homes have radiators and similar heating systems, such as baseboard heating.

While they may not be as popular as they once were, radiators today come with more energy-efficient features that can make them practical for modern homeowners.
