"Brian at Clear All was recommended by a friend and they lived up to the recommendation and beyond. Helped trouble shoot a broken boiler for my in-laws and once he saw it he highly recommended replacing the boiler. I knew this was not an up-sell as the boiler was in very rough shape. While the new boiler was obviously more expensive then the repair, the price quoted for the boiler, burner, install, and removal of the old system was very fair - too good to pass up and risk throwing good money at bad with a repair on a 20+ year old boiler. Contacted them on a Monday, Brian showed up on that Wednesday to assess the situation and the new boiler was installed and running by 5 pm Thursday. He kept me in the loop through the whole process even though it was my in-laws boiler install. He also took the time to evaluate the size of the house and recommended a much smaller boiler - the existing one was way oversized and therefore over-using heating oil."

"The service technician Victor arrived on time and politely introduced himself. Prior to commencing work he inspected the work area (installation and clearances etc). He explained the house heating would be off as he cleaned filters etc. After cleaning/adjustment/testing was conducted, he went over the test results printout with me. All good and nothing required further work."

"Wonderful service from Adam! My water heater was struggling to keep up with my wife?s long showers - which by the way she heats them up hot as hell! ? Besides the point, Adam recommended sizing up the water heater in order to keep up with the demands of some crazy hot water. Incredibly fast installation process and Adam was really friendly. I would definitely recommend him to all my friends who are looking for a plumber. You should certainly give him a call!"

"Project: Replace Boiler and Hot Water Heater It is refreshing to find a contractor during theses times that takes the time to explain all the options you have available and answerer all of the questions you have. Most contractors just give you a price and that is it. Jarod really does go above and beyond and gives you that personal touch and honesty. We did receive other quotes and went with Jarod not because of price, but because of the service he provided during the quote process and the time he took to answer all of my questions. We choose to go with Natural Gas Boiler and a Tankless hot water heater. He showed up on time and kept us informed throughout the process of what he was doing. Did a great job on installation very clean. Will defiantly be using Jarod Moulton Mechanical Services for future service needs. Great Service means a lot and Jarod provides that."

"Sunrise Heating and Cooling did an excellent job installing my new Rinnai tankless water heater/boiler. From start to finish, the experience was smooth and professional. The crew was knowledgeable, punctual, and took the time to explain the system and answer all of my questions. The installation was clean, efficient, and clearly done with attention to detail. Everything works perfectly, and I couldn?t be happier with the upgrade. It?s clear they take pride in their work. If you?re looking for reliable, honest, and high-quality service, I highly recommend Sunrise Heating and Cooling."

Install Boiler questions, 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.

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.

Deciding whether or not to replace radiators with a different heating system depends on your personal preferences. Radiators can take longer to heat up than a central heating system, and they take up floor space. However, they can be very efficient at heating, and they keep rooms at a more comfortable humidity level in the winter than forced-air systems.

Since your boiler keeps you warm and provides hot water to your home, you’re likely to notice issues with heating in your living space right away. The most obvious sign that your boiler is breaking is not getting any heat or hot water. You might also hear some odd sounds coming from your boiler during operation, the flame in your gas boiler is not blue, the pressure is inconsistent, or your boiler is using more energy than it should. If you notice any of these signs, be sure to call a pro right away.
