"The installation went well. The crew arrived on time and completed the job on schedule. Included was a one year guarantee on labor and 5 years on the unit. The price was fair. We will use the company again for future jobs."

"Our boiler gave up last year and Heatwave Plumbing & Heating LLC came in and installed a new one. I know so little about plumbing and heating but Dillon walked me patiently and thoughtfully throughout the entire process so that I could make informed decisions. His pricing is honest and fair. Now I rely on them for all my plumbing needs! They worked very hard and did a wonderful job and I am a happy and grateful customer ."

"Mo is an up and coming Plumber but knows as much as someone whoâ s been in the industry for 30+ years. I had an old boiler that was 30 years old and While other plumbers tried to swindle me into purchasing a new boiler, Mo was â more than happy to take on a challenge.â To my surprise, he took on that challenge at very short notice and completed the work that same day. Some plumbers might claim that they canâ t work on the electrical part of the boiler but Mo can do both. I couldnâ t be happier. Thank you Mo!"

"Billy from Elite Piping Solutions was a pleasure to work with. He is pleasant to speak to, thoroughly professional, explains things completely, and addressed additional items that would have become problems down the road. He brought on other professionals as needed without putting the burden for that on us. We expected the new heating appliances to serve us efficiently for many years to come!"

"This Company is top notch! They quickly responded to my urgent message in regard to no heat in the house and had the service guy arrive to the door right after completing another job. They were very professional and did the repair in no time and price quoted over the phone was exactly what was charged for the service. We will definitely call this Company again for any boiler repairs. Thank you!"

"Matthew, the company owner, was very timely in responding and really had very good knowledge of what was needed. He quoted us a fair price and came very early the next morning to quickly, efficiently and cleanly install a new gas steam boiler. Matthew, and his team were superb and I would not hesitate to utilize their services for a future project."

Install Boiler questions, answered by experts

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

If you have a closed-system boiler that requires an expansion tank, you cannot safely operate it without one, as this risks extensive damage or even explosions. You must find a way to make room for the installation. Options include repositioning the boiler, rerouting the boiler piping to a more open area, or performing minor remodeling to create the necessary space. If you are unsure whether your boiler needs an expansion tank or how to best accommodate one, it's recommended to have a local heating service professional assess the situation. They can confirm the requirement and suggest the most practical solution.

If you’re looking for a way to heat your home that is lower in cost and higher in efficiency, you should run the numbers to see what it would look like to switch to gas or electric heat. The best choice for how to heat your home depends on your location, budget, and energy priorities.

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.

Most experts recommend getting three to five HVAC quotes from licensed, insured, reputable local heating and cooling companies. Getting multiple detailed HVAC quotes (but not too many) lets you compare the equipment, services, and prices of several contractors without being overwhelmed by options. It can also let you see if one contractor’s prices are much higher or lower than the others and give you a chance to ask for clarification. That way, you can weed out any contractors who aren’t providing quality services or materials and find the company that best meets your budget, quality requirements, and long-term goals.
