"We had an older Heatmaker combination unit boiler that was 32 years old that needed to be replaced. We started out with several estimates and first decided what could be used in our space constrained garage. We decided on a Navien combination unit and focused a obtained a couple more estimates. Dawson in fact was one of the last estimates we obtained. While Dave from Dawson had the benefit of us being well along the learning curve, he was able to answer all of our questions about the new unit and how best to solve the condensate dilemma. He even was spot on with regards to treating our well water to minimize scale buildup in our new boiler. We knew we had reached that point where we felt we had found the best installer in Dave. Dave verified his condensate solution with the local township inspector and we scheduled the install date in two weeks. Carlos and Pablo showed up on time and dismantled the old unit and piping and did a first rate and well thought out installation job. Carlos had extensive experience installing these Navien units and it really showed. They managed to work in a tight space that PSE&G’s installers would not have with relocating a well tank. After all the plumbing was done, Ricky did the electrical work and adjusted some final dip switch settings before firing up the new boiler. Dave and his crew really are top notch. His front office staff (Wanda and Ondrea) made the PSE&G interest free financing and permitting approval process seemless. We are looking forward to the operation and efficiency of our new high efficiency boiler for years to come. If you are installing a Navien high efficiency combo unit, we highly recommend using Dawson Mechanical!"

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"The technicians performed routine maintenance and repair of two boilers their company installed two years ago. They did a thorough job of flushing the water heating lines, testing the system, and re-installing a low-water shut off valve that had failed last year. I have used this plumbing company for years and will continue to do so, highly recommended to people in the Northeast New Jersey area."

"Braido is a nice family run company.  I had the original 25 year old furnace and AC. I has the last house on the block to replace them.  Needed to get it done before winter.  They showed up the day I called for an estimate, took measurements, checked old system and discussed in detail my options for a replacement system.   No pressure to sell me the best as we will down size in a few years. A few days later quotes for two systems arrived. I was able to scheduled an installation that fit my schedule.  It was your typical one day job.  Everything went smoothly with the installation, and the old hardware was taken away.  I like this company and recommend them, I give them and A.

"From the estimate to the final installation you won’t find a more professional company. They installed a new carrier furnace and air conditioner and did an excellent job. I highly recommend them for any of your HVAC needs."

"Keith and his crew are extremely professional and knowledgeable, and did an outstanding job installing a heat pump and brand new ductwork into a difficult old house. They notified me of arrival times, were prompt, neat, and did the work efficiently and quickly. I highly recommend this company and will be using them again for future projects!"

"I needed to install a water powered sump pump. Tom gave an estimate and actually charged me less because the digging didn't take him as much effort as he had estimated. He made sure I got the equipment in order and he returned an earlier delivery since he wasnt satisfied with its float assembly. The job was completed professionally and on time. On top of that he is a very nice person to deal with and fixed a couple of minor issues with my other faucets at no extra cost. Well recommended an I will call him again if I need any plumbing work done."

"Both Tara and Robert have been very professional and courteous from the time of the first call till the end. Robert gave extra attention to my specific water heater needs and came back a second time to install and remove a recirculation pump. Also fixed a minor leak on a Sunday. I have recommended to have them add to my HOA preferred vendor list."

Install Boiler FAQs, answered by experts

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.

A home radiator works by using radiation and convection to transfer heat throughout your home. Electric radiators use metal to conduct heat and warm the air, which then rises to warm the room. Steam and hot water radiators work with a boiler and piping system to pump thermal energy throughout the home. Hot water radiators use a boiler to heat the water before circulating it to the radiator, while steam heating radiator systems convert the heated water to steam before circulating it out. When the water or steam cools, it travels back to the boiler to be heated again.

Boiler installations and replacements cost between $3,600 to $8,400. Expect to pay around $5,900 on average for a new boiler, including installation. Adding new radiators or heaters to the boiler may include separate costs if you are also upgrading those components, so the final price may be higher. To decrease costs, you can look for local energy rebates for using a boiler and wait until installers are offering discounts for a first-time installation.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.
