"I needed quick service on a 45 year old hot water boiler in a 1938 house I recently purchased.  While I could get the pilot light lit, nothing I did could get the boiler to fire (water was circulating).
On Wednesday I contacted Pelletier Mechanical as Gary (the owner) had been out giving me estimates on the various repairs and modifications I wanted to make.  While Gary was out of the office training (again), Laura his admin arranged for Bill to come out on Friday.  She provided an estimated cost (right on) and a 2 hour window.
Bill showed up on time and after a brief discussion get right to work.  Bill spent about 15 mins. systematically determining why the flame would not light.  He discovered that there the gas was not making it to the main control valve.  He reset the safety shut off valve and the problem was solved.  He then checked all the radiators to make sure that hot water was making it through out the house.  After we determined that the upstairs radiators were not getting hot, Bill checked the water pressure and determined that the pressure was insufficient to fill the upstairs radiators in "real  time".  He suggested that the culprit was the 45 year old water valve and pressure release valve which being cast iron tend to corrode and clog in time.  He proposed a replacement solution and priced it out, and offered to pick up the parts and replace the valves that afternoon.  I decided to wait a few weeks so I could consider replacing the entire boiler.
While we were waiting on the boiler to come up to heat, Bill and I walked through the basement looking at the existing plumbing, tracing the water flow path and discussing the possibility of replacing the hot water tank with a tankless unit. (The hot water run is about 60-65 feet from HW tank to kitchen, bathrooms, etc.)  Bill, like Gary, is knowledgeable and informative.
I will have Pelletier Mechanical  back to do more work on the house."

Install Boiler FAQs, answered by experts

The cost-efficiency of baseboard heaters depends on the type and how you use them. Generally, standard electric baseboard heaters can be expensive to run because they use electric resistance heating, which is less energy-efficient than systems like forced-air or heat pumps. However, hydronic and gas versions are typically much cheaper to operate. Hydronic models are more energy-efficient because they heat a liquid that retains warmth longer, preventing the thermostat from turning on and off as often. The overall running cost is also influenced by local electricity rates, your home's insulation, and your usage habits. To increase efficiency, you can use baseboard heaters for zoning, meaning you only heat the specific rooms you are using.

It takes about five to 10 minutes for heat to reach a radiator, then about one hour until the radiator fully heats up a room. The exact duration depends on the size of the room and how far away the radiator is from the boiler heating system. Heating up an entire house could take up to two hours.

If you're often struggling with radiator issues like chilly spots, leaks, or annoying noises, those are common indications that your radiator may need to be replaced. Corrosion, uneven heating, and persistent hissing sounds are common issues as well. When repairs become a regular chore and your home’s energy bills start to rise, a new radiator will bring the comfort and savings you need.

Overall, heating your home with an oil furnace tends to be less expensive than heating your home with an electric heating system. Oil heating systems stay warm for longer periods of time without drawing a constant electrical current to maintain a temperature. Plus, heating oil systems typically have a longer lifespan and lower price tag than their electrical counterparts, resulting in short- and long-term savings.

In most cases, repairing a radiator is more affordable than replacing it. A typical repair may cost between $100 and $200, while a replacement can average $1,500, with a range of $250 to $2,500 depending on the unit type. Radiator issues are often simple fixes for a professional, such as a blown fuse, malfunctioning thermostat, or a loose valve, and can take less than an hour. However, if the long-term costs of fixing the radiator are higher than replacement, it's better to get a new model. It is recommended to consult a heating expert to diagnose the problem and determine the best solution for your situation.
