"Williams & Associates installed a Buderus oil-fired boiler and stainless-steel chimney liner. Bruce's design was a significant upgrade over my 35-year-old boiler system. He clearly explained the process and installation, and he was receptive to my questions. Bruce is knowledgeable, straightforward, and responsive. The price was very fair, considering the quality of the work and other estimates I had gotten. I would not hesitate to recommend Williams & Associates."

"Very well. I had an appointment for approximately 8 AM. They were a bit late, but had called to let me know, and it wasn't a problem for me. They spent well over an hour on the job. They took a ton of lint out of the vent pipes and the dryer itself. I'm pretty sure that whoever it was I had in last time did not open up the dryer to clean it. They also installed a "bird cage" around the vent opening on the side of the house to prevent critters from getting in. (I don't think I have had problems with birds getting in, but why take the chance?) They were very thorough. The job cost more than the initial estimate, but this was because my vent pipe was longer than I had realized. It was reasonable."

"I received a phone call almost immediately after requesting service for my boiler. I was scheduled for the very next day, and the work that was done was done quite well. Greg, the service tech who came out, explained to me what he was doing as he was cleaning my boiler. I highly recommend using this company!"

"Rd.I had to pay an extra $15.00 because I had an extra air duct or intake vent. He discussed how often the ducts should be cleaned and offered another service that would help disinfect and keep dust mights down. The extra service also extended the length of time before I would need to have the vents cleaned again. I chose the extra service and will not have to have it done again until 8-10 years from now. My nephew who is 45 was not happy I was having the ducts cleaned but he was pleased with their work in the end. I had this done in my last house twice so I am not new to this. I was pleased with their work. They started immediately and finished about an hour and fifteen minutes later. I have house that is almost 2,000 sq. feet. The $230.00 includes the $89.00 I paid when I ordered it through Angie's List.

Install Boiler FAQs, answered by experts

Many utility companies and government programs offer rebates or incentives for the installation of high-efficiency propane boilers. These can offset upfront costs and improve your return on investment. Check with your local utility or installer for current offers. Incentives vary by state and provider, so exploring regional programs can help maximize your savings.

Safety concerns with propane boilers include proper venting to prevent carbon monoxide buildup, secure gas line connections, and regular inspection of safety controls. Professional boiler installation and annual maintenance are essential to minimize risks. Having a carbon monoxide detector installed in your home is essential for early detection of any leaks or ventilation issues.

You can save money on heating oil through a combination of improving home efficiency and smart purchasing strategies.

Home Efficiency and Usage:

  • Improve Insulation: Ensure your home, especially the basement and attic, is well-insulated and sealed against drafts to prevent heat leakage.

  • Manage Your Thermostat: Use a properly calibrated and programmable thermostat. Lower the temperature by a few degrees, particularly when you are away from home or asleep.

Purchasing Strategies:

  • Buy in the Off-Season: Order heating oil during the summer months when prices are generally at their lowest. This strategy is most effective if you have a large primary tank or a separate storage tank to accommodate bulk deliveries.

  • Consider a Delivery Contract: Some companies offer contracts with a set price for the term. This can lead to savings if market prices for oil increase, but you might pay more if prices drop.

Boilers are equipped with multiple safety features to ensure safe operation. These include pressure relief valves to prevent overpressure, temperature high-limit switches to avoid overheating, and flame failure safety devices in gas boilers to cut off the gas supply if the flame goes out unexpectedly. Low water cutoffs prevent operation with insufficient water levels, and pressure gauges help monitor pressure levels. Ventilation and flue systems prevent the buildup of harmful gasses. Boilers often feature error code systems for automatic shutdown during malfunctions and gas leak detection for safety. Regular maintenance is crucial to ensure these safety features function correctly.

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.
