"Williams & Associates replaced an ancient, very large old boiler in my very large house. Bruce calculated the necessary size and found a suitable boiler. He and his crew thoroughly cleared the radiators and lines before removing the old boiler and installing the new one. They checked all the radiators and added new valves as needed during a lengthy checkout. It took several days to do all the work. Throughout, Bruce explained what they were doing and why as well as recommending changes/additions to the original proposal. They were even cheerful about removing the original "Mary Jane" from the basement. I would definitely recommend them to anyone using steam heat. Great job!"

"I gave Petro an overall "C" rating because that's halfway between their good score for service and their bad score for prices. I was a Petro customer for approximately 22 years, but I switched to a different company this summer because I could no longer afford Petro's prices. If it weren't for their high prices, I would still be a customer of theirs. IMO, with respect to prices of home heating oil, Petro charges one of the highest per-gallon prices in northern RI. During the past few years I've compared oil prices with friends who bought their oil from other companies, and the prices I paid were always between 60 cents and one dollar higher per gallon than what my friends paid. As a senior on a fixed income, paying a dollar more per gallon is no longer an option for me. I was on automatic delivery for heating oil, and up until a few years ago that was great. However, at least once during each of the past two winters, I had to call for a delivery when the oil level in my tank was almost at the bottom. With respect to having one's boiler serviced by Petro, the service was good, and their technicians were always professional. If you have a service contract, you have the peace of mind knowing you can call them 24/7, no questions asked. But you will pay for the privilege. Overall, my opinion is, if you don't mind paying Petro's prices, you will be very happy using Petro for your home heating needs."

"Jim Farrell and North Alabama Technical Services rebuilt my computer and provided me with everything I expected and so much more.  He provided the various options in equipment, including specs and pricing, answered all our questions and helped us make the best decision for our purchases.  The computer was completed in a few days, far less than expected, the installation included clear directions for use.  The package also included a good warranty for the equipment.  I was extremely pleased with his service and would not hesitate to recommend his company to anyone with computer service needs."

"Vista Home Improvement was contracted to resurface my decking surface and to install new railings. The company also did
some siding work as well. Overall, I was very pleased with the work and the quality of work.  Brian is very personable and was always willing to answer any and all questions I had.  From the beginning of the job to the very end Brian was extremely helpful and whether it was through phone calls, emails or in-person conversations Brian always answered my questions and concerns and
ensured all my questions were answered. Additionally, the quality of the work was outstanding. I am very much a perfectionist and really strive to have contractors perform work to perfection.  With Vista Home Improvement even my very small concerns were addressed by the company even though for 99%of the population the very small concerns would not have been noticeable.  The employees of Vista Home Improvements were top notch professionals (I mean everyone from Brian to Kim in the office to the
on site employees!!) and they also answered any questions I had during the project.  They were all very professional and did not take short cuts even when the work was going to be covered up.  The employees, including Brian, were always very punctual and very responsive! I strongly recommend this company to anyone looking to have home improvement work performed and I would definitely use this Vista Home Improvement in the future for home improvement work!! In the end the desk and siding work came out fantastic! even the railing on the desk was perfectly installed!  Brian and his crew measured the railing sections to perfection and they fit perfectly!  I have used a good number of contractors in the past to perform a variety of home improvement projects so I can honestly say through quite a bit of experience using home improvement contractors that Vista Home Improvement was the best of all of them!! To Brian, Kim and everyone at Vista Home Improvement please keep up the Great Work!!!

Install Boiler FAQs, answered by experts

Professionals can recommend efficient layouts or appliances and ensuring regulatory compliance.

Unless they are connected to the same system, boilers and water heaters will both need their own expansion tanks. The only case they wouldn’t have separate expansion tanks is if the boiler is pulling double duty and managing a heating system while also supplying hot water for a home. In which case, you may not need a hot water heater.

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.

On average, you’ll need about two gallons of oil per day to heat your house when it’s 50 degrees Fahrenheit outside. Most oil tank capacity is about 275 gallons, and heating your house with two gallons of oil per day will last about four and a half months. This consumption will vary depending on the climate and average temperature in your location. For example, if the winters are longer and colder where you live, you’ll probably need to refill your oil tank at least once to get through the winter.

You can use a boiler and a furnace, although it’s not common to use both for whole-house heating. For example, your furnace may take care of HVAC heating through your vents, while a boiler powers your floor-based radiant heating in the bathrooms. Mixing and matching like this gives homeowners a variety of heating possibilities.
