"David and his team are always on time and deliver exceptional quality work. I did 3 big projects with them over last 2 years and will hire them again if needed. His estimates are very accurate and he will tell you when the project should be done. I recently had to call them right before 4th of July due to my boiler not firing. He came next day and quickly found the issue (the back draft sensor triggered and had to be reset). He explained why this usually happens and how to reset it myself. He and his crew had a project in my area and due to that didn't charge for this visit. This is the honest plumber I was looking for!"

"Mo was a very able, responsive and professional technician who installed our furnace in one day and our new boiler two days later. He patiently answered my many questions, walked me through why we needed two new units (instead of repairing our old ones) and worked well and efficiently. It was painful to have to pay that much money at once for a furnace and a boiler, but Mo made it as positive an experience as it could have been. I am grateful to him and his assistant for their work and professionalism."

"It was a superb experience. From the visit by Bruce the sales representative to the installation day to the follow-up from Petro, every single person we interacted with was helpful and professional. When Bruce arrived to do the assessment, we spent time going over the heating needs in the house. After a thorough inspection and measurement of the house, we sat down. He showed me a few options, all of which were going to provide good service. I ordered a unit at the end of that meeting. The installation day was just terrific- the entire work crew that showed up were everything I would hope to find: Upbeat, informative, hard-working, focused. The job was finished before end of day as promised. The heater room is now immaculate, with new piping and a new heater. It was like watching a pit crew at a NASCAR race. Everyone had their tasks, they moved carefully but quickly. The materials were all laid out in order, etc. Just a totally professional approach to their work. The crew boss answered any questions I had. The follow-up for a normal inspection of the furnace chimney was scheduled the day after the installation. I’ve gotten calls to insure we are satisfied with the work. Satisfied barely covers it- I am pleased to write this kind of review. Without hesitation I will recommend Petro to friends and family throughout the Philly area. Peter A. Elkins Park"

"I used them to install a gas line and hook up a new gas stove. Vince was through and very knowledgeable of what needed to be done. The price was exactly what he quoted, the pipe install was very neat and clean and he connected the stove, tested to make sure everything was working as well as check all the existing gas appliances to make sure they were working after turning the gas back on. I will be using Vince going forward for all of my plumbing needs!"

"Received call from Melissa, who was friendly and professional. Plumber George arrived promptly. He was able to quickly diagnose and resolve a frozen pipe on my heater system, preventing a potential rupture that would have been aggravating and expensive! Very friendly and professional service from start to finish."

"Zach from PipeWorks came today to install a new kitchen faucet and do an annual clean/diagnostic of the basement boiler. In both cases, he discovered and patiently explained upgrades and replacements, which he performed expertly. He also answered all of my questions with care â including the dumb ones â and explained the charges clearly. Zach didnâ t try to upsell me anything unnecessary â he did what he needed to do and didnâ t do what he didnâ t need to do. Finally, heâ s a very nice and polite guy, which made the event comfortable and trustworthy. Iâ m thrilled with my upgraded faucet, which works perfectly, and glad to have the boiler in tip-top shape for the season. I happily recommend Zach and PipeWorks to be your in-home experts for fixes and recommendations."

Install Boiler FAQs, answered by experts

A common HVAC rule is that for every 500 to 600 square feet of living space, you need 1 ton of heating or cooling capacity. Now that you know this common rule, you also need to know that it isn’t very accurate, and a dedicated pro wouldn’t use it for your home. If you talk to a pro who won’t or can’t perform a proper Manual J calculation, consider hiring someone more thorough.

The best way to compare HVAC quotes is getting a few detailed quotes from local companies with good reputations. Then, go over the quotes line by line. Protect yourself by insisting on in-person estimates that include equipment manufacturer names, model numbers, SEER ratings, amounts and numbers of materials, details of warranties on equipment and labor, and other specifics. 

Knowing the exact equipment and materials is the only way that you can fairly compare quotes. Quotes that are much lower than others can be a sign that the company isn’t providing the best quality service or materials.

No, boilers and water heaters are not interchangeable because they serve different primary functions. Boilers are used for central heating systems, providing hot water or steam to heat your home. In contrast, a water heater's purpose is to supply hot water for daily household use, such as for faucets and showers. A water heater alone cannot supply the warm water or steam needed for a central heating system.

While they are not interchangeable, it is common to have both a boiler and a water heater. In fact, a conventional boiler often works best when a water heater system is already in place. The two systems can be combined to provide both heating and hot water, either by pairing a boiler with an indirect water heater or by installing a premade combination boiler-water heater unit. For home heating, some homeowners may also opt for a furnace instead of a boiler.

The cost of heating oil fluctuates rapidly based on supply and demand, but the average price is between $4.00 and $4.50 per gallon, which means filling a standard 275-gallon tank would cost between $1,100 and $1,240. Much like automotive gasoline, the price of home heating oil changes constantly, so the only way to get an accurate and current price per gallon is to contact a heating oil delivery company. Some companies also offer contracts with a set price that should be an average cost over the contract term.

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.
