"Everything went great. The old hot water heater was removed and then the new hot water heater was installed where I requested it to be with all of the plumbing done in a neat professional manner. It was a pleasure working with Bamford plumbing and I have been very happy with the work they have done. I would highly recommend them to anyone.

"After several repairs over a couple of years we decided to replace our 14 year old central AC system with a new heat pump system. We got quotes from 3 companies, and decided to go with B.A.R. Appliances AC LLC based on past experience, extended warranty, and very competitive costs. The entire installation was efficient and professional. I found Henry and his staff a pleasure to deal with. They left me with a nice clean system and I would highly recommend B.A.R. Appliances AC LLC for any HVAC work. It's nice to have quality work done in this day and age!"

"Ivan, from It's Phenomenal Air Heating and Cooling, was great. He was very professional and patient when answering our questions prior to accepting his quote to do the work. And additional bonus is that he recommended the Goodman A/C and heating systems, which get very good reviews and are not overly expensive. On the day of installation, he was very thorough and made sure the work was done properly. He also followed up with emails and made an additional visit to check the humidity levels in the house. We will definitely hire him and It's Phenomenal again for any other HVAC work and we recommend him to anyone else needing such work done."

Install Boiler FAQs, answered by experts

All modern boilers are condensing boilers because they’re the most efficient type. Instead of extra heat leaving through the flue, these boilers trap the heat and use it to heat the house. Whether you choose a combi boiler, system boiler, or regular boiler, you can opt to get a condensing system. If you have an old boiler that’s not a condensing boiler, it’s a good idea to get an upgrade.

If you go to turn it counterclockwise and it won’t turn anymore, it’s open. Like most other valves, you should be able to turn a radiator valve counterclockwise (to the left) to open it and clockwise (right) to close it. To close a radiator valve, turn it clockwise until you meet some resistance and can’t turn anymore, but do so carefully to avoid breaking the valve.

An expansion tank must always be installed on the supply side, which is the side where the boiler sends water out to heat the systems. That placement allows the water to push against the air and condense properly as it is heated, then circulated through the system. Professional installers can recommend the best place on the supply side for an expansion tank.

Warmed or cooled air can escape your home through drafty windows and doors. If you notice any gaps, be sure to caulk and seal them. You can also hire a local pro for an energy audit to get a list of energy-saving recommendations. 

Finally, check your insulation. It can settle in over time and become less effective. The Environmental Protection Agency (EPA) estimates that you can save an average of 15% on heating and cooling costs (or 11% of total energy costs) by sealing leaks and making sure attics, crawl spaces, and basements have a nice layer of insulation.

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.
