"We were switching over from oil to propane heat. It was a pleasant experience from the time we first met Jason who was very knowledgeable and a joy to talk to. The installers were very professional and did a great job. Aire Serve worked seamlessly with Curtis oil and job was completed in 1 day. We are warm happy campers and would definitely recommend Aire Serve and Curtis Oil & Propane."

"We not only contracted Eric Stone to install a new water heater, but to also move and install a new well pressure tank, which was failing, from under our manufactured home, to an inside storage closet location, and then re-pipe our home water supply from the new inside location of the pressure tank to the newly installed water heater. When I first met Eric for an initial bid, I felt very confident in the fact that I had chosen the right plumbing contractor for our project, and his knowledge and expertise plus his likeable demeanor did not let me down. Eric's bid was fair and complete, he and his crew showed up on the agreed date and time, and his crew of two additional plumbing techs, Ethan and Hunter, were very knowledgeable, courteous, and just all around good guys and a delight to have them working my home. The finished product of the installation was exactly what I had envisioned, and the work area was cleaned up on completion. Needless to say I am thrilled to death with Eric's work and would highly recommend his company to anyone contemplating a like project."

Install Boiler questions, answered by experts

Yes, most municipalities require a permit for propane boiler installation to ensure safety and code compliance. Permit fees vary by location and are often included in your installer’s quote, as they’ll handle the permitting process. Ensure that you always check local regulations before starting your project to avoid fines or delays.

Steam boilers require flushing at least every six to 12 months to keep them operating effectively for as long as possible. Depending on your water quality and frequency of use, you might need to do this more frequently. The flushing process helps to remove problematic buildup of sediments. While a boiler contractor near you can perform a thorough annual flush, learning how to drain the system yourself means you can do this monthly if you experience speedy mineral accumulation because of hard water. 

Hydronic and standard electric baseboard heaters differ in how they operate, their cost, and their performance. Standard convection heaters use electric coils to heat the air directly, while hydronic heaters warm a contained liquid like water or oil, which then radiates heat into the room.

In terms of cost and efficiency, hydronic heaters usually have a higher upfront price but are more energy-efficient and cheaper to run over time. This is because the heated liquid retains warmth, allowing the heater to continue providing heat for a while after the thermostat turns it off. In contrast, electric heaters provide heat more quickly but are less efficient.

Ultimately, the better choice depends on your priorities. If you need a room to heat up fast and have a lower initial budget, an electric heater might be suitable. If long-term energy savings are more important and you don't mind a slower heat-up time, a hydronic heater is likely the better option.

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.

Scale from hard water is hard to diagnose until it starts causing problems. If your area has particularly hard water, that’s most likely what your boiler is using. If scale build-up becomes a problem, it starts to cause decreased flow and heating, and eventually, valve failures as valves become blocked. Let boiler professionals know if you’re worried about scale and they can offer advice or implement a solution.
