"Pipeline Plumbing Oahu L.L.C. is hands down the best choice when it comes to replacing a water heater in Oahu. Their team was prompt, professional, and incredibly knowledgeable.

With a locally owned and operated company, you can expect friendly, personalized service. All Phases Green Services has been in business for over 20 years and offers great craftsmanship in woodworking, cabinetry, counter-tops and installations. We also specialize in tile installation and renovations.

"I would not recommend this contractor to anyone. I hired All Phases Green for a major kitchen renovation. They had done several projects for us before with good results and had been our go-to company for both small and large jobs. The kitchen started off well, and the company was responsive when design changes or unexpected issues came up. However, I noticed the owner’s helper was not meeting the standard I had come to expect from the owner—paint runs, debris in the finish, and sloppy mistakes that stood out even to me as a homeowner. I raised these concerns, expecting them to be addressed, especially since in the past, he was quick to fix any issue. While one of my concerns turned out to be a natural wood issue, instead of explaining that professionally, the owner replied with a condescending text. Shortly after, rather than taking accountability or offering solutions, he abruptly quit the job with another passive-aggressive text message, leaving a large portion of the renovation incomplete. No effort to resolve the situation—just gone. Abandoning a project because a client points out legitimate concerns is incredibly unprofessional. I am absolutely shocked he responded how he did after having worked with him for so long. If a contractor can’t handle feedback or stand behind their team’s work, they shouldn’t be in this business where client feedback should be welcomed. I trusted him, and it became clear what kind of person and business owner he is. I would not recommend this contractor to anyone."

Install Boiler questions, answered by experts

Most home boilers will need an expansion tank. That’s because these boilers are closed-loop systems, where the water is trapped. An expansion tank is needed when the boiler heats the water and it expands, allowing air to condense in the tank to make room for the water. Other types of boilers don’t use an expansion tank, such as traditional steam boilers, but these aren’t as common. And hot water tanks may be able to use a pressure release valve instead. When in doubt, call in a pro to take a look.

The cost of propane and related services varies depending on tank size and location but generally ranges from $500 to $2,500 for installation and initial fill.

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.

The main difference between an outdoor wood furnace versus an outdoor wood boiler is what each appliance is heating. An outdoor wood furnace burns wood to create heat, which warms the air and moves it through the ducts in your home. An outdoor wood boiler uses the heat from burning wood to warm water, which goes through pipes to radiators in the home.

Costs depend on issue severity, parts needed, and labor rates.
