"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

No, there isn’t always water in radiators. In a one-pipe system, water is constantly circulating from the boiler to the radiators and back. In a two-pipe system, water travels through two separate channels: one that goes to your radiators and one that returns back to the boiler so it can heat up again.

Costs depend on unit size, labor, fuel type, and whether additional piping or venting is needed.

A home radiator lasts anywhere from 15 to 20 years with proper maintenance. If your unit is approaching the 15-year mark, it’s a good idea to inspect your system and consider upgrading the radiator to a new one. Older models are less efficient over time compared to newer, energy-efficient radiators.

Modern boilers average around 20 years of use before failing, with some hitting 25 to 30 years. Older boilers, however, can last up to 50 years because they are often made from ultra-durable cast iron. Newer models are made from steel alloy and related components, which are great for withstanding high pressure levels and hot temperatures but offer a slightly lower life span.

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.
