"I have used the company several times.  They are up front with an estimate that they stick too.  They arrive when they say they will and even give you a notice by phone when they are a few minutes away.  No problems with their work at all.  Today I called them and they came out.  It was more of a 'boiler issue' to which I was referred to a company specializing in boilers.  I wasn't charged a dime, even with him quick fixing a leaky shut off valve.   Most places would have at least charged me for a minimal service charge just for showing up.  They do business the old fashioned way and they will be my plumbing people from now on."

"We pay yearly but we have this is included with our rental property. They are pretty good on most things. We had a hot water heater replaced and they did an excellent job on that. They are very quick on their response. They dont come out here. It is all done on the internet.  I just like the idea that one time service charge is so much better than trying to hiring someone to come in. It is more about convenience. It pays for itself."

Water Heaters FAQs, answered by experts

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.

A tankless water heater can last up to 20 years, which is nearly double the lifespan of a conventional tank heater. However, their longevity is highly dependent on several factors. With proper installation and regular maintenance, such as descaling to prevent mineral buildup from hard water, you can expect a lifespan of 15 to 20 years. Without proper care, a tankless unit may begin to fail in as little as 12 years. Other factors that affect its lifespan include household usage and the quality of the local water supply. While they have a higher upfront cost, their energy savings, smaller size, and longer life make them a worthwhile investment for many homeowners.

An average-sized empty water heater weighs around 150 pounds. Tankless water heaters are much lighter, weighing between 10 and 50 pounds. The smaller size and added convenience come at a price, though—tankless water heaters average about twice the price of their traditional counterparts.

No. Expansion tanks must be installed on the supply side (where heated water flows out) of the boiler. There’s also a list of other requirements for most boilers, including being above the pressure relief valves, being on the inner side of any circulator, and more. Your installation manual should have more information on expansion tank installation requirements and what sort of tank the system is made for.

Any item that can hold on to moisture and encourage mold growth should be discarded and replaced following water damage. Upholstered items, such as armchairs and couches, and soft items, such as mattresses, usually must be thrown away once they've taken on a lot of water. Soft furniture is difficult to dry out, creating an inviting environment for mold.

You may also need to replace hardwood furniture following water damage if you're unable to fully dry it out. If you have appliances and electronics that have been fully submerged in water, particularly sewage, you'll need to replace those, too.
