"Bruce and Bill of Williams and Associates Mechanical Contracting recently removed and replaced my 18 year old oil fired boiler and added an indirect fired water heater. I had been saving for this project for over a year and had been geeking out in my avid research (Thanks Internet!) of products available, reviews and costs, as well as the reputation and reliability of local heating and plumbing contractors. I knew what I wanted, I just needed to stay within my budget and find a contractor I could trust. It is therefore, my pleasure to let others know, on the same web review sites that I referred to, how overwhelming pleased I am to have worked with Bruce Williams and his team. They skillfully removed and installed the heating system in a day, took pride in their work and took the time to explain the new system and to fully answer all my questions. Bruce and Bill clearly like what they do for a living, have great people skills and work very well together. I was able to get the very best of products and still come well under budget. I cannot thank these guys enough! Honest, Professional and Reliable! My dusty, unfinished basement with my new Viessmann boiler, Carlin burner and HTP indirect fired water heater is now my favorite part of the house!"

"Had a client in a multi family situation who needed a tremendous amount of existing cast iron replaced in one day. Matthew was hired to remove and replace with new pvc. Got it done in a timely manner so residents would not be down all day and could turn the water back on quickly.Would highly recommended to anyone with all plumbing repairs."

"Needed failed hot water heater replaced. Campbell installed a new replacement the next day after being called. Two installers plus the business owner showed up on time and quickly made the swap. Will definitely use again for plumbing need."

"I was very pleased with my experience with Griswold Plumbing, they installed a new shower faucet/showerhead and later a water treatment system. They were prompt, very professional, and courteous going the extra mile when needed. I highly recommend Griswold Plumbing and won't hesitate to call them again."

"I called and asked for an estimate to convert my DHW from the oil boiler tankless coil to a 50 gallon A.O. Smith Hybrid water heater. The owner gave me an estimate same day and was able to do the installation later in the week after calling him last minute. Him and his crew were on time, very quick, extremely OCD on pipe placement and appearance of their work, and tested everything before they left. I made things difficult on them with the short timeframe and having the electrician here at the same time but they didn t complain and worked great with the electricians to get the project done for us. I had 8 different companies give me estimates and hands down they were best pricing, most honest, and friendliest company I worked with!"

Water Heaters FAQs, answered by experts

You can use multiple tankless water heaters, but that doesn’t mean you should. Adding multiple tankless heaters adds considerable cost to your home in both parts and installation costs. Also, you’re adding many more points of failure in the system, making plumbing issues harder to diagnose. More heaters mean more maintenance, and insurers may want a word regarding the increased risk of water damage. A single, larger unit makes more sense in most situations.

Your water heater's age can affect your homeowners' insurance policy. Many policies will ask how old the heater is when you first apply for a policy—and they may make you replace a model that's over 10 years old. 

Even if your policy permits you to have an older heater, it may significantly reduce the amount of protection available. If an older water heater suddenly leaks and causes damage to parts of your home, your policy may not cover it.

Tankless water heaters heat water as it passes through the unit instead of storing heated water in the tank. Their ability to produce hot water on an as-needed basis makes them more efficient. However, they are generally more expensive than traditional units. Is a tankless water heater worth it? Most homeowners will save money with a tankless unit in the long run by using less energy.

While heat pump water heaters are more expensive than gas-powered water heaters, the ROI is higher for heat pump units. Not only are heat pump water heaters more energy efficient, meaning immediate savings on your energy bill, but they also last longer than traditional gas versions, meaning you won't have to buy them as often.

When installing a new furnace, it's a good time to consider other projects that can enhance your home's energy efficiency. A great first step is to get a home energy audit, which will identify areas for improvement. Common recommendations include sealing or replacing windows and adding insulation to the attic. These upgrades can help you save money on monthly utility costs. You might also consider installing a smart thermostat to make heating your home more convenient and efficient.
