"The boiler was fairly new, but had never been serviced. The workman came on Saturday in response to an emergency call, and fixed the boiler as well as performed basic maintenance which badly needed to be done. He didn't bleed the radiators, so I will be contacting the company to make arrangements to have that techs do this as well. I would consider relying on Vitt's for routine maintenance of our heating system, as well as replacement of our water heater."

"We had Jones Air & Water come out to install filtration and replace a catalytic core system that we had installed to prevent descaling. In our situation, we had a high volume of Chlorine in the water that you could definitely smell and taste. The catalytic core system, didn't live up to the expectations and we still had to deal with a heavy scale build up noticeable on all of our faucets and with two Rinnai units for on demand hot water that raised concerns about what type of build up we were having on what we couldn't see. Everett came out and was very thorough in testing the water and then explaining a recommended solution. We finally decided on a dual media tank solution that Everett and JD installed that provides us with an efficient way to not only handle the Chlorine issue, but truly conditions the water and we're noticing all of the differences that Everett explained we should see. We are very satisfied with the whole process from the review of what our situation is, the recommended solution, the installation and the end result. We highly recommend using Everett for a water treatment solution."

"I purchased the $30 promotion for a hour of service. The owner showed up with an employee. They installed the water heater and unclogged the drain in 2 hours. I paid $170 plus the $30 promotion through Angie's List. I saved over $500 compared with the plumber that I had previously planned on using. I had a small connection problem on the water heater. I contacted the owner and he arrived at my house a couple hours later, 8:00 pm. I was completely satisfied and plan on using Froggy's in the future.

"Everything went really smoothly. The acrylic product they use is of high quality. We had some concerns about our tub walls being a little spongy due to water demand, but they reinforced everything. The job was done in one day as promised. The end result as far as appearance exceed my expectations."

"My experience with the Spengler Company was great.  Colby arrived at my house on time and then proceeded to perform the cleaning of my air conditioning unit.  He found that our refrigerant was low so he filled that up.  And he also changed our air filter for FREE!  He then gave me six options to replace the water heater in our home.  It was over 20 years old and had been leaking on the floor.  We selected the second option and he called it in and our water heater was changed out the same day!  WOW.  What service!  We couldn't be happier.

Water Heaters FAQs, answered by experts

Newer models are packed with newer technologies that decrease energy consumption and increase output, giving you more bang for your buck in more bills than one. 

If you’re trying to decide whether you want to repair or replace your new heater, consider factors like your utility bills, repair costs, and even your carbon footprint to help you decide whether it makes sense to buy a new one instead.

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.

Tankless water heaters are more expensive than those with a storage tank, but they come with some impressive benefits that most homeowners find worth the higher investment. Most importantly, they provide unlimited hot water, so you’ll never run out like you would with a storage tank. Tankless heaters are also more efficient, so comparing gallon-for-gallon, you’ll spend less on hot water with a tankless heater. Tankless water heaters are also smaller, require less maintenance, and tend to last longer than storage tank water heaters.

When the water expands in a hot water heater, it puts pressure on your hot water pipes and can cause leaks or a rupture in the hot water tank under certain conditions. Pipes or water heaters may split due to the pressure where there is a backflow preventer that prevents the hot water heater from diffusing pressure by releasing water back to the public water line.

In these scenarios, a hot water heater expansion tank provides a place for the hot water heater to relieve pressure and prevent bursts and leaks.

It is very difficult and dangerous to install your own water heater, so we strongly recommend against tackling this as a DIY project. Not only will you need to wire your water heater, but you’ll also need to connect plumbing to the intake and outlet. Sweating copper pipes and connecting wiring properly are skills most DIYers don’t have, and even if you do feel confident you can do it, working with water and electricity always leaves the potential for electrocution. Hiring a local water heater installer is well worth the investment.
