"Had called around to a dozen local shops because my water heater went out and I needed a replacement. Rock Solid plumbing came with a bid that matched the closest competitor, but it was with a much better and more efficient water heater. The owner brought by a few informational guides and explained the benefits of one model versus the other, and once we had decided on using Rock Solid Plumbing, they were there within the week and had plumbed everything neatly two days ahead of schedule. Can't recommend these guys enough."

"Excellent customer service, and quick install! I've only had the product (tankless water heater) for 1 week at the time of writing this, but so far it's great. I chose this company because of the customer service I received. I expect it will remain as good when service is needed, and I'm confident in the quality of the product chosen. Thanks again!"

"Moore removed and replaced my water heater in mid November. First class work performed and no issues with it since. Had the duct work cleaned for the first time and while pricey worth knowing they’re clean of debris."

"I have a multi family building that needed the furnaces to be services and I wanted all of the thermocouples replaced in the furnaces and water heaters. Wagner provided a reasonable quote, completed the project when he said he was going to, and contacted all of the tenants to schedule the work. Defiantly will be doing business with them in the future!"

"I called this company on Tuesday and Don came out promptly at the time agreed to look at my project that afternoon. He gave me a fair quote and said he would return on Thursday with the necessary tools and parts to fix my hot water boiler tank that was leaking and to replace a kitchen faucet that could not be turned off. I had been told by three other plumbers, that the kitchen sink faucet was going to be really hard and expensive to replace because the previous faucet had been installed incorrectly and a brass fitting smashed on. They all said the sink would need to be removed and the under sink plumbing cut out and replaced. Don showed up right on time Thursday and went right to work. In less than 15 minutes he had the job done. He said it did require a special tool to remove the faucet, which he had, but it was not really a problem. No sink removal or plumbing replacement needed. Then he tackled the replacement of the leaking boiler hot water tank. This portion of the job took over four hours and proved to be a beast. Unintimidated, Don tackled and completed the job efficiently. I did notice when I was finishing the clean-up and putting my things back in the room after he was done that there was still a minor drip. I contacted Don and he came back the next morning and discovered one of the O-rings in a dielectric union had broken during the install and needed to be replaced. He immediately fixed the problem and I now have both of these issues resolved. I will definitely call Don again for future handyman projects, especially plumbing repairs. He is prompt, reliable, professional and fair."

"I have only lived in the Valley for 3 years and was recommended to J&S by a realtor who swore by their professionalism. I have hired Jimmy and his crew complete 2 jobs for me. They installed a hot water tank and fixed a plumbing leak in my master bathroom. I could not ask for better service. They were on time and completed the job quickly and efficiently. I highly recommend J&S Plumbing and Heating for any jobs you may need. They have integrity, the cost is affordable and less than other local companies. The office staff are kind and professional. I could not be happier!!!!! -Nate & Ree Ann Palmer"

Water Heaters FAQs, answered by experts

Every type of water heater has its advantages and disadvantages. Understanding those can help you decide the best type for your situation and budget. 

Pros

  • Safer than gas or propane

  • Doesn’t require extensive venting systems

  • Lower upfront costs

  • Simpler to operate

  • No pilot light

  • Easier installation

  • More efficient heating than gas models

  • Available as point-of-use (POU) and whole-house units

Cons

  • Slower to heat water

  • Longer recovery time

  • Possibly higher operating costs

  • Doesn’t work during a power outage

  • Costs can increase without a 240-volt connection

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.

The right way to vent a gas water heater is to have a pipe directly upward or slopes upward out of the house. Because hot air naturally rises, this type of venting will efficiently ensure that all gas moves out of the house. Your system may rely on fans or blowers as well.

It’s important to find the type of water heater that fits your needs and budget. Depending on the type of water heater, size, brand, and the type of energy you use to heat the water, costs range from a few hundred dollars to several thousand. Some of the most common types of water heaters include:

  • Electric: $600–3,500

  • Gas: $700–$2,700

  • Propane: $700–$2,500

  • High efficiency: $1,500–$3,000

  • Indirect: $1,200–$3,500

  • Hybrid heat pump: $1,200–$3,500
