"Tommy, the owner of TNT Services Plus LLC, was great to work with. He was quick to provide the needed information when I reached out for a quote and was able to fit us in right away. His work was done quickly and to a high standard. We needed the water heater to close on the house we were selling and TNT Service was a critical part in us meeting our deadline, and within budget!"

Moved to a new house and the water was yellow and stinky due to rust and hardness. Called Glaser Softwater and despite the owner being on vacation, they still took immediate action and had a rust remover and water softener installed within a few days. We’ve had water softeners in the past but Glaser has proven to be the best by far! Our water went from yellow and nasty to the best water we've ever had. I can personally attest that  there is a BIG difference amongst water softeners and Glaser Softwater systems are AMAZING! I would give them my best recommendation not only for a superior product but also for professionalism and excellent customer service.

"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."

"As the owner of The Pack, a grooming shop in Germantown, we ended up selecting Flow Force to address our plumbing needs. Upon opening, we discovered that our water heater was insufficient to support our water usage. We also found that Germantown's water is exceptionally hard, leading to the need of an installation of a water softener. Initially, we worked with another company, only to discover that they were overcharging and incorrectly advising us that installing a water softener and a larger water heater was not feasible due to space constraints and would ultimately be too expensive. Consequently, we had to obtain the services of a new plumbing team. Cole and his employees at Flow Force have consistently demonstrated professionalism throughout all projects. He accommodated our business hours, which was a huge help in minimizing disruptions to our business. They surpassed our expectations, and we now enjoy optimal hot water pressure."

Water Heaters FAQs, answered by experts

The time it takes to install or replace a water heater depends on the type of heater and the complexity of the job. A professional can typically replace a standard tank-style water heater in one to three hours. However, if the work area is tight, such as a small closet or crawl space, the job could take four to five hours. Replacing an existing tankless unit takes about two to three hours, while upgrading from a tank-style to a tankless water heater is more complex and can take four to six hours. The project will take longer if you are switching fuel sources, such as installing a gas heater which can add about an hour to the timeline, or if the unit needs to be relocated.

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.

Water expands when heated and also when freezing. When water is heated, it expands by around 4%. For a full water heater, this is one of the main reasons malfunctions occur—the hot water has nowhere else to go but out. Due to the constant expansion and reduction in volume, it’s recommended (required in most places) that an expansion tank be installed.

The average cost to replace a water heater is around $1,325, with a typical range of $900 to $1,800 for a standard replacement. The final price depends on the type of heater (tank vs. tankless), its size, fuel source (gas or electric), and the complexity of the installation. A simple one-to-one replacement will be on the lower end of the cost spectrum. However, if you are switching from one type of heater or energy source to another, you can expect labor costs to be significantly higher due to the extra work involved. It's also worth considering that while gas and electric heaters may have similar upfront costs, their long-term operating costs can differ based on local utility prices.

You have more options for water heaters than ever before. The best one for your home depends on your hot water usage and budget. Some of the more common types of water heaters are the conventional gas heater, a heat pump water heater, or a tankless heater for smaller homes or those with less water demands. Some uncommon types are solar and point-of-use systems. Some homes may have a combination of two units, such as a large heat pump heater and a backup point-of-use system.
