Why Upgrade to a Tankless Water Heater?

There's never a good time to run out of hot water—especially if you're halfway through a shower. But there is a way to make sure you always have hot water on hand no matter how much your household demands it. With a tankless water heater, you can have instant access to all the hot water you need. And that's not the only benefit they provide: they take up a lot less space, have a longer lifespan, save energy because they don’t have to keep a tank full of water heated around the clock, and ultimately save you money in operating costs in the long run.

If you’re in the market for a new water heater, you have a number of different options, from the traditional gas or electric tank models to an energy-saving tankless version. But this is a significant investment to make, and it's not always easy to tell which type is best suited for you and your home. That’s why the plumbers at ARS/Rescue Rooter are always available to provide a no-cost analysis of the tankless water heater pros and cons and help you decide on next steps. If you do decide to go with a tankless water heater, you can expect higher upfront costs—but the long term advantages might fit better with your needs and budget. Our plumbing company can install your new unit and get you started on the road to savings as soon as possible.

How does a tankless water heater work?

Whether you have a gas or an electric tankless water heater, it’s capable of supplying your home with an almost endless supply of hot water on demand. Without a tank, the water is instantly heated as it passes through the device. That means there is less energy spent on maintaining a high temperature for water that isn’t being used.

Just like any other appliance, there are a few components that keep your tankless water heater going. Regular maintenance will make sure these parts are in good condition:

  • Heat exchanger: Made of copper tube or stainless steel, a small quantity of water is stored inside, transferring the heat to the water that is flowing through.
  • Safety features: Includes sensors to detect temperature and water flow, fan speed monitoring and a valve for pressure relief.
  • Combustion elements: In gas units only; includes a combustion chamber, gas valves, and combustion fan.
  • Venting: Gas water heaters vent air out using a direct vent, power vent, or atmospheric vent.

Tankless Water Heater Repair

You’ve already made the switch to a tankless water heater, so you’re enjoying advantages like a smaller unit with a longer lifespan and more cost and energy efficiency. But that doesn’t mean your tankless water heater will never run into issues. Luckily, ARS/Rescue Rooter can help with that. Our expert plumbers know how to repair all kinds of water heaters, including tankless, so give us a call and we’ll help you enjoy more comfort—and hot showers.

Although tankless water heaters are generally reliable, there are a few reasons you might be experiencing lukewarm or cold water. If you have hard water, over time, the minerals might clog up the openings and need to be cleaned out. Tankless water heaters generally need to be flushed out every six months to two years, depending on the quality of your water and the effects of regular wear and tear. Give your local plumber at ARS/Rescue Rooter a call and we’ll be happy to schedule a convenient time to make sure your water heater is working as efficiently as possible.

Tankless Water Heater Maintenance

There are plenty of benefits to having a tankless water heater. Not only do they take up less space, but they also tend to last a lot longer, saving you money and energy in the long run. That being said, regular tankless water heater maintenance is still important to keep it running smoothly for as long as possible. The qualified plumbers at ARS/Rescue Rooter are happy to give your tankless water heater a tune-up—just give us a call and we’ll make sure your water heater is working properly. To keep your tankless water heater running well, it’s important to do two types of regular maintenance: checking the in-line screen filter for debris and flushing the unit to keep it free of scale and lime, particularly in homes with hard water and without a whole home water softener system.

Give ARS/Rescue Rooter a call at 866-399-2885 for advice on your best water heater options and expert repair and hot water heater installation.
