How Long Does It Take to Install a Tankless Water Heater 

On average, installing a tankless water heater takes about 4 to 8 hours, depending on the complexity of the job. If you're replacing an existing tankless unit with a similar model, the process is usually quicker. However, switching from a traditional tank-style water heater to a tankless system may take longer, especially if new gas lines, venting, or electrical work is needed. 

At O'Connor Plumbing, we carefully assess your home’s setup in advance to provide a clear timeline and a smooth, efficient installation.

7 Benefits of Tankless Water Heaters 

Tankless water heaters are a smart, energy-efficient upgrade for any home. Unlike traditional water heaters that store hot water in a tank, tankless systems heat water on demand, giving you greater efficiency, reliability, and comfort. 

Key benefits of tankless water heaters include:

  1. Endless hot water - Enjoy continuous hot water for showers, laundry, and dishwashing.
  2. Energy efficiency - Heats water only when needed, reducing energy use and lowering utility bills.
  3. Longer lifespan - Tankless units typically last up to 20 years or more with proper maintenance.
  4. Space-saving design - Compact and wall-mounted, tankless systems free up valuable storage space in your home.
  5. Cleaner water - Without a tank, there’s less chance for rust or sediment buildup in your water supply.
  6. Lower risk of leaks or water damage - No large tank means less risk of a catastrophic tank failure or flood.
  7. Environmentally friendly - Uses less energy and produces fewer greenhouse gas emissions over time.

FAQ

Find Answers To Your Questions
  • What can I put in my garbage disposal?
    Garbage disposals are not macerators and will only break up soft debris. Mashed potatoes, cooked carrots, eggs etc. are ok to put in the disposal. Things like bones, coffee grounds, egg shells or any hard product will wear the blades and jam the disposal. You should always run water to the disposal to help break down the foods and flush through the drain. Call the professionals at O’Connor Plumbing for help with your disposal
  • Is it safe to use chemical drain cleaners?

    Drain cleaners are very toxic. If you ever look on the back of the product you will notice at least 3 warning labels. These are not very good products to have laying around your house especially if you have kids or pets. These toxic chemicals are also very bad for your pipes, causing them to deteriorate from the inside out. If this happens your drain lines will need to be replaced. There are enzymes and friendly bacteria products that will keep grease and sludge from building up inside of your pipes.

    If you have a clog please call the professionals at O’Connor Plumbing!

  • Why does the toilet keep running?
    This is probably the most commonly asked plumbing question. In most cases it is caused by the flapper not closing on or making a proper seal around the flush valve. If the flapper is not closing, then jiggle the handle and that will normally fix the issue. If the flapper is worn out and not properly sealing, then you will have to have the flapper replaced. Either way if the flapper does not seal the water will leak into the toilet and the tank will not fill with water to push the float up and turn off the supply of water.
  • Do I need a tankless water heater?
    Tankless water heaters, while at the front of technology, aren’t the solution for every house. Sometimes you are better off staying with your conventional heater. Here at O’Connor Plumbing we have tankless water heater experts that can provide you with a tankless or tank style heater that best suits your home.
