REVIEWS
“John and Marcelo were wonderful. We went from having a leaking hot water heater to a brand-new one in less than 24 hours. I would highly recommend using High 5 plumbing.”

“Justin was such a nice person and a great plumber. He cleaned and flushed our tankless hot water heater efficiently. He even let me know how I might repair a corroded piece on our tankless water heater myself in the future. Very polite and sweet to our dog to boot :)”
Cashin W.
“Daniel was great. He came to our home to do an assessment of our water tank and conversion to a tankless water heater. He was very professional and knowledgeable in assisting us and getting our questions answered.”
Christopher H.
“Justin was very professional. He answered all our questions and gave a thorough description of the steps involved in installing an electric tankless hot water heater. Would definitely use High 5 and Justin again.”

Benefits of Installing a Tankless Water Heater
Investing in a tankless water heater can help you benefit in the following ways:
- Plenty of Hot Water: The heating elements turn on when you open the hot water faucet, providing an endless supply for as long as it’s required.
- Energy Efficiency: Traditional water heaters continuously heat a tankful of water, even if you don’t need it, but a tankless model eliminates this energy load.
- Lower Utility Costs: Reduced energy consumption means a tankless water heater can lower your energy bills substantially.
- Longer Lasting: Tank water heaters typically last up to 12 years, while a tankless unit can last for up to 20 years if properly maintained.
- Smaller Size: A typical tankless water heater is about 28 inches tall x 20 inches wide x 10 inches deep (compared to a 60-inch-tall x 24-inch-wide tank), so it can fit in a smaller space.
- Simpler Maintenance: Tank water heaters require more frequent maintenance, but a tankless unit needs less depending on water quality; annual cleaning can often be completed without a professional, but having a plumber check it occasionally is a good idea.
