Considering an upgrade to your water heating system?

Considering an upgrade to your water heating system? Tankless water heaters are a game-
changer in home water heating. Understanding the ins and outs of tankless technology is key, so
let’s explore the pros and cons of these devices together:


  • Tankless units are High-Efficiency devices, typically operating anywhere from 15
    – 30% more efficiently than standard tank water heaters
  • Tankless water heaters are very responsive to a client’s hot water needs, quickly
    making the hot water needed, no warm-up time or large tank to heat up
  • High-efficiency gas tankless water heaters offer a near-endless supply of hot
    water. Rather than storing water in a storage tank, gas tankless water heaters heat
    water directly through the pipes — no tank required.
  • No atmospheric vent to downdraft exhaust gases back into the house, or allow
    heat out of the house when not operating
  • Can be easily paired with additional units to match your specific hot water needs
  • Removing the large tank frees up mechanical space and floor space by providing a
    smaller footprint and a wall-mounted design
  • When properly maintained with annual maintenance, these units will provide long
    life expectancies and optimal working efficiencies


  • Without storage capacity the units do have a limited amount of temperature rise
    and flow that they can provide, which may not be enough during heavy use
    periods or if the home has high draw fixtures. Multiple units may be required.
  • Use larger amounts of gas, so gas piping has to be verified for proper sizing and
    capacity when upgrading from a standard water heater
  • Hot water recirculation systems must be placed on timers to limit the recirculation
    system’s operation.  Continuous operation of hot water recirculation systems will
    shorten the life of the equipment
  • Venting units can be a challenge when upgrading systems from traditional water
    heaters, but it is usually manageable

Beyond the surface, tankless water heaters offer a multitude of benefits that resonate with
modern homeowners seeking to optimize their living spaces:

         Advanced Technology

Through innovative heat exchangers and precise temperature controls, these units deliver hot
water swiftly and sustainably. Additionally, many models feature advanced digital interfaces that
empower users to monitor and adjust settings with ease, providing an intuitive user experience
that aligns with contemporary lifestyles.

        Environmental Sustainability

In an era defined by heightened environmental consciousness, tankless water heaters emerge as
champions of sustainability. By operating only when hot water is needed, these units minimize
energy wastage, reducing carbon footprints and contributing to a greener future. Additionally,
their durable construction and extended lifespans mitigate the need for frequent replacements,
further lessening environmental impact and fostering a culture of responsible consumption.

       Financial Savings

While the initial investment in a tankless water heater may seem daunting, the long-term
financial benefits far outweigh the upfront costs. By slashing energy bills through heightened
efficiency and reducing the need for maintenance and replacements, these units offer compelling
returns on investment over time. Many regions offer incentives and rebates for transitioning to
energy-efficient appliances, further sweetening the deal for homeowners looking to make the
