Is A Whole-House Tankless Water Heater The Right Fit For You?

October 5, 2020

Water Heater Services - Save Home HeatWith steady advances in technology, capabilities, and reliability, whole-house tankless gas water heaters continue to grow in popularity with homeowners in the Denver-Boulder area. Our team would like to take this opportunity to revisit the benefits provided by tankless water heaters while taking a closer look at some of the details that contribute to this growing trend with our customers.

Tankless Water Heaters: A Recap

Some of the benefits of whole-house gas tankless water heaters are well-known, contributing to their growth as a hot water option for homeowners in the Denver-Boulder area and surrounding communities. From taking up less space than traditional tank-style water heaters, to having a much longer projected lifespan, there are plenty of reasons to consider a tankless model over a standard water heater. Saving money on hot water costs due to higher energy efficiency is a big plus, too!

Primary benefits of tankless water heaters:

  • Very high efficiency
  • Saves valuable floor space
  • Virtually endless supply of hot water (with a properly sized system)
  • No storage tank to keep hot 24/7
  • Much longer projected lifespan than tank-type water heaters
  • Reduced fossil fuel consumption means smaller carbon footprint

While these advantages are enough for many homeowners to consider a tankless water heater, there are even more benefits to dig into. Let’s take a closer look at some details.

Specific Advantages of Whole-House Gas Tankless Water Heaters

Efficient, Safe Operation

Certain models that we install are so efficient that, like high-efficiency furnaces and boilers, they are classified as condensing heaters, and their vent systems are specified to use Schedule 40 PVC plastic pipe. The sealed combustion venting design that’s common in virtually all units helps keep operating sound levels at a minimum while using only outside air in the burning process – the safest and accepted standard for all types of high-efficiency gas heaters.

Energy Star HVAC ProductsThe tankless water heaters we install only burn as much gas as is needed to meet your immediate hot water needs. Featuring an automatically adjusting gas control, these systems only operate at full capacity when demand requires it. The rest of the time, they use less gas and run even more efficiently. In fact, the Uniform Energy Factor (UEF) ratings of our most popular high efficiency and super high-efficiency models range from approximately .8 UEF to .95 UEF (the super high-efficiency models are ENERGY STAR certified), far more efficient than popular standard tank systems, whose UEF ratings range from .60 to .65.

During operation, electrical consumption is less than a 100 watt light bulb!
Low Sound Levels

Most models have very low sound levels when operating. When not operating, they are silent. The two high-capacity units that our team often installs have sound ratings of 47dB and 48dB, described by various sources as somewhere between a quiet library or a babbling brook on the low end, and a refrigerator, conversation, or ‘ambient urban sound’ on the high end. Smaller capacity units are even quieter.

Compact Size

As a general rule, tankless water heaters are wall-mounted, very compact, and lightweight (approx. 50 to 75 lbs.). The most popular models that our team installs are high-capacity units with gas ratings of nearly 200,000 BTU/hr. Their dimensions range from approximately 14” to 19” in width; in height, from 27” to 32”; and in depth (extending off the wall) from only 10” to 12”. Talk about compact and packing a big punch!


Certain models have the ability to be installed in a hot water recirculation system, for the fastest hot water delivery possible. In addition, many models offer remote WiFi monitoring and management capability, making your hot water experience incredibly convenient. A number of tankless water heaters offer great flexibility in the use of indoor and outdoor combustion air, as well as the length allowances and configurations of the vent piping. Along with natural gas models, we can also assist you with propane-fired units.

Tankless water heater benefits also include:
  • Many models are ENERGY STAR certified
  • A broad range of applications and flow rate capacities
  • Automatic, pilotless ignition systems on all models
  • Modulating gas valves to accurately dial-in desired output temperature
  • Quiet, safe operation with sealed combustion venting
  • Extremely versatile venting in some models
  • WiFi capability in many models!
