Residential Water Heaters

Next to the heating system, a water heater is the largest consumer of energy in a home. To help choose the correct model, you need to do more than compare prices.

Although the cost of a water heater is important, you should consider the hot water requirements, usage patterns and local energy costs. The right mix of these variables will lead to a satisfying purchase.

These are the Facts

  1. 25% of every American household energy dollar is spent producing domestic hot water.
    • Nationwide more residential energy is consumed by domestic hot water than on anything but heating, and air conditioning.
  2. Electricity is the WORST way to heat hot water while natural gas and propane gas are much more efficient, smarter choices.
    • Based on national fuel price averages of $1.46/ccf and $0.09/kwh, the cost/100,000 BTU's is $1.46 for natural gas and $2.64 for electricity. Just under 60% of North American households have access to natural gas, and if you don't, propane gas is available to almost everyone and is still a better value than electricity. In addition electric water heaters have only a small fraction of the capacity of gas water heaters. So if you like expensive, short showers, with cold water at the end, use electric; otherwise gas would be a better choice.
  3. Modern gas fired tankless water heaters are the best alternative available to today's homeowners to reduce their residential energy consumption.
    • A typical gas fired tankless water heater costs about 2-1/2 times as much as a standard tank water heater. However it will pay for itself in just a few years or less, and will last twice as long as a tank.
  4. If you are considering a tankless water heater Rinnai is clearly your best choice. On average a new Rinnai is installed somewhere in North America every 3.75 minutes.
    • Rinnai has shipped over 30 million tankless water heaters world wide. Click Here to find out more about the Rinnai story.

What is a tankless water heater?
Tankless water heating systems are revolutionizing the way modern homes meet their water heating needs. These compact units can produce and supply endless streams of hot water to multiple outlets at once without any fluctuation in temperature.

Rinnai Tankless Water Heater Rinnai Unlike antiquated hot water tanks that heat and reheat the same water 24 hours a day, Rinnai's on-demand water heater technology is more efficient because it only heats water when it is needed. When a hot water source is opened, Rinnai senses the demand and starts delivering continuous hot water. When the hot water source is closed, the tankless water heating unit shuts off. That means no more heating water when you don't need to.


RC98HPi Rinnai's unique condensing design incorporates two innovative heat exchangers to achieve optimum heating value from every cubic foot of natural gas or propane. The stainless steel system recaptures residual heat from flue gases to pre-heat incoming ground water, which then circulates to the primary copper heat exchanger.

Delivering up to 97% thermal efficiency, Rinnai's tankless condensing units are ideal for residential and commercial applications and can be banked for even greater capacity.

Circulation Loop

Tired of waiting for hot water at your shower or sink?
Feel guilty about wasting water while you wait?

The Grundfos Comfort System brings savings and comfort to your life by giving you hot water in an instant from any source in your home. This efficient hot water recirculating system keeps water constantly hot-saving you water, money and precious time.

In typical plumbing, water flows from the water heater through the pipes to the tap. Once the tap is shut off, the water remaining in the pipes cools—resulting in the familiar wait for hot water the next time the tap is opened. Many gallons of water are wasted—and so is your time. The Grundfos Comfort System offers a simple and affordable solution by attaching a hot water recirculation pump to the water heater through the hot water pipe. The pump keeps the water in your pipes moving, giving you constant hot water-without the wait or the waste.

With hot water in an instant you'll enjoy more and waste less.

Savings and Payback

How many stop to think what happens to the 2-3 gallons that run down the drain during the wait?

Those gallons of water are wasted, and in an average household that takes four showers per day, that can add up to thousands of gallons per year. Multiplied by a subdivision of 300 homes, a community can have millions of gallons of water go down the drain into the sewer system every, single year. Hot water recirculation means hot water in an instant without unnecessary waste. Payback will result from the reduction of water usage, and water waste.

Standard Tank Water Heater

A simple water heater...


With new industry-wide design changes like the Defender Safety System™, today's water heaters are more complicated than ever. Proper installation and service require that water heater manufacturers provide training and education.

This valuable knowledge is only available to a professional installer.

Bradford White offers a wide array of both natural and LP gas-powered water heaters for residential use. These durable products provide years of dependable service and are designed to give you more hot water for the money.

Bradford White water heater Bradford White The residential, gas-powered, conventionally vented water heater stands as the time-tested workhorse in the industry. Unlimited flows rates and large standby supplies of hot water have helped make this design the most popular style across a diverse geographic area. Whether powered by natural or propane (LP) gas, this venerable and familiar style has undergone considerable change in recent history. The most important change was the incorporation of Flammable Vapor Ignition Resistant (FVIR) technology.

In the U.S. where large, multiple and simultaneous hot water demands necessitate high flow rates, the large, stand-by hot water reserve a tank-type heater provides remains a prized attribute. The operating and energy efficiency of these water heaters continues to improve across the industry and now is approaching or surpassing the efficiencies of any other residential water heater design.

Conditions hard water without salt or chemicals

Helps prevent and reduce hard water problems throughout your home

ClearWave — Water Conditioner

ClearWave The ClearWave™ Water Conditioner is the solution to scale buildup due to hard water. Virtually eliminating scale build-up in pipes, faucets and appliances.

This revolutionary new product works without chemicals, salt or plumbing to help reduce scale buildup and prevent scale formation. The ClearWave-HD works on all types of pipe including copper, PVC, galvanized and stainless steel.

  • Helps reduce unsightly stains on bathtubs, toilets, shower heads, etc.
  • Kitchen appliances operate better without scale.
  • Helps reduce use of soap and detergent.
  • Water heaters are more efficient without scale.
  • Since no chemicals or salts are added, you may drink ClearWave treated water.

Pure water contains nothing but H20
But water, as it comes out of the ground, is rich in a multitude of minerals. Minerals such as calcium and magnesium are the main components of hard water, and the cause of scale formation and other problems.

How it Works
The ClearWave-HD Water Conditioner generates a series of inaudible wave forms that affect calcium crystals in water so that they are unable to stick to anything. These "enhanced" microscopic particles then contact existing scale and cause it to loosen, break down and flow easily with the water.
