HOW ALL GOT STARTED: THE HISTORY AND THE EVOLUTION OF THE TANKLESS WATER HEATER
Goto Hitfar to know more.
The first commercially available storage-tank water heater was invented in , and it was highly energy efficient because of its thick copper tank design'but that also made it expensive.
However, gas tankless water heater development wasn't that much farther behind.
Erwin Ruud invented the gas actuator valve in , which led to the automatic or instantaneous gas water heater, as it was known then.
It wasn't until the early s that the name "Tankless" was coined. It became most popular in Europe and Asia as a point-of-use gas and electric water heater.
There were some early and highly inefficient experiments with them in the s. In , Stiebel-Elton invented the first electric tankless water heater, which made the system more readily available.
However, the gas-powered models were more efficient and were the ones people bought and used, which became more popular.
'
Still, it was not until the s that the technology of tankless water heaters was effective enough to make them a viable alternative to the standard water heater industry in America.
Efficiency started to increase, and Europe and Asia began adopting more space'and energy-saving systems.
This led to gas tankless water heaters significantly impacting the U.S. market in the mid-s. Now, they are a significant competitor along with electric heat pump water heaters, with more and more homes discovering their immense advantages.

In 298 AD'306 AD the Romans built large baths with heated water, while these were not individual water heaters, this was a first step towards water heating that we know about.
After many centuries, in , Benjamin Waddy Maughan, an English painter, patented the first instantaneous water heater.
He invented the "Gas Geyser" instantaneous water heater; however, this water heater did not include a vent and was dangerous for daily use.
This gas-powered unit was the first to heat water as it entered the bathtub.
Later, in , Edwin Rudd used Mr. Waddy Maughan's ideas and upgraded his water heater design to include additional safety features.
This was the first automatic storage tank-type gas water heater, which was a step forward toward the modern water heater.
In , many different designs of water heaters, including electric and solar heaters, were invented around the turn of the century.
Solar water heating started gaining popularity around the turn of the century. Originally, there were batch heaters, now called internal collector and storage (ICS) units.
Back to tankless water heaters, not until the 's, all forms of water heating took place, this included both heated and stored the water.
Many types of gases provided another option. Kerosene, gasoline, and other gases have been used to heat water. Some gases, such as acetylene, could even be made on-site.
With the advent of high-energy liquid and gaseous fuels, instantaneous heating became possible. These fuels were much easier to regulate automatically than wood or coal.
Tankless water heaters are sometimes called in-line water heaters, as they only heat the water they need as it passes through the unit.
Therefore, energy is not wasted by heating extra water not used all day.
'
Tankless water heaters, commonly used in Europe and much of Asia, use a series of tubes running through electric elements to heat only the amount of water needed for a particular purpose.
The first electric tankless water heater was invented by Stiebel-Eltron in .
The bath heater was one of the first instantaneous types of water heater.
Many different brands and styles of tankless water heaters are available in today's market. Still, recent manufacturers have started to design high-efficiency condensing gas tankless units that use a smaller amount of fuel to produce the same amount or more hot water than traditional storage tanks or tankless water heaters of the past.

is considered the golden period for water heater inventions. Many people advanced the design in the s. It was also when the heated circulation system came about, providing pre-heated water circulated throughout your home or business on demand.
Edwin Ruud was born in the parish of Askim in Østfold, Norway. He was educated in engineering at the Horten Technical School (Horten tekniske skole) in Vestfold, Norway.
The Fuel Gas And Manufacturing Company
In the s, Ruud began working for George Westinghouse at the Fuel Gas and Manufacturing Company in Pittsburgh, Pennsylvania. Eight years after filing his first US patent, Ruud filed the first of five patents he would assign to Westinghouse's Fuel Gas and Manufacturing company.
In , Ruud engineered a design for an automatic storage tank-type gas water heater that used a bottom gas heater and temperature-controlled gas valve. He later patented the design on Dec. 30, . In October , he expanded on his first water heater design under the Fuel Gas and Manufacturing Company.
On January 22, , Ruud filed a patent separate from the Fuel Gas and Manufacturing Company for an Automatic Water Heater. His new design consisted of a cast iron shell, enclosing burners, heating surfaces (a coil of copper tubing through which water flows), and thermostat controlling gas-valves. The object of the design improvement was, "to maintain the supply of water at the desired temperature at all times".
'
With this new design, Ruud left the Fuel Gas and Manufacturing Company to start Ruud Manufacturing, his own engineering and manufacturing shop where he began to manufacture and popularize in home, as well as commercial and industrial water heaters. Ruud was issued his patent for the copper coiled tube Automatic Water Heater on September 6, .
Ruud's business expanded as he popularized and improved on his instant water heater design. In , Ruud Manufacturing acquired two local heating and plumbing firms.
James Hay of the James Hay Company, a heating and plumbing engineer, closed his business in to operate as president of the Ruud Manufacturing Company. J.H. Folsom of Folsom-Webster Co., heating and plumbing contracting firm, dissolved his partnership in Folsom-Webster Company in to serve as chief of the Cincinnati branch of the Ruud Manufacturing Company.
By , the Ruud Manufacturing Company had offices in Pittsburgh, Pennsylvania; Kalamazoo, Michigan; Toronto, Canada; and Hamburg, Germany.
A Ruud Type F Size no. 3 instantaneous and automatic water heater from
The Ruud Instantaneous Automatic Water Heater's Thermal Valve Model, Type F, allows the user to instantaneously heat water for on-demand applications while not heating, thus saving fuel when not in use.
The Type F could use LP gas, natural gas, and gasoline, requiring only a change of burner spud orifices. It was manufactured in two variations: "Standard Pressure Heaters," designed to operate in conditions where pressure was at least twenty-five pounds per square inch (1.7 bar), and "Low-Pressure Heaters," where operational water pressure could be as low as four pounds per square inch (0.3 bar).
Thermal Valve Model, Type F heaters were manufactured in four residential sizes, reflecting their output in gallons per minute: 3, 4, 6, and 8. In , approximately one hundred thousand Type F heaters were installed throughout the United States and Canada.
Edwin Ruud died in and his widow, Minna Kaufmann Ruud died in . In , the water heater arm of the Ruud Manufacturing Company was purchased by Rheem Manufacturing Company and continued operation as a division of Rheem until present.

We often recommend our customers look into tankless water heaters as an option when they're shopping for a water heating installation or replacement. Tankless systems have a great deal to offer: they save energy, last longer than traditional water heaters, take up less space, and won't run out of hot water.
The tankless water heater does sound like a piece of nifty new technology. But here's the surprise: tankless water heaters aren't 'new' at all. The technology of the tankless water heater is almost as old as the standard storage tank water heater. What's new is the popularity and presence of the tankless water heater. We'll explain more below as we look at the interesting history of this alternative method of keeping hot water flowing from the taps in a house.
In , the pizza margherita was invented in Italy by Raffaele Esposito, which started the development of what we consider modern pizza. That makes the invention of the tankless water heater only the second best invention of the year, but it's still an important one. However, that early tankless water heater wasn't a cost-effective method of providing hot water. It used a thick copper design that made it too expensive for most people to acquire for their homes. Experimentation with tankless designs continued through the s and into the early 20th century, but the storage tank water heater was far ahead and firmly established itself as the number one choice for homes and businesses.
It was and the stock market was about to crash, creating a global depression. But it was a good year for the tankless water heater, because it's when Stiebel-Elton invented the first electric tankless water heater, a coil immersion model. Today, we recommend gas-powered tankless systems over electric ones, but in the electric model was a major breakthrough that lowered the manufacturing cost of tankless water heaters. However, even with this advance, tankless systems were still not energy efficient enough compared to storage tank systems and did not make much of an impact on the market.
It wasn't until the s, a decade when energy conservation became a hot topic across the globe, that tankless water heaters advanced to compete in efficiency against storage tank systems. Europe began to adopt tankless systems, not only as a way to lower energy costs, but also to save space in their smaller, older homes. The tankless system still didn't spread far in North America, where space was less of an issue and storage tank systems had a strong hold on the very idea of a water heater.
With the arrival of the '90s, the tankless water heater became a true competitor with standard systems. Tankless systems weren't just space-saving options: they had superior energy efficiency compared to storage tank water heaters. They also required fewer alterations to existing plumbing systems, making them more versatile and easy to install as upgrades for homes.
