HOW ALL GOT STARTED: THE HISTORY AND THE EVOLUTION OF THE TANKLESS WATER HEATER
The first commercially available storage-tank water heater was invented in 1889, 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 1889, which led to the automatic or instantaneous gas water heater, as it was known then.
It wasn't until the early 1970s 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 1890s. In 1929, 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 1970s 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-1990s. Now, they are a significant competitor along with electric heat pump water heaters, with more and more homes discovering their immense advantages.

Now Let's Go Through The Water Heater Timeline
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 1868, 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 1889, 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 1890, 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 1890'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 1929.
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.

It's hard to imagine living without immediate access to hot water, but many people have in the past and even today throughout the world. Here are some more interesting facts about the history of water heaters.
-
In 298 - 306 AD, the Romans had large baths facilitated with heated water. Although not considered real water heaters, many consider them pioneering work in water heating.
-
Benjamin Waddy Maughan, an English painter, patented the first water heater in 1868. It was the first residential water heater. It used natural gases to heat the water but didn't have a flue to vent gas vapors, making it unsafe for households.
-
Waddy Maughan inspired Edmund Rudd. He advanced the design by adding safety features, which was the initial step toward the invention of the modern water heater.
-
In 1896, Clarence Kemp took things one step further with his solar-paneled heating. His invention used solar panels to heat water, a popular choice in sunny regions worldwide.
-
The modern tankless water heater made its debut in 1970.
-
1990 is considered the golden period for water heater inventions. Many people advanced the design in the 1990s. It was also when the heated circulation system came about, providing pre-heated water circulated throughout your home or business on demand.
The Tankless Was The First American Water Heater
Edwin Ruud's proof of patent, as shown, was dated Dec. 30, 1890
Biography
Early life
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 1880s, 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 1889, 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, 1890. In October 1890, he expanded on his first water heater design under the Fuel Gas and Manufacturing Company.
Ruud Manufacturing Company
On January 22, 1897, 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, 1898.

Ruud's business expanded as he popularized and improved on his instant water heater design. In 1908, 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 1908 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 1908 to serve as chief of the Cincinnati branch of the Ruud Manufacturing Company.
By 1915, the Ruud Manufacturing Company had offices in Pittsburgh, Pennsylvania; Kalamazoo, Michigan; Toronto, Canada; and Hamburg, Germany.
The Ruud Instantaneous Automatic Water Heater

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 1915, approximately one hundred thousand Type F heaters were installed throughout the United States and Canada.
Ruud Heating and Air Conditioning Equipment
Edwin Ruud died in 1932 and his widow, Minna Kaufmann Ruud died in 1953. In 1959, 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.
