There are so many different Browie models and variations of each model that a very extensive collection could be established consisting of Brownie cameras only, and even more so if you would include modern versions. Physically, an electrical cable is an assembly consisting of one or more conductors with their own insulations and optional screens, individual coverings, assembly protection and protective coverings. These conductor in form of a stranded wire which are insulated with a polymer (non-conductive) coating is a wire while a cable is combination of two or more shielded wired with a single cover which is used for generation, distribution and transmission of electrical power. An electrical cable can be used for the transmission of electrical energy but also for data transmission. Add in the long-term energy savings and your tankless heater just might pay for itself and in some cases it's replacement! If it is an electric tank water that you are replacing, your savings may be higher than 50% depending on the size of the tank. If you have a family of 6 that has never had enough hot water with a 50 gallon tank heater, your bill might just go up because now your family will not be taking cold showers or have to shorten them.

One very large company even went to the trouble of taking "their" new tankless water heater and putting against their tried and true gas fired tank water heaters in a "test". When I left home, this collection went by the wayside until years later I got back into collecting phones, first concentrating on Western and Northern Electric phones, then most recently Phillips/Automatic Electric. Automatic Electric. Unlike their Western and Northern Electric counterpart the 211, they were complete phones including network and not simply a "stand". Both phones were found in British Columbia - many have been preserved there, as BC Tel exclusively used Automatic Electric phones, and in fact, later owned the company as mentioned in the history above. The Brockville plant became known as GTE Automatic Electric. About half of them are electric. Long life and Heat Resistance : As the cables are installed every sector show they should require very less maintenance as it is not feasible to maintain them in public or private facilities.

Cables can be securely fastened and organized, such as by using trunking, cable trays, cable ties or cable lacing. This can be a product like CLR or a vinegar/water solution of one of the commercially available cleaners that boiler companies use to do the same thing with tankless coils in boilers. It did not take very long for this to get the attention of the big tank companies. However a 50-gallon tank heater only can really give you about 40 gallons of hot water per use before you begin running out of hot water. If you are going to change from a 50-gallon gas heater to a tankless you are probably not going to realize quite that much energy savings. While this was going on on the surface, they were behind closed doors with the lawyers striking deals with the tankless companies to have units private labeled for them in an effort to slow down their shrinking market share until they can catch up with the technology. By doing this they at least kept them from partnering with companies making lower quality units. Most homes requiring these units (Large luxury homes with "carwash" shower systems) do not have very low flow fixtures and typically do not need to worry about minimum flow rates.

They need to get people to NOT consider tankless water heaters for as long as they can to protect their own interests. Hard water contains particulate that is dissolved in it. Capacities of these water heaters have improved greatly over the first tankless models that showed up about 10 years ago in the US. This is why many gas fired tank water heaters develop leaking tanks and why many of them fail when the bottom of the tank is burned through, flooding the house. I don't think tank heaters will ever completely be replaced with tankless. If you are within 1 GPM of this rate you will be happy. You should look for a model that has a minimum flow rate of .5 GPM for a residential application and one that will operate well down to about 30 PSI system pressure. Some will print more than others will but it is all for the same reason. It is a grouping of conductive wires with sometimes one or more electromagnetic shielding inside/outside.
