A New Water Heater Cuts Energy Use by Nearly Half

heater

The firm ISI Technology of South Carolina will soon begin producing a smart water heater, which is designed to cut energy use by 40% over conventional water heaters. They have recently successfully met their funding goal of $125,000 through Kickstarter to begin the production. The Heatworks MODEL 1 compact water heater will measure 12.5 inches by 6.5 inches, meaning that it will fit in most spaces. The water heater will also have Wi-Fi connectivity, so that temperature, power levels and duration can all be monitored and controlled remotely.

According to the description of the heater by ISI Technology it will be 99 % efficient. The heater uses the firm’s patented “direct resistance technology” which takes advantage of the water’s natural resistance to directly heat the water molecules, instead of heating the water with conventional resistance heating elements. The graphite electrodes used in the MODEL 1 heater never get hotter than the surrounding water, which saves energy and allows for exceptional control over the water temperature. The water heater measures water temperature 60 times per second and therefore offers over 500 temperature choices.

The planned Heatworks MODEL 1 is a tankless electric water heater, which is capable of producing instant, endless hot water to a household even at low flow rates. In addition to the energy savings, the heater also provides water savings of about 10%. Since the water heating occurs instantly, the MODEL1 will also eliminate the need to wait around for hot water after each use.

Several units can be installed in a home, depending on its size and hot water needs and each unit can be monitored and controlled individually. So, the water temperature in the kitchen can be set to a higher level than the water temperature in the bathroom. The MODEL 1 heater is also compatible with low-flow faucets and will almost instantly heat the needed water even at flow rates of 0.1 gallons per minute.

The heater can be used to replace the water heater in a home, or hooked up to the existing setup. In other words, the MODEL 1 heater can be placed on the outlet side of your existing gas or electric tank type water heater, which will double the amount of effective hot water the household gets. The MODEL 1 water heater can also be installed anywhere along the hot water piping, even far away from the existing water heater, like, for example in the master bathroom or to heat the water for an outdoor shower. The MODEL 1 one can also easily be used in a solar powered home. Once the production begins, the Heatworks MODEL 1 water heater will retail at $395.

    This sounds like a scam. 40% savings over what. And why would you use one after your water heater. And I’ll buy water savings if it’s installed AT the fixture. But this sounds like BS. Waters natural resistance? To what? Way too many questions. I’m betting this is just an electric water heater in a new package.

      And I quote from the article: “cut energy use by 40% over conventional water heaters…” So that answers one question for you. Replacing a conventional (electric) water heater will save you about 40% on water heating costs.

      The Kickstarter page specifically mentions the 10% water savings if you install AT the fixture, but you don’t even have to go there – it’s in the second graphic in this article.

      This model uses a graphite panel rather than a heating coil. Water is naturally resistant to change in temperature. The large graphite panel allows the water to heat uniformly (with steady distribution due to the water’s resistance to change in temperature) rather than using a small coil (which often heats to extremely high temperatures in cycles providing uneven heating).

      You can get A LOT of additional information on the kickstarter page. This article wasn’t terribly well written, but a lot of your questions are answered a half a page above your comment…

        Any tankless water heater is more efficient than a tanked heater. And making up crap like “direct resistance technology” sounds like hocus locus. And all electric hot water heaters are 100% efficient.

    This is a good idea. But, once you start to add multiple units you are better off running a single bigger capacity tankless water heater. Being it is electric you have to have to multiply the cost of the install by the amount of units you use or a fraction of it. If you do one bigger unit there is only one install cost. Maybe I need to go to the kickstarter page to get this but how many fixtures and at what rate can it handle if by itself. Honestly, who is really gonna add this to their existing system after a hot water heater?
