The problem with conventional water heaters is that they are centrally located and it often take over a minute for hot water to arrive at the faucet. All you needed was enough hot water to wash your hands or shave – normally less than a quart. In the process several gallons of water are flushed down the drain, and the energy used to heat it is lost in the water lines between the water heater and the faucet. With Aqqua HotStream, you get instant hot water and conserve both water and energy.

Connect the Aqqua HotStream to the cold water supply and you eliminate line losses completely. This is ideal for applications where draws are occasional and relatively small. Bathroom and shop sinks are good examples. Aqqua HotStream delivers more than enough hot water to accomplish the task at hand, and eliminates waste. So does that mean you'll run out of hot water after one gallon? If you just let the tap run, yes. But if you use only what you need, our field tests show that under normal operating conditions, you will always have a ready supply of hot water. It takes a little discipline, but nothing we shouldn't be doing anyway.

For higher draw applications like the kitchen sink, connect Aqqua HotStream to the hot water supply. Hand washing and other low-draw tasks still represent most hot-water use, but on occasion you need to draw enough to fill the sink. So if Aqqua HotStream runs out of hot water, just keep the faucet running, and hot water from the central water heater will arrive soon. In the process, you re-prime the Aqqua HotStream in the process.

Most point of use water heaters use a single tank to store hot water. When the faucet is turned on, cold water from the feed line begins to mix with the hot water, and the delivery temperature begins to drop almost immediately. To compensate an over sized storage tank is typically used and that means higher energy use and more space required.

In contrast, Aqqua HotStream uses a unique and smart design that incorporates water compartmentalization and heat prioritization controlled through a micro-processor to optimize hot water delivery performance and energy efficiency.

Electric tankless water heaters have very high power requirements and are flow-rate limited depending available power. Conventional homes rarely have electric circuits installed in the bathroom or kitchen necessary for these systems and the cost of adding circuits can far out weigh the cost of the water heater itself.

Gas powered tankless heaters are normally located on the side of the building for noise and ventilation purposes. So there is a delay waiting for hot water to arrive at the sink along with wasted water and energy.
