Tankless Water Heaters

Toyotomi water heaters are on-demand, which means there is no costly storage of hot water until it is needed. Like all Toyotomi products they are safe, reliable, and easy to install. You will love the convenienceā€¦and your new lifestyle.

Rinnai Condensing tankless water heaters are compact heating units that provide hot water as it is needed, and do no store hot water like traditional tank–type water heaters. When a hot water tap is turned on, water enters the tankless water heater. A sensor detects the water flow, and activates an electric or gas heating device, which quickly raises the water temperature to a preset level. When water flow stops, the heating element shuts off. Thermostatically–controlled tankless water heaters vary their output temperature according to water flow rate and inlet water temperature.

Enjoy up to 40% energy savings, endless hot water, and significant space savings.

Unlike traditional storage tank water heaters, Rinnai tankless water heaters do not store a reservoir of hotwater. As a result, standby losses are reduced, which makes them an energy–efficient alternative to traditional water heating. When water flow is detected, they begin heating water, making them highly efficient and cost effective. When the demand for water ceases, they shut down and use no energy.

There will always be hot water. Endless hot water – for bathing, cooking, dishes, laundry, and all the other countless ways hot water enriches our lives.

Tankless water heaters consume a fraction of the space consumed by a tank heater. They can be mounted inside or outside.

Because tankless heaters do not store water, they are less subject to corrosion than tank–type heaters. As a result, their expected equipment life is possibly longer – possibly more than 20 years, compared with 10 – 15 years for traditional heaters. Also, because they are not heating 40 – 50 gallons of water 24 hours a day, tankless water heaters are less susceptible to leakage than tank–type water heaters.


Gas, Electric or Oil Tank Water Heaters

The most common way to heat water in the United States is with a tank–style water heater. Tank water heater units heat water even when not in use, to compensate for standby heat loss. Insulation between the storage tank and the outer jacket slows this heat loss, but cannot eliminate it entirely. To maintain a preset water temperature, the water heater must cycle on periodically, even when there is no demand for hot water.

Tank water heaters generally have about 70% usable capacity, meaning a typical 50–gallon tank has about 30–35 gallons of truly hot water in reserve for usage. If there is high demand over a short period – a family taking back–to–back showers in the morning or a vacation home packed with guests – the hot water can run out.

Indirect Water Heaters

Indirect water heaters use a home's space heating system, typically a boiler, to heat water. They're part of what's called integrated or combination water and space heating systems.

A tankless coil water heater provides hot water on demand without a tank. When a hot water faucet is turned on, water is heated as it flows through a heating coil or heat exchanger installed in a main furnace or boiler. Tankless coil water heaters are most efficient during cold months when the heating system is used regularly and can be an inefficient choice for many homes, especially for those in warmer climates.

Indirect water heaters are a more efficient choice for most homes, even though they require a storage tank. An indirect water heater uses the main furnace or boiler to heat a fluid that's circulated through a heat exchanger in the storage tank. The energy stored by the water tank allows the furnace to turn off and on less often, which saves energy. An indirect water heater is used with a high–efficiency boiler and well–insulated tank can be the least expensive means of providing hot water.
