COMMERCIAL
APPLICATIONS:
In Commercial applications requiring high temperatures and high volumes of heated water,the capability exists to produce a maximum temperature of 180ºF at 2 gallons per minute or 4.5 gallons per minute at 115ºF RESIDENTIAL: Residential needs are also met where larger volumes are required. For example, the Model 170 can fill a 100 gallon Whirlpool in less than 20 minutes and still supply an endless quantity of hot water for any other household uses. ENERGY SAVING: AquaStar tankless water heaters operate differently than conventional tank type water heaters. Energy savings up to 5001o are realized due to the elimination of the need to store any hot water at all. AquaStar will deliver a continuous flow of hot water at a given temperature within the flow rate specifications (see specification chart). CHOOSING: It is important to choose the right AquaStar model for your application. Tankless water heaters if sized correctly will do the job effectively and efficiently for many years to come. If you need help in choosing the right model or have questions about installation or sizing, ask your local dealer. |
