Tankless Hot Water Systems

Common Questions and Not-so-common Answers about Tankless Hot Water Systems

Q.  What is a tankless water heater?

A.  Most people currently use a storage tank water heater to provide hot water in their homes. A storage tank water heater keeps water hot 24-hours-a-day, even while you’re at work or sleeping (what a waste!). A tankless water heater, on the other hand, does not store hot water. It heats the water as you use it.

Q.  How can a tankless water heater heat water instantly?

A.  When you open a faucet, the flow of the water triggers the heater to turn on. Whether you use gas or electricity, the powerful gas burners or electrical elements will turn on, rapidly heating the water as it passes through the unit. The water is heated instantly, and the time it takes to obtain hot water is directly related to the distance the hot water has to travel from the water heater to where hot water is being used. The burners or elements then shut down when you shut off the hot water, so the energy that is consumed is only for the hot water that is being used.

Q.  Can it really provide an endless supply of hot water?

A.  Yes. Because storage tank water heaters store a finite amount of water, when that amount is used up your shower goes cold and you have to wait for the heater to heat the water back up (this is known as recovery time). Because a tankless water heater heats the water as it passes through the heater, you can never run out, (provided flow limitations are not exceeded).

Q.  Will one tankless water heater service my entire house?

A.  Yes. You must choose the proper model to suit your home’s hot water needs, which is based upon the maximum flow of hot water you need at any one time (see the Bosch Product Selector to choose the right model for you). We sell tankless water heaters that are capable of handling one shower at a time and others that can sustain a maximum of two showers operating at the same time.

    I am interested in a tankless on-demand water heater. I have a 3 bedroom 2 bath upstairs and 2 bedroom 1 bath downstairs. My 50 gal propane water heater nees to be replaced. Can you tell me what models you have and what they cost. Is there any sale, rebates, tax incentives at this time? Mahalo- Tod Lum
