I have hard water - is that a problem?

Minerals have less time to settle out of the water column and build up inside the heat exchanger, because tankless water heaters do not store hot water. Another advantage is that the flow of water through the heat exchanger flushes the residue each time hot water is used. Nonetheless water softener can be used with a tankless water heater, and is recommended if you have hard water problems in your home.

Which size should my tankless water heater have?

2007-10-27T05:36:00.000-07:00

You need a model that can deliver the volume of hot water you feel comfortable with. The best method to chose the right size of your water heater is to know how many showers each model can run simultaneously. Some models can run either one or two showers at a time.And don't forget - a tankless water heater can deliver endless hot water, shower after shower.

How can tankless water heaters heat water instantly?

2007-10-25T22:15:00.000-07:00

When you open the faucet of your shower, the flow of the still cold water triggers the heater to turn on. Then the powerful gas burners or electrical elements will turn on, rapidly heating the water as it passes through the vessel. The water is heated instantly, and the time it takes to obtain hot water mainly depends on the distance the hot water has to travel from the water heater to your shower. The burners or elements shut down as soon as you turn off the faucet. You only have to pay for the energy that you used to heat the water for taking this shower.
