On-Demand Water Heaters

Tank-less, On Demand Hot Water Heaters

  • Tired of running out of hot water?
  • Is it time to replace you old water heater and you want to save money?
  • Wish your house was “greener” and wasted fewer resources?
  • Do you hate having to heat hot water while you’re not home?

On-Demand Saves Energy

A tank-less  “on demand” hot water heater can be a great solution to your residential hot water needs.

These types of hot water heaters do not store hot water, but rather create it on demand. There is no storage tank or the subsequent wasted heat loss from the storage tanks.

What is an On-Demand Water Heater?

Tank-less Water Heaters are an energy efficient way to heat water but are costly to install.

On-Demand systems take up little space and provide a continuous supply of hot water from an energy-efficient and space-saving self-contained high-powered burners.

I like this option because you’re not wasting energy, fuel or money on heated water while you’re sleeping, at work or away on vacation.

Installing one of these units is “GREEN,” will reduce energy expenses and also can qualify you for a federal energy tax credit!

I have a RINNAI brand on demand heater in my house and properly used these heaters are great.

Improperly used they are disappointing and expensive.

Size Unit Properly

To avoid disappointment, make sure to size the unit correctly for your house water usage. The size and number of whole house tank-less water heaters you need will be largely driven by flow rate and that is determined by the number and types of fixtures you may have running at one time. My unit can only handle one shower and one faucet or the dishwasher at one time.

These units are expensive to buy compared to conventional water heater tanks but they come with a tax credit and pay for themselves in the long run!
