Two Solutions To Eliminate Waiting For Hot Water

1. Tankless Water Heaters

2. On-Demand Water Recirculator

It’s a common problem in DFW, waiting for a hot water to reach a faucet while wasting gallons of water.   Water lines are run under the home.   When it’s cold during winter, the water pipes get much colder than during summer.  This causes the wait for hot water to become longer, due to having to heat the pipe before it can deliver hot water.

The larger the home, the larger the problem becomes.  It’s common for larger homes to have 2 or more water heaters.  This cuts down the wait, but comes at the expense of running two water heaters.  Plus, it does nothing to eliminate the wasted water.  A estimate of wasted water is up to 12,000 gallons for an average family.

The Two Possible Solutions 

  • Tankless Water Heaters are better suited to a home that’s under construction.
  • Hot Water Recirculating System works best for existing homes.  We provide more detail into why each system is better suited within this article.

 

Tankless Water HeatersOn-Demand Hot Water Recirculating System

Hot Water Recirculating systems are not the same as Tankless Water Heaters.  A tankless water heater heats up quite quickly, taking only a couple seconds to deliver hot water.  Recirculating hot water pumps send cold water within the water pipes back into the water heater, and bring hot water to all the fixtures (on that plumbing line) within a few seconds.

Because tankless water heaters only run when needed, they will last about twice as long as a tank water heater.   Tank water heaters last 7-12 years, and their lifespan is dependent on how they are maintained (annual flushing) and how “hard” the water is (how much lime is in the water).   Tankless water heaters require either gas or a dedicated electrical run to them.   The 110 volt units cannot be plugged into an existing outlet.  They draw too much power and will trip the breaker, so they require a dedicated electrical line.  Larger tankless water heaters may require a dedicated 220 volt line.

Bringing gas or a dedicated electrical line to a tankless water heater in an existing home is expensive   The cost for the tankless water heater + its installation may exceed any savings over the life of the unit.  Adding a Hot Water Recirculation System is less expensive to buy & install, and it uses the existing tank water heater.   Plus, it does not require a dedicated electrical line.

There Are 2 Types Of Hot Water Recirculating Systems:

  • Continuous
  • On Demand

Continuous systems eliminate any waiting for hot water.  But, they do this at the expense of bringing hot water to fixtures 24 /7.

On Demand systems nearly eliminate waiting for hot water, delivering it in a few seconds.  You push a button to activate the system.  Once hot water reaches that fixture, the system shuts off.  This eliminates the cost of having hot water at all the fixtures all the time.  Either system eliminates 12,000 gallons of wasted water each year for an average family.

There is a small pump that attaches to the hot & cold water lines at the farthest fixture (from the water heater) in the home.  When activated, the cold water that is typically wasted is recirculated back to the water heater through the cold water line.  Once hot water arrives at the faucet, a heat sensor shuts the recirculating pump off. 

NOTE: Different Systems Have Different Plumbing Requirements.  For an existing home, choose a system that reroutes the water through existing plumbing lines.  Some systems require additional plumbing, in the form of a dedicated water return line.  These are quite expensive to install in an existing home.  It’s likely that type of system’s purchase & installation costs would negate any savings during the lifetime of the pump.
