Tankless Water Heater Installation Process

Tankless water heaters may be small, but they do pack a punch.  The installation process is for one of these on-demand heaters remains rather complex.  This is no DIY project.  It requires a licensed professional. That said, as a homeowner, it is always best to be as informed as possible.  It may help to be aware of two major components before speaking with a professional.  These are:

  • Capacity: Know what is to be expected from your tankless water heater(s).  It helps, for example to know the number of showers, washing machines, sinks, showers, and dishwashers your instant hot water heater will serve.  You should also know whether or not you and your family will often be running multiple hot water sources simultaneously.  In other words, think about your needs and goals.
  • Dimensions: An understanding of how much space is available in your home and taking proper measurements is crucial to precise tankless water heater installation.  On-demand tanks are tiny—about the size of a travel suitcase—but even though they aren’t overwhelming in size, exact dimensions make a big difference.   

What the Professionals Consider

To help you be an informed consumer, here is a glimpse at what licensed technicians are concerned with and examining when installing a tankless water heater:

Ventilation

Tankless water heaters require a category three stainless steel exhaust.  This is because stainless steel is effective in preventing corrosion due to condensation.  Stainless steel can be costly, so minimizing run length through strategic placement is recommended.  Backflow dampers and vertical condensate drains help reduce cold air exposure.

Gas Supply

Professional plumbers will check the gas supply line to the meter.  They will calculate the number of BTUs presently used in your home and add to that whatever BTUs the tankless water heater will bring.  The gas company may be brought in if a meter upgrade is necessary, but this is usually free of charge.

Water Quality

A professional will inspect your home’s water quality to determine if you have hard or soft water.  If your home has hard water, a water softener is recommended.  A water softener will break down mineral deposits in hard water to prevent unnecessary corrosion thereby extending the life of your tankless heater.

Electrical Connection

Gas fired tankless water heaters require electricity to operate.  Electricity is used not to heat the water, but to power the heat exchanger when needed.
