Water Heater Replacement

Often a water heater repair isn’t your lowest-cost option; a water heater replacement can save you money in the long run. Domestic hot-water (DHW) units typically last anywhere from 8 to 15 years, with those longer lifetimes applying to higher-quality units with longer warranties.  With age, any equipment becomes less efficient and less reliable.
Once your unit has passed its warranty period, it’s time to seriously consider a new water heater installation.  If it’s reached the end of its expected lifetime, has already needed several repairs, or the current repair is expensive, then it’s probably time for a water heater replacement.  If the tank itself is leaking, there’s really no other choice.
You can count on ASAP for professional and objective advice when it comes to sizing and any lower-cost options for meeting the latest energy-efficiency standards.

Types of Water Heaters

The different types can divided up in three different ways:  gas versus electric, standard versus tankless, and residential versus commercial.


Gas water heaters have the lowest operating cost, due to the low cost of natural gas per unit of energy (BTU — British Thermal Units, or therms for short).  Electric water heaters typically cost a bit less to purchase and install but due to the relatively high cost of electricity have higher energy costs to operate.  Modern electric heat-pump units cost far less to operate, but are much more expensive to purchase and install.  As their name suggests, they quite literally pump heat from one place (typically outdoor air) up to a higher temperature.


Standard units have a large tank, usually from 30 to 80 gallons for DHW.   The most common size is 40 gallons.  The burner or electric heating element warms the water in the tank, and that can take a while.  That’s why you may sometimes run out of hot water and have to wait awhile for the tank to heat back up.  Besides gallons of capacity, standard units are rated by their recovery rate, measured in BTU/hour.  Tankless water heaters heat only the water you use, as you use it.  They take up far less space and deliver non-stop hot water.  They also use as much as 30% less energy as there is no tank standing there loosing heat all day and night.  Some units can be mounted right where you need it, say the kitchen or master bath, so you get hot water virtually instantly.  That saves you time and conserves water, since you’re not running the tap waiting for it to get hot.  Tankless water heaters are, however, much more expensive and can take much longer to install, particularly when special gas lines and venting are required.


Residential DHW (domestic hot-water) units are often used in commercial buildings where demands are low.  But commercial equipment is designed and built for more demanding conditions, including a different trade-off between installation cost and operation costs and reliability.  Commercial units may also be double-duty and meet other water heating needs such as for space-heating or process heating.
