Tankless Water Heaters: A Hot and Cold Issue

Posted on Tuesday, March 22nd, 2011 at 1:14pm.

293_120We recently installed a tankless hot water heater on our home in Denver's Chaffee Park neighborhood, and although we love it's hot water capabilities, compact size and about $70/year in energy savings, I'm not convinced it's the right decision for everyone.
Let me explain a bit more. A tankless water heater differs from a storage type because it doesn't hold hot water, rather when someone requires hot water high powered burners heat it on demand.
Although you'll never run out (think start the dishwasher, run a load of laundry and then take a well deserved hot bath), these type of water heaters can cost around $1000, and about the same to install because they require special venting and electrical changes; whereas a higher end replacement storage type may cost $450 and only $300 to install.
Even 20 years of energy savings is barely enough to recoup a higher initial investment. My recommendation for cost effective water heating?  When replacing, simply replace with a 9-12 year warranty storage type water heater. These typically have more insulation, bigger burners and better working parts, then set it as low as you can comfortably handle.

These types of unpredictable rate increases from Xcel will more then likely help you recoup your investment more quickly as the price of gas keeps climbing. (Take into account that your $70 energy savings would be compounding and the payback is even quicker). After I installed a solar electric system on my home, my electric consumption dropped by 50% just from being more aware of my daily usage! I imagine the circumstances will be similar with your tankless hot water heater - your hot water consumption will most likely be reduced as you will become more aware of your daily usage. You may notice your showers being shorter, you wash your clothes in cold mode, you fill up the sink to clean dishes instead of letting the water run etc. Also the peace of mind of knowing you are not spewing as much CO2 into the atmosphere to heat your H20 is an added bonus! I think you made the right choice going tankless!
