When to upgrade?

The best time to upgrade your water heater is when it stops working.  However, this can happen fast, so it is best to do a bit of research ahead of time and be prepared if you plan to switch to a heat pump water heater. Complete any required retrofits or upgrades before your water heater fails.

About electric Heat Pump water heaters

Why choose a heat pump water heater?  There is a long list.  First, a heat pump water heater will save most people money.  They are so efficient that they can be less to operate than even conventional tank or tankless gas water heaters (depending on your energy rates).  On average you can save up to nearly $300/year over a conventional electric tank water heater, $130/year over a conventional gas tank water heater and $30/year over a tankless gas water heater.  On top of this there are often rebates and tax incentives.  

Heat pump systems cost a bit more, but will often pay for itself over time (depending on your energy rates).  Installation for a heat pump system can run on average $1,500 or more, compared to a conventional gas tank system which runs on average from $800 to $1,200. The higher cost is due primarily to the higher cost of the unit, which is around $1,100 or more compared to gas units from $500-$600.  There can be additional one time costs for the initial installation if a new electrical outlet is required or the electrical panel requires an upgrade to accommodate the additional electricity load. 

In addition to the energy and cost savings, the climate impact is also significant.  When you install an Electric Heat Pump system you are often converting from gas, propane or oil, which are fossil fuels, to electricity, which we can transition to clean, renewable sources.  If you have an electric water heater now, you will reduce energy use by over 60%.  

If your electricity provider uses mostly coal to generate your electricity currently, your climate savings from switching will not be significant initially.  However, since prices for renewable electricity sources like solar and wind are dropping and many areas have policies to increase renewable energy sources, your impact will be reduced over the lifetime of your water heater.  Better yet, install a heat pump water heater and sign up for a green electricity program and be 100% emissions free with your home water heating right away!  

Finally, since heat pump water heaters have a tank, they have the potential to be an important part of demand response program and can be used in the future to help balance community energy needs.

Choose a new water heater, install and save!

Before you buy a new heat pump water heater, learn a bit more about water heaters, how they work and the important factors in choosing a system with the Energy Star and Consumer Affairs guides.  Consult a professional to help you calculate your savings and figure out which system is best for you.  Choose an experienced contractor and check references and quotes before you choose.  Finally, once you have installed your new system, make sure to maintain it for maximum efficiency, energy savings and comfort!
