Hot water heaters account for the second-most energy use in a typical household, after your HVAC system, but many homeowners don’t think about the potential energy savings of upgrading their old beat-up storage tank unit.

While replacing your old water heater with a newer gas or electric resistance model will certainly be more energy efficient, more significant savings can often be had by upgrading to a high-efficiency unit. Greencat offers both heat pump water heaters and tankless on-demand water heaters for homes throughout California, including those in Los Angeles, Orange, Western Riverside, and Western San Bernardino Counties.

Heat Pump Water Heaters

Heat pump water heaters pull heat from the surrounding air and use it to warm up the water in your storage tank. Because they aren’t generating heat but simply moving it from one location to another, they are two to three times as efficient as traditional hot water heaters. Heat pump water heaters are about the same size as traditional units, but you’ll notice a big difference when it comes to your water heating costs.

“On Demand” Tankless Water Heaters

Tankless water heaters, on the other hand, are dramatically different from the water heater you likely already have in your home. Unlike other types of water heaters, they don’t have a storage tank where water is heated and kept for future use—when your faucet or shower turns on, the water you need is heated instantly.

One of the biggest issues with storage tank hot water heaters is that the water being stored needs to be constantly reheated to keep it warm for whenever you are ready to use it. Tankless systems, on the other hand, eliminate this source of energy waste altogether. You only heat the water you’re actually going to use, which helps lower your energy bills.

Tankless water heaters come with two other major benefits.


  1. Because water is heated on-demand, there’s no risk of running out of hot water, though if you have a big home, you may want to consider installing multiple units for adequate water flow.

  2. Because there’s no storage tank attached, tankless water heaters take up significantly less space than a traditional unit. This can particularly come in handy if you have a limited area for installation or want to free up space.
