What is ETS?

Electric Thermal Storage (ETS) heaters are 100% efficient heating units designed to provide low-cost heat, 24 hours a day. When you choose ETS heat you also get nearly half-price electricity for all of your electricity needs, 14-hours per day in the winter, and 8-hours per day in the summer. Contact the energy experts at San Isabel Electric for a free analysis to see how you can warm up to comfort while slashing your electric bill!

How do I get one?

ETS heating is a low-cost, safe, reliable, comfortable option if you’re tired of the fluctuations in heating fuel costs, or need a more cost- and energy- efficient solution. Electric thermal storage systems are highly versatile, can be sized to heat a room, multiple units, or can be installed to heat a whole house or business. They work well for retrofits, additions, and new construction because they are small in size and easy to install. 


Get rewarded for helping friends and family say yes to ETS!

If not for your heater, on the coldest day of the year when the furnace went out, I don’t know what we would have done. This unit is a life safer. 


Purrfect! My favorite spot! (mmhm sounds) says Azi.


2 are better than one! We have two ETS units…one in the living room and the other in the kitchen. These keep our home warm during the night so we no longer must get up in the middle of the night to keep the wood stove going. Perfect!


Love this heater! To be sure no one thinks the switch is for the hall light, we used our 3-D printer to make a “Frankenstein” switch cover (highlighted). The time-of-day rates that accompany the installation have been a boon for our electric bills.


Our pets enjoy being near the ETS heater while playing in winter.

Early in the morning-before the roosters start to crow my ETS unit is charging and keeping my home not only warm but also clean.

We get warm sitting on our ETS heater when we’re cold! If cats can do it, so can humans…

WAAARM” Even the dogs love it!


No more cold morning slippers!!


We like our heaters so much we just had a 3rd one put in our home. Everyone was so helpful.


How would we describe our ETS you ask? Three words: hardworking, alpha male, jackhammer, merciless, insatiable.

Yes, we love our ETS!


Humpty Dumpty sat on an ETS
Humpty Dumpty did not make a big mess
There was no wall
Nor a great fall
No king’s horses, no king’s men
No need to put Humpty Dumpty back together again!
