For pilot participants. No subscription, and if your tub needs a Wi-Fi module to get online, we'll provide one at no cost.
Estimated savings on a typical tub, about 15–20% of what it costs to keep hot.
To connect, using the app that already runs your tub.
Savings are an estimate from a model of a Colorado tub on time-of-use rates. Yours depend on your tub, its cover and your utility. Pilot results will replace this estimate.
Same warm water. Different hours.
A hot tub doesn't care when it heats, as long as it's hot when you get in. HTTM moves the heating to the hours when power is easy on the grid.
The tub heats in the afternoon and coasts through peak on stored heat, then tops up after 9pm.
Connect the app you already use
Sign in with your tub's own app. If your tub is already online, there's nothing to install.
We learn your peak and your soak
HTTM knows your utility's peak window and when you like to get in, so heat lands at the right time.
The heater rests when it counts
Heating happens ahead of peak. During peak the heater stays off and the tub holds its temperature.
Hot when you want it. Resting when you don't.
Most of the day, nobody is in the tub, but it is still held at soaking temperature. HTTM lets it rest cooler while you're away and brings it back up in time for your soak. You never get into cool water, and the heater does less work.
This resting time is where most of the savings come from.
Nothing changes in the tub except when it heats.
- Ready when you areTell HTTM when you usually soak and the water is hot at that time.
- Cooler when you're awayThe tub rests a few degrees lower between soaks, so you pay to heat it less.
- Works with the tub you haveHTTM connects through the app you already use for your tub.
- Help your local gridLess evening demand means less strain on the lines into your valley.
We're connecting a small group of tubs in the Colorado mountains this winter.
If you own a hot tub you control from your phone, we'd like to hear from you.
