Key benefits

No More Cold Baths

The Insta-Hot® Original eliminates uncomfortable, cold baths by instantly increasing water temperature up to 40°F warmer at up to 1.4 gallons per minute. You can use your Insta-Hot® to bathe your horses and pets with comfortable warm water, wash your truck and trailer, and even de-ice buckets in the wintertime.

Quick and Convenient Set-up

Set up is quick and hassle-free. Operation is simple. The results are extraordinary.

Simply attach a hose from the incoming water source, start the battery igniter, and hot water will start flowing instantly. Control knobs regulate water temperature and flow. Select a single or double burner for a wider temperature range. The safety tilt switch ensures shutoff if the unit tips from the standard position. Automatic safety shut off after 20 minutes of non-use. Removable drain valve to avoid water pipe and regulator damage caused by freezing.

Small Portable Hot Water Heater – Perfect at Home or on The Road

The Insta-Hot® Original is small and portable. It measures: 12" x 15" x 4" and weighs just 10 lbs.

You can use the Insta-Hot® Original at the barn, by the trailer, at horse shows, and more. Mount the Insta-Hot® temporarily in your wash stall or make it portable with the Easy-Up® Insta-Hot® Cart. By using the Insta-Hot® Cart, you can easily roll the unit right into your trailer, taking up little space in the tack room or wash stall. Don’t forget to grab the Easy-Up® Basket for your cart. This basket will help keep all your bathing needs right at your fingertips.

Heats Efficiently with Extra Safety Features

The louvered vent top keeps the heating unit clean, protected from falling debris, and creates a draft for efficient combustion - more heat, less gas. Use the removable drain valve to avoid water pipe and regulator damage caused by freezing.

The safety tilt switch ensures shutoff if the unit tips from the standard position. Automatic shut off after 20 minutes of non-use.

Insta-Hot® Original Requirements

The Insta-Hot® Original requires a minimum of 20 PSI water pressure to run correctly. The safety tilt feature will not allow the unit to ignite if the unit is not 100% upright. Requires (2) 2 D batteries (not included). The unit should be stored in a dry and protected environment when not in use, drained completely and lines blown out before exposed to freezing temperatures.

You can use any standard ½” or ¾” horse with the unit (larger diameter hoses decrease the pressure more). Any standard hose nozzle can be used, but we recommend a brass twist hose nozzle due to pressure to the unit.

Note: Our units have been tested up to 2,000ft above sea level, and we only recommend using them below 2,000 ft for maximum performance. For every 1,000ft above the recommended 2,000 ft, there will be a 10% decrease in efficiency and performance.

Simple Use With Single Tank Of Propane

Operates off any standard 20 lb. propane tank for up to 18 hours of use. Propane tank not included.

1-Year Limited Warranty

The warranty takes effect on the date of installation of the product, or 30 days after the date of purchase, whichever occurs first, and is effective until the specified anniversary of such date as follows: Item period of coverage: heat exchanger 1 year, all other and included accessories (shower head, hose, regulator, etc. 30 days). Warranty is void if permanently installed or left fully undrained and if pipes freeze and crack. Need replacement parts or repairs? Call EccoTemp at 866-356-1992.

The Insta-Hot® Original is not designed for freezing temps. To avoid cracked pipes, bring your unit inside and drain pipes by making sure the drain valve is open. You will also need to unhook the out-going water line to make sure the water is drained from the heat exchange unit. Insta-Hot® Rapid Freeze Fix can be used to prolong the life of your unit and “fix” cracked pipes temporarily.

Reviews

Insta-hot portable wash

"I have used my insta hot wash system at my campsite At Otter Creek trails. It has been the shower for people and horses all season! It is both easy to use and provides great hot water and pressure. I have been so satisfied with this system! I brought it home to make sure it doesn't freeze so I can use it again next year."

— Carol (5/5)

It Works Great!

"I just recently purchased the Insta-Hot System and have used it a couple of times. So far, I am very pleased with the ease of use and the warmth of the water. My only complaint is that the cart is not very sturdy and the hinges at the bottom do not lock securely causing the cart to fold. I hope I can find a solution so I can stop worrying about it folding up while in use - this is the reason for the 4 stars and not 5."

"Kristen helped me make the purchase of my Insta-Hot seamless and downright pleasant! She was very knowledgeable about the product and made me feel comfortable that my 30 year old horse would appreciate the purchase of this device! We received the items in a timely fashion and she gave ideas on how to make the most of my Insta-Hot. I have used it and it was fabulous!

"This is convenient and can travel anywhere works efficiently and fast. Comes with its own hose. I use on horses, steer,swine and doggies."

— Sammantha F. (5/5)

All in all, it works

"All in all, it works as marketed. Fairly instant hot water with the squeeze of a handle. Flow is nice, though that also depends on the nozzle you use. I will say, this thing has a leak on the inside which I can’t track down. Instructions are fairly limited and explains that you need to use the release valve to drain excess water, but doesn’t say how. The unit does not sit properly on the matching cart. I ordered the cart and had to have 3 replacement sent because of stripped holes and faulty hardware, but that’s a review for another time. I’d say, probably 4 stars if I could figure out this leak. Best bet, if you purchase one, use it ASAP to confirm any issues as mine sat for some time and I’m well past the return/exchange time frame. Hot water baths are nice for the ponies though!"
