100 ft Heated Water Hoses: Models in Our Selection, the 500-Watt Class and Circuit Load

A 100 ft heated water hose is a farm, garden and seasonal-site product. The PIRIT manual lists 500 watts and 4.5 amps at 120 volts for this length. Our pick is the PIRIT 100 ft hose, because it is the only one of the three whose maker publishes watts, amps and hook-up rules in a manual.

The short version

For a 100 ft run, our pick is the PIRIT 100 ft hose: its manual states 500 W, 4.5 A, a working pressure up to 200 psi and an 18-month warranty. VEVOR and TORVA offer 100 ft hoses known from seller data only; they are shown for comparison, not as picks. All 100 ft must be laid out, never coiled, and plugged into a GFCI outlet without an extension cord (PIRIT). Camco's own site shows no 100 ft hose.

Who needs 100 ft

A 100 foot heated water hose bridges distances that no campground hook-up has: from a yard hydrant to a stock tank, from the house to a greenhouse or a kennel, or across a seasonal lot where the water connection sits at the property line. A 100 ft heated garden hose and a 100 ft heated water hose for an RV are the same product type; the homepage explains the names.

If your run is under about 48 ft, stop here and look at 50 ft heated water hoses. A hose that is twice as long as needed costs more, and all of it has to lie flat.

100 ft pick

PIRIT 100 ft

PIRIT · Brand with a published manual

The 100 ft hose of the brand whose manual states watts, amps and hook-up rules.

Why here: It is the only 100 ft hose in our comparison with a manual that can be read before purchase: 500 W, 4.5 A, working pressure up to 200 psi, 18-month warranty and written rules on cords, GFCI and coiling.

Best for: Farm and garden runs of up to 100 ft when you want the hook-up rules in writing before you buy.

What speaks for it

PIRIT manual lists 500 W and 4.5 A at 120 V for the 100 ft hose
Manual states the rules on cords, GFCI, coiling and thermostat placement
Manual: working pressure up to 200 psi, 18-month warranty
5/8 in hose, thermostat controlled (listing title)

What to know first

The −40 °F figure is from the listing title; the manual names no test method
“Drinking water safe” is stated without a certifying body (manual)
Manual: “Do not use extension cords”
PIRIT's own website did not open on October 11, 2026; the manual was read as a PDF at a dealer

Length: 100 ft
Rating (maker's claim): −40 °F (listing title)
Inner diameter: 5/8 in (listing title)
Heat control: thermostat on the power cord (PIRIT manual)
Watts (maker): 500 W, 4.5 A (PIRIT manual)
Certification named: none; “drinking water safe” per manual

The pick rests on documents, not on a trial; see how we compare. Two limits belong next to it. The −40 °F figure comes from the listing title, and the manual names no test method. And the manual says “Drinking water safe” without naming a certifying body.

The 500-watt class: circuit load

500 W
100 ft hose (PIRIT manual): 4.5 A
Draw at 120 V: 18 months
Warranty (PIRIT manual): 200 psi
Working pressure, up to (PIRIT manual)

Length	Watts	Amps at 120 V	Source
25 ft	180 W	1.5 A	PIRIT manual
50 ft	360 W	3.0 A	PIRIT manual
100 ft	500 W	4.5 A	PIRIT manual

The step from 50 to 100 ft does not double the draw in PIRIT's table: 360 W is listed for 50 ft and 500 W for 100 ft. The manual does not explain the difference, and we do not guess at it.

At 4.5 A the hose alone is a light load for a 15- or 20-ampere circuit. If the same circuit feeds other winter loads, for example in a barn, add them up before you plug in. A thermostat hose draws its rated power only while it heats; PIRIT says the heater will not turn on unless the ambient temperature approaches freezing. The page on power use converts watts into kilowatt-hours and cost at your own electricity price.

Data from manufacturers and listings, checked October 2026. A dash means no figure was published.

Only the PIRIT hose is a pick. The VEVOR and TORVA columns are labeled “Seller data only”: we could read no manual and no maker page for them first-hand, so they are shown for comparison, not recommended. A dash means that neither the maker nor the seller published a figure.

PIRIT 100 ft: the documented pick

PIRIT is the brand of Sykes Hollow Innovations in Manchester Center, Vermont. Its care-and-use manual covers the 100 ft hose with a full electrical rating, a working pressure of up to 200 psi and an 18-month warranty. The listing title adds a 5/8 in hose, thermostat control and −40 °F freeze protection. The manual describes the hose as made for “normal farm and garden use and light commercial use only.”

Its rules are strict and clear: GFCI-protected circuit, no extension cords, thermostat exposed to ambient temperature, never plugged in while coiled, never cut or spliced. PIRIT's own website did not open on October 11, 2026; we read the manual as a PDF hosted by a dealer. Everything about the brand is on the Pirit page.

VEVOR 100 ft: self-regulating, according to the title

The VEVOR hose is described in its title as automatically self-regulating, with a 5/8 in inner diameter, a corrugated protective cover and a 3/4 in GHT adapter. The −45 °F figure is the maker's claim without a named test method, and “lead and BPA free” is stated without a certifier. We could not confirm a wattage first-hand. It is in the premium price class.

A self-regulating cable limits its own heat instead of being switched by a single thermostat. Whether that changes the rule on coiling for this hose is not stated in the data we could read, so the PIRIT warning stays the cautious default: lay it out in full.

TORVA 100 ft: lower end of the 100 ft price range

The TORVA hose sat at the lower end of what 100 ft cost in our October 2026 research. That is still the premium price class: 100 ft of heated hose is never cheap. All data comes from the listing. The title says “NSF Certified, Lead and BPA Free” according to the seller; it names no NSF standard and no certifier we could verify, so treat it as the seller's claim. The title gives a 5/8 in inner diameter. No wattage, no manual and no manufacturer website were found.

Laying out 100 ft

A long hose multiplies the small rules. These come from the PIRIT manual and the Miller Manufacturing help page:

Never coiled while plugged in. PIRIT: “Do not leave plugged in while hose is coiled as this can cause the hose to overheat and melt.” Unused length must be spread out, not looped on a hook.
The outlet must be at the hose, not the other way around. PIRIT: “Do not use extension cords.” Miller: “no extension cords”. PIRIT tells owners to have a qualified electrician install a properly grounded outdoor receptacle, protected from snow and rain, immediately adjacent to where the hose will be used.
GFCI protection. Both makers require it. At RV sites the 2023 National Electrical Code requires it for 15- and 20-ampere receptacles; a barn or an older park may not have it.
Keep animals off the cord. PIRIT: route the supply cord and locate the hose so as to prevent damage by livestock.
Do not bend a frozen hose. PIRIT: first plug in the hose and allow it to warm before uncoiling or bending.
No cutting to length. PIRIT: “Do not attempt to cut or splice hose”.
No added insulation unless the maker allows it. Miller: “Do not insulate the hose.”

What the hose does not heat

PIRIT states that the hose “is NOT designed to provide freeze protection to your water supply.” The yard hydrant, any fittings and the tank at the far end stay at air temperature. Foam covers and pipe wrap for those parts are on the page about insulated water hoses and pipe wrap. Pipe heat cable is made for rigid pipes, not for the hose; see heat tape for a water hose. For house and garden runs, the heated garden hose page has more.

Find your hose in four questions

Hose picker

Question 1 of 4

This selection covers only products sold on Amazon. It is not a market overview. Products are compared by manufacturer and listing data, not by hands-on testing. How we compare

Where will the hose run?

The same hoses are sold for RV, garden and farm use. What changes is the length and what else has to be protected.

Bottom line

For 100 ft, documentation decides. The PIRIT 100 ft hose^* (paid link) is our pick because its manual states the electrical load and the rules. The TORVA hose^* (paid link) costs less, but it is known from seller data only and is not a pick. Before you order either, measure the run again: if 50 ft reaches, 50 ft is the better hose.

Questions people ask

Where can you find a 100 ft heated water hose for an RV?

The 100 ft length comes from PIRIT and from marketplace brands such as VEVOR and TORVA; those are the 100 ft hoses in our selection. Camco's own website showed its heated hoses in 12, 25 and 50 ft that day and no 100 ft model. Measure first: most RV sites need far less, and every foot must be laid out.

How many watts does a 100 ft heated water hose use?

The PIRIT manual lists 500 W and 4.5 A at 120 V for its 100 ft hose. The figure applies to the PIRIT hose only. No wattage is published for the TORVA hose, and none could be confirmed first-hand for the VEVOR hose.

Can you connect two heated hoses together instead of buying a 100 ft hose?

We found no manufacturer statement that allows or forbids coupling two heated hoses. What the PIRIT manual does say: do not attempt to cut or splice hose, and do not use extension cords. Each hose has its own power cord, so two hoses need two GFCI-protected outlets within reach of their cords. Ask the maker of your hoses before you try it.

Will a 100 ft heated hose trip a 15-amp circuit?

By the PIRIT figure the hose draws 4.5 A, well under what a 15-ampere circuit carries. What else runs on the same circuit decides the rest, for example a stock-tank heater in a barn. PIRIT requires a GFCI-protected circuit. If the GFCI trips repeatedly, unplug the hose and have a qualified electrician look at it instead of bypassing the protection.

Can I use a 100 ft heated hose to water livestock?

PIRIT describes its hose as made for normal farm and garden use and light commercial use only, and its listing title names RV, farm and home. The manual adds one farm rule: route the supply cord and locate the hose so as to prevent damage by livestock. The hose keeps the water in the hose liquid; the hydrant and the tank need their own protection.
