Heated RV Water Hose: Choosing Length, Rating and Fittings for the Campground Pedestal

A heated RV water hose keeps the water between the campground spigot and your city-water inlet liquid on nights below 32 °F. Buy the shortest hose that covers the distance, plug it straight into the GFCI outlet on the pedestal and protect the spigot separately, because the hose only heats itself.

The short version

For most RV sites a 25 ft heated water hose is enough. Our pick is the Camco 22911: its listing names an NSF/ANSI 61 certified hose and a CSA lead-free certification. Thermostat hoses of that length draw about 180 watts (PIRIT, Miller). PIRIT and Miller rule out extension cords and require a GFCI outlet. The spigot, regulator, filter and the RV's own lines stay unheated.

What a heated RV water hose does at the pedestal

At a campsite the hose replaces the ordinary drinking-water hose between the spigot and the city-water inlet. A heated water hose for a camper, a heated hose for an RV and a heated drinking water hose are the same product type. The same hoses are also sold for gardens and barns; the homepage sorts out the names and the look-alikes.

One limit comes first, because listings rarely state it. The PIRIT manual says: “This hose is NOT designed to provide freeze protection to your water supply.” The hose heats the water inside the hose. Everything else in the hook-up stays cold.

The hose we recommend for most RV sites

Our pick

Camco 25 ft (22911)

Ad

Camco · Established brand

The 25 ft hose whose listing names its certifications and its certifiers.

Why here: 25 ft covers most hook-ups, and the listing names its drinking-water certifications with the bodies behind them: an NSF/ANSI 61 certified hose and a CSA lead-free certification to NSF/ANSI 372.

Best for: RV sites where the spigot is within 25 ft and named drinking-water certifications matter more than the lowest price.

What speaks for it

  • Listing names an NSF/ANSI 61 certified hose and CSA lead-free certification to NSF/ANSI 372
  • Thermostat-controlled heating cable that only heats as needed (listing)
  • 5/8 in inner diameter
  • Camco's own site lists a 3-year warranty with receipt

What to know first

  • Camco publishes no wattage on its product pages
  • Instruction sheet not available online: cord and insulation rules could not be checked
  • Warranty is given as 1 year in the Amazon listing data and 3 years on camcooutdoors.com
  • Costs clearly more than marketplace hoses of the same length

The recommendation rests on stated data, not on a trial. Nothing on this site was plugged in or measured; the method is on how we compare. The Camco hose also has open points. Camco publishes no wattage, and its instruction sheet is not online, so its own rules on cords and insulation could not be read. The warranty is given as “Limited 1 Year” in the Amazon listing data and as 3 years from date of purchase with receipt on camcooutdoors.com. Keep the receipt and check Camco's current terms.

Length first: measure the run

Length decides price and power draw, so measure before you compare anything else. Run a tape or a rope from the spigot to the inlet along the ground, the way the hose will lie, not through the air.

The margins in the table are our rule of thumb for a hose that reaches without tension; no maker states them. Two manufacturer rules stand behind the advice to buy the shortest length that fits. PIRIT writes: “Do not leave plugged in while hose is coiled as this can cause the hose to overheat and melt.” A hose that is too long has to be laid out in full anyway. And the hose's own power cord has to reach the outlet, because PIRIT and Miller both rule out extension cords. On the Camco 22911 the listing gives a 6 ft cord.

The columns labeled “Seller data only” rest on Amazon listings alone; they are shown for comparison, not as picks.

A dash means that neither the maker nor the seller published a figure. “Seller” and “listing title” mark data that could not be checked against a manufacturer page.

Camco 22911, 25 ft

The 25 ft hose of Camco's −20 °F line is the best-documented choice for the standard run. Camco's own page confirms the 5/8 in inner diameter, the −20 °F claim (“Prevents Freezing Down to -20°”), a drinking-water and lead-free statement and the 3-year warranty with receipt. The listing adds the named certifications and a thermostat-controlled heating cable. It sits in the premium price class. More on the brand, its part numbers and its second line is on the Camco page.

RVGUARD 25 ft

The budget pick is one of the few low-priced hoses whose maker publishes electrical data: a 7 W per foot heating cable and a thermostat that switches on at 47 °F and off at 60 °F, according to RVGUARD. The maker states a −20 °F rating and a 12-month guarantee. It says the inner hose is lead-free and BPA-free but names no certifier. Its page gives no rules on extension cords, GFCI or added insulation.

REHOSEUP 30 ft

Five extra feet solve the common case where the pedestal sits just out of reach of a 25 ft hose. Everything known about this hose comes from its listing. It is rated to −45 °F according to the seller, with no test method named. The listing names no certification body for drinking water and contradicts itself on the warranty: “3-year service” in the text, one year in the warranty field. Treat it as a price alternative in the mid-range class.

Camco 22910, 12 ft, and RVMATE 15 ft

For a spigot within a few feet of the inlet, the 12 ft hose of the same Camco line is our short-run pick: bore and warranty are confirmed on camcooutdoors.com. The RVMATE hose gives 3 ft more reach in the budget price class, and it is rated to −20 °F according to the seller. All of its data comes from the listing title; no manufacturer website was found.

What the temperature rating tells you

Listings carry −20 °F, −40 °F or −45 °F in the title. These figures are maker claims. No listing, manual or standard we reviewed names a test method for them, so a colder number is not evidence of a safer hose. Compare what else the maker states: watts, thermostat switch points, a certifier behind the drinking-water claim, the warranty and the hook-up rules. The comparison by spec sheet lines these up.

Power at the pedestal

25 ft thermostat hose (PIRIT, Miller)

Draw of that hose at 120 V
GFCI
Required by PIRIT and Miller
0
Extension cords allowed by PIRIT and Miller

A heated hose plugs into the 15- or 20-ampere receptacle on the pedestal. The 2023 National Electrical Code, section 551.71(F)(2), requires GFCI protection for the 125-volt, 15- and 20-ampere receptacles in RV site equipment. Older parks may differ. PIRIT and Miller both require a GFCI-protected, grounded outlet in their instructions.

The draw is modest. PIRIT lists 90 W for 12 ft, 180 W for 25 ft and 360 W for 50 ft; RVGUARD states 7 W per foot for its heating cable. A thermostat hose only draws that power while it heats. Camco and the listing-only brands publish no wattage, and we do not estimate one. What the figures mean for a month at a winter site is worked out on the page about power use.

Hooking it up: what the manuals say

Thermostat in open air. PIRIT: “THERMOSTAT MUST BE EXPOSED TO AMBIENT TEMPERATURE”, not in a heated environment or an insulated compartment. Miller: “Keep exposed to outside air, shaded from direct sunlight.” A thermostat tucked into a heated wet bay reads warm air and leaves the hose cold.

No extension cord. PIRIT: “Do not use extension cords.” Miller: “no extension cords”.

Laid out, never coiled. PIRIT warns that a hose left coiled while plugged in can overheat and melt.

No added insulation unless the maker allows it. Miller writes: “Do not insulate the hose.” No Camco statement was found. Insulate the unheated parts instead.

Fittings. RV water hoses use 3/4 in garden hose thread. RVGUARD states that its hose includes a standard 3/4 in GHT adapter. More on threads and the either-end adapter is under heated hose fittings and adapters. Which end carries the cord and thermostat depends on the model, and even the PIRIT manual describes it two ways: one step puts the cord near the female end that goes onto the faucet, another notice puts it at the male, water-out end. Follow the sheet in the box, and keep the thermostat in open outside air wherever it ends up.

The parts the hose does not heat

The spigot and its riser, the pressure regulator, an inline filter, the fittings and the inlet stay at air temperature. These are the places where a hook-up freezes even though the hose works. The step-by-step guide on how to keep an RV water hose from freezing covers them, and insulated water hoses and pipe wrap shows which insulation belongs on which part. Pipe heat cable is not a shortcut for the hose itself: see heat tape for a water hose.

Common mistakes

  • Buying length as a reserve. Extra hose must still be laid out straight.
  • Reading the rating as a test result. It is the maker's claim.
  • Assuming the hose covers the whole water supply. PIRIT says it does not.
  • Leaving a dry hose plugged in. Miller: “Do not leave plugged in without water.” Whether a filled hose can stay on all winter is answered under can you leave a heated hose plugged in.

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

Measure the run, then pick by documentation. For up to 25 ft the Camco 22911* (paid link) states the most about its drinking-water certifications. The RVGUARD 25 ft hose* (paid link) is the lower-priced alternative with published watts and switch points. Whichever hose you choose: GFCI outlet, no extension cord, thermostat in open air, and separate protection for the spigot.

Questions people ask

What length of heated water hose do I need for an RV?

Measure from the campground spigot to the city-water inlet along the path the hose will lie, then buy the shortest hose that covers it. 25 ft fits most sites, 12 or 15 ft fits a pedestal right next to the inlet, and 50 ft is for spigots at the far end of the site. Do not buy extra length as a reserve: the PIRIT manual warns against leaving a plugged-in hose coiled, because it can overheat and melt.

Will a heated hose overload a 30-amp RV site?

The hose itself is a small load. The PIRIT manual lists 0.75 A for a 12 ft hose, 1.5 A for 25 ft, 3.0 A for 50 ft and 4.5 A for 100 ft at 120 V. Miller Manufacturing gives 1.5 A and 3 A for its 25 and 50 ft hoses. The hose plugs into the separate 15- or 20-ampere receptacle of the pedestal, not into the RV. Camco publishes no figure for its hoses.

Are heated RV water hoses safe for drinking water?

That depends on what the maker puts in writing. Camco's listing names an NSF/ANSI 61 certified hose and a CSA lead-free certification to NSF/ANSI 372. Many marketplace listings say lead-free or BPA-free without naming who checked it. The two standards cover different things: NSF/ANSI/CAN 61 is about what a product leaches into water, NSF/ANSI/CAN 372 about lead content.

Does a heated water hose keep the campground spigot from freezing?

No. The hose keeps the water inside the hose liquid and nothing else. The PIRIT manual states that the hose is NOT designed to provide freeze protection to the water supply. The spigot and its riser, the pressure regulator, a filter, the fittings and the water lines inside the RV stay unheated and need their own protection.

Can I plug a heated RV hose into an extension cord if the pedestal is too far away?

The two manufacturers whose instructions could be read say no. PIRIT writes: Do not use extension cords. Miller Manufacturing writes: no extension cords. Both require a grounded outlet with GFCI protection. Choose the hose so that its own power cord reaches the outlet, check the instruction sheet of your model and ask a qualified electrician if no suitable outlet is within reach.
