50 ft Heated Water Hoses: Wattage, Bore and What Doubles Compared With 25 ft

When 50 ft is the right length

Most RV sites are served by 25 or 30 ft. A 50 foot heated water hose earns its price where the spigot stands at the far corner of the site, at a seasonal lot, or between a house spigot and a greenhouse or kennel. Measure along the ground first. If the run is under about 28 ft, the 25 and 30 ft hoses cost less, draw less and leave less hose to lay out.

50 ft pick

Camco 50 ft (22912)

Ad

Camco · Established brand

The 50 ft version of Camco's −20 °F line, for sites where the spigot is far from the inlet.

Why here: It is the 50 ft hose of the line that Camco documents on its own site: 5/8 in bore, −20 °F claim, drinking-water and lead-free statement and a 3-year warranty with receipt.

Best for: Long hook-ups at seasonal sites when you want the same brand and line as the 25 ft Camco hose.

What speaks for it

• 5/8 in inner diameter (camcooutdoors.com)
• Same −20 °F line as parts 22910 and 22911
• Camco's own site lists a 3-year warranty with receipt

What to know first

• No wattage published by Camco; PIRIT and Miller list double the 25 ft draw for their 50 ft hoses
• Instruction sheet not available online
• Costs several times as much as the low-priced 50 ft hoses

50 ft

Must be laid out, never coiled (PIRIT)

Power. Both makers that publish figures list exactly twice the wattage for twice the length. Three amps is still a small load for the 15- or 20-ampere receptacle on a pedestal. A thermostat hose draws it only while heating: PIRIT ties that to air temperatures approaching freezing, Miller to temperatures below 40 °F.

Price. The 50 ft Camco hose costs clearly more than the 25 ft hose of the same line, and both sit in the premium price class. Budget-brand hoses of 50 ft sit in the mid-range price class. The button on each product shows the current price.

Hose on the ground. Fifty feet is a lot of hose to route around steps, tires and a picnic table. PIRIT writes: “Do not leave plugged in while hose is coiled as this can cause the hose to overheat and melt.” Plan a path where the whole hose lies flat and nobody drives over it.

Only the Camco hose is a pick. The REHOSEUP and VEVOR columns are labeled “Seller data only”: their figures come from Amazon listings, and they are shown for comparison, not recommended.

A dash means that neither the maker nor the seller published a figure.

Camco 22912: the 50 ft pick

Camco's own page lists part 22912 as a 50 ft hose with a 5/8 in inner diameter, states “Prevents Freezing Down to -20°”, describes it as certified for drinking water and lead-free, names campers, livestock, agriculture and kennels as uses and gives a warranty of 3 years from date of purchase with receipt. The −20 °F figure is Camco's claim; no test method is named. The page carries cETLus in the product name.

What is missing: wattage, thermostat data and an instruction sheet. The 360 W in the table above belongs to PIRIT and Miller hoses, and it is only a plausible order of magnitude for other brands, not a Camco figure. The hose is in the premium price class. The brand's lines and warranty statements are on the Camco page.

REHOSEUP 50 ft: the mid-range option

This is the 50 ft hose from the brand behind the 30 ft hose on the 25 and 30 ft page. Everything known about it comes from its listing. It is rated to −45 °F according to the seller, with a “self-regulating external thermostat” in the seller's words and no test method named. The listing names RV, camping, chicken coops and garden as uses and promises a “3-year service”. It names no certification body for drinking water, and neither its title nor its description states an inner diameter. No wattage, no manual and no manufacturer website were found.

Its place is between the other two: clearly cheaper than the Camco hose, in the mid-range price class. If the bore matters to you, ask the seller before you order, because the listing leaves it open.

VEVOR 50 ft: the budget choice with a narrower bore

VEVOR is a named brand that also sells through its own website, but we could not open its product page for this model, so the data comes from the listing title: 50 ft, a 1/2 in inner diameter, a built-in thermostat and a −45 °F figure. That rating is the seller's claim without a test method. No certifier is named for drinking water, and no wattage could be confirmed.

The bore is the real difference. A 1/2 in hose carries less water than a 5/8 in hose at the same pressure, and 50 ft of it adds more resistance than 25 ft. No flow figures are stated in the listing, and we did not research any. For a single faucet or a stock tank that fills slowly, that may not matter. For an RV with several taps in use, it can.

Rules for a long run

The longer the hose, the more the hook-up rules matter. These come from the two manufacturers whose instructions we could read:

• GFCI outlet, no extension cord. PIRIT: “Do not use extension cords.” Miller: “no extension cords”. Both require a grounded outlet with GFCI protection. The 2023 National Electrical Code requires GFCI protection for 15- and 20-ampere receptacles in RV site equipment; older parks may differ. A long hose does not make the cord longer, so the plug end has to sit near the outlet.
• Thermostat in open air. PIRIT requires the thermostat to be exposed to ambient temperature, not in a heated or insulated compartment.
• Water in the hose. Miller: “Do not leave plugged in without water.”
• No added insulation unless the maker allows it. Miller: “Do not insulate the hose.”

A long hose also does nothing for the unheated ends. The spigot, regulator and inlet need their own protection; the guide on keeping an RV water hose from freezing shows how. For a garden or kennel run, the heated garden hose page looks at the house-spigot side.

Bottom line

Fifty feet doubles the power draw and raises the price, so buy it only when the tape demands it. The Camco 22912^* (paid link) is our 50 ft pick for its documented bore and warranty. The VEVOR 50 ft hose^* (paid link) costs far less and has a 1/2 in bore according to its listing; like the REHOSEUP hose it rests on seller data only and is not a pick.
