Camco −20 or −40 Heated Hose: Part Numbers, Stated Differences and Who Needs the Colder Line
Camco sells two lines of heated hose. The −20 °F line, parts 22910, 22911 and 22912, is on Camco's own website. The −40 °F line, with 22920 and 22922 in its Amazon listing titles, was not found there on October 11, 2026. Besides the number, the listings state two differences: a self-regulating heating cable and a 10 ft power cord instead of 6 ft. Neither rating comes with a test method.

The short version
The Camco −20 °F line (22910, 22911, 22912) is documented on Camco's site and is our recommendation. The −40 °F line (22920, 22922, 22924) rests on listing data: a self-regulating heating cable with a thermostat and a 10 ft cord instead of 6 ft, at a clearly higher price. Both ratings are maker claims without a named test method, so the colder figure is not proof of more protection.
Short verdict
Take the −20 °F line unless one of the two stated differences of the −40 °F line solves a real problem at your site. The −20 °F hoses are the ones Camco documents on its own pages, with bore, drinking-water statement and a 3-year warranty with receipt. The −40 °F hoses cost clearly more, and what is known about them comes from Amazon listings. A colder number on the box is not evidence of a wider safety margin, because no test method stands behind either number.
Camco 25 ft (22911)
AdCamco · Established brand
The 25 ft hose whose listing names its certifications and its certifiers.
Why here: The 25 ft hose of the line Camco documents on its own website. The colder figure of the other line is not backed by a stated test, so the documented hose keeps the recommendation.
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

A dash means that neither Camco nor the listing published a figure.
The differences, point by point
The rating
−20 °F against −40 °F looks like the whole story and is the weakest part of it. Camco's pages say the −20 °F hose “Prevents Freezing Down to -20°”, the other line's titles say “Freeze Protection to -40°F/C”. No page, listing or standard we have seen says under which conditions either figure holds: in what wind, for how long, with standing or flowing water. Two unexplained figures cannot be ranked. The page on heated hose temperature ratings goes into what such numbers can and cannot tell you.
The heating cable
The −20 °F listings describe a thermostat-controlled heating cable: a thermostat switches the cable on in the cold and off again. The −40 °F listings describe a self-regulating heating cable and a thermostat that “only heats as needed”. A self-regulating cable limits its own output as it warms. Camco publishes no technical sheet for either line, so the wording of the listings is all there is. How the two principles work in general is explained under how a heated hose works.
The power cord
This is the most tangible difference. The −20 °F listings state a 6 ft cord, the −40 °F listings a 10 ft cord. Four extra feet can decide whether the plug reaches the outlet at all, and the usual workaround is ruled out by the makers who publish their rules: PIRIT writes “Do not use extension cords”, Miller Manufacturing “no extension cords”. Camco's own instruction sheet is not online. Both lines come with an adapter so that either end of the hose can face the outlet.
Documentation and warranty
For the −20 °F line there are two sources that can be held against each other, Camco's site and the listing, and they disagree on one point: 3 years with receipt on the site, Limited 1 Year in the listing data. For the −40 °F line there is only the listing: “1 year limited” for the 25 ft hose and no term at all for the 12 ft hose. Keep the receipt in every case.
The price
The −40 °F hoses sit clearly above the −20 °F hoses of the same length. We state no dollar figures; the gap was large on the day of our research and prices move.
Take the −20 line or the −40 line?

Who needs the colder line? On the evidence available, nobody can be told that they need it for the temperature. If nights at your site really approach −20 °F, the sound advice is to ask Camco in writing what each figure rests on, and to plan for everything the hose does not heat: the spigot, the regulator, the filter and the RV's own lines get no protection from either hose.

The single models are described under Camco 22911, 25 ft and Camco 22912, 50 ft. The brand overview with the warranty question is on the Camco page. Hoses from other makers with a −40 °F or −45 °F claim are compared on the page about 25 and 30 ft heated hoses, and the heated water hose overview starts with the choice of length.
Questions people ask
What are Camco 22922 and 22924?
They are part numbers of Camco's −40 °F heated hose line. The Amazon listing title of the 25 ft hose carries 22922 and that of the 12 ft hose 22920. For 22924, retailer listings describe a 50 ft hose of the same line; that hose is not in our product data. The −20 °F line uses 22910 for 12 ft, 22911 for 25 ft and 22912 for 50 ft.
Is the Camco −40 hose worth the higher price?
Not for the number alone. Neither line names a test method for its rating, so the figures cannot be compared as measurements. The differences the listings do state are a self-regulating heating cable and a 10 ft power cord instead of 6 ft. If the longer cord decides whether the plug reaches the outlet, that is a concrete reason. Otherwise the −20 °F line is the better documented choice.
Why do the listings say −40 °F/C?
Because −40 is the one point where the two scales meet: −40 °F and −40 °C are the same temperature. The listings of the colder Camco line use that notation. It says nothing about how the figure was established; like the −20 °F of the other line, it is the maker's claim.
Does Camco's website show the −40 °F heated hose?
When we checked on October 11, 2026, camcooutdoors.com showed heated hoses of the −20 °F line in 12, 25 and 50 ft, and we did not find the −40 °F line there. We know the −40 °F hoses only from Amazon listings of the Camco store. Everything stated about the colder line on this page therefore comes from listings, not from Camco's own product pages.
