Garden hoses are made from PVC, which has a range of melting points ranging from 100 degrees Celcius all the way up to 260 degrees depending on the additives.
Generally using a garden hose in freezing temperatures isn't recommended as the water can freeze inside the hose, causing it to expand and potentially crack. If you own the GOODLAND Everlasting Garden Hose, temperatures below 32° F or 0° C aren't an issue and won't damage the hose.
Stainless flex hoses have a melting point of approximately 1400-1450 degrees (C). Therefore, they are quite resistant to possible fire. The outer coatings (sleeving) do not have any fire retardant properties.
It's illegal to use a flexible hose outdoors and especially on a hot water heater. You cpuld do it yourself, but i wpuld suggest you call a plumber and have them replace it with copper. A flexible hose will not last in those conditions, hence why it is leaking.
Wrap the Hose in Heat Tape
If you have no professional demands, or if you don't think that buying a heated hose is necessary, you can DIY your hose's heating system using heat tape. Wrapping the heat tape around your hose ensures that everything that is meant to be warm will stay warm.
Use a Heating Cable
A cheaper alternative to purchasing a heated hose is purchasing a heated cable, wrapping it along the length of your current garden hose, and securing it with heat tape. A heat cable allows you to create a DIY heated hose that can protect your hose throughout the winter.
Electrical tape can be used on heat-sensitive applications, provided that the temperature does not exceed 200°F (93°C).
The water temperature can be up to 60°C for short periods. In continuous use, however, the water temperature should not exceed 35°C.
Best Garden Hose for Hot Water
The MAXLite™ 50' 5/8" Hot Water Rubber+™ Hose was made for those jobs that require the use of hot water. This hot water rubber hose features Hose Armour patented technology that will keep your hose from kinking near the spigot.
“Most adults will suffer third-degree burns if exposed to 150-degree water for just two seconds,” reports the U.S. Consumer Product Safety Commission (CPSC). The water in your garden hose can far exceed the temperature the CPSC warns the public about.
Temperature Range: -40°C (-40°F) to 165°C (329°F) Working Pressure: 150 psi for water, 90 psi for saturated steam to 165°C.
Pure water transitions between the solid and liquid states at 32°F (0°C) at sea level. This temperature is referred to as the melting point when rising temperatures are causing ice to melt and change state from a solid to a liquid (water).
To avoid a leaking garden hose you should turn off your hose after each use. Coil your hose up and keep it out of the sun whenever possible.
Most hydraulic hoses operate safely within a temperature range of -40°F (-40°C) to +212°F (+100°C), with specialty hoses extending this range to -40°F (-40°C) to +300°F (+149°C). Exceeding these limits can significantly shorten hose lifespan.
Typically, a good-quality garden hose can last anywhere from 5 to 10 years.
Flexible hot potable water discharge hose with tube according to FDA, ozone resistant. Temperature: from -30 °C (-22 °F) to +110 °C (+230 °F).
Much like the water we swim in, the cold or hot water from a garden hose is not designed for human consumption. A recent study from the Ecology Center in Ann Arbor, M.I., reported that garden hoses can be loaded with hazardous toxic materials.
Silicone offers some of the highest temperature ranges in addition to features like superior tensile strength, elongation, and compression set.
The recommended maximum continuous operational temperature for PVC-U pipes is 60°C. This limitation refers to the complete pipe wall being at 60°C and would apply for continuous flow of a fluid at 60°C.
The cheap way is just add a hot line right beside the existing cold line. Use exactly the same pipe and fittings, buy a red handle instead of a blue one. Get a washing machine Y-hose to mix hot and cold.
The risk of burns is greatest when water temperature is above 120 degrees. 150-degree water scalds in less than a second. 140-degree water scalds in just one second. It takes four minutes for 120-degree water to scald.
Extra-strong and extra-durable, it's perfect for permanent outdoor repairs. This tough tape is 100% waterproof and works in hot & cold temperatures – holding strong in rain, snow, sun, and extreme weather conditions.
Is electrical tape heat resistant? Most electrical tapes regardless of the material are able to withstand temperatures up to 176 degrees Fahrenheit. To be considered electrical tape, the tape must have nonflammable and heat resistant properties.
