Using your Haygain® hay steamer
Read the safety chapter
Before you use your Haygain® hay steamer, read the Safety chapter on page 4.
After you set up your Haygain® hay steamer and make sure it is safe, you can
start steaming hay.
If you are working in freezing conditions, see page 15.
You can feed steamed hay to your horse immediately or ideally within 24 hours
of steaming.
To steam hay, complete the following tasks in this chapter:
- Fill the steam generator with water.
- Load hay into the hay chest
- Steam hay in the hay chest
- Unload hay from the hay chest
Fill the steam generator with water
Warning: Do not open the cap on the steam generator when the steam
generator is hot. Ensure the steam generator has cooled down.
Do not stand over the steam generator when you unscrew the cap.
Do not pour cold water over a hot heating element.
Warning: Take care not to overfill the steam generator with water. Never add antifreeze or other additives to the water. Additives in the steam generator can be a health hazard to your horse or can damage the steam generator. It will also void the warranty.
Before you can start steaming hay, you need to fill the steam generator with water.
-
Unscrew the cap on the steam generator.
-
To ensure the steam generator is empty, hold it by the handle and tilt it. Empty the water through the filler spout into a drain or container.
-
Place the funnel in the filler spout and carefully pour up to 1 gallon of clean tap water into the steam generator.
To check the water level in the steam generator, you can use the measuring dipstick. -
Remove the funnel from the steam generator, then screw on the cap and tighten it by hand.
Load hay into the hay chest
Warning: Do not block the drain hole in the base of the hay chest. A blocked drain hole may cause damage to the hay chest during the steaming process.
The hay chest can hold just over half a standard-size bale of hay, several hay
nets, or loose hay.
When steaming part of a bale of hay, re-tie it using bailing twine to keep it
together. After steaming, cut and remove any bailing twine.
After steaming, any metal parts on hay nets will be very hot. The hot temperatures in the hay chest can also cause some hay nets to shrink. We recommend you use Haygain® hay nets, which do not have any metal parts and are heat-resistant so will not shrink. You can order Haygain® hay nets from haygain.com
- Lift the lid of the hay chest.
- Check there is no loose hay in the hay chest, and that the steam holes and drain holes are not blocked. If there is any loose hay or blockages, clean the hay chest before you load new hay. Read more about cleaning the hay chest on page 16.
- Place the hay into the hay chest. Place hay nets or wedges of loose hay vertically, so that they are parallel with the sides of the chest.
- Press the hay down firmly, being careful of the manifold spikes. Ensure the manifold spikes fully pierce the hay. Avoid overfilling the hay chest and leave a gap between the hay and hay chest walls.
- Close the lid of the hay chest and fasten the latches.
Steam hay in the hay chest
Do not allow the steam generator to run out of water
If a steam generator runs out of water, also known as “boils dry”, it can be
damaged. If the steam generator boils dry, switch off the steam generator
immediately. Before you unscrew the cap and add more water, allow it to cool
down. Do not stand over the steam generator when you unscrew the cap. Do not
pour cold water over a hot heating element.
Warning: Before you plug the steam generator into a power outlet, mop up any water spillages around your Haygain® hay steamer. Ensure the plug, cable, and power outlet are clean and dry.
When you steam the hay in the hay chest, the internal temperature of the hay
chest can reach 176 °F and above. This represents a temperature of 212 °F in
the hay. The combination of hot temperature and moisture kills the mold spores
and bacteria in the hay, protecting your horse from harmful dust and
microorganisms.
When you are steaming hay, some steam may be observed coming from the back or
sides of the hay chest lid. This is normal and maybe more obvious in low
ambient temperatures. If no steam comes out of the manifold spikes when you
are steaming hay, there can be a blockage in the hay chest, steam generator,
or steam hose. For more information, see page 19.
The power switch on the steam generator has the following three positions:
- OFF
- PREHEAT
- STEAM
The PREHEAT position allows you to continuously heat the water in the steam generator so that it is ready when you need it. For example, on a cold day it can take longer for the steam generator to start producing steam. If you preheat the steam generator, you can do other things while the water heats up. When you are then ready to start steaming hay, turn the power switch to the STEAM position.
-
Plug the steam generator into a power outlet.
-
To switch on the steam generator, turn the power switch clockwise to the STEAM position. The heating indicator light turns amber.
-
Steam the hay for at least 60 minutes then check the thermometer on the hay chest lid.:
• If the temperature shown is at least 176 °F, steaming is complete.
• If the temperature shown is below 176 °F, continue steaming until it is 176 °F. -
To switch off the steam generator, turn the power switch anti-clockwise to the OFF position.
-
Unplug the steam generator from the power outlet.
-
When the steam generator has cooled down, unscrew the cap on the steam generator.
-
Hold the steam generator by the handle and tilt it. Empty the water through the filler spout into a drain or container, to reduce the build-up of limescale.
Unload hay from the hay chest
** Beware of hot steam when you open the hay chest lid When you open the
lid of the hay chest, stand to one side to allow steam to escape. Do not lean
over the hay chest as steam escapes.
Warning:** If the hay in the hay chest is too hot, wear protective gloves
when you handle it. Take care when you unload hay nets, as any metal parts
will be very hot. Do not use sharp objects, for example, hay forks, inside the
hay chest.
After you steam hay, the hay is warm and smells sweet. Most horses love the
taste and prefer it to dry or soaked hay. We recommend you make any changes to
your horse’s diet slowly, to give their digestive system time to adapt. When
you first start using steamed hay, mix it with your horse’s existing hay for a
few days.
The steamed hay may be slightly wet on the outside due to condensation from
the inside of the hay chest lid, however, the inside of the hay will be dry to
the touch.
To ensure the hay chest and its lid always fit together properly, keep the lid
closed on the hay chest as they cool down.
- Lift the lid of the hay chest. Open the lid from the side to allow steam to escape.
- Unload the hay from the hay chest.
- Close the lid of the hay chest.
Working in freezing conditions
**** Do not use anti-freeze products
Do not use anti-freeze or other additives in the steam generator. Additives in
the steam generator can be a health hazard to your horse or can damage the
steam generator. It will also void the warranty.
Warning: Do not open the cap on the steam generator when the steam
generator is hot. Ensure the steam generator has cooled down.
Do not stand over the steam generator when you unscrew the cap. Do not pour
cold water over a hot element.
**** Hot steam and temperatures can cause burns During the steaming process
the steam hose will become hot. Take care when you hold it.
When the ambient temperature is very low, water can freeze in the hay chest,
steam generator or steam hose. In colder ambient temperatures, it will take
longer to bring the temperature up to the level required for steaming. To
reduce steaming time, you can fill a steam generator with hot water before you
switch it on. Please be patient in extraordinary cold circumstances. The
horses are the ultimate beneficiary.

Descaling a steam generator
Label the steam generator when descaling
If you steam hay while the steam generator contains descaler, it can be a
health hazard to your horse. Clearly label the steam generator to say it
contains a descaler to prevent other people from using it.
Warning: Only use a food-grade descaler to avoid any risk to your horse’s
health. Using a vinegar-based solution as a descaler is not advised because it
is not effective enough at removing limescale in the boiler and can cause
problems by only softening but not removing the limescale.
Limescale can build up in the steam generator. To prevent damage to the steam
generator, descale it on a regular basis. The frequency of descaling depends
on how often you steam hay and how hard your local water supply is. Please use
the following guidelines:
Water Hardness (Grains of CaCO3 per Gallon)| Soft or Moderately
Soft (0 – 5.8)| Slightly Hard or Moderately Hard (5.9 — 11.7)|
Hard or Very Hard (over 11.7)
---|---|---|---
Less than one steaming cycle per day| 12-14 weeks| 8-10 weeks| 4-6 weeks
One to two steaming cycles per day| 8-10 weeks| 4-6 weeks| 2-3 weeks
Three or more steaming cycles per day| 4-6 weeks| 2-3 weeks| 1-2 weeks
-
Before you descale the steam generator, clean it. For more information, see page 16. After you clean the steam generator, do not screw on the cap or reconnect the steam
hose to the hay chest. Ensure the steam generator is completely empty. -
Open the packet of descaler and dissolve it in the required volume of warm water, as described in the manufacturer’s instructions.
-
