About these specsA hot box heats water — it has no pump and produces no pressure of its own, so there is no PSI rating. Some sellers list one; that figure is the coil's maximum working pressure, not output. Pair it with a machine in the 8–10 GPM range. Source: BE Power Equipment model 99012V

What it's for
If you already own a cold water machine you are happy with and you are turning down grease work because of it, this is the cheapest honest path to hot water. The hot box sits inline and heats what your existing pump delivers.
It is rated for 8 to 10 GPM, so pair it with a machine in that range — putting it behind a 4 GPM unit works but you are paying for capacity you cannot use.
Twelve-volt operation means it runs off the truck. Talk to us about plumbing it into your existing rig before you order; the layout matters more than the box does.

From the shop bench
What we see on the bench
- It is a heater, not a pumpThe hot box has no pump and produces no pressure of its own — there is no PSI rating because there is no pump behind it. It heats the water your existing cold machine delivers. Rating it needs a machine in the 8–10 GPM range or you are paying for capacity you cannot use.
- The coil is the part that mattersBecause the box holds water in the coil between uses, a freeze can split the coil without leaking until it is back under load — the reason we pressure test rather than eyeball it. Coil repair covers the failure mode, and what cracks when it freezes lists the coil among the five.
- Plumbing layout decides how well it worksWhere the box sits in the rig matters more than the box itself. Run it through the right reels and the day flows; starve it and nothing heats right. The tank and rig layout guide is worth reading before you mount it.

Questions buyers ask
- Why is there no PSI on this unit?
- It is a heater, not a pump. A hot box takes the water your existing pump delivers and raises its temperature, so there is no pressure rating of its own. Some listings paste a number in; that figure is the coil’s maximum working pressure, not output.
- What does it need to run properly?
- A cold water machine in the 8–10 GPM range and a 12V supply. Below that flow you have a heater you cannot fill. We pipeline it into existing rigs — call and describe your setup and we will tell you if it is the right add-on.
