More about this product
WaterBoost HotWash WB-18
The HotWash WB-18 brings genuine hot water to wherever you’re working — no tap, no hosepipe run, no waiting on a tank to warm up. Built for horse owners who need a proper wash-down after exercise or turnout, it pairs an instant gas-fired boiler with a rugged all-terrain trolley, so hot water goes exactly where the job is.
Dial in your temperature and let the digital display confirm it before you start. Running on LPG/propane from an on-demand 36kW boiler, the WB-18 delivers up to 12L/min of steady flow — enough for a quick sluice-down or a full grooming session without losing heat partway through. No mains power needed: ignition runs on 2x D batteries.
The whole system is mounted on a puncture-resistant 10″ tyred trolley rated to 200kg, with a dedicated platform and heavy-duty ratchet strap for a 6L gas bottle (bottle not included). Yard, field, or wash bay — it rolls straight there.
A 10m hose and 9-pattern spray gun give you the reach and control to work all the way around a horse without constant repositioning — everything from a gentle mist to a full jet, on tap.
