Key takeaways
- Distilled water in the source reservoir — every time.
- Wipe the dissolution head after each session.
- Drain and rinse the reservoir weekly.
- Replace the head, filter and hose on the supplier's recommended interval.
Routine care
Before each session: check reservoir level and top up with distilled water if needed. After each session: drain the dissolution head, wipe it dry, and let the unit air for a few minutes before storage.
Cleaning
Weekly: drain the source reservoir, rinse with fresh distilled water, refill. Monthly: remove the dissolution head and rinse the perforations with distilled water. Avoid descalers and acids — they damage internal seals.
Water quality
The single biggest determinant of stack life is what goes into the source reservoir. Distilled or deionised water — no tap, no spring, no filtered tap. Mineral residues coat the PEM membrane and reduce gas output over time.
Replacement parts
Wear items are limited: dissolution head, source-side filter, hose, and occasionally an O-ring kit. Hydrogen Machines stocks all of these for HERO Bath.
Suggested schedule
Daily: distilled water top-up, head wipe-down. Weekly: reservoir drain/rinse. Monthly: head clean, hose inspection. Annually: filter replacement, full external clean, inspect power lead and enclosure seals.
