What the AI looks for in Hot Water Bottles
- Safety standard
- In the UK, look for bottles made to BS 1970, the British hot water bottle standard. It covers wall strength, stopper seal and leak testing.
- Date mark and replacement
- Check the date mark (often a flower dial) and replace the bottle after about two years or at any sign of perishing. Rubber degrades over time, and old bottles can split and scald.
- Water temperature and fill
- Use hot water, never boiling, and fill about two-thirds. Expel the air before sealing. Boiling water weakens the rubber and raises scald risk. Overfilling strains the seal.
- Cover
- Always use a fabric or knitted cover. Bare rubber against skin can cause burns.
Brands that matter
- Fashy: German maker of rubber and thermoplastic bottles with covers.
- Hugo Frosch: German maker of hot water bottles, including covered styles.
What to avoid
- Filling with boiling water
- Keeping a bottle past its replacement age or with cracks
- Using without a cover
- Unbranded bottles with weak stoppers
Questions
