Water Requirements
Average UK van lifer uses 10-20 litres daily: drinking/cooking (3L), washing (5L), toilet (2L), cleaning (5L). Larger tanks needed for wild camping; smaller OK for campsite-hopping.
Tank Options
- Underfloor Tanks - Maximise interior space, but reduce ground clearance. 40-80L typical.
- Interior Tanks - Under-seat or wardrobe installation. Easier access for cleaning. 20-50L typical.
- Jerry Cans - Portable backup, use for fresh water only. 10-20L each.
Pump Systems
12V submersible pump (£20-£40): inline with tap, activates on demand. Shurflo pump (£60-£100): more powerful, quieter, professional choice. Consider: pump noise level in small spaces.
Water Heating
- Truma Combi - Diesel-fired, heats water and air. £1,500-£2,000. Most popular UK option.
- Immersion Heater - 240V hookup required. £100-£200. Good for campsites.
- Solar Thermal - UK rarely effective enough for year-round use.
UK Grey Water Rules
Never dispose of grey water in wild spots. Collect in separate tank for campsite disposal. Avoid biodegradable soaps near water sources. Scottish waterways have strict pollution laws.
