Buying Guide
- Storage vs. instant heat: Decide if you need a small storage tank under the sink or an on-demand system for faster recovery. Smaller tanks save space, while larger capacities reduce frequent refills for higher usage.
- Electrical vs. propane: Electric models are easy to install in a van with a 120V supply. Propane or dual-fuel units offer off-grid capability but require gas hookups and venting considerations.
- Space and mounting: Measure available space for under-sink cabinets, shelves, or wall mounts. Consider floor clearance if you plan a floor-mounted installation.
- Safety features: Look for glass-lined tanks, insulation efficiency, T&P relief valves, overheating protection, and leakage safeguards to protect compact van interiors.
- Heat recovery and efficiency: Higher thermal efficiency and faster recovery reduce wait times, which is important for showers and multiple uses in a row.
- Maintenance: Durable materials (like stainless steel) and easy-access panels help with routine cleaning and inspection in a mobile environment.
