Prefer stainless-steel guards or durable polyethylene covers to resist corrosion and reduce heat loss or accidental contact

Prioritize maintenance for tankless systems

Select flush kits that include a pump, hoses, and descaler solution to simplify routine descaling and prolong heat exchanger life
