Redlands water heater work splits between historic-home retrofits and modern tract replacements. Downtown Redlands and Historic Citrus District homes (1880s-1940s) often have atypical water heater installations — basement or crawlspace tanks with original gas line routing through plaster-and-lath construction, occasional original gravity-fed systems converted to forced gas, and heritage-preservation considerations on equipment placement. Tankless conversions in historic homes can be complicated by venting routing and gas line tracing. East Highlands and South Redlands master-planned communities (post-2000) run cleaner replacement work — 10-year-mark proactive replacements with appropriate venting and gas line already in place.
