What We Offer for Tankless Water Heaters in Newark

- Cast iron waste stacks, older sewer laterals and galvanized supply risers are common in the pre-war building stock.
- The Ironbound's restaurant density means grease-loaded kitchen drains and kitchen make-up air are steady commercial work.
- Commercial and industrial buildings across the city rely on rooftop units, make-up air and unit heaters rather than residential-style equipment.
