Faced with installing a new water heater, most homeowners choose a quick like-for-like replacement of their old tank unit or convert to a tankless or heat-pump unit, which often requires infrastructure upgrades and high installation costs. Essency Water Heaters has released its EXR water heater as a more durable and versatile option. The EXR water heater provides 30 years or more of service with its all-polymer storage tank and stainless-steel heat exchanger. The system is a drop-in replacement for a tank—or tankless-style—water heater, installed with conventional fittings and connections by licensed plumbers in an hour or less in many instances. The water heater has a first-hour rating of 80 gallons and can produce enough hot water for nine consecutive showers without losing hot water.
