Compact Combination Boiler

Rheem’s Professional Prestige Combination Boiler is the latest innovation in the company’s tankless gas water-heater line-up. At 95% AFUE, the Combi Boiler is Energy Star–rated and provides efficient hydronic heating and continuous hot water even in the coldest climates, says the manufacturer. The high efficiency is a result of the Combi Boiler’s ability to extract more heat from the unit’s exhaust gases, according to Rheem. Its compact design makes it easy to install and ideal for smaller homes or multifamily applications. Pricing ranges from $2,280 to $2,450. rheem.com
