The Conservator 90™ Series gas-fired water boiler has features that appeal to both contractors and homeowners, says the manufacturer. It features an AFUE of 90%. Key to this efficiency is the unit’s cast aluminum heat exchanger, which transfers heat three times faster than conventional cast iron, the company says. This means the boiler provides warmth quickly. Its low-temperature supply and return water make it suitable for radiant systems without the need for mixing devices, says the company, and its lighter weight compared to standard water boilers helps ease installation.
