Natural Draft Med Efficiency tanks
New high performance atmospheric vent gas water heaters are specially designed to prevent the ignition of flammable vapors such as aerosol sprays, cleaning solvents, gasoline, paints, paint thinner, and thinner lacquer, outside of the water heater. They are available in 30, 40, 50 and 60 US gallon capacities for both natural and propane gas and feature 45% to 65% energy efficiency.
Power Vented High Efficiency Tanks
Power vent models are superior, quiet water heaters that supply ultimate satisfaction with abundant hot water, quiet operation, reliability and performance. Manufactured for use in a variety of applications, including combo-heating and feature upto 70% energy efficiency.
Tankless, instantaneous, on-demand hot water heat has never been more popular. And why shouldn’t it be? With energy efficiency in the 80-85% range your return on investment is fast and easy! Tankless heaters only heat the water when you turn a tap on, they’re almost silent running, and CO2 emissions are reduced by 900-1000 pounds per year per average household installation! Time to replace your water heater?
Navien makes a tankless system that is 98% efficient by employing the dual heat exchanger condensing system. Its high efficiency is reached by allowing the relatively warm exhaust gases to transfer otherwise wasted heat to the incoming water. This tankless is effectively preheating incoming water before it flows through the primary heat exchanger. This adds about a 10 to 15 percent efficiency increase over a mid-efficient tankless water heater
