Sizing a Modulating Condensing Boiler - GreenBuildingAdvisor

May 24, 2016 · For the past few decades, an increasingly popular space heating option is a system with a modulating condensing (mod-con) boiler. Because these boilers can potentially have a high efficiency (90-95% or higher), they are often promoted by state and utility subsidy programs. In a well-designed system, the boiler's efficiency can hit or even exceed its nameplate AFUE. But as installed, most

Replacing your Water Heater | Smarter House

Demand or instantaneous water heaters do not have a storage tank. A gas burner or electric element heats water only when there is a demand. Hot water never runs out, but the flow rate (gallons of hot water per minute [gpm]) may be limited. By minimizing standby losses from the tank, energy consumption can be reduced by 10–15%.
