      Further, standard gas hot water heaters are very inefficient users of gas (about 55 percent efficiency). When an indirect hot water tank (like the Buderus S120 - literature here ) is paired with a modulating boiler, you have a gas appliance that is going to consume just the amount of gas needed to produce the hot water and at a 95+ percent efficiency.
