Quick basic advice on a dripping gas 40-gal hot-water heater
the energy guide labels on appliances arent really to determine exact
operating costs/
their real value is in comparing efficenies in a general way.
obviously a home with 8 kids will use a lot more hot water than a
single guy living alone.
with so many variables, incoming water temp, desired water temp,
amount of water used, cost of gas, etc etc,.
everything is a estimate
