I recently bought a house with a gas water heater and am getting odd
results. Sometimes, i have plenty of hot water, other times, i can
only get luke warm water. It is not due to other sources of water
consuption. The variablity holds true even when the dishwater,
washining maching, etc. has not been in use (first thing in the
morning, for instance). Is this normal for gas water heaters? What
could cause this variable amount of hot water?
