Why is the water from my Marey 26HW70 A not hot enough?

If your Marey Water Heater isn't producing hot enough water, you can start by checking for cross-plumbing between your cold and hot water lines. Also, verify that the gas supply valve is fully open. Ensure that the gas line is properly sized and that the gas supply pressure is adequate. Finally, check if the set temperature is set too low.
