what would cause different water temps in different parts of the house?

Question

The water heater is shot and bing replaced will that solve the problem?

Answer 1

Replacing the water heater should solve the problem, but I think the different temperatures would probably have to do with valves, or maybe even something blocking the pipe. In the places where the water is cooler, the hot water valves may not be opening all the way.

When you get your new water heater, check and see if it's still doing it. If it is, you probably need to replace at least part of your pipe system.

Answer 2

In a large house, the hot water supply loses heat through the pipes on the way to the various fixtures. Make sure you have foam insulation on the pipe going into the hot water heater (the supply line) and coming out. You really only need a few feet on either side...that will help with preserving some heat to the furthest taps. Replacing the water heater itself will help a great deal.

People with big houses often have "booster" heaters in the line to help keep the hot hot.

Answer 3

yes distance from the heater is a factor insulating the pipes will help also if the temp is colder in the shower you might have a scald proof shower/bath valve see if the sink is the same temp as the shower if not you can adjust the scald limits on the valve you will need the make/model and look on line to see how to do that...

Answer 4

Different diameter pipes causes temp variation. When water flows from lower diameter pipe to higher diameter pipe the temperature is dropped ; as pressure is dropped .Pressure is proportional to temperature . Water heater can not help to rectify this as the question is related to flow of liquid .

Answer 5

That will make the water coming out of the hot tap hotter.

Answer 6

Be sure all the hot water pipes are insulated
