Why is my heater blowing cold


Most likely it is the heater control valve that shifts air from blowing across your heater core to your air conditioner core.

If your fan works and your car is fairly new..meaning your heater core isn't dirty and full of craap...then it is the climate cotrol valve.
If you are lucky, it might be a thermostat that is bad and blocking hot water from entering your heater core. Bottom line, if hot water doesn't circulate thru that little heater core, you won't get heat.
You might be able to look under the hood and grab the hot water lines that go thru the firewall and feed your heater core. If they feel cold to the touch after engine has warmed up, then you aren't getting circulating water to the heater core. If they feel nice and warm, then the heater core is fine, but your climate control valve has closed off the fan that blows across the core to disperse heat into the cabin

Want to save up to 25% on water heating?


Want to save up to 25 % on water heating? Follow these simple recommendations:

SAVINGS ON HOT WATER HEATING:

1) If you have a tank water heater (electric, gas, or oil-powered), the easiest way to lower your bill is to lower the water temperature. Most usually, a setting of 100-110 F should provide water that is hot enough for pretty much anything. In some water heaters, this corresponds to somewhat below the "MIDDLE" setting.

2) Touch the outside of your water heater tank. If it feels warm, purchase a "water heater blanket" for around $10-$20. It goes around the water heater to help keep the heat inside. Be sure you DO NOT cover the very top vent of the heater (if you have a gas-powered one).

3) If your water tank is more than 15-20 years old and it needs to be replaced, buy one that has at least a 12 year guarantee. In a recent article, Consumer Reports cut open several different brands of water heaters. The ones with a guarantee of 12 or more years had almost TWICE the amount of insulation that the ones that only had a 5 or 9 year guarantee. Also, be sure to get one that has a high efficiency, even if they cost a bit more. You'll save money in the long run.

4) Install a "low flow" showerhead (2.5 gallons per minute or less). You can buy them for as low as $10-20. With a 2.5 gpm showerhead, a 15 min. long shower will only use 37.5 gallons of hot water. Some "ultra low flow" showerheads deliver 1.6 gpm, saving even more.

5) Do not take baths in your bathtub too often. Although bathtubs vary in size, they are usually around 50 gallons, so filling up your bathtub will use 33% more hot water

6) At least once a year, drain the water from your water heater to get rid of any hard water deposits or any solids that may develop inside the tank. To do this, turn off the circuit breaker of the water heater (if you have an electric one) or turn the gas off (if you have a gas one). Wait at least 30 min. to let it cool down a bit. Close the cold water intake to the tank (there should be 2 pipes on top of the tank; the coldest one is the cold water intake). Locate the drain valve, usually on the BOTTOM of the tank. Place a bucket under it and open the valve (BE CAREFUL; VERY HOT WATER WILL COME OUT). Drain all the water. Close the drain valve. Open the cold water valve and allow the tank to fill up all the way (this may take a while). After the tank is full, open the gas valve (if you have a gas water heater) and light up the pilot or turn the circuit breaker on (if you have an electric one).

Water not heating


Dish washers only use water supplied from the hot water side of the pipes under the cabinet or sink, so if you installed the dishwasher yourself, be sure that you ran your inlet water line and connected it to the hot water side, and not the cold water side. The dish washer has heating elements inside the machine to dry the dishes, not heat the water. If this is hooked up correctly and you are still getting cold water to heat the dishes, the problem may be that the unit is too far from the hot water tank. In that case, you may need an auxiliary hot water tank installed near the dishwasher under the cabinet. They make small tanks for such purposes.

Hot water in kitchen only froze


good idea to let the cold water to run a bit to stop freezing up . Pity that you didn't do the same with the hot water. There is only hot water in the tank but the water in the hot water pipes will freeze as the heat goes out of the pipes. (Always to have to wait for the hot water to come through when you use the shower or bath.) The water will freeze up right back to the hot water tank

My water heater heats everything except my lower shower


Let's walk our way thru this one: I assume you have an upstairs shower, and a downstairs shower?-- Are you able to follow the pipes coming out of the Hot Water Heater?-- Can you trace where the pipes to the upstairs shower go?-- And what about the pipes to the lower shower? -- Do they BOTH come off the HOT water pipes coming out of the top of the HW Heater?
A big help in tracing pipes, is by having the hot water run in the Shower that is getting HOT water-- Feel the HOT! pipe?-- Now-- shut that water off, and go to the lower shower-- When it is running, can you hear water flowing out of the pipes at the top of the Hot Water Tanks?-- or do you feel Cold water moving-- Can you travels where it is flowing from? Get back with me, and tell me what you are feeling, and hearing-- Mack B

Were is cold water inlet and hot water outel on model 71-40d b


Cold inlet and hot outlet are marked on top of water heater.
Usually there is a letter or word embossed into the metal top.

If tank is connected, then turn on hot water tap for a few moment and feel which pipe is hot.

Cold water enters bottom of tank through dip tube located on cold side. If hot and cold are reversed, the water heater will not perform as expected.

Water heater supplies about a pint of hot water than turns cold?? what is th eproblem


Hello Rsjohnson164,

I understand that you are having a problem with your hot-water tank not producing any amount of hot-water. I would suggest that you turn off the cold water supply to your hot water tank and drain the tank and see how much water comes out of it.

Flush the tank:
1. Turn off the cold water supply
2. Hook a water hose to the boiler valve (spicket on the bottom of the tank) and turn on the valve
3. Turn on the cold water inlet line and let it run for about 15 minutes or until you get good pressure coming out.

Check the Elements:
1. Turn off the power to the hot-water tank
2. Remove the service panels
3. Remove one wire from the element and use a multi-meter to check continuity
4. If no continuity replace one or both elements

If you do all of this and still have a problem repost to this thread and we will check your thermostats to make sure they are working properly.

Thank you for choosing FIxYa.com

That is normal, the heat just rises from the hot water, the pipe on the right should be cold and if you were to run hot water anywhere in the house it will immediately cool of the cold inlet pipe and you can feel it
