Crystals Forming On Gas Hot Water Heater

I have a Vanguard 6E704 - 30 Gal Gas Water Heater that I have had for a long time but still seems to work fine it produces plenty of hot water for all of my washing and bathing needs.

My question is for sometime I have noticed a Crystalized material (Greenish or Lime in color) forming on the top of the water heater that appears to be originating from the Vent Opening on the top of the water heater.

What might this material be caused from and what is the best solution for removal of the material and cleaning and maintenance on this product.

Thank you in advance for your quick response.

You need a new anode rod in the water heatr. You will probably be looking at a new heater soon.

I have a 640dors reliance capacity40 water won't stay hot long(electric)


remove the two covers one high and one low and set the temp higher. This time of year with colder water comming in the house the water heater has to work harder to raise the temp of the incomming water. In the summer the incommong water is much warmer. 40 gal is a small water heater and you will only get about 15 gal of hot water with the ice cold water entering the water heater as you use the hot water. You can get a bigger water heater. even better is to go tankless and a have never ending hot water and save money at the same time.

Does not have much hot water gets cold fast


tank water heater? if so its because the water is much colder this time of year. water heater has to work harder to heat 40deg. water than 70deg. water in the summer. That also means as you use the hot water from the tank its replaced with very cold water. Causing you to have less hot water. Either get a larger water heater. Or even better go tankless and have never ending hot water and save money at the same time.

Very minimal hot water being produced from my water heater


1) Clean air intake, and do required yearly maintenance.

2) Gas control valve thermostat could be going bad, causing disruption of gas to pilot, and uneven heating of water.

3) Without knowing brand and model number that shows on label on side of tank, it is difficult to add specifics.

I have a Vangaurd 6E720 30 gal electric hot water heater and the water does not get very warm.


If this is a new installation, make sure the unit is feed with at least 208+ volts of electricity.
If it is an older tank, try turning up the temperature setting on both thermostats. Set the top one 10 degrees higher than the bottom. If there is now change in the water temperature after a day or two, replace both thermostats. While your at it, change both element as well. A complete universal electric water heater rebuild kit should only cost around $35.

Old Vanguard Water heater not heating.


the top element is energized until the water in the top of the tank is hot enough to satisfy the upper thermostat, then the thermostat switches and sends power to the lower element. This is done to quicken the recovery time.

We have a new Rheem 30 gal short water heater. It only seems to put out about 10 gallons of hot water before it starts going cold,any suggestions......


I am assuming that everything was fine and then all of the sudden available hot water usage time dropped.

On a dual heating element hot water heater it can be

1. Internal tank loaded with sediment (drain and purge from lower garden hose fitting)

2. Thermostat or element problem with ONE of the 2 heaters. (Trouble shoot element thermostat)

3. Check Circuit breaker for partial trip of the breaker.

Caluclation


This requires a little math....

BTU - amount of heat it takes to raise one pound of water 1 degree F.

I gallon of water = about 8.54 pounds

91 gallons of water = about 777 pounds = 777 pounds x 70 degree rise = 54,390 BTU.

1 Therm (what the gas company measuers in) is 100,000 btus

1 therm costs about $.45 (45 cents) depending on where you are

54,390/100,000 x $.45 = about $.25 per hour

This cost can vary somewhat depending on the inlet water temperature, gas cost, and the efficiency of the hot water heater
