Hot water problem

I have faced this in my house before a couple of months. then i found a blockage in my pipe-line. I think you should have to watch near your hot water tank.

In another case, you should take from expert advise.

If you have galvanized pipes that are more than 40 years old, they are probably narrowed with rust and/or scale. The hot water lines tend to scale up first, and the narrowing is usually the worst at change-of direction fittings (like elbows and tees at stub-outs). The tank, if it’s more than 10 years old could also be scaled and/or rusted.

An easy problem to fix is clogged faucet strainers and shower heads, but this would not selectively restrict flow in only the hot water to fixtures.

Many times due to blockage it happens. Try to remove blockage if you can or else take plumber help.

Hard water contaminants can build up over time: This can create a layer of sediment on the bottom of the water tank.

It usually happens when there is a blockage in your pipe line. The blockage may be caused by build up of rust, decay or contaminants over the years of using it.

Blockage is the common cause in most of the hot water heater problems. Check the pipes for any kind of blockage near the tank, if its not call in professional plumber for their assistance.

Adjust the thermostat settings and reset. Test and replace the thermostat or high-limit cutoff.

Possible Repairs

    Make sure water heater is not being overtaxed by hot water supply demands. The water heater should have 75% of its capacity as hot water (e.g., a 40 gallon WH should be used for a demand of 30 gallons). To determine required capacity see Calculating Fixture Flow Rates.
    Undo cold water inlet and pipe nipple and remove dip tube. Check condition and replace if required.
    Check for crossed connection by turning off water supply to water heater. Open a hot water faucet. If there is water flow, then their is a crossed connection somewhere. Check for a hot water line connected to a cold water connection on the water heater or appliances such as washer, dishwasher, faucet or shower valves.
    Check for proper flame from burner. A natural gas flame should be a bright blue with the tip of the flame having just a tinge of yellow. A propane flame should have a bluish green flame with a tinge of yellow at the tip.

A blockage in the pipe link could be the main culprit in here. Have you tried to get rid of the blockage in the pipe? if not consider doing it first.

Today’s preferred method of heating a home is with a central heating system. Electric central heating is now the preferred choice of homeowners because it is so efficient, clean and inexpensive.

See it can be the blockage or air in the pipes. Blockage can be because of sediments in the pipes or old galvanised pipes can be the reason for it. Also we use hot waters usually in winters, so it remain off for a while so hot water pipes can have air in them. So these can be the reasons for the reduced pressure.

A minor problem can result into major one when it comes to hot water heater. Hence, get all your electrical appliances regularly serviced and maintained for 24 hours hot water.

Exactly regular repair and maintenance is what always required for efficient working of the hot water system.
