You should bleed off any residual pressure by opening hot water on kitchen / restroom faucets. You can also drain tank down using drain valve on the lower portion of the water heater. Please make sure the electricity or gas is also off depending on what type of water heater you have. You do not want the water heater to start heating with an empty tank.

SOURCE: No water flow from hot water tap with a rinnai tankless water hea

Its A Possibility The Left Over Water In The Hot Is Frozen. If Your Line Is Exposed Outside Somewhere It Can Easily Freeze Up. Turn On The Hot Water Everywhere In The House And If Accessible Check The Lines To See Where The Warmth Ends. You Can Leave One Off Over Night In Hopes That It Will Eventually Defrost.

SOURCE: low pressure on hot water taps and showers

Many states building codes require a pressure regulator and expansion tank for hot water heater installation. Check the pressure regulator if you have one as this would only affect the hot water pressure. Adjust or replace. Rap the expansion tank like knocking hard on a door. Hollow sound is good. Dull thud means it needs to be replaced as it is filled with water.

SOURCE: hot water tap only warm water in bathroom but hot in kitchen

Usually when you are having a problem at only one fixture, and not any others it is a sign that you have a faulty fixture. Hope this helps.

Hot water immersion tank. Electric Now there is chugging on coldfill after I turned off mains supply and ran hot water taps to drain off supply to fix a tap


If you turned the electric off before draining, Air gets into the system. It will sound funny untill all the trapped air gets "washed" out of the system. If the electric was left on when refilled, you may have a steam generating situation, causing the chugging.

Had burst pipe, used geyser water to bath kid. Water supply now restored but geyser switch in box keeps on tripping... Help!


Use hair dryer and see if you can dry out parts.
Often, when electronics get wet, they cannot be repaired... like dropping cell phone in bucket of water.

Junkers gas geysers not heating water much


between 60 and 75 degrees c as any hotter will scald you. Have the gas specialist check it out as it may not be getting enough gas flow to the burner either a badly adjusted regulator or a blockage in the gas tap or line.. You control the temp by the amount of water coming out of the tap as you found out when you attempted to restrict the water flow.

Hi i have installed a few bosch gas geysers at our lodge in mozambique.The problem is that the water gets hot when we turn the water on then the heat just shuts off and the water gets cold after a short...


The problem with all that type of water heater is that once the hot tap is turned on sufficient flow must be maintained through the water heater to keep the main gas burner alight. If the heat adjuster is turned up to high, then the person using the hot water will turn it down to a low rate which means the main burner will turn off and result in cold water. Try setting the heat control to the lowest setting that still gives hot enough water. If you have a thermometer adjust control for a temperature of around 50 to 55 degrees Celcius. You may have to fiddle with fine adjustments to get the temperature and flow rates to maintain a constant output of hot water. You may still have intermittent problems. If the heater only supplies baths or showers you could set the temperatuer even lower (45 to 50) to ensure that the hot tap is used more than the cold which will maintain flow and therefore heat.

Sounds like the by-pass valve diaphragm. This valve detects that hot water is being drawn off at the tap and then diverts the mains input water across the heat exchanger. Very often it's the diaphragm inside the valve which is punctured or split.This can be replaced [depending on model] if you take apart the valve
. Remove the front panel and lower the control panel.The valve is at the bottom left of the boiler
Suggest turning off the service taps to the two heating pipes and the cold mains inlet pipes before tackling the valve
