There are a few possibilities. If the water comes out of the faucet but is cold, then the burner (on a gas unit) or the heating element (on an electrical unit) is not functioning. Check the pilot light. Is it lit? If not, follow the lighting instructions. Is the emergency kill switch (on the wall) in the correct position? Is gas flowing to the unit? Check the valve. For electrical units, did you check the circuit breaker? For either gas or electric units, did you check the position of the thermostat? Perhaps it's improperly set or is defective. Make sure you do not have a washer hose hooked up to your water system while trying to get hot water. The cold water will be infused otherwise.
Check the heating elements in the water heater. These may be bad and need replaced.
Low coolant? Wrong thermostat temperature range? Heater core plugged,restricted or airbound? Water pump not circulating coolant? Temperature control cable not adjusted properly?
usually it is a vacuumn problem right at the heater control switch or sometime under the hood
You haven't said what's wrong with it.
If you are absolutely sure you do not have air trapped in your cooling system then you may have a defective gauge if you are getting heat through your heater. Usually I would say you have a coolant flow problem with either a stuck thermostat or a bad water pump but if you have heat from your heater, then you must have circulating coolant in your system. I would check the gauge or the sensor.
There may be something wrong with your water heater. Try turning up your water heater in your house. If that does not work, you should contact either a plumber or someone who works with furnaces and heaters.
This indicates the inner seal is bad and the water pump must be replaced.
you must be a wierdo.stupid.
Is it water or coolant? If it's water, you probably have a leaky windshield seal. If it's coolant you could have a heater control valve leak.
Absolutely not, I think you have a right, BUT keep it to a limit and know when to stop and walk away from it
It's because "hot-water" is a compound adjective, modifying "heater". It's not for heating water, it's for heating a house with hot water. There are many types of heaters that heat water, but only a hot-water heater is used for providing heated water for domestic use. A hydronic boiler also heats water, but it's only for use in radiators.The name "Hot Water Heater" is completely wrong for any use. There is no need to heat hot water. IT has always been "water heater". The term hot water heater has just been used for years because people don't realize the difference. It has always been WATER HEATER.The first answer is jibberish and makes no practical sense at all.
Try taking the car in for a rad flush. You may have a restriction. Check also that the hoses are not kinked, block heater and rad.
