Shut off hydro/breaker (110VAC) to water heater element. Remove nuts on cover at back side of tank, where you see hydro cable entering. Carefully pull metal, or plastic cover off to expose wiring, element, thermostat,ECO,etc. Double check , no hydro power present with Multimeter, or circuit tester. When your 100% sure no hydro (110VAC) to it, take a close look at all the connectors on little rounds discs, (thermostat and ECO) and make sure they are on good, and making good connections. Once that's checked, and making sure no bare wires are touching studs for cover, or any wires are touching each other, Turn 110VAC breaker back on and Very carefully attach or touch your ground on multimeter or tester to copper wire for hydro, and your positive to screw at element that has the black (hot) wire attached to it. You should read 110-120VAC. If yes, shut off hydro again, and replace element. If no, leave ground where it is, and carefully test voltage at each terminal of the thermostat, and ECO discs. You Should get 110-120VAC at each, if not, the one with voltage in, but not out is defective, and should be replaced, after shutting power off obviously. This is assuming yours doesn't have a thermostat, with a push-in type reset that may have tripped, so look for that as well. Also, some thermostats, or ECO's will have a small pin in the center between the 2 spade connectors that is a reset as well, so if you have those type, push in on those to check for reset as well. When/if you do have that style, shut power off, while resetting to avoid chance of shock. Keep me posted please.

Does the water heater and furnance run on gas and electric?

If the units are in a RV then yes, they both may run on gas and DC (battery power). The furnace requires gas to provide heat and DC power to run the fan. A water heater may be gas or electric, but if gas, it requires gas to heat and DC power to ignite. If the water heater is electric it requires AC power to heat.

Should ele and gas work to gether onwater heate .dont now if we used water or gas.or bouth

Some RV water heaters are both gas and electric, depending on what hookup is available at campground.
Otherwise, water heaters are electric or gas.

Gas water heaters have a 3" to 4" round vent pipe located on top.
Electric water heaters have electric wire connected on top or side of heater, but no vent pipe.

I can not get my heater to work. My gas is working because my range lights and my water heater is working.

Make sure the electricity is turned on, most new units have an electrical ignitor which must be turned on and heat up before it will allow the gas to come on.

The electric element doesn't work.It has power to the plug in but does not heat. The gas works fine. Where is the heating element on the tank?

It will be on back side of water heater, follow hydro wires into metal or plastic cover. (shut breaker off before proceeding) remove that cover and you will find element. Double check thermostat and ECO for tripped reset switch (little button in center of it) while cover is off as well, before going through trouble of changing element.

Electric heating not working

Have you checked for additional switch, perhaps on rear of water heater on side of cover that wiring goes into for element. How far have you gone with it?

What is the inlet temp of the water? If it is cold, your output will suffer. What is the flow into the unit? If it's too fast it doesn't have the proper time to heat the water to full temp. Is this gas or electric? Electric units have more issues than gas. If its electric, one of the elements could be bad. Check your breakers and make sure one of them hasn't tripped (electric). If it is gas, check that you have the correct temp set.

The hot water and central heating wont work together

what size of gas line is going into boiler and water heater? is it black iron ? natural gas or propane? have you checked gas pressure at water heater and furnace ? if they work fine individually then you have a problem with incoming gas pressure. Call gas company and ask them if they would come out and check gas pressure.
