I mean that’s how the water heater operates but when we were talking about installation because that’s what we were first talking about one thing that we get and we you know we have a call center here we take a lot of calls and we know what’s going on in the field with with people out in the field installing these either either di wires or contractors installing these one thing that we see a lot is on a cold tank is what a dry fired heating element yeah you get a dry fire element and actually when I teach trained.
When I trained classes to work in the call center I show this to them will install a water heater will start filling the water heater up and when you’re around the water here what’s filling you can actually hear water rushing into it well and I always trick the class because I hear and I’m like tell me when it’s full because you hear the water coming in right and you hear the water stopping they’re like it’s full and I go up to it and I show them that of course it’s not full because what happens is that water is entering unless you have several hot water faucets open right you trap air in here and so that once the air pressure rises it stops water from flowing in and typically stops right about here up under the lower of the upper heating L right and then you have a large pocket full of air okay and so you’re gonna dry fire the heating element if you apply power to it yes and I think.
We’d have an example of a dry fired heating element right here yes that’s an example of a draw fired heating element now if you look at these you can you can definitely see a difference I have a new heating element and have the dry fired one the new heating element has a nice zinc coating on it shiny like a nickel or a dime very similar then you see the dry fired heating element which is burnt up it’s copper in color because it’s burnt off the zinc plating being draw fired and you just see the metal that’s the metal it’s made from its copper okay and so what there’s an example right there what we’re talking about on the screen that’s an actual dry fire of a heating element so that’s what happens when the what the elements not submerged in water so what we have to do is this you’re going to need to start filling the tank up you’re going to open up your hot water faucets all of them in the home and let them run free so there’s not spitting and sputtering get all the air out of the tank until they run free just steady streams for around three minutes then we can go ahead and and apply the power now you tell me you’d do something totally didn’t hook it up until it’s filled up yeah I don’t even look electricity to the water heater until I have it completely full so when I install an electric water heater.
I install it I pipe it I fill it full of water I make sure that I purge the air out of several faucets and now what’s air kind of stops spurting out I go the extra mile and allow water to flow out of the faucets usually for about three more minutes and then once I close everything up I come back to the heater I check for leaks okay if I have any leaks in my piping I’ll fix it but then that’s one actually make the electrical connection to it turn it on that way I’ll make sure I don’t make any mistakes I’ve draw fired elements before yeah just long time ago and I didn’t know any better yeah and I’m sure people do that all the time it happens all the time it’s not a big deal the good thing is in elements a cheap part right do it and it’s don’t cost a lot of money to fix it all right so you want it to run free and free without spitting a sputtering for three minutes all the water faucets in the house and once it runs free steady stream then you can go ahead and apply power and and start heating water all right so kind of moves us to our next segment so that’s a little bit about dry fire at how this water heater works we’re gonna talk about.
You know some troubleshooting and some some common calls service calls that you might experience and really it’s two of them you’ve got two most common calls that you’re going to experience one of them is insufficient hot water and the other is no hot water and really the insufficient hot water you’re gonna have to do some some questioning to the customer about a couple of these especially both of these really because we have to really know insufficient hot water to a customer their expectation may be different than yours and a hot water to me may be really hot and you may not think it’s that hot at all so we got to find out what what they mean by insufficient hot water you know you usually want to make sure that our what we think matches their definition and when a customer says insufficient hot water it could mean a couple of different things one it could mean that the temperature is just not hot enough right and then two it could mean that the amount it’s not hot enough they’re not getting the volume of water or hot water that they expect a gal velour heater especially.
If it’s a new installation right yeah customers expectation on a new water heater they think that whatever thing if it’s brand new it’s gonna give them more than what they had before that’s what they’re gonna think no matter what you could have a 50 gallon tank in here and you put in a 40 gallon tank just because it’s new they’re thinking they’re gonna get more hot water out of it because they don’t know really how the water heater works they don’t know what the temperature setting was they could have been an older water heater been in there for a long time they could have had the temperature set up higher those are things that we need to find out whenever we take a call like that yeah typically with the lifespan of a water heater until recently most your automatic washing machines and dishwashers required you to have the water set to 140 degrees for the dishes to come clean right so that was a long time ago when the customer may have adjusted that temperature they don’t remember they don’t remember what they said it to the water heaters come factory preset at 120 and that’s usually what they’ll leave it when that installer installs it they don’t usually take off these panels right they install it and it’s good to go and so that could cause the issue or the customer you know says they have insufficient how long exactly so now we’ve got a call we’ve we’ve determined that it is it is a water heater issue so what we’re going to have to do is we’re gonna have to go check the water heater out.
