Well for today’s equipment autopsy we have a Renault Infiniti continuous water heater it’s a gas heater and it doesn’t work it was donated by a friend who got it off of friends just as junk I also got this neat little oil cooler with the screw on attachments the oil filter housing it’s kind of neat don’t know what kind of car it goes on but that’s worth keeping this thing here I just want to strip it down get it out of here been raining continuously for the last two days so I have another chance to move big stuff outside like the engines and just clean up in here I really got to start pulling big things out and then get into cleaning because otherwise you’re just tripping over everything anyone who’s got a hobby shop knows what that’s like so I’m going to pull this thing apart and you can state it and watch for the experience and quite interesting inside I think this one will have a stainless steel heat exchanger a lot of them do or if we’re lucky it might have a copper heat exchanger they’re worth a bit a scrap I think it’s leaking I don’t know for sure.
I think it actually leaks or it’s got an electronic problem either way I just want the circulation pump out of it above everything some of them do circulate continuous water for instant hot water okay there’s the data on this water heater for those of you who are interested in that sort of thing yeah forty four point five kilowatts it’s pretty impressive cause plenty of warnings there’s a gas appliance so it’s going to be approved and warranted you can get lpg kits for these but little bit hard to find unless you’re buying brand new from Rene in which case probably paying for small fortune it’s got the jet sizes there though you can always plug the Jets up with solder and then read drill them it’s not hard to do and of course everyone is crazy about energy ratings although this one’s faded out of existence now it’s a reason why a lot of people buy new appliances and throw the old one in the bin is because it has a lower energy rating like a fridge that’s down here go off and get thrown in the bin while it’s perfectly good for a fridge it’s up here in the middle big waste of a machine a lot of expense making a new one and reprocessing but that’s what a lot of people do so on with the autopsy oh wow does this thing have a lot of crap in it for a water heater that’s what makes efficiency.
These days making all this electronic crap I convert a microwaves and inverter air conditioners there might be power efficient but God knows what kind of consumables they use making them I see a big printed circuit board with a rack of dip switches down there mains input which is currently switched off at the panel but neutral still active and we are going to put power to it and see what it does it actually has a copper heat exchanger and one of the guys who works for Renault when I was working at the scrap yard he would bring in the poll back of his van full of these coils that had failed prematurely because they made out really paper-thin copper they just seem to have a horrible failure rate probably why this one was canned as well there’s a lot of signs of water getting through the bottom of the cabinet there’s a lot of corrosion an ongoing problem up there apparently these do have a pretty horrific failure rate don’t worry I’m not getting any kickbacks from Reno for doing this video they probably won’t like me but this is quite a interesting unit I was wondering what they look like.
I’ve walked past them at the scrapyard before we then they complete with the cover on just thing it’s just a burn a rack with a valve on it and a copper heat exchanger but this is incredible someone did say they had headaches they had our circulation pumps in them which is I think that thing down there and I guess they’re right there’s two water passages aluminium manifold and then it’s gone up to this helix quite interesting and obviously a combustion blower in there that’s a centrifugal blower but sir turns and power on well as I say in the movies fire in the hole your valve or something hmm sound like servo motors and valves and it’s not doing anything both waiting waiting for a gas pressure signal which is that’s gas input oh I see that’s a gas manifold another water manifold silly me yeah it’s probably waiting for a gas pressure signal like something there that looks like not so much a solenoid but more like a pressure switch actually no sorry it is a solenoid I’m having a great night tonight yeah that’s not a solid that’s not a pressure switch that’s a solenoid hmm I’m having to get this thing to do something exciting well I guess I can’t without fire gas now let’s just rip this damn thing apart I don’t have time for the fiddly mucking around stuff.
I know it’s busted oh I said it doesn’t work so I’m going to take his word for it and I’m not really going to bother using it for something important they’re not reliable enough I’m starting to get into the thing not easy is the blower which is packed up full of dead moths yeah they’re there it’s about six dead moths jammed inside it so that’s why we only got half the airflow it needs and they’re up inside the burner box hmm cut that also going to put obscene amounts of power through it it’s a 40 I think it’s 48 volts induction motor or something like that probably not actually it’s got so many Y’s on it it either way that thing will burn some of these silly little coils it’s just retarded amount of complex stuff for a water heater all you need for a water heater is a couple of thermistors or like wax stats a burner rack and the heat exchanger preferably made our thick heavy copper none of this paper-thin stuff that’s all you need for a heater mount it outside okay if you want to put it inside you do need a combustion blower but that’s about it what’s with all this electronic shit and sensors and things how’s that efficient I mean this super efficient till they break and you have to buy a new one I don’t know how old this thing is but it’s not very old it’s just so wasteful.
I mean not dismantled quite a few instant and I suppose they call them instant water heaters particularly the old ones the ones made by Yonkers and Bosch they are really simple they have a solid brass valve block a burner rack and a copper heat exchanger that’s it there’s none of this stuff there’s no fancy vowels or solenoids maybe one solenoid that’s about it no they’re misters like that one there came off the top of this loop there’s another one there was another sensor there which is down the bottom now there’s about four sensors on this copper part there’s a few on this burner box there’s four or five or so on the water outlet yeah that’s the outlet there says it semester on that there’s some kind of sender on there with four wires going to it there’s wires going into a block down there why why do water heaters have to be so complex this isn’t saving energy this is wasting energy manufacturing all this shit I like high technology but there’s some places where it just doesn’t belong and if you build water heaters like big chunky bricks like they used to be they can last until forty years down the track when they eventually do corrode through or it just gets so hard to buy parts that it’s not worth replacing it like the old brightest Buffalo gas heaters though lasted my mum’s won’t actually lasted 22 years before she replaced it with a Braemar as an eco star heater and that brie mark that Braemar eco star is not going to last as long as that 23 year old brightest buffalo it’s not built as well sure it’s efficient.
