solar water heater/waste oil boiler

Daddy Tanuki said:
the yellow arrow is the pump thats on it. I was going to replace it with a larger, higher pressure fuel pump form a car with a pressure regulator to make it adjustable. supposedly nothing was wrong with it, but i have not had time to play with it yet. it was cheap enough i bought it on the assumption that it might be toast.

From what I've seen the pump might be fine you can get a siphon jet(burner orifice) that integrates compressed air to get the oil to the required pressure.
The thing that seems like a bit of work is the oil heater which also needs the compressed air line to be sunk in the oil via coil so the temperature of air and oil are relatively similar.

Did you take a look at the pdf I sent seems the riello heavy oil burners have the heater and everything needed included though you would have to decide if $500 is worth it compared to the time you would spend diy`ing one, there also seems to be stockist there in Japan.

stock in Japan? that sounds interesting, depends upon the price though as the Japanese run the cost up on anything imported to insane levels sometimes. I have seen triple and quadruple the cost for some things.

got a link for the japanese store?

https://www.san-eee.com/en/ seem to be a riello stockist I can't see the heavy oil burners in their stock but from what I've made out they claim to have them.
Riello was Italian brand, but are now made in Ireland I think, but some parts are imported from Japan (maybe control module)

Thanks, i will have to contact them tomorrow as today is a holiday and everyone is closed. They are actually close by in yokohama which is a 30 minute drive from my primary residence in Yokosuka.

also how is it that everyone can find all these links for japan, but when I do google searchs for various things I can never locate squat? I ahd the same issue with a slide in truck camper. searched in english, japanese and could not find diddly squat, a guy form the states found two companies that make them here in japan but he was in the states and using google. I tried the exact same search terms he used and came up with nothing. wonder if they have some sort of filter for google here. I might have to look into a VPN or something. never used one to date, but might look into it now. one thing I can understand but all I could find for oil burners in japan were japanese made units that burnt only kerosene and heavy diesel and neither would answer when I spoke about burning waste oil.

I found obscure forum that specialise in people burning waste oil many people seem to dilute 50/50 kerosene and waste oil, some guy burning anything from brake fluid to heavy plant oil. I'll try look for the link if you want to trudge through it.
 
I have a friend that used the drip oil onto a hot surface method to heat his garage. That was until the insurance agent said he would be canceled if he didn't remove it.

Vapor chamber that's the style I've been making for my neighbour I've just been using brake disks, welding the lug holes, fitting a blower chamber to the hub space, drilled stainless pots as blast chambers and glass fibre wicks for ignition.

yep not surprised. here in Japan getting insurance on a building is a waste of time unless it is a new structure as they will pay you almost nothing, no matter how good of shape its in. this is because the Japanese government considers any wood construction building over 25 years old as having no value, and the taxes drop to near zero as a result.
I just spent 8.5 million yen to remodel the exterior with new insulation, under cladding double pain windows, new door top tier concrete composite siding, the whole works, and if I spent the 3k a year they want on insurance they would only pay me about 1 million yen for the structure if something happened to it. so after 3 years of no insurance I have already saved as much as they would have paid.

Part of the reason of the separate outbuilding for the water boiler and oil burner is for safety, part of it is simply because the cabin/house is small and I want to move the washer, and install a dryer in the extra space in the outbuilding.

Yes it most certainly looks dead and most of the photos are dead links but there's a fair bit of good written information.
 
so SanEEE was a bust, they only import the kerosene burners modified slightly to use Japan power and nothing else, would not even talk about burning used motor oil. going to see if I can make contact with the parent company and order direct.

any clue on what model of the riello would be the easiest to get the parts for to burn waste oil?

If your going to talk to them your best asking them it's more how many kw you want. I'm guessing their heavy oil burners would have the heated tank so it's just being able to source the siphon jet to burn the waste oil.
 
The radiator heaters I purchased have an output of 14kWh or 50,000 BTU's and I have two of them, however I am anticipating that both will spend more time off then on. so if the heater itself can supply say 50kWh then it should be fine, larger is ok to an extent but too large would just waste fuel and not heat any faster. smaller would be OK, just burn time would be longer.

so say 30-50KwH?

The company is based in Ireland so their command of the English language should be fairly good I'd drop them an email.
There was talk a while back of them producing a purpose made waste oil burner not sure if that's changed but my experience with them was always top notch.
 
just got a reply back from their canadian entity so we shall see what they come up with. I owuld much prefer to simply buy a unit that is proven. and then DIY the boiler portion.
 
If it's an enclosed unit with everything built in a fire stop valve could be used and be practical, rather than having a large preheat reservoir that could sustain a fire. I know oil is hard to ignite but when you have a decent heat source nothing is impossible.
 
Just note make your baffles as simple as possible doesn't matter if their made out of AR plate they will inevitably corrode and fail best to make them as easy to replace as possible

you will really twig at my boiler design, its simplicity at its finest and at 10mm thick steel walls will outlast me
:ROFLMAO: i really have no way to describe it, but without nailing the burner down i cannot give you a layout. suffice to say its an overgrown version of the hot water heater for my outdoor tub that is sold here in japan. matter of fact, here some photos of one of them it will help you visualize.

this is it with a kerosene burner attached, and is exactly what i use to heat my 800 liter outdoor bathtub with

here is another angle without the kerosene burner attached.

so imagine a mondo sized version of this made of 10mm thick casing for the burner tube area, with a 5mm thick water jacket. not the most efficient, but bullet proof and as above probably outlast me.

I would make the burner area as replaceable as possible, only boiler I've seen last was in the rolls house(rolls royce) they used it to warm their garage it's was 20mm+ cast iron unit built in the late 19th century the baffles were easily replaced with 10mm mild steel and the burner we swapped out in maybe 2015(for a riello) it was a kerosene boiler but since it had no secondary burn it used to corroded pretty easy from the sulphur dioxide though the cast iron seemed to hold up pretty well for its age.
