diesel coolant heater as base board heater

came across what may be a good price on a webasto coolant heater (diesel). 23,000
80,000 btu.

wondering if I can use this to heat coolant and pump it thru base board heaters.

Would use this as heat in my log cabin (12x16 in size, 4" logs, thermal windows).

problem may be... according to one spec. I saw for a newer slightly larger model was 0.4/gal per hour diesel use.

I know so far not many have found much success running these on WVO. Have not found much info about running them on blends yet though. Have not read bout how they do on bio-d either

Also don't know if I could create a thermostate control for it. such as when room hits temp can I use a thermostat to shut down the 24v to the unit and have it kick it back on again when temps drop below the set temp.

by the way.... my temporary heat solution I bought a month ago.... is.... you guessed it.

LOST IN THE MAIL!!!! with no tracking number and no insurance.... Mad

SSoo I got NO HEAT in the cabin now. In part this is why I'm sleeping in my office at work in hopes the post office finds the damn thing.

That would be easy and prefered. I have so little room in the cabin having the bulk of the heater outside would be ideal.

Talked to Webasto.

He said the specs on this on is 0.8gal/hr OUCHHH

but... they make thermostates for them that run off radiator coolant temp and felt this could be used to shut her down when the coolant temps are up to snuff for my application. Sounds like the same switches they use to shut off aux. 12/24v radiator fans.

They do make different size nozzles.

This is sounding interesting.

will keep ya'll updated.

talked to another Webastco tech. The unit I am looking at is an 80,000 btu.... YIKES.... but then again there are losses in transfer from fire to coolant to surroundings.

On the unit Im looking it is designed with a replacable bolt on thermostate set for 172 coolant degrees. Non adjustable.

Learned that this thermostate... when coolant temps reach temp.... it shuts power to the fuel pump. Remaining fuel is burned off. Coolant pump, igniter and fan (air feed for the burner) stay on.

If I get this.... think I would time how long it would take to burn off fuel after fuel pump shuts off...

Then.... with some help from Guru's in places like here... design a thermostate to replace the OEM..... that is adjustable..... and includes a timer?? or something to allow the fuel to burn off then shut down the fuel pump, igniter and fan too.

Wabesto makes several sized heaters for trucks and RV's, This one has two settings, 2.5KW and 5KW, 2.5 KW burns .3 LITERS/hr, 5K burns .7 liters/hr.

My 1200 watt electric space heater works just fine heating my 200 square ft living room and it never runs more than half the time, watts is watts, 2.5 KW from the Wabesto should at least equal something like my 1200 watts to the house even with all the losses in the hot water system?

I recently spoke with a local garage mechanic that repairs the local school busses, he said the school busses were equiped with some version wabesto heater, don't know just which model but he indicated they put out enough heat to keep a full sized poorly insulated school bus nice and warm and if they wern't working the heat from the diesel engine was not near enough to keep the bus warm.

The wabesto web site links to THIS RV website about a hot water system used for both engine heat and interior space heat, I didn't read it enough to see if it uses a Wabesto diesel fueled heater or what?

Someplace on the Wabesto web site (Maybe found it someplace else on the net, don't remember know) there used to be an exploded parts view of the Wabesto heaters, I researched it a few years ago, the design of the burner does not lend itself to burning anything but diesel or kerosine, forget the details just now but I will look back into this. I think the Wabesto heaters use a hot wire igniter, these don't work at all for straight veg ignition, don't know if they work with biodiesel or not, but I suspect it would be marginal at best.

I just checked the WVO board, there is a discussion going about fueling a wabesto with biodiesel or SVO HERE, looks like they don't like either one.

I did not buy the unit. Doing price calculations on the other parts needed (radiators etc.) it was just outside my budget.

cant use an elec. base board heater unless I run a generator all day. Im off the grid.

Yep my second purchase of one is in the mail. UPS this time so I can track it.

Propane RV heater -- Be carefull - don't know what style of heater this is but if it is an infrared ventless type it is still dangerous for carbon monoxide. I had a trucker friend die in his sleep from this when snow cornaced over the truck cab and closed off the 3 inch open space he left at the top of the cab window.

It will also create a LOT of moisture in the small house (HERE).

I still like the idea of a small propane salvage yard water heater located outside with a basebord water radiator inside and a shurflo pump to move the water, use radiator hose to connect it all up. The built-in water heater temp controller will turn the burner on/off automatically as needed and the electrical power for the Shurflo circulation pump can be connected through a normal cheap home mechanical switch type wall thermostat, these are normally used on home 24 volt AC furnace thermostat circuits. They usually use a pea sized sealed glass capsule full of mercury to do the actual electrical switching, they will handle the 6-8 amp load of a 12 volt Shurflo water pump just fine.

Thanks Tim.

I scavaned an older 12v Peltier cooler from a garage sale my students are having to raise funds for our competition season. My plan is to use this as a dehumidfier. Just turn it on cool setting with the top off and let it attract water. It draws 5amps at 12v.

The Mr. Buddy heater I'm getting is a catalytic ventless but it does have an auto shut down for low oxygen.

ALL "ventless" heaters put toxins into the air you breathe. They will also produce more humidity than your cooler will absorb. Go cheap, die quicker.

Low oxygen shutdown -- Unfortunatly, from what I can tell this is a good bit of a bogus statement, I just picked up a similar infrared space heater (18,000 BTU natural gas) from my local salvage yard, I don't find anything in the heater that is different from a normal gas heater. I think the statement means that once the oxygen is low enough that a flame can not be sustained the burner goes out, once it is out the normal pilot light also goes out so it won't automatically re-light, unfortunatly, by then YOUR pilot light has also gone out, especially in a small space, wish it weren't true but my trucker friends death proved that it is.

Peltier cooler -- I also just picked up two salvage yard Avanti table top refrigerators that use these as there cooling element. The Avanti frig advertises that they have an automatic defrost cycle built into the electronics, from reading customer posts about these friges, apparently there defrost cycle does not work well as most posts were about ice building up on the cooling fins and causing the fan to make lots of noise by hitting the ice. I am now back engineering the control circuit to deturmine just how this works but I have not yet found anything that looks like a defrost, at least not what I would call a defrost. These peltier solid state units will run in reverse if the input voltage is reversed, the cooling fins will get hot rather than cold, I was expecting to find this used for defrosting but it looks like they don't use this method. I intend to design a control circuit that does use this for defrosting as well as allow direct 12 volt DC operation of the refrigerator. Anyway, John is probably correct in that it is not large enough to remove all the humidity produced by the heater, the cooling element will also likely become completely clogged with ice in a few hours.

I tried using one of the very small bottle mounted MR. Heater infrared propane heaters inside my very well insulated Dodge van once, It literally had water streaks running down the walls after only a couple of hours in sub-freezing outside temps.

My understanding of the auto shut off in low oxegn.. is simular to what you said but a little more exact.

a thermocouple is placed more exact in a spot to where a reduction in oxygen decreases heat output of a particular spot thus allowing the thermocouple to quickly cool and shut down the unit.

This knowledge came about from a trailer camper buff who discovered that his unit would NOT work at higher altitudes. (over 7000 feet) Via some phone calling to tech. support the information I describe above was relayed to him . Higher alltitudes also causes lower O2 thus creating low temps by the thermocouple and shutting down the fuel flow.

You can believe someone who is trying to sell you something or an air quality professional with no vested interest.

"Tech" as in company engineer not salesman. Who is the air quality profesional you speak of and have they investigated the units sold these days or the ones sold in the preceeding decades?

The RV and Marine world has begun to accept the catalytic heaters over the last decade as safe enough to use now compared to those of the past. The newer catalytic heater auto shut off stuff has come a long way from all the material Ive read on it in the RV discussions. I just sumerized it here. There is some very heavy tech on those boards just as their is here.

but yes room will be set for air to have an entry. That is a given in my mind but I should have mentioned it.

For cross flow to be created would it be best to put an air vent (intake) in the floor if cracked window is used as air escape. (hot air rising?) My floor has open space below it.

Canada is a world leader in indoor air quality. The building code specifically prohibits ANY unvented combustion appliance in a residential building. Use at your own peril.

that makes since. Burocracy is the slowest in getting newer technology into the market. Not that this is allways a bad thing.

Thank you very much for the warnings though.

To most Americans, Canada is a socialist country with only 30 million people. We place 10x the value on an individual human life as compared with America. The company selling your poison pot heater knows you'll get sick slowly enough that their lawyers can keep you tied up in court till you die. Caveat Emptor & Bon Chance

I thought Texas was never supposed to get under about 70 degrees...

If you choose to go with the radiator coolant heater,

There are several "Steam Radiators" on both Craigslist, as well as E-Bay. Unfortunately, most of them are in the North East USA, and probably brutal with the shipping.

Most are antiques, so they may need some sealing, but would be excellent to radiate the heat into your living quarters.

Or... You could go for more of the "Redneck" look by taking a car radiator and electric car fan, and tucking that into a corner of your house for a heat exchanger.

The BB system: http://www.fieldlines.com
has a section on home heating. Of interest, there is an "outdoor wood setup"

Also some comments on VO and Waste Oil Heaters.

Unfortunately, most oil heaters require 110/220V power.

No John, were not socialist.

We're just blessed enough to have adequate natural resources to dig up and chop down to fund our social programs with, that's all. (Don't start about Tommy Douglas-I know where we got universal healthcare. We can afford it. Can India?)

We were founded on colonialism just like USA, we just never had the cajones to have a tea party over taxes and representation. We still don't.

Another difference was that we never used genocide to the same degree that the pilgrims did when we stole the red mans' land. That and we never used slave labour like they did (northern railroad etc). Some historians have claimed that Canada was the first location where germ warfare was used. Apparrently, some British officer and some Catholic minister got together to innoculate blankets with smallpox, cut them into small patches, then distributed them amongst the native population as a supposed defence against smallpox. Sad image eh?

Stephen Harper is a weaker shadow of George Bush (who, in my opinion, is a weaker shadow of Darth Vader). I'm ashamed to admit that I voted for that turncoat the first time. Not this last time though...

The North Alberta tarsands' refineries are oozing toxic goo in their tailings and Ralph Klein doesn't miss one nights' sleep over it.

We have universal healthcare and public education, but it's not like there are no problems with those two systems (I admit it's still better than theirs' though).

This isn't directed at you, but what pisses me off is when citizens of any nation are BLINDLY patriotic. I love Canada, despite Her imperfections, not because I delude myself into thinking She's perfect.

I've heard that many THINKING patriotic Americans can't dare voice any real criticism about their nations flaws for fear of being labelled as being unpatriotic.

Real patriotism means that we love our nations enough to admit their faults so the issues can be dealt with, not ingnored until a crisis develops. Witness the corrupt stupidity that brought the current financial crisis down south...

I agree with the slogan "America-Love Her or leave Her", but I really wonder how many of those who love Her enough to stay also love Her enough to try to make Her better?...
