Sharp Dressed Highboy

The Hi-Boy makes a nice lookin' boiler...
Now I'm torn, Hi-Boy or AA-130...

80's Mustang and drag racin' just don't seem right...
The time frame; not the car...
Have a customer who did the pics '67-'72...
For the 'real' drag racin' cars...
Some pretty wild pics...

My vote would be for the Highboy. 54 gals of water, 7gpm coil. Mine will also be "fully dressed" when I set it up.
I believe Scrapper has one for sale right now.

As much as I enjoy the classic muscle cars, it's a drag race, not a car show. It is very tough to beat the price and weight/weight transfer of a Fox body Mustang.

Back to the boilers...everyone's situation is different, so I can't say if an EFM or AA is right for you. An EFM Highboy is considerably more of a powerplant than an AA130, but you may not require the extra capacity.

The AA-130 would work at the current diggs...
1700 sq/ft and DHW...
The home situation may be changing, as in much larger...
4200 sq/ft, DHW and 3 more bodies...
So how would the Hi-Boy handle a 250k btu/hr load...

The pics were taken during '67-'72 of the actual races...
They were not yet 'classic'...

How did you arrive at that BTU figure?

Just based on the two oil boilers and 4-275 gal tanks...
Both boilers have 1.1 gal/hr burners in them...
3000+ sq feet is on one level so lots of ceiling...
Then there is a large shop space 28x32...
Then there may be a small hot tub/lap pool added...

Mine is about the same, athough I live further south and my BTU requirements are different: 3100 sqft house, 2500sqft shop. I also plan on building a 2400 sqft garage, but heat not required on a fulltime basis.
Anything more than 200k BTU load may require a EFM 700 or 900.

My house has a 250,000 btu/hr oil boiler installed...I have an hour meter on it and the most I ever saw it run on a below zero day was 10 hours. If I had based my coal boiler just on the size of the oil boiler, I would have probably ended up with an EFM 700. Once I took the time to see what the actual load was I was very comfortable installing a 520. It has been a year since I installed it, and the only time it ran almost nonstop was a -22 degree day, and that was on 5 teeth (50% output).

Forum member cArNaGe also thought he needed a 700 for his 4600 sq. ft Victorian; last I heard his 520 was on 6 teeth and doing the job just fine. The point is that you need to do your homework and get a better idea of what the heat load is...I wouldn't be surprised if they used one oil boiler most of the time. I don't think an AA130 is large enough, but you may find that a 520 will do the job.

Yep, need to do a heat loss calc but don't have the access I need to do one yet...
So the 520 has more output than the 130?...
And the extra boiler water in the Highboy helps reduce the shock on a larger home heating zone or is that more for the internal DHW coil...

Yes, nearly double.

Yes to both, but more so for the tankless coil...with proper near boiler piping and controls you shouldn't have problems with thermal shock from a high-mass zone.

To get that high an output you would need the AA-260 or an AHS S260. Twice the BTU's of the AA-130 or AHS S130.
