Best Replacement Furnace

[jbwillingham]

I've got a '71 Tradewind Twin that I purchased and the PO had removed the furnace and was just using an electric space heater. Can anyone suggest a good replacement furnace?

I think it originally had a Suburban NT-16. Should I just go with the newer NT-16SEQ? The trailer is only 25' feet and it doesn't look like the heat was ducted, so I am thinking of going with the same ductless set up.

I could be mistaken but I believe your trailer would have come with a ducted NT-30.

An NT-16 is really too small. You'd have enough heat down to around 32 degrees, and below that, it wouldn't keep up, especially in the wind and at night.

In general, the Suburban NT series are the best available fit for the original location. If you are in fact going to be using a smaller unducted furnace you could consider the Atwood Everest also. It has a lower amp draw if that's important to you. I don't think there's much difference in quality or price.

The original should have come with an NT-30.

That's what a replacement should be.

Maybe so. I am kindof flying blind because not only was the furnace removed, but the entire cabinet assembly was gone. I do still have the water pump, kitchen sink and oven, but the furnace and all the cabinets were gone, as well as any ductwork if there was any.

I don't see any evidence of ductwork. There are no cutouts in the 1/4" bulkheads where the ductwork would have gone back to the twin bed area or into the rear wetbath.

The service manual I have for the '72 version shows a diagram for a ducted system. Maybe '71 was done differently.

In looking at my Owner's manual, it says a 23-25 ft. AS would have a 22,000 BTU furnace. Would that have been the NT-22 then?

Yes, but you can kick it up to 30,000 for very little more money, and they are the same size.

Here is a link to pictures of the the furnace I just removed from my '71 23' Safari Twin. '71 23' Safari Twin Suburban 22 Furnace

If you want, I can send you picts of the ductwork layout and even sell you the galvanized ductwork (I'm doing a full renovation, but don't know what I'll use to heat with yet...)

KEI, here is what I did for a furnace. It has been tested to 9 F, worked great.

The pic is of the TV, but the furnace made the frame.

J. Morgan,
Very nice! Who is the manufacturer and the model? (I really like the modern approach to heating the AS).

I just found your posts today. Unfortunately I already purchased a new unit and decided to go with a ductless unit.

It is a Williams direct vent wall furnace,

It is a residential unit, but I used it anyway. I bought it because it only needs a single two inch diameter vent tube for intake and exhaust.

I was worried about its listed BTU capacity, but it heats my trailer well and quickly even when it was very cold in the single digits and low teens. It is quiet and effective and works while I tow.

It was white as pictured in the link but I painted it. It does require 120 volts though. Not a real problem for me I run it through an inverter like most everything else in my trailer.
