Generally speaking, I prefer gas dryers over electric dryers. That said, when it comes to the Halo-of-Heat design, I prefer the electric version. I currently own (and occasionally use) both a DE806 and a DG806. I did a near total restoration on the DG806 about a year ago and have done rudimentary service on the electric one.
Here are some observations:
The entire concept of the HOH dryer seems to have been designed with the electric version in mind. The gas version is a very odd setup that really looks to be almost an afterthought by the engineers. Electric HOH dryers actually dry pretty quickly given the rather paltry 4500 watt element that is in them (compared to the 5200 to 6000 watt element in other electric dryers of that era.)
The two drawbacks to the HOH electric design in my experience is that the front of the drum gets VERY hot during operation. If you overload the dryer, there is a danger of scorching if items stay pressed up against the inlet area for an extended period of time. Secondly, you need to be pretty diligent about keeping the front drum felt seal in good condition. Thousands of HOH elements have been prematurely shorted out by a stray coin, paper clip or safety pin that worked its way down into the element area and then there is a tripped breaker and a service call. Also, as the felt seal disintigrates it can break off and fall onto the heating element creating a definite fire hazard. I would never leave a HOH dryer unattended while it is drying.
Now the gas version is sort of crazy complex compared to the electric version. In the gas version, the burner is crammed in perpendicular to the drum at the very front of the cabinet. The flame cone sits directly under the front of the drum just inches away from a 3" wide felt seal that circles the entire drum. Because of this situation, Maytag throttled the burner output back to only 18,000 BTUs (compared to the 22,000 to 25,000 BTUs of comparable dryers of the period). Also, the gas version of this dryer used a standing pilot light. Not only does this waste energy, but the by-products of the pilot light burning for years makes a heck of a mess out of the mechanical and electrical "guts" of the dryer. After the restoration, I only light the pilot light in mine minutes before I want to dry. I then turn the gas off immediately after I'm finished.
In my personal experience the gas version of this particular design is slower than the electric. A normal load of towels takes about 50 minutes in the electric HOH. The same load in the gas HOH takes 60-65 minutes.
I'll post some pics of the curious design of the gas HOH dryer.
Here is the front of the dryer with the cabinet removed. See how the burner and cone sit under the front of the drum.
