The range is a DCS five burner.

An inspector will probably spend 3-4 hours there testing every outlet, window, burner, etc.

Had my nose down and working hard over the last few years and the group went on the back burner, but I think it's time to visit this again and get to making it all happen.

Corrosion will happen regardless of whether it's gas or electric, so it's worth doing it for both.Also, my understanding is that since the gas heater's burners are at the bottom, the sediment can act as an insulator, reducing efficiency (although there are varying opinions on this.)Prior to flushing the tank, you should test the TPR valve.

As @Patrick L. points out some gas stoves have just one set of burners.

At that time (~2001) those boilers were realistically 70-75% efficient realistically (or worse so forget about what their rating is) even with annual maintenance / cleaning of the burners.

I know a few oil burner mechanics who are smokers that routinely put out their cigarette butts in a can of oil.

Pretty awesome, and this new strategy can cook on the back burner so it's ready when you need it. 3 yrs is doable!

So that experience put building new on the back burner so to speak. 

One with the burners and a second with the blower fan.
