Main thing you need for heater repair is a good source or parts and wicks, other than that they are very simple - Forced Air (Salamanders) require correct air pressure - common things with them are the ignition, filters, nozzles, end caps cracked, rusted out check valve springs, etc. - usually most of them we can have fixed and working in under a half hour - you'll want an accurate low pressure gauge (Desa HA1180 works good, or a Dura Heat 21-1115 ) We are service center for Desa (out of business but still carry parts) , Dura-Heat, and Mr. Heater so we have access to all those parts as well. - Even those are all so much alike, it can be hard to tell which manufacturer you need to get parts for, but there *are* frequent differences that require caution in ordering parts.
For kerosene wick fed heaters they are all generally the same - they need good air flow and good quality wicks and pristine quality K-1 Kerosene fuel. Most of the time repairs simply involve a basic tune-up - new wick, cleaning carbon away, blowing out dust, making sure the mica windows are in good shape, drain the old fuel and put in fresh, let wick soak at least an hour in full down position before lighting - nothing too complicated with them once you have had a couple different configurations apart and understand how they work. - If we had enough customers (We're in coal/wood stove country here) we could turn out 10-15 tickets a day with ease per tech. Judging from our online sales (ebay, amazon, web store) they are still a lot of them out there and we have wicks for just about (probably 90%) of the heaters made since the 70's and every season we're increasing our "on the shelf" stock of heater parts as well (knobs, chimneys, glass mantles, etc. etc.) - It isn't rocket science... and actually diagnostics can be easier than with small engines, the work for the most part is relatively light weight (Hardest part is lifting the heater to a work bench) and rarely ever anything more than screwdrivers, pliers, a couple adjustable wrenches and a pressure gauge needed (a DVOM for testing igniter systems is handy)
That is one of the reasons why I set up the "other stuff" forum (Power Tools and Miscellaneous - at the bottom of the board index) for posts regarding that stuff.
