warm air heaters

[ambrosia]

is there one qualification for warm air heaters, or is there two one for domestic and one for commercial

i have warm air heaters on my commercial and i have CCN1, but today i came across my 1st ever warm air heater in a domestic flat complete with ducting etc,

i should know the limits of my own qualifications but how often do you see domestic warm air heaters

I've got DAH1 which only qualifies me for domestic but I doubt the commercial equivalent would allow you to do domestic.
There are still quite a few about in my experience.

I've got both and I'd imagine that need both if you want to work on both.

Probably more than you would imagine. Ive even seen them replaced on the warmfront scheme with a new WAU.

A friend of mine's parents had their warm air replaced with a new RS one a few years ago. Not sure why anyone would, but they did!
