Well, it turns out that we really did have something wrong with our hydro-hot unit.

Talking with Vehicle Systems they suspected that somehow the fuel nozzle was damaged and the unit was running too rich. They recommended that we get the annual service on the unit which includes replacing the fuel nozzle and the filter and some general cleaning. This is also sometimes referred to as a "tune-up".

We had the service performed today. The RV shop said they could tell from the components inside the unit that it had been running too rich.

So far - no smell. Nothing like what we were experiencing before where we were overwhelmed with fumes - even with the slides in!

So - the moral of the story is that if your hydro-hot seems to be extremely smelly (diesel fumes, etc.), it's running too rich and it needs a tune-up. Also - if your exhaust starts to get a lot of black in it, you need a tune-up.

After we gain some experience with the unit under various conditions we'll decide whether to get the exhaust routed out the back.

Edited to add: We discussed our problem here: Hydro-hot too smelly!!!

Well we've run our Hydro-hot unit quite a bit now. This morning was in the 40s, and still air. We ran the HH for a few hours this morning.

We might be getting a wee bit of exhaust smell in the bedroom area this morning. It's barely noticeable (like night and day from before!!)

The front living area - absolutely NO smell. Previously, the worst fumes were entering the coach in between the front slide and the pantry - I mean it was BAAAD. This is right above where our HH is located in the basement. No smell at all now.

Can I say WOOHOO again?

Audrey
