1. When testing AH how do I know when the fans are running? Are they easily hearable inside the DP?

2. I'm zeroing in on a great 2007. Haven't seen it but researching it now. Brochure doesn't say anything about 'zones' as we read about in the newer ones. Anyone have a '07 QSZ?

Have a great day - Richard

Yes you can hear the blowers inside the coach. Normally zones are different parts of the coach, salon, bedroom, bathroom, bays. Different in different coaches.

As long as the boiler fluid Glycol level is right for the temps it will be exposed to you don't have to worry about the A/H heating lines and coils freezing.

The concern is that at those temps the domestic water lines could freeze in the Boiler tank if it is off and the RV is not winterized. If you winterize the RV and your boiler fluid is correct you could just turn it on when you wish to actually heat the RV saving you some money when not in use. This is what I would do in that situation because if you rely only on the A/H heat alone to keep things from freezing and you have a problem ( even a simple one) that causes the A/H not to run without winterizing the plumbing you could freeze and bust the domestic water lines in the A/H and that would be a expensive repair.

There have been several folks that can vouch for the freezing up due to not flushing the water lines and spending upwards of 5K to get back in operaton

So don't leave the unit full of water and be sure the drain valves at the AquaHot are both open after flushing with antifreeze

A well insulated coach will take you anywhere in cold winter months for traveling or just camping.
