I am planning on purchasing a 2016 Tuscany by Thor that has an Aqua Heating system.I am unfamiliar with this system and have a couple of questions: 1.) Can it run on 50-amp electric service regardless of outside temperature? 2.) If I run it in diesel mode, how much fuel does it use per hour? 3.) My new coach also has 3 air conditioners with heat pumps. To what temperature are they effective? 4.) Will I have on-demand hot water regardless of which system I use? Appreciate any information anyone can offer. Thanks 2006 Tuscany soon to be a 2016 Tuscany 2014 Jeep Wrangler
This is an alert to all Aqua Hot users. Our AquaHot's boiler cap was stuck and allowed the boiler to boil out 11 gallons out of 16 gal of coolant over a period of I don't know how long! The cap was so deteriorated (brittle) that the rubber seals came apart in pieces when I removed the cap, which I had to use Channel locks to remove. The missing 11 gallons of coolant was causing the temp of the hot water to fluctuate, which I thought originally was the mixing valve; but after circumstances led me to check the coolant level I found out differently! After cleaning the Boiler cap neck, which was very difficult on our 04 Monaco Exec, because of where it is located and the size of the AquaHot and filling it with coolant, the Electric Heating Element burned out and I had to replace it. The Heating Element Replacement requires that you drain the boiler. Well there went the 11 gallons of Coolant I just put in by pumping it in with a new Weed sprayer, which was a real chore, because of where my boiler's cap and inlet were located! I did have an unused 40 gal blue tank, that I was able to use to recycle the 16 plus gallons of 50/50 coolant mixture. Note: Use Distilled water along with the coolant to achieve the 50/50 solution. This will keep the corrosion down in the room heat exchangers and save you money and trouble in the long run. The AquaHot Owner's Manual & the AquaHot Repair Manual says to check the coolant level in the reservoir tank and neither manual mentions checking the level of the fluid in the Boiler tank OR what type of Coolant to use!. The tank has a radiator cap on top of it like a car's radiator. Do not trust just checking the reservoir's fluid level!!! I would advise everyone with an AquaHot to check the boiler's coolant level. Wait until the boiler is cool. If you can feel that the radiator cap on top of the boiler (Just like a car's radiator cap) is cool to the touch, along with the area around it remove the cap slowly and if the level is correct and full, the coolant will be right up to the cap and may even overflow as you remove the cap. If you cannot see or feel the coolant level go to: http://rvhydronicheaterrepair.com/RVHYDModelInfo.htm and see what type of coolant your AquaHot uses and fill it up. Note: you should find out what type of coolant your AquaHot uses anyway! In any case you should check the boiler cap once a year and replace it every 2 years! You will save yourself a lot of headaches & heartaches, along with a lot of money in repairs! God Bless and have a supper day, Larry the Tweety Coach Guy
