kev Report post Posted June 28, 2022 During Covid lockdown I was not using my Motor Home. I installed radiant heat flooring. It took about 10 months to complete. Here is what is under my floor. Share this post Link to post Share on other sites

kev Report post Posted August 17, 2022 Thank you wildebil308 and erniee for the recognition. I did not think it was going to be that challenging. I have it in my home but there are no space restrictions. The motor home presented an engineering challenge with space restrictions. A little bit about my floor heat: The engine hot water tank heats the domestic hot water with a heat exchanger. The domestic hot water heats the floor with a flat plate heat exchanger. The liquid is moved with 1 amp 12 volt wet rotor pumps. When parked the the domestic hot water is heated by shore power and/or propane. Share this post Link to post Share on other sites

What model Aqua Hot is that? There was someone looking for one that was all electric. I like my Oasis. I don't have in floor heat but my floors stay warm because the heat blows out across them and the basement is heated. We haven't been any place super cold and don't plan on going. 😁 Bill Share this post Link to post Share on other sites

The only problem I have is that this model cannot run the coach heat and the hot water simultaneously. Hot water out ranks coach heat, so if the heat is on and you turn on the hot water, the coach heat goes off until the call for hot water stops. The AH600 as two heating elements and can operate both coach heat and floor heat. The 450D is easy to work around, timing showers requiring and the requirement for coach heat.

kev Report post Posted August 19, 2022 20 hours ago, wildebill308 said: some type floor heat The reason I took the time to install radiant liquid heat is because I did not like the electric current constantly under my feet and contained by an aluminum box. My coach is all aluminum. I got rid of my water bed heater years ago so I was not sleeping on an electric current. 12 hours ago, five said: cannot run the coach heat and the hot water simultaneously I have the same usage restriction. I need to turn off the pump in the floor when I want a hot shower. The floor does retain enough heat while using hot water for a shower. Share this post Link to post Share on other sites

Why don't you use the diesel burner when you have a extra need for hot water/coach heat? Bill Share this post Link to post Share on other sites

Bill Doesn't make any difference, it will not run both at the same time....have to up grade to an AH 600 to run hot water and coach heat together. Share this post Link to post Share on other sites

I was talking about maintaining coach heat and having unlimited hot water when called for. Interesting because in the owners manual on page 6 it states "The 450D has multiple heating sources: the motor home’s engine’s surplus heat (while driving), one 120V AC - 1650W Electric Element (when plugged into shore power), and a 12V DC powered diesel burner (when dry camping). These heat sources can be used separately or simultaneously." Frome https://www.aquahot.com/Library.aspx However you are correct that it only heats the coach when you arn't asking for hot water at the shower or sink. I think that is to prevent burns by controlling the water temp. I am glad I have my Oasis. Bill Share this post Link to post Share on other sites
five Report post Posted August 20, 2022 It is a great heating system. There are vents through out the coach, just like a stick house, plus you can select which part of the coach you want heated. On my coach I can heat the front and back separately or together. Share this post Link to post Share on other sites
