There is no issue about running furnace with aquahot heaters off in my coach dont know about yours try it and see how it works....
Its listed as a 450 hydronic dual zone heating system with continuous hot water. I think what you have here answers my question and I will give it a try - both electric and diesel switches off.
It seems this system would have lent itself well to radiant heating under the floor. That tile can get chilly and the radiant system would have taken care of the basement as well.
