Had a plumber recommend the Lochinvar knight boiler KHN085. But I was also looking at Navien Combi or Rinnai Combi and a Bosch Greenstar. I know there are a lot of brands out there. But out of these or some other ones which are the Best of the best?
I really want to Combi boiler but they do not make one with a 10:1 turn down.
