But, I do have a 4 x 3 jacuzzi tub that I use on occassion. Space is tight but, not the prime consideration. I like the idea of the "Complete Heat" concept:
1) Unlimited hot water though I know I probably really don't need it considering my use.
2) I do like that one unit handles heat and hot water less parts, burners, electronics etc.. (of course I understand it's all the eggs in one basket too).
3) I also like the efficency aspect.
After the Amana and Lennox units my main concern is I don't want to end up with a discontinued product again after a few years which is where I am now. I'm open for all ideas but, thinking about the Vertex and Polaris especially if I can still use the air handler from the current Lennox Complete Heat system to heat the house.
Right now I'm trying to decide the pros and cons between the AO Smith Vertex or the Polaris. If I decide to go this route.
