We are looking at using a Condensing NG Tank heater for new construction.
I was leaning towards the Polaris, but thought I would see what everyone here thought about other choices...
Vertex, Phoenix, Polaris - any others? Pros & Cons?
We are going to be using it for DHW and Hydronic Radiant and don't need a combi-boiler, and would like to stay away from the tankless system.
Our heat load is only 35K btu so we can easily meet that and DHW with a condensing tank unit.
