We need a new steam boiler and would like to have a zone for 3 hydronic radiators (K8 with Danfoss valves). Better to get a built-in domestic coil and use that for the hydronic zone or use an external heat exchanger? Is the first option significantly more expensive then the other? Is it worthwhile? Finally, any thoughts on what brand boiler to use? Thanks.
