Direct On-Demand DHW with Weil McClain Ultra 155
I had an indirect on the DHW priority 1. I replaced it with an electric On-Demand that occasionally trips the breaker when it draws cold well water in the winter. Can I just flush my boiler and use the priority 1 for a DIRECT on-demand DHW supply (open loop system)? All of my other loops can be run at close to the same temperature (Mid 120's)? My boiler is undersized for my house and we are superinsulated.
