San Diego contractor and/or help with new hydronic heating boiler install

[Watts]

Anybody here in San Diego who wants to take a look at a new boiler install? Replacing 60 yr. old Raypack boiler. System is copper tubes in slab. Small circulator, expansion tank, and boiler feed water valve. Have supply and returned stubbed out. Will need to flush and recharge system. Probably going with Navien NHB-80H boiler. Comments and advice? Want to come by and take a look. Thanks!

Have a cast boiler that all the flow goes through it? What water temp are you running? Would need to be piped primary/ secondary loop with a condensing boiler.
