Nice work. A few thoughts-

On our vessel we have a fairly standard hydronic heater setup. It also has the ability to heat the entire vessel via a small plate heat exchanger off a valved short coolant loop from one engine. This way the engine's coolant system is decoupled from the hydronic coolant flow.

Given the hydronic heat exchangers propensity for developing internal leaks or at fittings, this decoupling adds a safety factor in eliminating engine over heat potential. This type of heat exchanger could easily be installed on your heating loop.

You didn't mention aqua stats. Are you using them to shut down heater fans in warm areas while fans activated by thermostats in cool areas call for heat?
