Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.
I'm sorry but the 2 systems are incompatible. The chlorine in your pool would destroy your home's heating system. You could fill the home's heating system with anti-freeze then shut down the parts of the house you don't use. You'd also have to make some provisions to keep any plumbing in the unused parts of the house from freezing but the best approach for that would likely require an onsite inspection.
Conventional flat plate heat exchangers (the type that typically used with a hot water heating system) are not designed to handle the volume of water required to heat your pool. What you're proposing simply is not done because it is not practical. Using separate units to heat the house and the pool is more effective/efficient. That's not to say it couldn't be done but it would not be cost effective. I don't understand what you're trying to accomplish by doing this.
If you're purpose is to save on fuel costs; the modifications required to do what you're describing would cost far more than the fuel costs you'd save. You'd never recoup the expense.
So you're going to spend $5k+ minimum (including installation) to save a few dollars on fuel costs because your household boiler is a bit more efficient? To answer your earlier question yes the boiler would have to run year round if that's what you plan on using to heat the pool. This might make some sense if you were starting from scratch or needed to replace the pool heater. But as long as you have a working pool heater it's not cost effective.
The call notice is automatic I don't have control over it. Since you won't tell me your motivation for doing this I can only assume it's to save on fuel costs. In which case making this change is not cost effective. Like I said before it will take forever to recoup the $5k plus it will cost to install your heat exchanger. That's my opinion based on 40+ years in the business.
All the people you talked to have a conflict of interest in that they can make a good chunk of money installing this. There's no way this pays for itself in a year or 2. You'd have to save $5k+ in a yaer or 2 I doubt you even spend that much on fuel in several years. I didn't say it wasn't efficient I said the difference in the efficiency between what you have now and the new heat exchanger is not that significant and the fuel cost savings would take a very long time to offset the installation cost many year even decades. So none of what the other folks you talked to contradicts this fact. You can listen to whoever you want. I have no dog in this fight.
