Could you shed more light or elaborate on this, please? The townhouse I'm moving to has a hydronic system, and based on the home inspection, and a few quotes from HVAC contractors, they all said the hydronic heating system at the place would be good for AT LEAST another 7 - 10 years. The hot water tank is a rental, but I did think of replacing the rental unit with my own Rinnai RU160iN tankless system.
If it's going to fuck up my furnace, I'll stick to a hot water tank.
