A gravity hot water heating system is the oldest and simplest system to heat homes. It is also the least efficient. In a gravity system, the circulation of water is due primarily to thermal and density differences between hot and cold water. As water heats, it expands, displacing the cooler and less dense cooler water throughout the system.
Tankless heater coil installation on a boiler: this article describes the steps in installing or replacing a tankless coil on a hot water (hydronic) or steam boiler.

You should also find a place where the water heater is near to the faucets that you will be using for hot water. As water is pumped from the heater tank, it rapidly loses heat through the piping, so the farther away the faucets are from the hot water heater, the more energy will be wasted on the way and the harder the heater will have to work.

My current plan is to pump the tub water through a car radiator placed in a 50 gallon drum inside a heat box fed from the rocket stove. lokking for input and ideas.
An aquastat controls the temperature of the hot water in a boiler, typically keeping it around 180°F. But when heating needs are lighter in the spring and fall, that's actually higher than needed, and wastes energy. A modulating aquastat, also called an outdoor reset, senses outdoor temperatures and adjusts the hot water temperature accordingly.
The other primary option for using a heating system to produce hot water is to install an "indirect" or "indirect-fired" water heater. This is a separate insulated water tank that is heated using hot water from the gas- or oil-fired boiler. The indirect tank is usually plumbed to be a separate "zone" on the heating system.
