Oils and water are not miscible.
Domestic coil in boiler better than electric water heater.
Possibly the boiler is firing oil and thus the soot from the oil is spilling back into the gas flue
water and if they mix
It will separate and the oil will float to the top, as it is lighter than water.
Water or steam? It makes a difference.

The best option is to put in a separate water heater for the summer and and other warm months when you don't need to run the boiler for heat. When it is winter and the boiler is running to heat the house it will heat the potable water as well. By switching back and forth you will save money on your oil bill.
oil gets on top of water and oil is flamable
Yes, If it is a pressurized system, the water from the back boiler and your oil or gas fired boiler can be mixed. This can also be achieved by using a water to water plate exchanger to preheat the return water from your heating devices. If you have a forced air heating system in the house, a coil can be placed in the main trunk line of the duct work and heated by circulated water from the back boiler.
It burns
Oil and water do not mix...
soda boiling of boiler means removing of oil traces and mill scales of boiler tube material with mild steam heating of filled boiler water and allowing to circulate naturally
If you are using water and not steam there should be a temperature controller mounted in the side of the boiler, that is where the start and stop point of the boiler is controlled.

It blows up!!!
