It needs to be around 250 to 300 gallons for each 100,000 BTUh maximum fire output of the boiler, and should have its own circulator -- possibly with a high limit aquastat on the boiler (circulator on at 190). The tank itself need not be pressurized; you can use a heat exchanger such as might be found in an indirect hot water tank.
On a typical oil fired heating boiler in the U.S. the wall thermostat is controlling the hot water circulator, turning it on or off. It is the temperature of the water circulating through the system (sensed at the primary control on the heating boiler) that actually turns the oil burner on or off to re-heat the water.

A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.
Boilers rely on the water to protect the steel boiler tubes from the temperatures in the furnace which greatly exceed the melting point of the tube material. A buildup of deposits inside the tubes will produce an insulating layer which inhibits the ability of the water to remove the heat from the tube.
service based on heating system criteria: a) Hot Water Boilers – Leave Power “On” - to circulate the hot water and cool off the boiler. b) Steam Boilers – Disconnect Electric – to prevent automatic water feed from opening. c) Furnaces – Leave Power “On” – to circulate the warm air and cool the furnace.

When the CH has been running (from cold) continuously for 1.5 to 2 hours, and the radiators are really hot to the touch, the boiler often trips out (overheat switch pops out). A few minutes prior to this cut-out, there's often a gradual change in tone from the pump as it spins faster, accompanied by the slight 'whooshing' sound of bubbles going through the system (water nearing boiling point).
