A heat storage device keeps engine coolant hot during operating pauses of the engine allowing quick heating during a cold start of the engine. The capacity of the heat storage device for coolant is twice as large as the capacity for coolant of the coolant circulation system and the engine. An inflow line, an outflow line and a ventilation line pass through the bottom of the heat storage device and are heat insulated on the inside of the heat storage device. Hot coolant from the heat storage device is transferred in two portions into the cold engine. The second portion is transferred when the rising temperature of the metal motor mass has come close to the falling temperature of the first portion of coolant that was circulating in the engine. The heat storage device includes outer and inner containers with a high vacuum in the insulating space between the containers.

1. A system comprising: an engine;a coolant circulation system, wherein the coolant circulation system and the engine have a combined capacity for containing a coolant; anda heat storage device, wherein the coolant flows from the heat storage device, through the coolant circulation system and into the engine, wherein coolant that has been heated by the engine is kept hot by the heat storage device, wherein the heat storage device has a capacity for coolant that is greater than the combined capacity for coolant of the coolant circulation system and the engine, and wherein the heat storage device contains vertically oriented deflecting plates that guide the coolant through the heat storage device in vertically oriented meandering paths. 2. The system of claim 1, wherein the capacity for coolant of the heat storage device is twice as large as the combined capacity for coolant of the coolant circulation system and the engine. 3. The system of claim 1, wherein the engine is a combustion engine of a motor vehicle. 4. The system of claim 1, wherein the heat storage device has an inside with a bottom, and wherein an opening of an inlet for the coolant into the heat storage device is located at the bottom of the inside of the heat storage device. 5. The system of claim 1, wherein the heat storage device has an inside with a top, and wherein an opening of an outlet for the coolant from the heat storage device is located at the top of the inside of the heat storage device. 6. The system of claim 1, wherein an opening of an outlet for the coolant from the heat storage device is located at mid height inside of the heat storage device. 7. A method of using a heat storage device, comprising: (a) transferring a first portion of hot coolant from the heat storage device through a coolant circulation system to an engine, wherein the heat storage device has an inside with a bottom; and(b) while the hot coolant is being transferred in (a), transferring cold coolant from the engine through the coolant circulation system to the heat storage device, wherein the cold coolant in (b) enters the heat storage device at the bottom of the inside of the heat storage device, and wherein the heat storage device contains vertically oriented deflecting plates that guide the coolant through the heat storage device in vertically oriented meandering paths. 8. The method of claim 7, wherein the coolant circulation system and the engine have a combined capacity for containing the coolant; and wherein the heat storage device has a capacity for coolant that is greater than the combined capacity for coolant of the coolant circulation system and the engine. 9. The method of claim 7, further comprising: (c) transferring a second portion of hot coolant from the heat storage device to the engine. 10. The method of claim 9, wherein the engine has a temperature that increases after the first portion of coolant is transferred into the engine, and wherein the second portion of hot coolant is transferred to the engine in (c) after the increasing temperature of the engine approaches the falling temperature of the first portion of coolant in the engine. 11. The method of claim 9, wherein the second portion of hot coolant is transferred in (c) in response to an engine starter being actuated. 12. The method of claim 7, wherein a total volume of coolant is present in the coolant circulation system, the engine and the heat storage device, and wherein the heat storage device has a capacity for coolant that equals the total volume of coolant in the coolant circulation system, the engine and the heat storage device. 13. The method of claim 7, wherein the first portion of hot coolant is transferred in (a) in response to a lock on a driver-side door of a vehicle being opened. 14. A system comprising: an engine that heats a coolant;a coolant circulation system, wherein the coolant circulation system and the engine have a combined capacity for containing the coolant; anda heat storage device that insulates coolant that has been heated by the engine, wherein the heat storage device contains vertically oriented deflecting plates that guide the coolant through the heat storage device in vertically oriented meandering paths, and wherein the heat storage device has a capacity for coolant that is greater than the combined capacity for coolant of the coolant circulation system and the engine. 15. The system of claim 14, wherein the heat storage device includes an inner container and an outer container, and wherein a high vacuum exists between the inner container and the outer container. 16. The system of claim 14, wherein the heat storage device has an inside with a bottom, and wherein an opening of an inlet for the coolant into the heat storage device is located at the bottom of the inside of the heat storage device.
