timer

Timer is a specialized type of clock used for measuring specific time intervals.
Timers can be categorized into two main types.
A timer that counts upwards from zero for measuring elapsed time is often called a stopwatch, while a device which counts down from a specified time interval is more usually called a timer. A simple example of this type is an hourglass. Working method timers have two main groups: hardware and software timers.
Most timers give an indication that the time interval that had been set has expired.
Time switches, timing mechanisms that activate a switch, are sometimes also called "timers."

    Hot water and heating timer

    Hi, We have a conventional boiler (I think) and have the following schedule set: - Hot water = 1 hr 20:30 - 21:30 - Central heating = 3 hours 17:30 - 20:30 Does it make more sense to have the hot water on at the same time as the central heating ? (cost/performance) Thanks in advance
