A bimetallic strip is two different metals glued together. When the temperature changes each metal expands (or contracts) but by different amounts, so the strip as a whole ends up bending. This bending property can be used to turn on (or off) a heater switch.
Bimetallic strips consists of two strips of fused together along their length. On one side, you'll see one metal; flip it around and you see another type. Since metals don't all expand and contract at the same rate, this bimetallic strip will be straight at only one temperature. Heat the strip up and the strip will bend because one metal will expand more than the other. This bending of the bimetallic strip is used in thermostats to regulate temperature. This strip provides a closed circuit to a heater. When it gets too hot, the strip bends and cuts off the electric current. No more heating goes on, and the strip starts to cool. When the bimetallic strip is straight again, the circuit is connected, and the heater heats up again.
How long it takes a car heater to warm up depends on the temperature outside. In cold weather the heater can take several minutes to warm up.
mid 70's up to 78 i keep my turtles yellow bellied sliders and map turtles outside in pond have a water heater in water. Plus when not sunny basking light and strip light for them.
sounds like the thermostat is sticking
normally when the heater core becomes plugged you will have n eat and you will notice a definite spike in engine temperature.
The first thing to do is check the radiator, not the overflow tank, to be sure it is full. Next, with the engine warmed up, feel both heater hoses. They should be the same temperature. If not then the heater core is stopped up and will require back flushing. If they are the same temperature then you will most likely have a blend door problem.
as to further go in details on this question water circulation and temperature seems adequate by squeezing the top radiator hose could this have anything to do with heater core clogging up??
the temperature is your mom
A strip heater is a type of electric heater that consists of a flat strip of metal with electrical resistance, used for applications such as heating process tanks, platens, or molds. The strip heater can provide uniform heat distribution over the surface area where it is mounted.
Turn on your vehicle's heater
I hear that it takes a full day to come up to temperature.
