Default Time to reach heat in car?

Ok so I have owned may Hondas. Some nicer than others. however that neither here or there, one question that I have always had was. Why do some Hondas start pumping out heat before others?
My 2000 LS starts making heat in a few minutes.
My 1996 LX takes way more time.

Any thoughts? Being up here in the colder state, and with me starting to DD my civic and selling my Integra i would like to get the civic to the condition of the Integra

I had a few egs that the heat sucked. Then in all my EKs the heat would run you out. I hope you can get an answer i would like to know myself

One of the main factors affecting coolant temperature rise is "thermal efficiency". Lets say fuel has 100 units of energy in it. Inside the engine, approximately 30 units is turned into useful work or power, 10 units is lost as friction, 20 units lost as heat in the walls of the combustion chamber, remaining 40 units goes out the tailpipe.

Two identical engines, the one having less energy conversion efficiency warms up faster. For same amount of fuel burned, more power produced,less heat. Less power,more heat.

they'll really be about the same in this respect.

what may not be the same is the mixture of coolant and the condition of the thermostat. also the '96 LX has an adjustable heater valve and blend door that could be missadjusted. i believe the 2000 LX only has adjustment on the heater valve.

i would suggest replacing the coolant in both with the same mixture of fresh coolant, drop in new thermostats and check the adjustment of the heater valve and blend door. then see if they heat up equally.

Lol me too

Okay I would check the cable from the console to the heater valve by the firewall.
On my ek I had a bent rod and the valve just barley moved when I would set the control to full heat. I fixed that by bending it back and boom instant heat.
