Reply to comment by sumpdiddlyump_ in New 8000 series Metro trains will have heated floors and charging outlets by Yaratam

i always appreciate good snark about metro, but I think studies have shown it's the most efficient way of heating homes. idk if that would be true of train cars though

Interesting! It just seems like needless complexity to me, but if it reduces costs, then that’s obviously a positive.

It may be counter intuitive, but it will actually reduce complexity. Wires or coils that get hot when you run power through them in the floor have a lot less that can go wrong than a full blown HVAC coolant loop system.

But you’ll still need the HVAC anyway so now you have two things that can break

Or you can now simplify the HVAC system to only need to perform one task instead of try to do two counter tasks.

Air source heat pumps can deliver 3x the energy they consume, can be reversed to do heating or cooling, and are growing in popularity in residential systems.

If they're going to have an AC system already, why not this?

I assume there were numerous planning meetings, an analysis of alternatives, cost estimates, and many more things that we were not privy to here that factored into the decision.

It's WMATA. Meaning somebody high up is friends/family with someone who owns a company that installs/sells these systems and gave them the contact. Or just straight up took a bribe for it.

Don't worry, I'm sure it will be prone to failure.
