I'm trying to buy new programmable thermostats for my electic
baseboards.
Problem is, existing (mechanical Honeywell line) thermostats are rated
22amps but most of the programmable ones I see are rated around 16-20
amps.

Did someone just install some overkill thermostats or do I really need
ones rated at 22amps?

I tried researching heaters that I have but couldn't find any info.
