Electric Wall heater options

[Jared Boundy]

Hello BPers, I'm planning some repairs on a rental property that I'm closing on next week. Went for another look this week and realized the downstairs unit doesn't have heat in the bedrooms. So I'm considering these different electric options: 1) cadet wall heaters with built-in fan 2) plug-in panels (VonHaus 450W Wall Mounted Electric Flat Panel Heater - Paintable Slimline Low Energy Eco Ceramic Space Heater (23.5 x 23.5 x 0.4 inches) https://www.amazon.com/dp/B01LZ3NE3E/ref=cm_sw_r_cp_api_H0Q1ybQHE3DNG) 3) convection heater (http://m.homedepot.com/p/Stiebel-Eltron-1000-Watt-120-Volt-Wall-Mounted-Convection-Heater-CNS-100-1-E/206160725) So I'm wondering if you have experience with any of these models or styles. Plug in would require no wiring, just mounting and be less expensive overall. I'm just not sure how well these all really hold up. Electric heat is very affordable here, and tenants will be paying utilities. Thanks in advance for your insights!
