Are you familiar with a heater I bought for my renovation? I purchased the Smart Envi 220v Hardwired Electric Panel Wall Heater - 500 Watts - 4th Gen (SE5022D) from the Texas company that produces it. It can be programmed from a smart phone to regulate temperature preferences.
Tim, thank you for sharing the first video of the Runtal heaters. What caught my eye on this basement remodel is the make up of the insulation and furring at the outside wall. It looks like a double 2 x 4 stud wall furring with fiberglass insulation in the cavity closest to the exterior covered by plastic sheeting. Then it looks like there’s a foam board that’s added over that framing. Will you please share the exact makeup of this furring and insulation? Including how far from the concrete block wall it is, etc. Thanks in advance. No rush needed for the reply.
