Radiant Panel?

Cyclist77

Is there such a thing as a radiant wall panel similar to a radiator? Our mud room just doesn't get enough btu's. But I have access underneath to run a supply and return.

My "idea" is something like a wall mounted radiator but using my .loop.

Thoughts?

Do you mean something like a Radson or Vasco or Runtle?

What is your current heating system using for radiators?

A gravity heating system that is converted to a forced hot water system. (meaning it has a circulator pump now) that is heating your home comfortably, is balanced, and does not use too much fuel should be left alone. Adding a different type of radiator mixed in with the rest of the gravity system often times does not result in the desired outcome.

Your best bet is to make a separate zone with a home run from the radiator to the boiler room with PEX tubing (with oxygen barrier) and set that up with a different pump and perhaps a thermostatic radiator valve on that panel radiator. That way the existing pump that is operating the rest of the home efficiently, will not be interfered with. A European wall panel radiator will require a different GPM flow rate than a Copper pipe with aluminum Fin baseboard radiator and that wull be different that a cast iron standing radiator. When you mix and match the different radiators on the same thermostat and the same main piping arrangement, you will never get it right.

You mean like this?

Currently staple up system. Not going to open the wall and run a loop back and forth. Something surface mounted.

Ed,that is my thought a separate pump for that panel. Planning now for spring/summer projects!

Retrofit radiant walks are often just the lower 3’ of wall with maybe a wood wainscot over the transfer plates No need to open the existing wall.

Bob, would I be disappointed if I just used a panel radiator?

Panel rads with TRVs are a very nice way to go. A TRV is a simple, non electric proportional control. Paired with a delta P circ it is a great option.

The term "radiant panel" is slightly confusing. This refers to loops of radiant tubing that can be in a floor, a ceiling, a wall, a wainscoating, etc. A "panel radiator" is a very specific, other "thing". It is a flat metal radiator of European design and mfg., (or American, Runtal). It hangs on and resides close to the walls. Radiant panels are optimal and can usually use lower, circulating water temperatures. Panel radiators are a close "second. best" with regards to lower water temps.

So is the correct term "panel radiator "?

I have several panel rads by myson in my house and I love them. If you have a single temperature system currently you can size it for your current supply temperature so it works best without having to change the original system

Because this is for such a small space as a mudroom, I would avoid touching the main system. I would go for a small electric wall heater. I recommend the "Envi Wall Heater." It is 500 watts and a standard 120V plug-in heater. Used as supplemental heating, it will bump this rooms BTU up enough. I have one mounted in my upstairs hall which never got its own cast iron rad (old builders guides I've read from the early 20th century stated one should have been installed in the upstairs hallway).

With the thermostat engaged, costs come to $0.04 per hour with my local electric utility rates ($.161 per kwh). Even if I leave it on full blast 24/7, costs come to $0.07 per hour. I have all my supplemental heaters connected to smart plugs with energy monitoring so I can see exact cost.

Is that some type of Euro 230V wall plug adapter? Or a wifi module?

That is the smart WiFi plug it plugs into. Here’s how it looks in the app.
