Both good products, here is something to consider- Hotter water in the tubing means less overall system efficiency. In addition the hotter water will cause you to notice hot/cold spots across the flooring surface. A modulating condensing boiler leaves the condensing mode around 155-160 degrees F meaning it's efficiency is dropped to the mid-eighties in efficiency and your not getting the system you paid for. Regardless of tubing, the key to an efficient radiant panel/floor system is the install. Also the lower water design temp that can be achieved adds comfort, efficiency and less noise. No matter what tubing, a medium to help spread the heat from the tubing and in your case if your going with staple up, the more plates the better. I would ask your radiant guy to design your system so that on the coldest expected day, the water to the tubing does not exceed 130.

It is interesting the different perspectives that we all have re: the feeling we wish to have for a room. Still since it is a master I wonder if what you are really missing is a sense of "warmth" to the room vs the natural light. The white in a north facing dark room would be pretty dismal and not feel warm at all. I think with proper lighting and color you can create the "mood" you want with any color that speaks to you. Every single person who sees my mstr bedroom asks how I came up with the color after saying they love it but are certain they would never choose it. DH was sure he wouldn't like it but loves it too. I agree that on the chip it is questionable but in the room it creates a beautiful tranquil feeling that is warm and light at the same time. It mixes beautifully with silver tones and that adds a lot more light to the room - silver plated drapery rods, white murano glass pendants with silver leafing beside the bed over simple mirrored night stands - all help create the mood. It is an east facing room with full sliding doors that are covered with heavy silk - also light reflecting - drapes to allow sleep past 5:30 in the summer months! Light is not really an issue but as someone above mentioned we are in the room mostly at night and I don't want to feel like I am in a dark cave reading in bed at night. Anyway, I would recommend looking through inspiration photos of room here and on HGTV - figure out which ones create the mood you want for your room - avoiding any that seem require full natural light - and incorporate the colors into your room. Think about everything in the room and how it contributes to the feeling - bedding can make a huge difference. So many of the new designs incorporate silks and other reflective materials that can add to the warmth and light in the room.

Install glass shelves in the niche with and LED can light in the ceiling of it to light up a collection of something pretty, interesting or unusual. This is is a very awkward arrangement with the sectional jammed in the corner and into the windows. With the larger TV centered on its wall, you'll need to pull the sofa out to float centered with the TV wall and the fireplace. You might try its matching hassock/footstool pushed into that window corner with a pile of colorful pillows to match a new rug. That would make a nice reading spot or a corner lounge for the teen who wants to be on their phone or other device. Your rug is much too small for that big sofa. That's where you will get the "homely & warm" color/pattern. Once you get the furniture arranged, use painter's tape on the floor and tape out a "virtual" rug that slips under the front 1/3 of the sofa seats and extends past the ends of it by a foot or more. Keep it at least 12" from the hearth. If your measurement is not a standard size, then go up a size if you can so you don't get a skimpy one. As for empty space around the sofa, try a sofa or game table behind the short side of it. If you're not installing draperies, hang art between the windows. You can put casegoods under the art too. The art above the mantel is too large; keep it mantel art within the width of the firebox below it.

You have nice light golden red wood floors, a big bay window with golden trim, white walls. The problems are the furnishings. You need to replace the oversized sofa and two chairs. Sorry, as someone said, they're sucking light and space from the room. You don't necessarily have to go white or cream if you have kids. Consider a golden camel leather sofa with a couple of comfortable narrow profile recliner chairs for TV watching. The chairs are too fussy for your style, though you should go for something up on legs. Pair of recliner chairs for TV watching: Rug Console table along back wall near front door. Add a lamp. Add a long vertical mirror by the front door
