The Rheem Commercial Universal Gas Water Heaters, exemplified by the Universal 100 Gal. 199,900 BTU Natural Gas Water Heater, are engineered for seamless integration into constrained retrofit environments while boasting the capacity and capabilities to withstand rigorous commercial demands. Featuring a user-friendly spark-to-pilot electrical ignition system for swift activation, this model caters to diverse hot water applications with its expansive 100 Gal. tank and numerous water connections. Noteworthy for its compact footprint, minimal vent height, and versatile water connections, it stands as an optimal replacement unit. It's imperative to note that this model necessitates a 120-Volt power source. Additionally, its attributes include a space-saving design, facilitated by its short stature and narrow jacket diameters, alongside top, front, and rear water inlets/outlets, ensuring unparalleled installation flexibility. The inclusion of a System Sentinel LED diagnostic system ensures systematic operational verification. Furthermore, its robust tank design, propelled by proprietary steel formulation, patented multi-flue architecture, and dual porcelain enamel coats, yields a superior heat exchanger design. Stainless steel burners, equipped with a raised port configuration, offer durability and facilitate easy maintenance. A low-profile automatic flue damper minimizes overall product height, while a factory-installed full port, full-flow brass drain valve expedites servicing. The direct spark to pilot ignition system optimizes energy efficiency by igniting solely upon heat demand. Corrosion resistance is fortified through a patented anode design incorporating multiple magnesium rods. The unit is pre-installed with CSA/ASME rated T and P relief valves, ensuring safety and compliance. Fully insulated with energy-saving materials, and featuring a gas control system with adjustable thermostat settings, this model offers versatility and efficiency. Moreover, Rheem's universal line provides a range of configurations from 35 Gal. to 100 Gal. models, available in natural gas and liquid propane variants, catering to diverse preferences and requirements.

Comfy and so cute.
Size: One Size, Color: Skyway, Size: One Size, Color: Skyway
This alpaca beanie is just plain cozy. Super soft, comfy, and surprisingly warm. It fits well (the one-size actually works), and it sits nicely without feeling tight or slipping around. I get compliments every time I wear it. Great for cold days, football games, or just when I want something cozy with a little personality.

Very comfortable
Size: One Size, Color: Heather Beech
How I Use It: I’ve been using this beanie for two months. Features that stood out to me: The beanie works great; and I also really liked the knitting; it really holds together well and stays on your head. The material is soft and really keeps your head warm while also breaths, so your head doesn't get too sweaty. My Personal Experience: If I compare this one against the others I’ve used, this one is just plain better. I wasn’t expecting to like the actual cashmere material as much as I do. Pros and Cons: What was good: cashmere soft and warm, great construction, nice color, affordable What was not good: none Durability: After two months, it still does its job the first time every time with no fuss. I can’t really ask for more. Final Thoughts: Overall, it has been good for me and my needs, and I’d buy it again.

Very warm beanie
Size: One Size, Color: Wine, Size: One Size, Color: Wine
This hat is very well made and super warm. I have not worn it while it was snowing or raining, so I’m not sure how well it would hold up if it gets wet. However, I hand washed very gently with some woolite followed the instruction for drying and it dried well. The color is a nice deep plum. It is folded at the bottom and can be adjusted to cover ears or accommodate a longer head shape. The material is as you would expect of cashmere and soft. It still has a good knit structure and doesn’t get stretched out. It’s a little bit of a lint and hair magnet though, so might need a lint roller (especially if you have dogs or cats). I’m just shocked by how warm it keeps my head and ears in temps that are in the teens, even with wind. Very happy with this hat.

super comfy and CASHMERE beanie!
Size: One Size, Color: Black
This beanie is fantastic. The cashmere knit is incredibly soft and warm without being itchy at all. This feels great even after wearing it for long periods. I also really appreciate the minimalist design in that there were no huge brand logos or any crazy graphics on it. The clean silhouette and folded cuff make it easy to pair with just about anything. It’s simple, comfortable, and looks great.

One of the softest things I own
Size: One Size, Color: Black
This Cashmere hat is the softest hat I have ever worn. It is not thick, and it is super stretchy, so fit really is one size fits most. It is incredibly warm. I love natural fibers, as they feel so much better on your skin, and they just work better (I live in a cold climate). This hat has a tiny bottle of nylon/elastsne to make it hold up better and fit better, but it's mostly Cashmere (94%). The wash instructions are simple: hand wash in cold water, roll in a towel, amd block/reshape. Amazon always likes me to comment on value for price on these reviews, and to be honest $98 (the price it was selling for when I ordered it) is rather steep. That is the only reason I didn't give that 5th star. I feel like this hat will last for a decade or more (if one of my kids doesn't steal it), so looking at it that way, the price seems more reasonable, but it is still a lot for a hat. Otherwise, I am absolutely in love with it. It's a little luxury in my winter wardrobe.
