Extended warranties are usually very inexpensive and can save you thousands in the future. Some can even cover extra costs that result, such as cost of food that spoils when your fridge dies. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Appliances can be large, heavy, and expensive and you probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new appliances should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you. Please consult a sales associate about delivery options.

thrilled with new cooktop

Submitted by no nickname - 5/19/2021

It took several weeks to finally get our cooktop, but it was worth the wait. All the burners work great, are easy to use and clean, and we are pleased with the performance. I would highly recommend this product.

New 5 burner gas cook top

Submitted by Mickeyg - 1/22/2021

I have always like Bosch products, from my first Volkwagen to my introduction to their Home products with our current Dishwasher. When it came time to replace our electric cooktop my wife and I decided to convert to a gas cooktop. either of use are enamored with the flat top cook surfaces induction or whatever. The gas cooktop has the look of a more functional cooking surface, everything is on the same plane, the cast iron grates allow easy movement from burner to burner if necessary. After I had the new gas line installed, my son and I did the rest. The installation was relatively easy, your directions were good, careful reading of them answered all our questions. I have done a little cooling on it, my wife does most of the cooking. With the exception of how fast the burners are with gas as opposed to electric was the only hiccup in her getting used to change. I have always thought Bosch products were well made. They are refined in appearance, made well, and look good, they do not look like "run of mill" products. We are pleased with our purchase

Can't use large pots on back burner

Submitted by Scorched stainless top - 7/17/2020

We purchased a Bosch 30" single wall oven (HBL5451US), Bosch OTR Microwave (HMV5052U) and a Bosch 30" Gas Cooktop (NGN8055UC). Microwave and wall oven work great. The Cooktop back burner scorches the stainless when we use a large pot. It takes lots of scrubbing to clean off the scorched marks. Bosch's customer service and our retailer told us to use small pots on the back burner, which is why I would highly recommend not buying this model. Attached are photos of the scorching.

Bosch Gas Cooktop

Submitted by Sylvie - 5/23/2020

The world around us is in disarray, we are in lockdown. How can I feel somewhat distant from all the chaos? First, you must know I am the world's biggest worrier. Sworn testimony will gladly be provided by my three sons. How can a new Bosch Cooktop keep the world fears away from such a person? Let me back-up pre-Pandemic. I have been cooking since I was nine years old and cooking and seeking new recipes is one of my favorite pastimes. So many hours are spent in the kitchen at my stove. For years I have been unhappy with my cooktop it was difficult to keep clean, and the layout was not very efficient, so I finally determined to make a change. it took several months of reviewing options, and with the help of my son who is very into the research of specs of any kind of machine and/or appliance I decided on this Bosch model. My son has many tools and swears by Bosch so he was predisposed. I was so excited with the thought of 5 jets in but 31" of space. This layout is much more workable. The control one has of the jets is amazing, making sauces and stocks then having them be added to another pot is a delight no more wrestling hot pots, can easily slide them over. No matter how one tries there is spatter and spills. With the sealed stainless steel cleanup takes minutes. So while I am absorbed in cooking, the outside world does not share my kitchen. Thank you Bosch for the wonderful design and superior quality. Thanks also to Plessers Appliance, for a great order/delivery customer experience

Cooktop range

Submitted by Ginny - 3/22/2020

I have nevr been happier with this cooktop I have always had gas until we purchased this house and I hated the electic cooktop and so when we remodeled our kitchen this was the one I picked and everyday I tell my husban how much I love it. I do have a drawer underneath it I can use and my installed was able to cut the piece near the box that is the only suggestion that I could make is where the gas connection box is located.

Remodel Replacement 30" Gas Cooktop

Submitted by Kathleen - 4/30/2019

We purchased a suite of Benchmark products for our kitchen remodel of which the 30" Gas Cooktop was one of the purchases. I do love cooking with it so far with its flexible 5 burner format...from warming delicate sauces to speed boiling, this unit packs an impressive amount of versatility into the space of a compact 30" cooktop. I'm very pleased with the purchase.
