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.

Great product for a great price

Submitted by jmoschetti45 - 3/28/2019

It had good reviews so I figured Id give it a try. Being a plumber Ive installed many tankless water heaters over the years but never one of these. Its been up and running for about 6 months now. Been keeping up with hot water demand without a struggle. Great product

This is one quality water heater

Submitted by Homerkw - 10/16/2018

Ive had to send off for about 3 weeks I installed it myself I do have a background in plumbing so that wasnt a problem the ease of installing this was amazing I thought it would be a lot harder than what it was if a person doesnt have the background you do need to get a plumber to do it instructions were pretty clear what Ive been looking for a while at different units and come across the Electrolux and Im so glad I did the quality compared to some of the other ones Ive seen is amazing and it works so well I am really happy with it I needed something that I didnt have to worry about my basement with a traditional hot water heater and it gave me a lot more room in my shop area so I am very very happy with the Electrolux hot water heater and its good looking too

Fantastic Heater

Submitted by willwheel4food - 5/18/2018

My first tankless and I love it Small package very quiet and no problem filling hot tub at full temp. Install is a breeze but be certain to plan all of your piping before you begin because their is a lot of terminations in the bottom of this thing. I had to increase the size of my gas line to handle the extra btu load. Also if adding to an excessively large water system or PVC/PEX you made need to add a check valve on the cold water intake to prevent the unit from false starting upon cold water usage due to the flexibility of your pipes.

Unlimited hot water

Submitted by Pawl - 4/22/2018

I decided on this unit primarily on cost. Local store had a online special to good to pass up. I am a licenced plumber and have installed all the major brands. It did not have all the features as the others such as internal pump and built in buffer tank. You can add these if wanted but not worth the extra cost and labor. I do believe these units are made my Noritz which have a excellent reputation in the on demand market. Overall a great product a few changes to keep up with the competition and this would be a top contender. I do recommend install do be done by someone with experience as it is a little labor intensive vs a tank type unit. Overall b+ for features and A+ for value. You will mot be disappointed in the product if you do your homework and understand the pros and cons of on demand heatets.

Go Tankless

Submitted by Abadegg72 - 2/3/2018

This was the first tankless water heater that I have installed. I know the technology has been out there for a number of years but I finally decided to take the plunge. Unfortunately I am learning that Electrolux is no longer making these units however they continue to stand behind their product the day it is installed. Installation instructions were reasonable given the complexity of these systems. Probably not a project for the newbie DIY type but overall an excellent solution to an endless supply of water with a quick return on investment consdering the energy you will save versus standard hot water heaters with storage tanks. Ive read in forum groups that others have witnessed a 50 savings on their gas bills. I would highly recommend this unit to anyone looking to convert to tankless. I would encorage Electrolux to reconsider bring this product line back.
