Manufacturer Testing

As the manufacturer of End2End Covers, we follow stringent guidelines in production with ongoing inspection compliance with UL labs for energy efficiency [CEC Title 20].  UL Labs [Project Number 4788881992] was completed on 3.17.2019 with a pass/compliance.

CEC Title 20: Per Section 1605.3(g)(6)(B), the normalized standby power (Pnorm), as defined in Table G-3, manufactured on or after June 1, 2019, is not greater than calculated standby power (3.75(V2/3)+40) watts, where V = the fill volume, in gallons.  

Calculated Standby Power (3.75(V2/3) + 40) W: 587.68 
Normalized Standby Power (Pnorm): 566.20 Watts (W) 
Thermal Information:  We all have a general understanding of the insulation R-Rating System.
R-Rating is a measure of how a material resists the flow of heat through that material. There are now many superior, heat-retaining materials available to insulate these days instead of the 50-year-old hot tub style design with thick foam covers.

We have tested the E2E Swim Spa Cover against the R-19 foam cover. The E2E Swim Spa Cover outperformed the R-19 foam cover in climate control test chambers, saving customers daily energy consumption and costs.

The reasons for this, which link directly to the materials used in the designed of the End 2 End Swim Spa Covers®.

  • The E2E Cover’s one-piece system, locks in heat vapor which stops convective heat loss. There are no sections or seams for heat loss like on an outdated conventional hot tub style cover.
  • Air trapped in our multi-layered cover stops conductive heat loss.
  • We use a full layer of barrier to reflect the heat waves back into the water.
  • We use a one-piece closed cell foam cover system, which does not absorb water.

These factors, locking in the heat vapor, air entrapment within the cover, plus reflecting heat waves back to the water is why we outperform the other cover systems.

The E2E Cover® provides consumers energy efficiency, one-person ease of use, and longevity.

From the beginning, I was impressed with how personable and patient Will was on my first call. He took the time to tell me about your company and your extended family business. Next, I was impressed with how well the packing was done when our cover arrived. Please tell your employees that I do not take the quality of their details for granted. I notice all of the care and quality in the stitching of all of the components in your product. It matters ! Finally, we are very happy with the fit and finish of our new cover. It is a great solution, rather than our previous cover that is heavy, cumbersome, and was a big chore to remove and replace. Thanks for the work, the design, and the care you put into your covers.

We have received our swim spa cover and I got to say I love it! Our last cover was a typical “easy” cover lifter. It was a workout to just get in the spa. After 2 years it sagged into the water and became water logged. It was horrible.

After receiving your cover, we followed the directions, and found that I could roll this cover back with 2 fingers. It is amazing! Thank you so much for the product and for it being affordable.

Thank you,

I just wanted to give 2 of your associates a huge thumbs up for there outstanding customer service. In a society with lacking customer priority yours is defiantly an exception. The Sales Manager was able to get me the cover and pushed manufacturing to match my schedule…
The Shipping Manager expedited the shipping and truly cared about how it arrived, following up with me to insure proper delivery. She was also able to have the time to cover all aspect of this cover, even including care and chemical usage. I really enjoyed our interaction.
