Frequently Asked Questions
- Who will install it?
We typically operate as a Business to Business seller. Ordinarily we sell straight to the state certified contractor hired to do the actual plumbing and electrical work. For new homes these are usually the general contractors or home builders. We of course provide whatever (often off-site) assistance we can to these contractors.
- Who provides the plans and permits?
Typically the general contractor or equivalent, although we have many resources to assist them in this task.
- Who provides the maintenance?
We provide servicing for the period agreed in the terms of sale – generally, 2, 5 or 10 years.
- Why isn't the warranty comparable to HVAC or solar with 5, 10, and 25 year coverage?
We have extended warranties and service agreements that provide you with up to ten years of full protection.
- When precisely does warranty commence?
The warranty period starts when the treatment appliance (the NEXtreater) is delivered, installed and turned on for the first time.
- What support does the seller provide?
We work remotely with the builder/certified contractor to, most importantly, get the underground tanks installed correctly. We have many installation documents and resources to make this process easier for the contractor. Sometimes site visits are required and we try to arrange those visits at a time of mutual convenience.
- Who engineers system integration with existing irrigation?
The connection to the existing irrigation system is really quite simple. Our system provides the water pressure needed to run conventional irrigations sprayers and drippers. The specific requirements of your irrigation system should be reviewed by your installing contractor.
- Who engineers system integration with heat exchange capabilities?
Our NEXheater is used the same as any other water heater. We can provide all necessary technical documents but there should be little to no engineering work required. The NEXheater should be installed within thirty fee of the grey water collection tank, and refrigerant lines will need to be installed between the collection tank and the NEXheater.
- What is total system weight? Size? Specs would be helpful.
Sure! See here, here, and here.
- How do I find a factory certified installer if you do not offer installation or entitlement support
We are happy to pair you with an experienced local contractor, when we can. If not, we are happy to work with a state certified contractor of your choosing. Our system qualifies for PACE financing, so a contractor in a PACE network might be a good place to start looking.
- How many gallons per day can the water recycling system process and deliver?
The system is able to treat up to 200 gallons per day, which is more grey water than produced in nearly all homes. The exact amount that you recycle will depend on the size of your family and how you use water. It is typical in many homes to recycle about 100-125 gallons daily.
- How do I know in real time if system water output will be safe in my garden?
The water from the spigot will always be safe. Should the system fault, for whatever reason, the system would go into "bypass" mode and the water would continue to flow into sewer until the issue is addressed. There is also an indicator light on the front panel that would illuminate as well as a beeping sound that would go off until the system is reset (note: the alarm does not go off in evening hours).
- Who monitors system performance?
There is a cellular phone chip in the system that sends us and users a daily report at approximately 6pm PST. It allows us and users to see their system performance from a login portal available via web browser.
- Who would replace the system in the event of failure?
System replacement is included in the warranty and is covered by Nexus eWater.
- How much is shipping typically? Where are you shipping from?
Shipping is usually around $300-$400 in California. We ship system components from either San Diego or LA, depending on the component.
- Can you explain the energy saving component? I know it has something to do with water heating, but not sure exactly how it works.
We capture and reuse the energy that is embedded in the grey water that leaves the home. In other words, we are capturing and reusing energy that has always been treated as waste. We use refrigerant in a heat exchange process to harvest the warmth in our grey water collection tank and transfer it to fresh new water in our water heating appliance, the NEXheater.
- What is the typical ROI for a household that uses ~150 GPD (or ~55,000 annually)? How do you calculate cost savings?
The water, sewer and energy savings of using our system are quite staggering. Many typical suburban homes will see up to 30-40% reduction in the use of potable water, and up to 70% reduction in flows to sewer. With the NEXheater, the energy used to heat water can be cut by up to 80% (around 2,000 kwh annually). The ROI on these savings depend heavily on how water, sewer and energy rates are structured in your area, so each case requires its own analysis.
In areas where drought is chronic, the most tangible payback may be achieved by protecting your home’s landscape. Even during periods when the outdoor use of municipal water is restricted (as has been the case statewide in California), homeowners are able to freely reuse water from the NEXtreater system. Homeowners with lusher landscapes especially value being able to irrigate their landscape as many days as their plants need, unrestricted.
- How many retrofit installations have you provided the product for? Can you tell me in what geographical areas and point me to any that would allow me to look at them?
We focus primarily on new construction so we don't have many retrofit installations. We have a few costumers who have offered to open their home up to serious buyers but we try not to impose on their time needlessly. We usually only make that request when there are large homebuilders or interested policy makers in the immediate area.
- What are the barriers, in your opinion, to getting more systems installed on a retrofit basis?
The two key issues are financing and contractor knowledge. Over time, we hope that more and more contractors will become expert in fitting a system like ours into existing homes. Financing is the other issue that will hopefully be addressed in future years. Rebates, tax credits and creative public financing are not yet available for whole-home solutions like ours.
- What are some of the common failures that I should watch out for?
The biggest concern, especially with a retrofit, is contractor selection. This isn't rocket science, but if the plumbing isn't done correctly you can't honestly expect our system to work correctly, either. It is very important to select tradesmen that are diligent in their work and always looking to learn about new solutions. We have an installation checklist and guidebook for contractors to follow, so the resources for a successful installation are readily available. Make certain you select a contractor who is as interested in our solution as you are!
