Solar Hot Tub Kit

Why a solar hot tub heater?

Because hot tubs, swim spas, and pools are expensive to heat and they use large amounts of electricity or gas. To put it simply, this is the least expensive way to heat your hot tub. The Sunbank Solar Hot Tub Kit produces more than 21,000 BTU per collector on a sunny day and transfers that heat into your tub or spa. In places with high electricity rates that install multiple collector systems, the kit can save you as much as $900 dollars per year.

Simple Installation

The Sunbank Hot Tub Kit allows you to pull excess heat from your Sunbank and put it into your hot tub. It involves

Sunbank Solar Water Heater Mounted on a roof

running pipe from your Sunbank location to a heat exchanger in your hot tub. Since this kit is running potable water through outdoor pipe, it is only suitable for places without hard freezes like coastal California and Hawaii. The kit is especially effective in places where people use their hot tubs year-round. This is because there is 3x more solar radiation in the summer than the winter, so it is best to be able to use the excess heat produced in the summer. This kit serves the dual function of providing overheat protection for the Sunbank in the summer. In the winter, you won’t expect there to be much excess production that isn’t already used by the domestic hot water in the house. This is a simple retrofit and can be installed in one day. Sunbank will supply you with an installation manual that lists the tools you need, and either you or your local handyman can do the installation.

Easily installed on any hot tub

Saves up to $900/yr in electricity costs

Solar Collector

At the heart of the solar hot tub kit is our Sunbank SB-80G system. This system will be mounted on your roof or the ground and connected to your domestic hot water system as that is its primary use. Then a secondary loop is pulled from the system to send heat to your hot tub or pool. This system is rigorously tested and SRCC certified, which makes it eligible for the 30% federal tax credit.

My Hot Tub Isn’t in the Sun

It doesn’t need to be, since you will be pulling heat from the Sunbank that is mounted in the sun.

Swim Spas and Solar Pool Heaters

For swim spas or pools, you will need a different type of system that can produce much more heat and is typically professionally installed. For these types of systems we recommend an array of our Solar Pool Heating Collector. As opposed to typical solar pool collectors that are made of plastic and have a 3-5 year life span before they start leaking, our collectors are made of copper tubing with tempered glass and an aluminum frame. They are robust and made to last for 30+ years. Many people come to us when the plastic collectors on their roof and leaking and have caused their roofs to leak. Our pool collectors are more expensive than plastic pool collectors, but also last much longer. You will want 50-100% of your pool surface area in collectors to adequately heat your pool in the spring and fall, depending on your local climate. Send us a message with the square footage of your pool and where you are located and we can help you with sizing.

 Trustindex verifies that the original source of the review is Google.  I don't write reviews but I have to tell others about James from Sunbank! We got an 80 gallon solar water heater and installed it ourselves. It works very well in Southern California. The installation was a little challenging for us, but James helped every step of the way and was even available to give us advice a full year after we had purchased the unit. He was always quick to respond with a thorough and helpful answer! I wish all businesses were run like Sunbank with people like James!

 Trustindex verifies that the original source of the review is Google.  James, thanks for your continued support.  Our 40 gallon Sunbank water heater is the best. Installed in October of 2021 and we would not trade it. Our life off-grid has worked out well. Bob Billings

 Trustindex verifies that the original source of the review is Google.  My only regret is not getting the Sunbank sooner! I installed the 40 gallon system which has been perfect for 3 people. It has a 1500 watt element to heat the tank when the sun isn't shining and because of the low power demand, we are able to run it completely off-grid. James also took time to answer any questions I had and has been excellent to work with!

 Trustindex verifies that the original source of the review is Google.  James and the team at Sunbank are exceptionally knowledgeable and willing to help.  Pre-sale and post-sale support was wonderful, even to the point of shipping a bunch of extra T-bolts I needed for my unique installation, bolts and shipping all at their cost. I would bot hesitate to work with them again on anything... 10 stars if I could... Mike

 Trustindex verifies that the original source of the review is Google.  Living in the Mojave desert, I've wanted to "go solar" for our home's energy needs for a long time (I like free stuff). We put in a solar electric system in 2004, which has long since paid for itself, and bought a plug-in hybrid car to use our "free gas" several years ago.  I finally decided to heat our water with the sun, and after looking at a number of systems, I chose SunBank Solar based on it having no moving parts (I don't like to fix stuff). I mounted it on the ground since we have no shading on the other side of the wall from our old electric water heater, which made the plumbing pretty simple. For overheating protection in the desert, I painted half of each heating tube with reflective silver paint as James recommended (see photo on right), so when we leave on vacation I just rotate each tube to prevent heat absorption, turning the system off. The instructions provided, along with some how-to videos on youtube for using pex tubing, allowed me to get it all put together with no prior plumbing experience.  James was an invaluable resource when I had questions, which was often!  The system has now been running for over a month, quietly generating all the hot water we need!  I highly recommend not only the system but the company for the high quality materials and excellent product support!

 Trustindex verifies that the original source of the review is Google.  Installed the Sunbank 40 water heater 12/2019. We didn’t install the controller until 8/2020 in case we needed it in the coming winter, but still haven’t needed supplemental heat in south Florida as of 4/2021.  Love this thing! Works great for the 2 of us in our small (1000 sq ft) home.  So glad we installed it.  Company was very responsive to all questions prior to ordering through install.  Highly recommend!

 Trustindex verifies that the original source of the review is Google.  I rarely write reviews; however, I am very happy and impressed with the Sunbank solar hot water heater. It appears to be made from top quality material. I was replacing a Solarhart which was not a stainless steel tank and the heat exchanger developed a leak. I started with a 40-gallon system and installed it myself. I’m very handy with DIY projects. The Instructions online were clear, and James was very helpful with any of the questions I had. Being in Phoenix I thought a 40-gallon system would be enough. Once Witter arrived, I realized that I use more hot water than I thought and wanted to have 100% solar hot water. Thus, I installed a second 40-gallon system to boost my capacity to 80. I also install a couple of radiators to heat the master bath and home office allowing me to heater those room in the fall, winter, and spring with excess hot water. In summary, I am very happy and give Sunbank 5 stars for quality and service.

 Trustindex verifies that the original source of the review is Google.  I installed the Sunbank and the water temp went from 50F to 101F in 4 hours the 1st day.  By the 3rd day I was up to 160F.  It only loses approx 5 degrees overnight.  It is awesome!  James at Sunbank is one of the best support guys I've dealt with.  Definitely recommend buying this for solar hot water.

 Trustindex verifies that the original source of the review is Google.  Our family purchased a 40 Gallon Sunbank Solar Water Heater just over a year ago and we are VERY pleased with its performance, ease of installation, and energy savings!  We have it installed on top of our spring house roof, located about 125 ft. away from our house.  When combined with the Federal Tax Credit and the savings associated with the solar offset of electrical usage for heating water, this Sunbank system quickly pays for itself and is a great investment.  I was able to install the system on my own and it has performed flawlessly during its first year of use.  James at Sunbank Solar has been more than helpful in responding to any questions I have, even after the initial purchase, which says a lot!  I would recommend the Sunbank Solar Water Heater to anyone wanting to save money and reduce our environmental impact!

 Trustindex verifies that the original source of the review is Google.  I recently installed two 40 gallon Sunbank solar water heaters - one on my garage and one on my ADU. They have been awesome! Water is super hot and now I don't have any qualms washing my laundry with warm, solar heated water! I have wanted a Sunbank system for almost four years now, and James has patiently helped me through the process. I used my local solar panel installer to get the job done. Took 3 days to fully install (I did need some reinforcement for 2x4 rafters) and inspection was quick and easy. James steered me to a great structural engineer to get what I needed for City Planning. It feels great to have gotten rid of my natural (fracked) gas water heaters! And the 30% tax credit, along with the California Solar Initiative rebate, really makes it affordable.
