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

This is a simple retrofit and can be installed in one day. You will need to mount the collector and panel, assemble the plumbing, and connect the panel to the solar powered pump . 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.

Solar Collector

At the heart of the solar hot tub kit is our flat plate solar collector, meant for high temperature applications. The Sunbank flat plate collector is an industry leader in performance, cost, and durability. It is rigorously tested and SRCC certified. As opposed to typical solar pool collectors that are made of LDPE 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.

My Hot Tub Isn’t in the Sun

No problem! Not everyone will be able to mount the solar collector right next to the hot tub. You might want to mount the collector on your roof, a nearby fence, or the pergola over the hot tub. Let us know and we can help you get the correct mounting hardware.

Number of Collectors for Hot Tubs, Swim Spas, and Solar Pool Heaters

How many collectors you can use depends on a number of factors, including: your local climate, collector shading, how well insulated your tub is, the size of your tub, how often you use your tub, whether or not you use jets (they quickly disperse heat), etc. There are two methods to see how big of a system you need. We go over the sizing on our How the Solar Hot Tub Kit Works page.

Larger bodies of water require more heat and custom sizing. To help us help you, send us an email and tell us how large your pool or swim spa is (length x width), where you’re located, and what temperature you like to keep your water. We’ll run the numbers and suggest a system that will save you lots on that heating bill.
