Compact, Efficient, and On-Demand Hot Water for Your Cabin or Home.
The Camplux CA422 Indoor Tankless Water Heater offers a revolutionary approach to home water heating, providing an endless supply of hot water with exceptional efficiency and a compact design. Ideal for cabins, small homes, or as a reliable backup, this unit delivers powerful performance while saving valuable space.
Key Features & Benefits:
- Space-Saving & High Performance: At just 1/4 the size of a conventional 50-gallon tank water heater, this unit delivers approximately 4.0 GPM of hot water with a robust 102,000 BTU output, easily meeting the hot water demands of both a bathroom and kitchen simultaneously. Its highly integrated components also enhance safety by preventing water pressure surges, often eliminating the need for an expansion tank.
- Fast & Endless Hot Water Supply: Experience instant hot water as the oxygen-free copper heat exchanger rapidly heats water to a maximum of 140°F (60°C) in just 2 seconds. Enjoy continuous hot water at approximately 4.0 GPM for up to 40 minutes, providing nearly 160 gallons of hot water without the wait associated with traditional tank heaters.
- Steady, Comfortable Temperature Control: Benefit from precise temperature management with a chip that calculates and controls heating power 1000 times per second, ensuring water temperature remains within a tight ±2°F (±1.1°C) difference. The modern design, featuring a unique gray glassy front panel and LED touchscreen, allows for easy and accurate temperature control.
- High Compatibility & Easy Installation: Designed for broad compatibility, this unit can replace most tank water heaters, often utilizing existing exhaust vents, water, and gas pipes with only a simple re-layout. Its compact size facilitates easy installation even in new constructions. We highly recommend all installations adhere to local building and plumbing codes and are performed by licensed professionals.
- Durable & Long Lasting: CSA certified for use in both the USA and Canada, ensuring superior safety and durability. Built with the world's most advanced technology, Camplux provides a 3-year warranty on the heat exchanger and a 1-year warranty on all other parts.

I almost NEVER leave a 5 star review. They are reserved in my world for places that do something EXCEPTIONAL. Kyle A. And the crew at Cabin Depot are a group of those exceptional people. They patiently worked with us as we developed our off grid setup and provided not only fair prices, but wonderful follow-up with my installation and operational questions as our system came together. Thank you and we look forward to a continued relationship.
I’ve taught customer service to many organizations in my professional career. I’m now long retired and still find excellent customer service difficult to come by!
The Cabin Depot, and especially Kyle Aubin, are exceptional examples of customer support and service!! My only regret was not reaching out sooner!
I would have saved myself significant time, lessened aggravation, and a happier installation of my EG46000XP and generator backup.
Lyle’s patience and response time, his pleasantness and professionalism, will contribute significantly to me looking first to them for future sales and service!
We ordered our PV panel, battery bank and inverter set up in September 2024. There were a number of hurdles to get over and many times we worried we were not going to accomplish our dream of greater self sufficiency.
With the owner of Cabin Depot involved, we have received strong support in resolving our issues and have now got an inverter, lithium battery and PV set up which has taken us from using a generator and having periodic power, to uninterrupted power supply allowing us to run a number of electrical devices continuously, including our well pump and a modem.
We look forward to a continued relationship with Cabin Depot and thank them for helping us to get over the finish line with what has been a daunting project.
Recently added a EG4 LL battery to my existing system.
Cabin Depot was great to deal with, shipping was around a week., which is pretty good considering it was shipped across Canada.
Only delayed by 1 day but that was a UPS thing.
This battery was added to 3 existing EG4 Lifepower batteries.
Everything worked no issues at all., only thing was the communication ports are in different locations and the supplied cables are too short to reach,
No big deal.
All in all very happy and would order again
I was so impressed last year when I called from Alberta - searching for the right equipment (hot water on demand and propane heater… and I have to say I am impressed again - today was just a special order thermocouple to have as a spare - the service you provided for a 35 dollar part was above and beyond.
I purchased a drolet myriad III wood stove from cabin depot. Customer service was great, delivery was fast and they replied to all of my questions very quickly. When I received the wood stove I unboxed it while the driver was here (as suggested by the company). Everything was perfect and the driver from midland transportation was very accommodating.
A+ thank you very much!
Propane stove came on time in perfect condition, super easy install, helpful customer service, very competitive price!! Just a good company. We will be buying more off grid supplies from this fantastic group of professionals!!
