Choosing Your Outdoor Propane Tankless Water Heater: A Smart Guide
Thinking about getting an outdoor propane tankless water heater? This guide will help you pick the best one for your needs. These heaters are super handy for outdoor showers, pools, and even remote cabins. They heat water only when you need it, saving energy and space.
Why Choose a Tankless Water Heater?
- Endless Hot Water: You won’t run out of hot water like with traditional tank heaters.
- Energy Savings: They only heat water as you use it, which saves propane.
- Compact Size: They are much smaller than bulky tank heaters.
- Easy Installation: Many are designed for simple setup outdoors.
Key Features to Look For
1. GPM (Gallons Per Minute) Flow Rate
This tells you how much hot water the heater can make at once. Think about how many things you might need hot water for at the same time. A higher GPM means more hot water for multiple uses.
2. Temperature Rise
This is how much the heater can raise the water temperature. If you have very cold incoming water, you’ll need a heater with a good temperature rise capability to get your water as hot as you like it.
3. Ignition Type
Most outdoor tankless heaters use electronic ignition. This is reliable and easy to use. Some might have pilot lights, but electronic ignition is generally better.
4. Safety Features
Look for built-in safety systems. These include things like flame failure protection, overheating protection, and anti-freeze protection. These features keep you and the heater safe.
5. Durability and Weather Resistance
Since it’s an outdoor unit, it needs to withstand the elements. Check for materials that resist rust and corrosion.
Important Materials
- Stainless Steel: This is a great material for the heat exchanger and outer casing. It’s strong and resists rust.
- Copper: Copper pipes are excellent for heating water quickly and efficiently.
- Aluminum: Some parts might use aluminum for lightness and heat transfer.
Factors That Improve or Reduce Quality
Quality Boosters:
- Good brand reputation.
- High-quality internal components.
- Excellent customer reviews.
- Long warranty period.
Quality Reducers:
- Cheap, flimsy plastic parts.
- Poorly written instructions.
- Short or no warranty.
- Many negative customer complaints.

Frequently Asked Questions (FAQ)
Q: How much propane does a tankless water heater use?
A: They are very efficient. They only use propane when you turn on the hot water. This saves a lot of fuel compared to tank heaters that keep water hot all the time.
Q: Do I need a professional to install it?
A: Many models are designed for DIY installation. However, you must follow all safety instructions carefully. For gas lines and ventilation, a professional might be recommended to ensure everything is safe and up to code.
Q: Can I use it in freezing temperatures?
A: Some models have anti-freeze features. If you live in a cold climate, make sure to choose a heater with this protection or plan to drain it when not in use during winter.
Q: How long do these heaters last?
A: With proper maintenance, they can last 15-20 years. This is often longer than traditional tank water heaters.
Q: What size do I need?
A: Consider how many gallons per minute (GPM) you need. For a single shower, 1-2 GPM might be enough. For multiple uses at once, you’ll need a higher GPM.
