Your Guide to Outdoor Tankless Water Heaters (Natural Gas)
Thinking about getting an outdoor tankless water heater that runs on natural gas? These heaters are a smart choice for many homes. They heat water only when you need it, saving energy and space. This guide will help you pick the right one.
Why Choose an Outdoor Tankless Heater?
Outdoor tankless water heaters are great because they don’t take up space inside your house. They are also very efficient. They use natural gas, which is usually cheaper than electricity.
Key Features to Look For
When you shop, keep these important features in mind:
1. Flow Rate
- This tells you how much hot water the heater can provide at once.
- Think about how many faucets or showers you might use at the same time.
- A higher flow rate means more hot water for everyone.
- Look for gallons per minute (GPM). A typical home might need 5-10 GPM.
2. Energy Factor (EF) or Uniform Energy Factor (UEF)
- This number shows how efficient the heater is.
- A higher EF or UEF means it uses less energy to heat water.
- Look for models with an EF of 0.80 or higher.
3. Ignition Type
- Most modern units use electronic ignition. This is reliable.
- Some older models might use a pilot light, which is always on. Electronic ignition saves more energy.
4. Temperature Control
- You want to be able to set the exact hot water temperature you like.
- Digital controls make this easy.
5. Venting Options
- Outdoor units need a way to vent out exhaust gases.
- Make sure the model you choose has venting that works for your home’s setup. Some use direct venting through a wall.
Important Materials
The materials used in your water heater affect how long it lasts and how well it works.
- Stainless Steel Heat Exchanger: This is a top choice. Stainless steel resists rust and corrosion. It helps the heater last a long time.
- Copper Heat Exchanger: Copper heats water very fast. It’s a good material, but stainless steel is often preferred for its durability.
- Durable Casing: The outside of the heater should be made of strong, weather-resistant metal. This protects the inner parts from rain, snow, and sun.
Factors That Improve or Reduce Quality
Several things can make a water heater better or worse.
Quality Boosters:
- Good Brand Reputation: Choose brands known for making reliable appliances.
- Long Warranty: A longer warranty, especially on the heat exchanger, shows the manufacturer trusts their product.
- Easy Maintenance: Some heaters are designed for simpler cleaning and part replacement.
Quality Reducers:
- Low-Quality Components: Cheap parts can break down faster.
- Poor Insulation: This can lead to energy loss.
- Difficult Installation: If it’s hard to install, it might also be hard to fix.
User Experience and Use Cases
An outdoor tankless water heater can change how you use hot water.
- Endless Hot Water: You won’t run out of hot water during busy times, like when multiple people shower.
- Space Saving: It frees up indoor space. This is great for smaller homes or if you want extra storage.
- Energy Savings: Because it only heats water when needed, you save money on your gas bills.
- Outdoor Activities: Some people use them for outdoor showers, pools, or hot tubs.
Common Use Cases:
- Whole-Home Hot Water: Providing hot water for sinks, showers, and appliances throughout the house.
- Second Homes or Cabins: A great option where you don’t need a large indoor unit.
- Pool or Hot Tub Heating: Some models are powerful enough to heat outdoor water features.
