Outdoor water heaters: the ultimate guide to keeping your water warm

Water heaters are an essential component of any modern home, providing us with warm, comforting water for showers, baths, and various household tasks. However, the question of whether a water heater can be placed outside often arises, especially in areas with limited indoor space or unique architectural considerations. This blog post delves into the intricacies of outdoor water heater placement, exploring its feasibility, advantages, drawbacks, and essential considerations.

Types of Outdoor Water Heaters

Before discussing the viability of outdoor water heaters, it’s crucial to understand the different types available:

• Gas Water Heaters: These heaters use natural gas or propane as fuel and are typically more energy-efficient than electric models.
• Electric Water Heaters: These heaters use electricity as their energy source and are generally less expensive to purchase and install than gas heaters.
• Solar Water Heaters: These heaters harness the power of the sun to warm water, making them an environmentally friendly option.

Advantages of Outdoor Water Heaters

• Frees Up Indoor Space: An outdoor water heater can significantly free up valuable indoor space, especially in compact homes or those with limited storage options.
• Improved Indoor Air Quality: Gas water heaters release combustion gases, which can affect indoor air quality. Placing the heater outside eliminates this concern.
• Reduced Noise and Vibration: Outdoor water heaters are typically quieter than indoor models, minimizing noise and vibration levels within the house.
• Easier Maintenance and Repairs: Accessing and servicing an outdoor water heater can be more convenient than doing so in a confined indoor space.

Drawbacks of Outdoor Water Heaters

• Exposure to Elements: Outdoor water heaters are exposed to the elements, including rain, snow, wind, and extreme temperatures, which can impact their performance and lifespan.
• Freezing Risk: In cold climates, outdoor water heaters can freeze and burst, leading to costly repairs or replacements.
• Increased Energy Consumption: Outdoor water heaters may consume more energy to maintain the desired water temperature due to heat loss from exposure to the elements.
• Aesthetic Considerations: An outdoor water heater can potentially detract from the aesthetic appeal of your property, especially if it’s not properly concealed or integrated into the landscape.

Essential Considerations for Outdoor Water Heater Placement

• Climate: The climate in your area will significantly influence the feasibility of an outdoor water heater. Extreme cold or heat can pose challenges.
• Location: Choose a location that is protected from the elements, well-ventilated, and easily accessible for maintenance.
• Insulation: Proper insulation is crucial to minimize heat loss and improve energy efficiency.
• Freeze Protection: In cold climates, consider installing freeze protection devices to prevent the water heater from freezing and bursting.
• Permits and Regulations: Check with your local building codes and regulations to ensure that an outdoor water heater is permitted and meets safety standards.

Can I Install an Outdoor Water Heater Myself?

While it’s possible to install an outdoor water heater yourself, it’s highly recommended to hire a licensed plumber for the following reasons:

• Gas Line Installation: Gas water heaters require proper gas line installation, which should only be performed by qualified professionals.
• Electrical Wiring: Electric water heaters require proper electrical wiring and grounding, which can be hazardous if not done correctly.
• Plumbing Connections: Water heaters must be connected to the water supply and drain system, which requires proper plumbing knowledge and skills.

Tips for Maintaining an Outdoor Water Heater

• Regular Inspections: Inspect your outdoor water heater regularly for any leaks, corrosion, or damage.
• Winterization: In cold climates, drain the water heater and disconnect the gas or electric supply to prevent freezing during winter.
• Insulate Exposed Pipes: Insulate any exposed pipes connected to the water heater to prevent heat loss and freezing.
• Clean the Burner (Gas Heaters): Regularly clean the burner assembly of gas water heaters to ensure efficient combustion and prevent clogging.
• Replace the Anode Rod (Electric Heaters): Replace the anode rod in electric water heaters every 2-3 years to protect the tank from corrosion.

Key Points: Weighing the Pros and Cons

The decision of whether to install an outdoor water heater ultimately depends on your specific needs, climate, and property considerations. By carefully weighing the advantages and drawbacks outlined in this post, you can make an informed decision that meets your requirements.
