In a tiny house, space is limited, so choosing the right water heater is crucial. Whether you’re looking for a compact unit to provide hot water on demand or a more traditional system, there are several types of water heaters for tiny houses that can meet your needs. From tankless water heaters to solar-powered systems, here’s an overview of the best options for tiny home living.

Tankless Water Heaters: Efficient and Space-Saving

One of the most popular choices for tiny houses is the tankless water heater. Unlike traditional tank water heaters, which store hot water in a tank, tankless models heat water on demand as it passes through the unit. This eliminates the need for bulky tanks, making tankless water heaters perfect for tiny homes where space is at a premium.

• Propane tankless water heaters are especially favored for off-grid setups. They use propane tanks to heat water quickly and efficiently. Some propane models offer freeze protection, making them ideal for use in cold climates.
• Electric models are another option for tiny homes connected to the grid or using solar power. These units use almost no electricity when not in use and provide endless hot water whenever you need it.

Key Benefits:

• Space-saving: No large tank required.
• Energy-efficient: Only heats water as needed.
• Variety of power sources: Options for propane, natural gas, or electricity.

Traditional Tank Water Heaters: Reliable, but Bulkier

Though not as compact as tankless units, traditional hot water heaters with tanks are still an option for tiny houses, especially for those who prefer storing heated water in advance. A tank water heater holds a set amount of water (usually between 20 to 50 gallons), ensuring hot water is always available for everyday use.

• Propane water heaters are available in tank forms as well, often used in tiny homes equipped with propane appliances.
• Electric water heaters also come in tank versions, suitable for those with access to solar panels or an electric power grid.

However, keep in mind that tank water heaters can take up more floor space and may be less energy-efficient compared to tankless models.

Propane RV Water Heaters: Perfect for Off-Grid Living

Many tiny house owners opt for propane RV water heaters, which are designed for small living spaces like tiny homes and RVs. These heaters are compact, efficient, and work well in off-grid settings. They run on propane tanks and can easily be installed indoors with vent tube systems to release exhaust gases.

• Direct vent style heaters are recommended for indoor units, ensuring proper ventilation and safety.

Propane RV water heaters are great for tiny homeowners who want hot water without relying on electricity.

Solar Water Heaters: Eco-Friendly but Dependent on Climate

For tiny homeowners focused on sustainable living, solar-powered water heaters are an excellent option. These systems use solar panels to heat water, making them eco-friendly and cost-efficient in the long run.

However, the performance of solar water heaters can depend heavily on your location and climate. In areas with less sunlight or cold climates, a backup system (like a propane or electric heater) may be necessary.

Key Benefits:

• Eco-friendly: Uses renewable solar power.
• Low operating costs: Once installed, the solar system is virtually free to run.
• Great for off-grid living: Ideal for those with solar panels already installed.

Other Space-Saving Water Heater Options

• Low flow showerheads: Pairing a low flow shower head with any water heater can help conserve hot water, particularly in tiny homes with limited hot water availability.
• Portable water heaters: Ideal for temporary showers or seasonal use, these compact units can be hooked up to a propane tank for on-demand heating.
• Precision Temp: A brand known for producing propane RV water heaters and other compact models designed for tiny houses. Their products provide endless hot water while conserving energy.

Choosing the Right Water Heater for Your Tiny House

When deciding on the best water heater for your tiny house, consider factors like available space, energy source, and whether you’re living off-grid or connected to utilities. Tankless water heaters are highly recommended for their space-saving design and efficiency, while propane or solar-powered options offer versatility for more remote locations.

Whether you need a system that provides hot water on demand, or one that can integrate into your solar power system, there’s a solution for every tiny home.

Frequently Asked Questions – FAQ
