Imagine stepping into a warm shower on a chilly morning, only to have the water turn icy cold because someone turned on a faucet elsewhere. This frustrating scenario is all too common with traditional tank water heaters. If you are seeking a solution that delivers consistent, on-demand hot water without the bulk of a storage tank, a point of use water heater might be the answer. This guide focuses on the Westinghouse Tankless Water Heater Propane, an outdoor model designed to provide endless hot water for your whole home while saving space and energy. Whether you are upgrading an existing system or building new, we help you evaluate if this propane tankless unit meets your needs.
Buying Guide
Flow Rate and Fixture Support
One of the first things to consider when choosing a point of use water heater is its flow rate, measured in gallons per minute (GPM). The Westinghouse model delivers up to 8.1 GPM, which comfortably supports three to five fixtures simultaneously. This means you can run a shower, a dishwasher, and a sink all at once without a drop in temperature. For most households, this capacity is more than adequate, but always assess your peak usage to ensure the unit can handle your demands.

Temperature Stability
Nobody enjoys sudden temperature swings in the middle of a shower. The Westinghouse unit features intelligent self-modulating technology that maintains outlet temperature within ±1°F. This real-time adjustment matches gas input with water flow, eliminating those hot-cold fluctuations. The included wired digital controller allows you to set temperatures from 95°F to 158°F from multiple points around the house, giving you precise control over your comfort.

Energy Efficiency and Operating Costs
Unlike traditional tank heaters that constantly heat and reheat water, the Westinghouse tankless water heater heats water only when needed. This on-demand approach reduces standby energy loss, which can lower your utility bills over time. The compact wall-mounted design also saves valuable indoor space, making it ideal for homes where square footage is at a premium.

Durability and Outdoor Readiness
Since the Westinghouse unit is designed for outdoor installation, it must withstand various weather conditions. It is CSA-certified for safety and includes integrated freeze protection, a variable-speed combustion fan, and durable internal components. These features ensure reliable performance in changing climates, from cold winters to humid summers. The unit also comes with a 2-year limited warranty on the complete unit and an extended 5-year warranty on the heat exchanger, providing peace of mind for your investment.

Frequently Asked Questions
What is a point of use water heater?
A point of use water heater is a compact unit installed near where hot water is needed, such as under a sink or outside for outdoor use. It heats water on demand, eliminating the need for a large storage tank and reducing energy waste. The Westinghouse propane model is one example that serves multiple fixtures from a single outdoor location.
How does a propane tankless water heater work?
When you turn on a hot water tap, cold water flows through the unit and is heated by a propane-powered burner. The system activates only when water is demanded, so no energy is wasted keeping a tank hot. The Westinghouse model uses self-modulating technology to maintain a consistent temperature, even when multiple fixtures are in use.
Is the Westinghouse tankless water heater easy to install?
Installation requires standard 3/4″ NPT residential plumbing and a 120V AC power source. Because it is designed for outdoor use, you do not need indoor venting, which simplifies the process. However, professional installation is recommended to ensure proper gas connections and compliance with local codes.
Can a point of use water heater save money on energy bills?
Yes, because tankless water heaters only heat water when needed, they avoid standby heat loss common with storage tank models. Over time, this can lead to noticeable savings on your propane or gas bills. The Westinghouse unit’s energy-efficient design helps reduce operating costs without sacrificing performance.
