Specifications side by side

Choosing the Right WINTEMP Model

1. Check Your Electrical Capacity

   Every WINTEMP model on this list requires 240V power. You must verify your home’s electrical panel can support the specific wattage of your chosen unit. The 13.8kW model demands the most power, while the 7kW and 11kW units require less. Incorrect voltage leads to poor performance or tripped breakers. Match your existing circuit capacity to the heater’s requirements before purchase to ensure safe and reliable operation.

2. Match Capacity to Usage

   Select a unit based on the number of fixtures you need to serve simultaneously. The 13.8kW model is best for single bathroom homes where you need consistent flow for showers and sinks. Smaller units like the 7kW are designed for single sink applications only. Choosing a higher capacity than needed wastes energy, while a lower capacity leaves you without hot water during peak use times.

3. Consider Installation Space

   Measure your installation area carefully, as dimensions vary between models. The 7kW unit is notably compact, weighing just 8.4 pounds with a small footprint. The 13.8kW model is slightly larger but still fits tight spaces. Ensure you have enough clearance for maintenance access. Verify that the width, height, and length of the unit fit your designated wall space without obstructing other utilities or piping.

4. Plan for Point-of-Use

   Determine if you need a central unit or a point-of-use solution. The 7kW and 11kW models are ideal for single fixtures, such as a bathroom sink or kitchen tap. They reduce wait times by heating water close to the source. The 13.8kW unit serves a broader area but may not be necessary for isolated taps. Align the heater’s output with your specific plumbing layout to maximize efficiency.

5. Verify Wattage Requirements

   Review the specific wattage rating for each model to ensure compatibility with your electrical system. The 13.8kW and 11kW models offer higher output for faster heating, while the 7kW model provides lower output. Higher wattage correlates with greater hot water flow rates. Confirm that your wiring and breakers can handle the continuous load. Proper wattage selection prevents electrical issues and ensures the heater performs as advertised.
