How to choose the right 36 kW unit
-
Check physical dimensions
Measure your installation space carefully before buying. The Tempra 36 Trend is only 4.63 inches deep, making it the most compact option. It also measures 16.6 inches wide and 14.5 inches tall. The Tempra 36 Plus is wider at 19.5 inches and longer at 21.5 inches. Its height is just 9.5 inches, which suits low-profile mounts. Compare these exact numbers to your available wall area. Ensure you have enough clearance for maintenance access. The weight for both models is 19 pounds, so standard wall anchors will suffice for support.
-
Verify electrical compatibility
All listed models require a 240V power supply. They are designed for homes with a 300 A electrical service. This high capacity ensures the heater can draw enough power for instant hot water. You must confirm your home’s electrical panel can handle this load. If your service is lower, these units may trip breakers or fail to operate correctly. This requirement applies to every model in this guide. Do not assume standard residential circuits are sufficient. Consult an electrician to verify your panel’s total amperage before installation.
-
Select your preferred color
The available finish options are limited but distinct. The Tempra 36 Trend models come in a clean white finish. This color blends well with standard utility rooms or white cabinetry. The Tempra 36 Plus offers a gray finish. Choose the gray option if you prefer a more industrial look or if your wall color is darker. The color does not affect performance or efficiency. It is purely an aesthetic choice based on your interior design. Match the unit’s color to your existing appliances or wall paint for a cohesive appearance.
-
Consider model availability
Model names may vary slightly between listings. The Tempra 36 Trend is the current standard offering. The Tempra 36 Plus is an older model that may be harder to find. Check the specific model number on the product page. The Plus version features a digital control interface, which some users prefer. The Trend version focuses on simplicity and energy efficiency. Availability can impact your decision if you need a specific feature set. Verify the exact model name to ensure you get the hardware you expect upon delivery.
-
Assess power output needs
Each unit delivers 36 kW of heating power. This wattage is suitable for high-demand households. It supports multiple simultaneous uses, such as showers and laundry. The electric fuel type means no gas lines are needed. This simplifies installation in homes without natural gas. The 36 kW rating ensures consistent water temperature even during peak usage. However, it requires significant electrical infrastructure. Ensure your home can support this continuous power draw. This capacity is ideal for larger homes with robust electrical systems.
