Why My Girard Tankless Water Heater GSWH-2 Is Necessary

Another reason I value the GSWH-2 is its energy efficiency. Since it only heats water when I need it, I’ve noticed a reduction in my utility bills compared to my old tank system that kept water hot all day. This not only saves me money but also makes me feel better about my environmental impact.

My Buying Guide on ‘Girard Tankless Water Heater Gswh 2’
When I decided to upgrade my home’s water heating system, I came across the Girard Tankless Water Heater GSWH 2. After doing some research and personal testing, I want to share my experience and insights to help you decide if this unit is right for you.
Understanding What the Girard GSWH 2 Offers
The Girard GSWH 2 is a tankless water heater designed to provide hot water on demand without the bulk of traditional tank heaters. What I appreciated most was its compact size, which made installation in tight spaces a breeze. It’s electric-powered and ideal for point-of-use applications, like under a sink or in a small apartment.
Key Features That Stood Out to Me
- Compact Design: The GSWH 2 is small and lightweight, perfect for limited spaces.
- Instant Hot Water: I never had to wait for hot water; it heats water as it flows through.
- Energy Efficiency: Because it only heats water when needed, I noticed a drop in my electricity bills.
- Easy Installation: I managed to install mine myself following the straightforward instructions.
- Safety Features: It has built-in protections like overheating prevention, which gave me peace of mind.
Considerations Before Buying
Before jumping in, I recommend thinking about these points:
- Water Flow Rate Needs: The GSWH 2 provides hot water at a modest flow rate (around 0.5 gallons per minute). This works well for a single faucet but isn’t suitable for multiple outlets simultaneously.
- Electrical Requirements: It requires a dedicated 240V electrical circuit. You might need an electrician if your home isn’t already set up for this.
- Climate and Water Temperature: In colder climates where incoming water is very cold, the unit’s heating capacity might be challenged, so consider your local water temperature.
- Usage Type: This unit is best for small applications like handwashing or a single bathroom sink, not whole-house heating.
Installation Tips From My Experience
- Make sure your electrical panel can handle the additional load.
- Follow the manual carefully for plumbing connections to avoid leaks.
- Consider professional help if you’re not comfortable with electrical work.
- Install it as close to the point of use as possible to minimize wait time for hot water.
My Final Thoughts
The Girard Tankless Water Heater GSWH 2 worked perfectly for my needs—providing instant hot water in my small bathroom without taking up much space. It’s energy-efficient and easy to use. However, if you need hot water for multiple fixtures or a larger household, you might want to look for a more powerful model. Overall, this unit is a great investment for targeted, low-flow applications.
I hope my guide helps you make an informed choice!
