A tankless water heater is an ideal, energy-efficient upgrade for your home. Unlike traditional units, they heat water on demand, eliminating the need for a storage tank, and provide a continuous supply of hot water while taking up significantly less space.
That said, installing this type of heating system can be challenging, and any mistake can lead to inefficiency, costly repairs, and even safety hazards. To help you achieve a successful tankless water heater installation, here are some common mistakes to avoid:
Choosing the Wrong-Sized Unit
One of the most frequent mistakes homeowners make is selecting a tankless water heater that is not the right size for their needs. An undersized unit may result in an inadequate water supply during periods of high demand, while an oversized one can waste energy, leading to higher bills. To choose the best tankless heater, it’s best to calculate your household’s hot water needs and match it to a model that meets that demand.
Improper Ventilation
Proper ventilation is a must for tankless water heaters to operate safely and efficiently. Electric and gas models have different venting requirements, and failing to follow these closely can lead to ineffective operation or even hazardous situations, including the risk of carbon monoxide poisoning. When installing your chosen water heater, follow the ventilation instructions carefully or hire a professional to ensure a safe and correct procedure.
Overlooking Electrical or Gas Requirements
Another critical mistake is overlooking the specific electrical or gas requirements of tankless water heaters. Depending on the model, electric units may require a dedicated circuit or power supply, while gas ones may need an appropriate gas line. Failing to accommodate these needs can lead to performance issues, tripped breakers, and other costly damages.
Poor Placement Choices
Choosing the installation location of your tankless water heater is essential, as it can significantly impact its overall performance and longevity. For instance, placing the unit too far from outlets can result in longer wait times for hot water, counteracting the benefits of a tankless system. Ideally, the water heater should be installed close to high-demand fixtures, while avoiding spaces with poor ventilation, such as unconditioned attics or basements.
Neglecting Routine Maintenance Access
Tankless water heaters need regular upkeep to ensure they operate efficiently. However, many homeowners make the mistake of installing the unit in a location that makes it difficult to access for routine maintenance and servicing, leading to problems down the line.
During installation, ensure clear pathways that allow you or professionals ease of access when inspecting for issues, flushing the tank, and performing repairs. This upfront consideration can save you headaches and expenses in the long run.
Ignoring Water Quality
Water quality is often overlooked during the selection and installation of tankless water heaters. Hard water may cause scale buildup in the unit over time due to its high mineral content, affecting its efficiency and potentially causing premature failure. To prevent this, consider investing in a water softening system when installing your new heater.
Failing to Check Local Codes and Regulations
Each locality has specific codes and regulations governing water heater installation, including venting, clearance, and positioning requirements. Failing to comply with these can lead to fines or even result in re-installation, which can be costly and troublesome.
Consulting your local building department to determine the specific requirements for tankless water heaters before beginning installation can save you from potential legal issues. You can also hire a plumber to do the job for you, as they are familiar with local building codes and can make the process faster and easier.
Skipping Professional Installation
While some may be tempted to cut costs by performing a DIY installation, this often leads to future problems. Professional installers have the expertise required to navigate the intricacies involved in tankless water heater installation. With their help, you can be at ease knowing that your unit will be installed safely, correctly, and in compliance with local codes.
