Understanding the Average Cost of Tankless Water Heater Installation

Best-In-Class Water Heater Services for Commercial and Residential Customers In Los Angeles

Installing a tankless water heater involves more than just the cost of the unit itself. To accurately estimate the expenses, it’s essential to consider several factors that contribute to the overall cost. Let’s take a closer look at each aspect:

  1. Unit Cost: The price of a tankless water heater can vary depending on the brand, size, and features. On average, the cost of a tankless unit ranges from $1,000 to $4,000. Higher-end models with advanced features and larger capacities tend to be on the higher end of the price spectrum. We here at ZHH Plumbing and Water Heaters provide the best recommendations to suite your needs and the best quotes in Los Angeles coupled with our rebate up to $1,000.

  2. Professional Installation: Unlike traditional water heaters, tankless models often require professional installation due to their complexity and specialized requirements. Hiring a licensed plumber or a qualified technician, such as ZHH Plumbing and Water Heaters, is crucial to ensure proper installation and optimal performance. The installation cost can vary based on factors such as labor rates, location, and any additional work required, such as retrofitting the existing plumbing system.

  3. Retrofitting and Upgrades: When transitioning from a traditional water heater to a tankless system, there may be additional costs associated with retrofitting the plumbing system. Tankless water heaters require specific venting and gas supply considerations, which might involve modifications to accommodate the new unit. ZHH Plumbing and Water Heaters provides honest estimates for the highest quality of work.

  4. Maintenance and Warranty: While not directly related to installation costs, it’s important to consider long-term expenses such as maintenance and warranty coverage. Tankless water heaters generally require periodic maintenance to ensure optimal performance and longevity. Additionally, warranty coverage may vary depending on the manufacturer and model. Research the maintenance requirements and warranty terms of different tankless water heaters to estimate the associated costs.
