Cost of a Tank Water Heater Installation in San Marcos, TX
The following factors determine the cost of installing a tank water heater:
- Type and model of water heater: The most important factor when determining the price of a water heater installation is the water heater model itself. Tank water heater models vary across the board in price due to their heating efficiency, heating components (including electric, propane, and natural gas), and other factors.
- Size of water heater: Tank water heaters come in a variety of gallon sizes. Sizing a water heater is important because it ensures enough capacity during peak use times (when the whole family is getting ready for the day, for example). Larger gallon sizes have higher costs associated with them.
- Modifications to plumbing & permits: Sometimes when we're replacing a water heater, we come across other challenges that need to be resolved first. For example, we may modify an exhaust pipe, replace a valve, or install a new water collection pan or water alarm. Regardless of what you need, we can help you get it done.

Geoff came to fix our toilet that's been acting up for a couple of weeks now. He did a great job and was very professional. He was very kind and helpful. Thanks again for the great service!
