If you’re the proud owner of a gas tankless water heater unit, you know it can significantly reduce your energy bills and provide an endless hot water supply. 

However, did you also know that regular maintenance is crucial for optimal performance? 

Unfortunately, many homeowners skip this step or delay it until there’s a problem. 

So today, we’ll explain why neglecting your gas tankless water heater unit’s maintenance could lead to costly repairs and jeopardize your safety. 

Why is regular maintenance important for a gas tankless water heater?

First, it helps prevent the build-up of sediment and scale in the unit, which leads to decreased efficiency and performance over time. 

Additionally, regular maintenance can help extend your unit’s lifespan by keeping it in good working condition. 

Finally, by performing regular maintenance on your gas unit, you can ensure it operates safely.

What is regular maintenance of gas units?

To ensure your gas unit is operating properly and efficiently, it is important to maintain it regularly. 

During your monthly inspection, you should check all connections for leaks. For gas connections, the best way to do this is to use a soapy water solution; if bubbles are present, there is a leak. Be sure to tighten or replace any faulty connections. 

You should also inspect the venting system to ensure it is not blocked or obstructed. 

If you live in an area with hard water, flush your gas unit about once every quarter.

Yes, it’s important to note that tankless units produce exhaust gases, which can be dangerous if not properly vented. 

Ensure you have your unit installed by a qualified technician and that it is properly ventilated to prevent any hazardous build-up of exhaust gases. 

Additionally, always follow the manufacturer’s instructions when performing any maintenance on your unit.
