Frequently Asked Questions

What is flow rate?

Flow rate is the amount of hot water the unit can produce per minute. If it’s too low for your needs, you can run out of hot water for critical applications. To calculate the required flow rate for your facility, you need to factor in the total number of appliances and fixtures.

Are tankless systems an ideal solution for commercial enterprises?

Yes. Tankless systems offer exceptional energy efficiency and long-term savings. Their minimal installation footprint, reliability, and energy-efficient operation make them well-suited for businesses throughout Texas.

What happens if I don't schedule maintenance?

Failure to comply with manufacturer maintenance recommendations and schedules can void warranty coverage and may cause a critical system failure. Adhering strictly to all maintenance guidelines and schedules is advisable.
