At Hot Water Guys, we specialize in installing units that are specifically designed to handle the flow requirements of modern Houston homes.

Modern tankless units come equipped with digital controllers that allow you to set the water temperature to the exact degree. This precision ensures safety, preventing scalding while also maximizing energy savings. Some models even feature Wi-Fi connectivity, allowing Houston homeowners to monitor their energy usage and receive maintenance alerts directly on their smartphones.

Tankless heaters include multiple safety sensors that monitor water temperature, exhaust gas, and even internal components to prevent overheating or leaks. Because there is no large tank of standing water, the risk of a catastrophic tank failurewhich can flood a garage or utility room with 50 gallons of watercompletely eliminated.

any questions?
A tankless water heater heats water on demand rather than storing it in a tank. When you turn on a hot water tap, cold water flows into the unit and is heated by a gas burner or electric element before being delivered to the faucet. This process provides a continuous supply of hot water without the need for a storage tank.
Yes, tankless water heaters are more energy-efficient than traditional tank water heaters. They only heat water when needed, reducing energy consumption and lowering utility bills. On average, they can be 24-34% more efficient for homes that use 41 gallons or less of hot water daily.
No, tankless water heaters provide an endless supply of hot water as long as the demand does not exceed the unit's capacity. However, if multiple high-demand appliances are used simultaneously, you may experience a reduction in water temperature.
The cost to install a tankless water heater can range from $3,000 to $6,500, including the unit and installation. Factors affecting the cost include the type of heater, installation complexity, and any necessary upgrades to your home’s plumbing or electrical systems.
Tankless water heaters require proper venting, a dedicated gas line or sufficient electrical capacity, and a location that prevents freezing. Professional installation is recommended to ensure safety and optimal performance.
While some basic maintenance tasks like cleaning the air filter can be done by homeowners, it’s best to have a professional perform thorough maintenance to ensure all components are properly inspected and serviced.
Regular maintenance can significantly extend the lifespan of your tankless water heater by preventing issues that could lead to costly repairs or system failure. It ensures the unit operates efficiently and reliably over its lifespan.
Signs include inconsistent water temperature, reduced water flow, strange noises, or error codes displayed on the unit. These symptoms indicate potential issues that require professional attention.
Maintenance typically includes descaling to remove mineral buildup, cleaning the air filter, checking the burner or heating element, and inspecting the venting system. Regular checks ensure that all components are functioning correctly.
