Tankless Water Heating Solutions
Serving Allen and Surrounding Areas
Unlock Consistent Comfort
Beyond Traditional Hot Water Systems
Experience the modern convenience and efficiency of tankless water heaters. Unlike conventional tank units that heat a large volume of water and store it, tankless systems heat water on demand, only when you need it. This means no more waiting for a tank to refill or worrying about running out of hot water during peak usage times. Enjoy a continuous flow for multiple showers, appliances, and faucets simultaneously.
These innovative systems offer significant advantages in terms of performance and lifestyle. The immediate access to hot water streamlines daily routines, from washing dishes to laundry. Additionally, they often have a longer lifespan than traditional tank models, providing reliable hot water for years to come with proper maintenance. Make the switch to a tankless system and enjoy unparalleled comfort and convenience in your home.
How On-Demand Water Heating Works
Tankless water heaters, sometimes called demand-type or instantaneous water heaters, work by heating water directly as it flows through the unit. When a hot water tap is turned on, cold water travels through a pipe into the unit. Inside, either a gas burner or an electric element heats the water rapidly. This process continues for as long as the hot water tap is open, providing an endless supply.
The size and capacity of a tankless unit depend on your household’s peak hot water demand – how many devices might use hot water at the same time. Proper sizing is crucial to ensure the unit can deliver sufficient hot water flow rate (measured in gallons per minute or GPM) and temperature rise for your needs. Getting the right unit installed ensures optimal performance and efficiency.
Expert Installation and Upgrades
Choosing to install a new tankless water heater or replace an old tank unit is a significant home improvement that requires professional expertise. Our team specializes in the precise installation needed for these advanced systems, ensuring proper gas line sizing (for gas units), venting, electrical connections, and water line modifications. We handle the entire process, from selecting the right unit for your home’s size and hot water needs to the final hookup and testing.
Upgrading from a traditional tank to a tankless system can be complex, often requiring changes to plumbing, gas, or electrical lines. We assess your current setup and provide a clear plan for a smooth transition. Our goal is to minimize disruption while ensuring your new tankless system operates safely, efficiently, and reliably from day one, providing you with continuous hot water and freeing up valuable space.

I had a great experience with Layman Plumbing when they came to resolve my kitchen plumbing. They identified the issue with my sink pretty quickly and helped me understand the problem. I was given an honest estimate before proceeding with the repair and even told me how I can prevent further issues overtime. The work was done quickly, and they even cleaned up the area afterward, which I really appreciated. My sink is now working perfectly! Highly recommend!

We called Mr. Layman and he provided very professional and timely services for us. During the first trip, he helped us make sure that we could still have hot water from the remaining water heater during the upcoming snow days. He even called the manufacturer on our behalf so our water heater would be covered by the warranty. During the second trip, Mr. Layman and his assistant were very thorough and responsible to make sure the old water heater was taken off safely and the new water heater was installed perfectly with proper functions and no potential leaks. We really appreciate his high professionalism. Thanks so much, JohnGoogle rating score: 5.0 of 5, based on 11 reviews
