Tankless Water Heater Services
The days of rushing through a shower before the hot water runs out are over. Tankless water heaters have revolutionized home comfort by providing an endless supply of hot water. Instead of storing 50 gallons of water and keeping it hot 24/7, a tankless unit uses powerful gas burners or electric elements to instantly heat water as it flows through the heat exchanger. This on-demand approach dramatically reduces standby energy loss, lowering your monthly utility bills.
Beyond efficiency and endless capacity, tankless units offer a significant space-saving advantage. These compact units mount neatly on a wall, freeing up valuable floor space in your garage, basement, or utility closet. With a lifespan of 15 to 20 years—nearly double that of traditional tanks—upgrading to a tankless system is a smart, long-term investment in your home. We provide comprehensive installation, descaling, and repair services for all major tankless brands.
Signs You Need Tankless Water Heater
- Your large family frequently runs out of hot water during back-to-back showers.
- You are looking to reduce your home's energy consumption and lower gas bills.
- You want to reclaim floor space currently taken up by a bulky tank heater.
- Your current tankless unit is flashing an error code or failing to ignite.
- The hot water temperature from your tankless unit is fluctuating (cold water sandwiches).
Our Process
Flow Rate Assessment
We calculate your home's peak GPM (gallons per minute) demand to size the tankless unit correctly.
Gas and Venting Upgrades
If retrofitting from a tank, the gas line is usually upsized and special PVC or stainless steel venting is installed.
Mounting and Connection
The unit is mounted securely to the wall, and water, gas, and electrical connections are finalized.
Programming
The internal computer is programmed for your specific altitude, vent length, and desired output temperature.
What Affects the Cost
- The flow rate (GPM) capacity required for your home.
- The complexity of the retrofit (upgrading the gas line from 1/2" to 3/4" is often required for gas units).
- The routing of new intake and exhaust venting to the exterior of the house.
- Whether a recirculation pump is added for instant hot water at distant fixtures.
✓ Safe to DIY
- Checking the digital display for error codes and looking them up in the manual before calling for service.
- Cleaning the small, easily accessible inlet water filter screen.
✕ Stop & Call Us
- Attempting to descale the unit using unauthorized chemicals, which can destroy the copper heat exchanger.
- Modifying the concentric venting system; improper venting can melt the pipes or cause carbon monoxide buildup.
Frequently Asked Questions
Will a tankless water heater provide instant hot water?
Tankless means "endless" hot water, not "instant." The water still takes time to travel from the unit to your faucet. However, adding a recirculation pump can provide instant hot water at the tap.
Do tankless water heaters require maintenance?
Yes, they require annual descaling to flush mineral buildup out of the tight heat exchanger pathways. Without this, the unit will lose efficiency and eventually fail prematurely.
Can an electric tankless unit heat a whole house?
While electric tankless units exist, they require a massive amount of electrical power (often needing 3 or 4 dedicated high-amp breakers). For whole-house applications, gas-powered tankless units are heavily preferred.
