Bennett Tankless Water Heaters: Hot Water That Keeps Up
Tankless installation, conversion and maintenance, with the unit sized to how your household actually uses hot water.
Tankless Installation Sized and Installed Properly
A tankless water heater heats water as it flows, so it does not run out and it does not spend energy keeping a full tank hot. Sized wrong, though, it struggles when two showers run at once.
We size the unit to your household's peak demand and the temperature of the incoming water. Converting from a tank usually means a larger gas line or dedicated electrical circuit and new venting, and we quote all of it up front.
Tankless units need descaling as minerals build up in the heat exchanger. We set up isolation valves at install so that service is quick for years to come.

Tankless Water Heaters FAQs
Q: Is a tankless water heater worth it?
For many households, yes — unlimited hot water, a smaller footprint, lower standby energy use and a longer lifespan than a tank. The upfront cost is higher, especially when gas or electrical upgrades are needed.
Q: Can a tankless water heater run out of hot water?
It will not run out, but an undersized unit can only heat so much water at once. Running several showers and appliances together is where correct sizing matters.
Q: Do I need a bigger gas line for tankless?
Often, yes. Gas tankless units need more gas at full fire than most tank heaters, so the line is checked and upsized if needed.
Q: How often does a tankless water heater need descaling?
Usually once a year in areas with moderate to hard water. Isolation valves installed with the unit make descaling quick.
Q: How long do tankless water heaters last?
With regular maintenance, around 20 years — roughly twice the typical life of a tank water heater.
Q: Gas or electric tankless — which is better?
Gas units handle higher demand; electric units are simpler to vent but may need a large electrical service upgrade. We compare both for your home.
