Tankless Water Heaters
What Is a Tankless Water Heater?
Unlike traditional models that store and heat water in a tank, tankless water heaters heat water on demand. When you turn on a hot water tap, cold water flows through the unit’s heating elements or gas burners, instantly delivering hot water.
Because there’s no tank to store water, you get endless hot water, reduced standby energy losses, and a much smaller unit that takes up less space.
Tankless water heaters are ideal for:
- Homes with multiple family members or high hot water demand
- Energy-conscious homeowners
- Small spaces where tank models aren’t practical
- Long-term savings on utility bills

Frequently Asked Questions
Are tankless water heaters more expensive to install?
Yes, tankless systems usually have a higher upfront cost due to additional venting or electrical upgrades. However, they provide long-term savings and a longer lifespan.
Can I install a tankless unit in place of my current tank model?
Absolutely. We often convert homes from traditional to tankless systems. We’ll assess what adjustments are needed and explain the process clearly.
Do tankless water heaters provide instant hot water?
They heat water instantly, but depending on your plumbing layout, it may take a few seconds to reach your tap. Recirculation systems can provide near-instant delivery.
How often should I flush or descale my tankless heater?
At least once a year—or more often if you have hard water. Regular descaling prevents damage and maintains peak efficiency.
