Tankless Water Heaters

1. What is a tankless water heater?

A tankless water heater, also known as an on-demand water heater, is a system that heats water directly without the use of a storage tank. When you turn on a hot water tap, cold water travels through a pipe into the unit, where a gas burner or an electric element heats the water instantly.

2. How does a tankless water heater differ from a traditional water heater?

Unlike traditional water heaters, which store and continuously heat water in a tank, tankless water heaters heat water on demand. This means they only operate when hot water is needed, eliminating standby energy losses associated with traditional water heaters.

3. What are the advantages of using a tankless water heater?

• Energy Efficiency: Tankless units only heat water when needed, reducing energy consumption.
• Space Saving: Compact, wall-mounted units free up valuable floor space.
• Endless Hot Water: Heated on demand, so you won't run out during showers or baths.
• Longer Lifespan: Tankless units can last up to 20 years with proper maintenance.

4. Are tankless water heaters suitable for all homes?

Tankless water heaters are suitable for most homes, but it's essential to consider household size, hot water usage patterns, and climate. Larger households may require multiple tankless units or a larger-capacity unit to meet hot water demand simultaneously — we can help you size the right system.

5. What maintenance is required for a tankless water heater?

Regular maintenance helps ensure optimal performance and longevity. Tasks may include flushing the unit to remove mineral deposits, checking for leaks or corrosion, and inspecting venting systems. We follow manufacturer guidelines for each brand we service.

6. Can I install a tankless water heater myself?

While some homeowners with plumbing and electrical experience may choose to install a tankless water heater themselves, we recommend hiring a licensed professional. Professional installation ensures proper sizing, safe operation, and compliance with local building codes and regulations.

7. Are tankless water heaters more expensive to purchase and install?

Tankless water heaters typically have a higher upfront cost than traditional tank heaters. Over time, energy savings and a longer lifespan can offset that initial investment. Installation cost varies depending on existing infrastructure, unit size, and complexity. Electric tankless installs often require a certified electrician to run new wiring or add breakers, since electric tankless units need higher voltage than a standard tank-style electric water heater.

8. Do tankless water heaters work well in cold climates?

Yes, but it's essential to select a unit with adequate heating capacity to meet the increased demand for hot water during colder months. Some models include features like freeze protection to prevent damage in freezing temperatures — important here in Wisconsin winters.

9. Are tankless water heaters environmentally friendly?

Tankless water heaters are considered more environmentally friendly than traditional tank heaters due to their energy efficiency. By heating water only when needed, they help conserve energy and reduce the greenhouse gas emissions associated with water heating.

10. Can a tankless water heater be used with hard water?

Yes, but mineral buildup from hard water can affect performance and efficiency over time. Regular maintenance, such as flushing the unit to remove mineral deposits, helps mitigate issues associated with hard water. A whole-home water softener can also extend the life of your unit.
