Why Upgrade Your Home's Water Heater?

A dependable water heater isn’t just about comfort — it’s about efficiency, savings, and peace of mind.

Modern water heaters, especially tankless systems, offer advantages like:

• Endless hot water on demand
• Improved energy efficiency
• Lower utility bills
• Compact design for space savings
• Longer lifespan compared to traditional tanks

In South Carolina’s changing seasons, having a system you can trust is essential. Whether you're considering a tankless upgrade or simply replacing an old traditional tank, On Call makes the process smooth and stress-free.

The Benefits of Installing a New Water Heater

Energy Efficiency and Savings

New water heaters — especially ENERGY STAR® certified models — use less energy while delivering better performance. Whether you choose a tankless or traditional system, modern units help lower your energy bills and reduce your environmental footprint.

Pro Tip: Keep your water heater running efficiently for years with routine maintenance from our service team.

Endless Hot Water (Tankless Options)

With a Rinnai® or A. O. Smith® tankless water heater, you’ll enjoy continuous hot water for all your showers, laundry, and dishwashing needs — without running out or waiting for a tank to refill.

Compact Design for More Space

Tankless water heaters are wall-mounted and take up much less space than traditional tanks. Even high-efficiency traditional tanks today are smaller and better insulated, freeing up room in your utility area.

Professional Installation Done Right

Our expert technicians ensure your new water heater is installed safely and efficiently:

• Correct sizing for your household needs
• Clean, code-compliant installation
• Smart thermostats or Wi-Fi connectivity (optional)
• Disposal of old unit (if applicable)

Improved Home Value

An upgraded, energy-efficient water heater is a smart investment and a strong selling point when it's time to move.
