Efficient and Reliable Heating with Boilers and Combi Boilers

Explore one of the most efficient ways to heat your home with Reliance®.

Heating and combi boilers are among the most economical and energy-efficient solutions for keeping your home warm and comfortable. These systems work by circulating hot water through radiators, baseboards, or in-floor heating, then recycling the water back to the boiler for reheating. Reliance installs high-efficiency hot water boilers, helping you save on heating bills while reducing your environmental impact.

Boilers and combi boilers provide consistent and energy-efficient heat that can power multiple systems in your home. Benefits include:

  • Radiant-style heating: Even, comfortable heat throughout your home.
  • In-floor heating: Warmth where you need it most—right under your feet.

The Benefits of Choosing a Boiler for Home Heating

Boilers are not only energy-efficient but also versatile, making them an excellent choice for home heating. They deliver hot water to heat your home in various ways, including radiators, radiant baseboards, and even clean hot water for daily tasks like showers or laundry.

Why Choose a Boiler?

  • Energy-Efficient Heating: Radiant heating systems effectively transfer heat directly to people and surfaces, allowing you to maintain a lower thermostat setting while staying comfortably warm. This can potentially reduce your heating bills and lower your carbon footprint.
  • Reliable, Consistent Warmth: Modern boilers feature fully modulating pumps and gas valves, which adjust energy usage precisely to meet your home’s needs. This ensures steady, even heating and possible greater energy savings over time.
  • Compact and Space-Saving Designs: Wall-mounted combi boilers combine heating and hot water functions into one compact unit. These systems are ideal for retrofitting in existing homes or installing in new builds where space is limited.

A boiler isn’t just a heating system—it’s an investment in efficient, reliable, and eco-friendly comfort for your home.
