Boilers
Boilers operate by heating water to provide central heating and hot water in homes. From consistent heat for your home to controlled humidity and consistent hot water, Crystal Waters can help you find a boiler heating system that works for your home.
How Boilers Work
The process begins when the boiler ignites fuel—natural gas, oil, or electricity—to heat the water. The heated water or steam is then circulated through pipes and radiators or underfloor heating systems, effectively distributing warmth throughout the home. This method ensures that every room receives consistent and reliable heat.
The central component of a boiler system is the heat exchanger, which transfers the heat from the fuel to the water. In a typical setup, the heat exchanger is heated by the combustion process, and the resulting hot water is pushed through a network of pipes. This hot water then flows into radiators or underfloor systems, radiating heat into the living spaces.
Modern boilers are designed to be highly efficient and can be controlled using advanced thermostats and zoning systems. This allows homeowners to customize their heating needs, ensuring comfort and reducing energy consumption. Regular maintenance and timely repairs are crucial to keeping a boiler running efficiently and extending its lifespan.
Types of Boilers
- Combi Boilers
Combi boilers, or combination boilers, are a popular choice due to their compact size and efficiency. They provide both central heating and hot water in a single unit, eliminating the need for separate water tanks or cylinders. This makes them ideal for smaller homes or properties with limited space. Combi boilers heat water on demand, which can be more energy-efficient and convenient compared to traditional systems. - Heat Only Boilers
Heat only boilers, also known as regular or conventional boilers, are commonly used in larger homes with high hot water demands. They work in conjunction with a hot water cylinder and a cold water tank, providing a steady supply of hot water and central heating. These boilers are known for their reliability and are well-suited for homes with multiple bathrooms or extensive heating needs. - System Boilers
System boilers are similar to heat-only boilers but include additional built-in components, such as an expansion vessel and a pump. This design simplifies installation and maintenance. System boilers are often chosen for their efficiency and ability to handle high hot water demands. They are also compatible with solar thermal systems, offering an eco-friendly heating solution for those concerned with environmental impact. - Condensing Boilers
Condensing boilers are an advanced type of boiler designed to maximize energy efficiency by recovering heat from flue gasses that would otherwise be wasted. This process allows condensing boilers to operate at a higher efficiency than non-condensing models, potentially lowering energy bills. They are available in various configurations, including combi and system models, making them a versatile choice for modern heating needs.

After conducting a detailed inspection of your plumbing or HVAC system, your tech will diagnose and document any issues, reporting to you exactly what is happening.

After our comprehensive assessment, which may be digital or in person depending on the situation, we provide a clear and transparent proposal outlining the necessary repairs, maintenance, or enhancements you requested. The scope of the work, materials required, and the cost involved will be clearly shared with transparency so you can make an informed decision. Crystal Waters will always provide multiple options for your consideration whenever possible.
