System Boilers

System boilers represent a perfect balance between traditional heating systems and modern efficiency. Unlike combi boilers, system boilers work with a hot water cylinder to store heated water, making them ideal for homes with higher hot water demands.

Key benefits of system boilers include:

  • Ability to supply hot water to multiple taps simultaneously
  • Compatibility with solar thermal systems
  • Excellent water pressure even in larger properties
  • Energy-efficient operation
  • Space-saving compared to conventional boilers

For UK households with multiple bathrooms or high hot water usage, system boilers offer a reliable and efficient heating solution.

Hot Water Cylinder System Explained

The heart of a system boiler setup is its hot water cylinder. Understanding how this system works is key to appreciating its benefits:

  1. The system boiler heats water directly from the mains.
  2. Heated water is stored in an insulated hot water cylinder.
  3. When a hot tap is turned on, water is drawn from the cylinder.
  4. The boiler replenishes the cylinder with hot water as needed.

Advantages of stored hot water:

  • Consistent supply for multiple outlets
  • Better suited for properties with low mains pressure
  • Potential for faster bath filling
  • Can be heated by alternative sources (e.g., solar panels)

This setup ensures a steady supply of hot water, even during peak usage times, making it ideal for busy households.

Meeting High Hot Water Demand

One of the primary advantages of system boilers is their ability to meet high hot water demands efficiently. This makes them particularly suitable for larger households or properties with multiple bathrooms.

Key features for high demand:

  • Stored hot water ready for immediate use
  • Ability to supply multiple outlets simultaneously
  • Quick recovery times for reheating the cylinder

Customizing cylinder size for household needs:

  • Small (90-120 litres): Suitable for 1-2 bedroom properties
  • Medium (150-180 litres): Ideal for 3-4 bedroom homes
  • Large (180-300 litres): Best for large families or luxury properties

At Axiom Heat, we’ll assess your household’s specific needs to recommend the perfect system boiler and cylinder combination.

Solar Thermal Compatibility

System boilers excel in their ability to integrate with solar thermal systems, offering an eco-friendly and cost-effective heating solution.

How solar thermal integration works:

  1. Solar panels on your roof collect heat from the sun.
  2. This heat is transferred to a fluid in the solar thermal system.
  3. The heated fluid circulates through a coil in your hot water cylinder.
  4. The cylinder water is heated by the coil, reducing the work required from your boiler.

Potential energy savings and environmental benefits:

  • Up to 60% reduction in water heating costs
  • Lower carbon footprint
  • Renewable Energy Incentive eligibility
  • Increased property value

By combining a system boiler with solar thermal technology, you can significantly reduce your energy bills and environmental impact.

Scalability for Growing Families

One of the key advantages of system boilers is their adaptability to changing household needs. As your family grows or your hot water requirements increase, a system boiler setup can be easily modified to meet new demands.

Adapting the system as household needs change:

  • Upgrading to a larger hot water cylinder
  • Adding smart controls for more efficient operation
  • Integrating with renewable technologies like solar thermal

Options for upgrading capacity:

  • Installing a more powerful boiler
  • Adding a second hot water cylinder for very high demands
  • Implementing zone control for more targeted heating

With a system boiler, you have the flexibility to adapt your heating system as your needs evolve, without the need for a complete system overhaul.

Pressure System Benefits

System boilers operate as a sealed system, offering significant advantages in terms of water pressure and efficiency.

Advantages of a pressurized system:

  • Consistent, high-pressure hot water to all outlets
  • Faster filling of baths and powerful showers
  • No need for a feed and expansion tank in the loft
  • Reduced risk of freezing pipes in winter

Suitability for properties with poor mains pressure:

  • The stored hot water isn’t reliant on mains pressure
  • Pressure can be boosted within the system if needed
  • Ideal for multi-story homes where water needs to travel upwards

With a system boiler, you can enjoy powerful showers and fast-filling baths, even if your local mains pressure is less than ideal.
