Technical advice

How do I connect a boiler and solar or a heat pump to one cylinder?

Combining a boiler with solar thermal or a heat pump in one cylinder.

SuperFlow Twin Coil cylinders provide several key benefits for modern heating systems:

  • Dual Heat Source Utilisation: Efficiently harness energy from two independent heat sources. For instance, a lower coil can be dedicated to a renewable source like solar thermal, providing primary heating, while an upper coil connects to a boiler for backup or boost heating.
  • Maximised Renewable Energy Contribution: Prioritises the use of free or lower-cost renewable energy, reducing reliance on fossil fuels and lowering energy bills.
  • Consistent Hot Water Supply: Ensures reliable hot water availability, even when the primary renewable source is insufficient, thanks to the secondary coil.
  • Space Saving: Integrates two heat inputs into a single cylinder, often saving plant room space compared to separate buffer and DHW cylinders.
  • High Flow Rates: As unvented cylinders, they deliver mains pressure hot water to multiple outlets.
  • Durability & Guarantee: Constructed from high-grade stainless steel and backed by our 25 year guarantee on stainless steel unvented cylinders up to 300 litres.
  • Stainless steel cylinders over 300 litres: 12 months on the vessel, against a material defect or manufacturing fault.
  • Quality Manufacturing: Built to ISO 9001 standards in our UK facility.
