Choosing the Right Domestic Hot Water Cylinder


Selecting the correct domestic hot water cylinder is crucial for ensuring adequate hot water supply and optimising energy usage in your home. Key factors to consider include, for example, the size of your household, typical hot water demand patterns (e.g., number of bathrooms, shower usage), the type of heating system you have (boiler, heat pump, solar thermal), and the available installation space. Our experienced team can, of course, provide guidance to help you choose the most suitable model.

Our domestic cylinders are, furthermore, built with durability and efficiency in mind. Indeed, many of our products feature advanced insulation techniques to minimise heat loss and subsequently reduce energy bills. We also offer bespoke options if you have specific requirements for your domestic hot water system.



Types of Domestic Hot Water Cylinders We Manufacture


Our extensive range caters to various domestic requirements:

  • Unvented Domestic Hot Water Cylinders: These provide high-pressure hot water directly from the mains, ideal for powerful showers and fast-filling baths. Consequently, they are a popular choice for modern homes.
  • Thermal Stores for Domestic Hot Water: Offering excellent flexibility, our domestic thermal stores can integrate multiple heat sources, such as a boiler alongside solar thermal panels or a solid fuel stove. They provide mains pressure hot water via an efficient internal heat exchanger.
  • Buffer Vessels (Domestic Applications): Increasingly important for domestic heat pump installations, these smaller buffer vessels add vital system volume, preventing short-cycling and improving heat pump efficiency.
  • Special & Bespoke Domestic Cylinders: For non-standard requirements, we can often design and manufacture a custom domestic hot water cylinder to your exact specifications.
