Who are we?

Newark Copper Cylinder Co. Ltd. are a manufacturer of high-quality bespoke hot water cylinders; We are a family business spanning three generations and have provided the nation with hot water storage solutions since 1977.

We pride ourselves in having the ability to work for our customers in designing and manufacturing a unit which meets their exact requirements and being able to quickly turn around products for our customer's convenience.
We are able to produce a wide range of products and specifications from small cylinders for use in a marine environment to domestic units and large industrial calorifiers.

We make a conscious effort to develop our products to suit an evolving demand and to sustain our natural environment; our cylinders can be designed to to work in conjunction with solar panels, wood burners, pellet boilers, ground source heat pumps and to work on either mains pressure or vented systems.
We manufacture all of our units in-house with a combination of high precision machinery and the flexibility of hands on craftsmanship.

Our Vision

We have always embraced the idea of making all of our products by hand; not only does this allow us to constantly ensure our units are of the highest quality and free from defects but also allows us to tailor our units to the customers exact requirements.

We also pride ourselves with our attitude towards customer service; we do not outsource or hire a dedicated customer service department, instead all our office staff are knowledgeable through industry experience and can give much more personalised customer service; the flat nature of our company's hierarchy also means when you call you can even be put straight in touch with a managing director.
