Standard Vented Direct

Our copper open vented direct hot water cylinders utilise an electric immersion as the primary heat source to heat the store.

Manufactured to BS1566 specification, they provide the perfect like for like replacement solution for existing vented cylinders, saving on installation time.

Utilising electric immersion as the primary heat source, the unit maximises the benefits of off-peak electricity supplies. The water is heated by the immersion heater which sits inside the 2″ 1/4 boss within the cylinder.

If our online range does not suit your application, go to the Vented Cylinder product page to see options available or email with your specific requirement.
