Your guide to installing your product

All our self-install products come with a manual and diagram. Some of our larger products come with a kit which includes a step-by-step guide.

Should I use vented or unvented

Both of them has its own advantages; unvented offers more pressure yet vented can continue to work even when the mains water has been turned off.

Choosing a cylinder size that is fit for purpose

Your choice depends on a number of factors. These include the size of the space available to you, the strength of the mains pressure and details of your existing heating system. We would recommend you measure your space and speak to one of our friendly operatives on 01473 276686.
