Central Heating Installation

Central heating installation

Based in Cowbridge, Vale of Glamorgan, South Wales

As one of the largest heating and plumbing companies , covering South Wales and the South West, C S Boxall supplies, installs, maintains and services both condensing conventional gas boilers and condensing combination boilers. We offer a wide range of gas central heating systems to suit all homes and budgets, and are Worcester Bosch accredited installers, which enables us to provide a 5-year warranty on all Worcester Bosch installations.

Condensing conventional gas boilers

By storing hot water in a cylinder, condensing conventional gas boilers offer an instant and fast flow of hot water and are effective even when multiple taps are in operation. Condensing gas boilers are also compatible with solar and backed up with an immersion for electric hot water heating. However, condensing conventional gas boilers require more space (to store the cylinder), time to heat up the water and offer a limited amount of hot water.

Condensing combination gas boilers

Condensing combination gas boilers are ideal space savers. With no need for a cylinder, these boilers do not need a lot of space and heat up water as much water as you want, as and when you need it. However, condensing combination boilers have slower flow rates and are dependent on mains pressure. They are also only suitable for one tap operation.

C S Boxall also supplies, installs, maintains and services all types of LPG boilers for homes which are not connected to the mains gas supply.
