Is a combination boiler always the best option?

Sometimes yes, sometimes no. I can help you to reach a decision by considering your heating requirements and building layout / costs.

Installation - range of systems considered:

New or replacement combination boiler including upgrading heating controls.

-redesign of existing pipe work to suit a sealed heating system.

-complete new heating system (radiators, boiler, pipe work, controls)

Stored hot water with regular heat only boiler

-upgrade existing components e.g. new boiler, cylinder, 2 or 3-port valves, pump, controls, radiators.

Unvented hot water storage - regular or system boiler

Maintain existing open vented heating circuit

- Installation of unvented hot water providing stored hot water at mains pressure.

Using a system boiler and unvented cylinder / zoned controls.

-Redesign distribution pipe work to achieve a good volume of stored hot water at outlets.

The primary heating system becomes a sealed circuit.
