Boiler replacement

  • All central heating boilers replaced from small domestic combination boilers to larger commercial units.
  • Conversions from old cast iron boilers to the latest in high efficiency boilers
  • Full certification and registration with Building Control is included with all replacements

Installation of all condensing boilers

  • Current energy efficiency regulations state that it is now standard practice to install condensing boilers.
  • Condensing boilers allow a far greater range of fluing options thus allowing the safe installation of a unit in more unusual places.

Power flushing

  • When upgrading a traditional floor standing boiler to a new high efficiency unit it is imperative that a full power flush be carried out on the central heating system. ‘Power flushing’ is carried out by attaching a specially designed pumping system to the boiler and radiator pipe work and forcing cleansing chemicals around the radiators, pipe work and boiler.
  • This practice can be done as part of an upgrade or can be carried out as a separate job on a existing system to improve the overall efficiency of an older system.

Condensing boilers

All experts agree that condensing boilers are beneficial from an energy saving point of view.

Finding a location and installing a condensing boiler is no different to a conventional boiler, the only difference in installation is the requirement for a condensate drain, and consideration of pluming.

They are available as regular or combination boilers and are as easy to install as non- condensing boilers. No changes to the system design are necessary, they can be installed in fully pumped heating systems without the need for any special designs.

The system does not need to be designed to condense to achieve the improved efficiency, typically a condensing boiler would have a seasonal efficiency of between 83% and 92% compared with a new non-condensing boiler at 75% and an older boiler type at 55-60.

It is not necessary to install oversized radiators, to give a worthwhile efficiency gain. No change should be made to the installation of Condensing boilers when installed as a replacement to an existing system that has larger radiators installed.
