Gas Combi Repairs and Service

From the earlier Worcester Heatslave’s and Vaillant Sine 18 models of combination boilers, of the late 1970s, the idea of one gas appliance delivering constant hot water, together with the ability to provide heating for radiators, has come a long way.

Combination boilers or Combi’s as they are commonly known, are now commonplace in domestic property’s. They provide a neat and compact solution to new build and existing property requirements alike. Modern design, high efficiency condensing boilers are sedbuk A-rated, achieving this partly by extracting the latent heat from the burnt gas’s products of combustion, with a high-efficiency heat exchanger and modulating air/gas ratio combustion process. This results in the water vapour in the products of combustion reaching “dew point”, forming condensate, which is safely drained away; hence the term condensing boiler. Checking the CO/CO2 ratio and the individual CO and CO2 content of the appliance’s flue products, together with the gas rate, is necessary. The competent use of a flue gas analyser is vital.

I attend Manufacturer’s training courses on servicing and repair of condensing combi, system and heating boilers, and so can provide a reliable servicing and repair service for you.
