When replacing your boiler, there is a number of different options available to you. Where possible you should consider installing the highest efficiency boiler possible. This will reduce your fuel costs in the long run and may qualify you to avail of government grants.
Combi Boilers Combi boilers are common in Ireland and are what many homeowners will already have. Combi boilers are one step up from the conventional Irish arrangement of having separate units for heating the radiators and the hot water. Combi boilers heat both in one unit and ensure that an unlimited amount of hot water is readily available whenever it is needed.
Condensing Boilers Where possible, you should consider replacing your gas boiler with a condensing boiler. They use less fuel and are cheaper to run than combi boilers. Condensing boilers work by condensing the water vapour produced in the heating process, harnessing the extra heat within that would have ordinarily been lost.
