A gas boiler service ensures that your system is running at its maximum efficiency levels and ensures that no fuel (and, therefore, money) is wasted unnecessarily when operating your gas boiler. The service will highlight any issues you many have with your boilers efficiently or output. This could help with costly gas boiler repairs.
You could also have a CO alarm fitted with your boiler service and save money. DeWAR Gas Service have an online promotional price if you book them together online.
You could also have your radiators re-balanced in your home when your gas boiler is having its annual service. Dewar Gas Service have an online promotional price if you book them together online,
Water pressure is at 1.5mbar and if not to refill same.
It is important to know under Irish Law it is a criminal offense for anyone that is not certified as a RGI (Registered Gas Installer) to work on your gas boiler boiler or gas line. All our staff at DeWAR Gas Service are directly employed and registered gas installers.
Below you will find a complete gas boiler service checklist which outlines everything that you should expect/demand from your gas contractor when they are carrying out an annual gas boiler service for your heating system.
DeWAR Gas Boiler Service Checklist:
Gas Boiler Visual Inspection:
• Make sure the gas boiler’s location is suitable. • Check that the gas boiler is properly ventilated. • Look for visible damage on the gas boiler.
Check the following:
• Check the flue’s location and condition. • Check for spillages around the flue. • Check the condensate drainage system (this only applies to high efficiency condensing boilers) • Check that the gas boiler has suitable clearance from any flammable materials. • Check the main burner and clean it where necessary. • Check the main burner operation and adjust if need be (the manufacturer’s specifications should be checked when doing this). • Check the pilot burner and its cables. They should also be cleaned if necessary. • Check the heat exchanger and clean where necessary. • Check the flue’s effectiveness while running the gas boiler. • Check to make sure that a 3-amp fuse is properly connected. • Check for electrical isolation. • Check electrical wiring for damage. • Check that electrical wiring is properly connected to the gas boiler. • Check to ensure that the gas boiler’s thermostat is functioning correctly. • Check the system’s pressure levels (the manufacturer’s specifications should be checked when doing this). • Check the expansion vessel and charge it (if necessary). • Check that the flue guard is fitted properly. • Check boiler controls (where applicable). These include zone valves, time clock, and the thermostat. Once all checks are completed, a combustion efficiency test should be carried out.
After the gas boiler service is completed a Declaration of Conformance Certificate 3 is issued by the registered gas installer.
if you would like your boiler serviced you could book it online or by calling us on 015143344 anytime. We are service all areas of Dublin 24 hours a day.
How Does a Combi Boiler Work?
Combi Boiler / Combination Boiler
A combi boiler or ( combination boiler ) is an ingenious space-saving idea and an increasingly popular choice in homes. Combi boilers now account for well over half of all the new domestic boilers installed every year.
A combi boiler is both a high-efficiency water heater and a central heating boiler, combined within one compact unit. Therefore, no separate hot water cylinder is required, offering space saving within the property.
Combination boilers are capable of providing instant hot water and heating while saving space within a home.
The conventional arrangement in Ireland is to have a normal boiler which heats the radiators via a sealed water circuit. By “sealed” it is meant that the water is contained within the system, going around in a loop between the radiators and the boiler.
To heat the “domestic hot water” (i.e. the water that comes out of the hot taps) the storage cylinder in the hot press has a coil in it through which the “radiator water” flows.
The disadvantage of this arrangement is that if the cylinder does not have hot water in it you have to wait some time for the coil to heat it up.
A ‘combi’ boiler is a boiler which combines both a conventional boiler for radiators and an independent water heater, together in the one unit. This dispenses with the hot water cylinder in the hot press. But better still, it means that hot water is always available instantly and for as long as you need it.
Control valves inside combi boilers operate in different directions, either letting the water flow through the central heating system or diverting it to a hot water tap, as required, but never both at the same time.
Important Factors Affecting Operation of a Combi Boiler
Combi boilers require sufficient mains water pressure in order to deliver a good water flow rate; low mains water pressure means hot water will merely trickle. If your mains water pressure is low or you have more than one bathroom, a conventional system boiler might be a better option for you.
It is also important to ensure that the heat output of the boiler is correct for your needs. Combi boilers have two heat outputs: one for Domestic Hot Water and the other for Central Heating. More effort and hence more heat is required to produce hot water than to heat a home through the radiators, so it is usually the hot water output that determines your choice of combi boiler.
Benefits
Provides limitless hot water on demand.
Can be an economical option, as combi boilers only heat the water you use.
A great space-saving solution with no need for a separate cold water tank or hot water cylinder.
Installation may be quicker as there are fewer parts in a combi central heating system.
It is strongly recommended that you get an annual gas boiler service carried out on your central heating system. A gas boiler service ensures that your system is running at its maximum efficiency levels and ensures that no fuel (and, therefore, money) is wasted unnecessarily when operating your gas boiler. The service also acts pre-emptively, weeding out small problems before they can take hold and cause larger problems (such as boiler breakdown) which would require costly gas boiler repair services further on down the line.
Among the main things which are inspected during an annual gas boiler service are boiler location, ventilation, and clearance. Once these are deemed to be acceptable the gas boiler can be cleaned and reassembled. Lastly, the gas boiler’s functions are tested to make sure that everything is in working order and a combustibility test is carried out to ensure that the gas boiler is working at its full capacity.
Gas boiler services can only be carried out by an RGI (registered Gas Installer) who represents the RGII (Registered Gas Installers Ireland). All DeWAR gas contractors are registered gas installers.

• Check the expansion vessel and charge it (if necessary).
• Check that the flue guard is fitted properly.
• Check boiler controls (where applicable). These include zone valves, time clock, and the thermostat.
Once all checks are completed, a combustion efficiency test should be carried out.
After the gas boiler service is completed a Declaration of Conformance Certificate (sometimes called a ‘Completion certificate) is issued by the registered gas installer.
Please note that while this is what is typically involved in a gas boiler service, no two gas boilers are exactly alike. Some units may require a slightly non-conventional approach to servicing. In all cases, it is best advised to adhere to the manufacturer’s specifications when having a gas boiler serviced.
