All Solutions

If you want a new gas boiler, an upgrade of your heating system or an energy efficient full heating system, we can offer many solutions. This includes SEAI grant upgrades for the installation of a gas boiler together with heating controls. If your boiler is broken beyond repair, we can install a new boiler without delay.

Yes. Allgas are at least 20% cheaper than larger competitors.
You can save up to 20% on heating bills by changing from your old boiler to a High Efficiency A rated gas boiler and up to 35% if you also upgrade heating controls. If your boiler is over 8 years old it would be a Standard Efficiency boiler with an efficiency of less than 75%. New High Efficiency A rated condensing gas boilers have a rating of over 90%. This is done by recycling the flue gases of the boiler to produce more heat.
Allgas Heating, Bathrooms & Plumbing can upgrade your boiler to a high efficiency gas boiler in just one day, with no fuss or mess. We are always very conscious that we are working in your home. We will take away all rubbish including your old boiler on completion. The addition of heating control upgrade adds an extra two days to the job generally. We can upgrade your heating controls with minimum disruption and leave you with an energy efficient and comfortable home.
Grants are available from the SEAI for the installation of a High Efficiency gas boiler together with Heating Controls under the Better Energy Homes Scheme. Allgas Heating, Bathrooms & Plumbing is a registered contractor under the Better Energy Homes Scheme. For full details see Grants and Tax Back.

Grants for elderly people are also available from local councils for a full heating system where there is no heating system or for a boiler replacement where a boiler is beyond repair. For full details see Grants and Tax Back.

If the cost of the work (or this work and other work on your home) is over €5,000 including vat you can get tax credit at a rate of 13.5% of the total cost (up to a maximum of €4,050 tax back). For full details see Grants and Tax Back.
There are a number of different types of boiler ie system boilers, heat only boilers and combi boilers – all of which we can advise you on.
Allgas Heating, Bathrooms and Plumbing is certified to install, service and repair all boilers currently on the market e.g. Ideal Logic, Ideal Vogue, Worchester Bosch, Gloworm and Vaillant boilers.
Yes we install oil boilers throughout the greater Dublin area. You can get a grant under the Better Energy Homes Scheme for the installation of an oil boiler and heating system controls upgrade.
Yes. We install underfloor heating which works very well with high efficiency boilers and is very useful for heating difficult areas like conservatories.
Heating Controls Upgrades are a really good idea as you will save money on your heating bills and get a grant under the Better Energy Homes Scheme towards the cost of doing so. You can get a grant just for the controls upgrade or for a boiler and controls upgrade.

With these controls you match your heating and hot water schedules to your living patterns. Splitting your home into two independently controlled zones (space and water) allows you to heat your hot water without having your radiators heat. These controls, which are electronic, allow you to control the temperature as well as the time in each zone. Thermostatically Controlled Radiator Valves (TRVs) allow you to adjust the individual temperature in every room. Having a separate control for your hot water is particularly useful in summer months as using your gas boiler to heat your hot water is more economical than using your immersion.

As your requirements differ from day to day a 7 day programmer will optimise savings allowing you to adjust to your individual living & working pattern.

You can also save on heating bills by only having the part of the house you are using, or about to use, heated and by being able to have different temperatures in different parts of your house at different times.

We would need to install controls to provide a minimum of two zones ie heating and water. These controls consist of a 7 day programmer, room thermostat and cylinder thermostat. A minimum of half of your radiators must be fitted with thermostatic radiator valves unless you are putting in a third zone e.g. splitting upstairs and downstairs radiators into two heating circuits.
You could expect to save up to 15% annually in heating bills by upgrading heating controls and up to 35% if you also install a high efficiency boiler.
Quite simply our expertise, experience, professionalism and courtesy, the back up of almost 30 years experience and the Allgas guarantee.


Delighted with the job. From start to finish the lads could not have been more professional and efficient. They did an excellent job and left the house clean and tidy. I couldn’t recommend them enough.
John, Drumcondra, boiler and controls upgrade, January 2016
Can’t recommend Allgas enough. Had my new boiler fitted last week and from start to finish they were extremely professional. Graham and Anthony did a fantastic job and left the place spotless when finished. Delighted with the price and workmanship.
