Zoned Central Heating

If your home was built before 2006 you may be eligible for a grant to install zoned central heating with heating controls. Working in line with home heating controls this could save you up to 20% on your home energy bills.

What is Zoned Central Heating?

Zoned central heating means that your home heating system is split into separate independent zones. This is much more energy efficient. You can the use smart controls to send heat to each zone separately. This will ensure that you don’t use any excess energy and you can save money on your home heating bills.

A smart heating system is designed to give you full control over your energy usage. Right now when you heat your radiators you may also be heating your water tank even though you don’t need hot water. This wastage could mean you are using up to thee times as much energy as you need to heat your home. It’s bad for the environment and bad for your bank account.

A typical Home Zoning set-up might include:

  • Zone 1 – Upstairs Heating

  • Zone 2 – Downstairs Heating

  • Zone 3 – Hot Water

Why Do i Need Replacement Radiators ?

In most cases your central heating system will incorporate a number of radiators, and there are several good reasons you might need replacement radiators.

As radiators age, they become inefficient and may begin to develop leaks. This reduces the amount that they are able to heat up and increases the amount of energy needed to heat your home. In short, old inefficient radiators cost you more to run every day that passes.

If you are considering having a new gas central heating boiler installed, it may be time to also consider replacing your radiators. Even with a new and efficient boiler it will be more cost-effective to run it with replacement radiators. Upgrading your heating system piece by piece is possible, but it will cause less disruption and be much simpler if you take the plunge and tackle it all at once.

Another option for replacing your radiators in Dublin is the growing popularity of feature radiators. Standard panel radiators are available in different designs but are generally just what the name implies – flat panels.

They can be bulky and unattractive, occupying space in your room that could be better used.

Is there a grant available for a boiler upgrade?

Currently there is no grant specifically available for a boiler upgrade. However, if your home was built before 2006, SEAI are offering grants of up to €700 for upgrading your heating controls. This is something we always recommend to our customers as it can help you save a further 20%* on your energy bill. Using a method called zoned heating you can gain full control of your system and stop wasting heat that YOU own.

Combination Boiler Installation Price

A combination boiler provides both heating and hot water, Combination boilers heat the hot water instantly when their is a demand (Similar to an electric shower). With a combination boiler there is no cylinder required, combination boilers are ideal for apartments or homes with 1 bathroom.

For combination boilers we have created two estimate charts

There may be additional boiler installation costs. See below for example


The location of your existing gas boiler may impact the costings, this is particularly true if you current gas boiler is located on an internal wall of floor with no direct access to the outside for flue termination. If you current boiler is located in the attic space the flue ( boiler exhaust) may be terminating at roof level. This will increase installation costs.

Gas Pipe Size

The current gas pipe may be undersized and may need upgrading

Condesate Disposal

Heating Systems FAQ


    A central heating system that includes the boiler and about eight radiators will take from 2 – 3 days to install within a property. Our Dublin central heating team will give you an expected install time before the installation procedure begins.


    General speaking, it is recommended that you replace your gas boiler every 15 years. But you may need to replace the gas boiler more often if the boiler is no longer fit to serve the needs of a growing family or if the boiler requires excessive repairs.


    Yes, modern boilers are more efficient for a variety of reasons but mainly because all new gas boilers are condensing boilers. Condensing boilers have a much larger heat exchanger allowing the boiler to recover more heat, and send much cooler gases up the boiler's flue.
    Modern gas boilers provide a direct monetary advantage to homeowners as they use much less energy and are therefore much cheaper to run.
