Better Energy Homes Scheme.

Under the Better Energy Homes Scheme Homeowners that make energy efficient improvements may be entitled to a grant.

If you would like to know more, we can arrange for an energy advisor to contact you to discuss your proposed energy improvements. 


Grant approval in minutes, simple and straight forward online grant application all you need is your MPRN Number (Can Be Found on Electricity Bill).


To verify your homes suitability a home survey may be required(This is a FREE heating survey) after which you will receive a fixed price quotation.


Our team of trained installers will have your new energy efficient improvements installed with minimal disruption so you can soon enjoy the benefits.

Who Qualifies for an SEAI Grant.

The grant is available through the SEAI Better Energy Homes Scheme. The scheme is open to homes built and inhabited before 2006 for Heating controls upgrade and Insulation grant and from 2011 for all other grants. Under the scheme Homeowners, landlords and property owners can apply for the available grants when making energy improvements to their property.

Application can be made through the SEAI website or alternatively contact the Gasworks team and we can apply on your behalf.

The SEAI Grants available in 2020. 

The Sustainable Energy Authority of Ireland or SEAI is Irelands national energy authority, they provide Grants to improve your homes energy efficiency. These Include: 

  • Heating Controls  
  • Solar Thermal 
  • Heat Pump 
  • Solar PV 
  • Insulation 

SEAI Boiler Grant. 

Before April 2018 homeowners who upgraded their boiler to a high efficiency model could take advantage of an SEAI boiler grant. Although the grant was primarily for upgrading your boiler, it was also a requirement to upgrade your homes heating controls as part of the boiler installation. 

As part of Irelands commitment to increasing our renewable energy's the SEAI boiler grant has been discontinued. Because of a boiler's reliance on fossil fuels it makes sense to cease any associated grants. 

The SEAI Boiler grant has since been replaced with the Heating Controls Upgrade grant. The Grant is available to the owners of property's built and occupied before 2006. 

SEAI Heating Controls Upgrade Grant.

Get more control, more home comfort and more efficiency with a heating controls upgrade. Reduce you heating bill by up to 20% and receive an SEAI Grant of 700 towards the cost. Since the SEAI Boiler Grant has ended, there is no need to replace your boiler when upgrading your heating controls.

The correct heating controls will give you the ability to heat your home when needed and to a specific temperature. For a typical central heating system with a hot water cylinder, heating controls will at a minimum consist of independent heating control and independent hot water control. This is achieved using a 2-channel timer, a room thermostat, hot water cylinder thermostat and thermostatic radiator valves.  

This level of control allows us to turn on the radiators without the water heating up and to heat the hot water (using gas/oil boiler not electric immersion) without the radiators heating up. This is of particular benefit in the summer months when demand for space heating is at its lowest. 

Typically, the average home will have 1 heating zone and 1 hot water zone. The room thermostat will normally be located in the main living area or hall, with Thermostatic Radiator Valves (TRV’s) fitted to the bedroom radiators. The hot water cylinder will be temperature controlled to a minimum of 60°C. This inhibits the growth of bacteria such as legionella.  

Larger homes may require a greater level of control and will usually have more than one central heating zone such as upstairs radiators, downstairs radiators and hot water (3 channel timer). 

Poorly controlled central heating systems are wasteful of energy and more expensive to operate. If you would like to discuss a heating controls upgrade or speak to an expert energy advisor please don’t hesitate to contact the Gasworks Team. 

Required Heating Controls 

Some of the heating controls that will be installed as part of any SEAI Boiler grant.

Thermostatic radiator valves (TRV's) are mechanical thermostats that are used to control the air temperature in the rooms in which they are fitted (they do not control the boiler). TRV's work by reducing the flow of water through the radiator to achieve the desired temperature.

They can be of particular use in bedrooms which will require a lower room temperatures to maintain comfort levels. When used correctly TRV's can result in savings of up to 10%. Because TRV,s are fitted to the side of a radiator careful consideration must be given curtains, coverings and any furniture which may impact on the free movement of air. Poorly located TRV's can significantly reduce their effectiveness and quickly remove any advantage you might have otherwise gained.

Used to control the air temperature inside the property, your room thermostat will normally be set between 18°C and 21°C. It is important to remember the lower the required temperature the lower your bills will be.

Room thermostats work by turning the boiler on and off to achieve the required temperature, during heating on periods. This regulation of temperature will make your heating more manageable and your home more comfortable.

It is important to locate room thermostats away from draughts (wall vents), direct sunlight and sources of heat such as close to or above a radiator, open fires, gas fires, stoves, and cookers.

The hot water cylinder thermostat controls the temperature of your stored hot water. The hot water cylinder stat will be normally mounted to the side of the hot water cylinder ⅓ of the way up. It is strongly advised to have the cylinder thermostat set to a minimum of 60°C with a maximum advisable temperature of 65°C. This is to minimise the risk of severe scalding and inhibit the growth of any bacteria within the cylinder.

If you have a gas or oil boiler you will have at least some form of basic programmer at minimum, which is used to turn on/off your central heating as needed. The 7 day programmer will have additional features and benefits for greater flexibility. Choose from daily or weekly central heating schedules so you can best suit even the most outrageous of work/home lifestyles.

Multiple zones coupled with correct central heating system zoning allows for complete independent heating and hot water schedules.


If you have an electric immersion you will need an immersion timer installed as part of your new boiler grant. The immersion timer is used to control the duration of time the immersion is on/off. It gives the homeowner greater control over water heating and reduces any periods where the immersion has been left on accidentally.


Boiler interlock is not an actual device, but refers to when the boiler fires only when there is demand for heat from a thermostat. If there is no demand from a thermostat the boiler will not fire. For example;

Room Thermostat set to 20°C - Actual temperature 20.5°C  = Boiler off

Room Thermostat set to 20°C - Actual temperature 19.5°C  = Boiler on

The boiler will on come on when the target temperature is above the current temperature
