Combination Boilers Combination (Combi) boilers are capable of providing instant hot water and heating while saving space within a home. Combi boilers are acceptable under the Better Energy Homes Heating Controls with Boiler (Oil or Gas) Upgrade. A 24/7 heating programmers, room stat and TRVs are required when installing a Combi boiler as part of the Better Energy Homes Heating Controls with Boiler (Oil or Gas) Upgrade. For Combi boilers a boiler interlock is usually achieved by using a room thermostat, please check with the boiler manufacturer that an interlock is installed within the boiler.
TGD Part J of the Building Regulations 2014 was released this year. All contractors should familiarise themselves with the regulation. Part J can be downloaded from the following link: http://www.environ.ie/en/Publications/Developmen tandHousing/BuildingStandards/FileDownLoad,3724 0,en.pdf
Reminder of Electrical Works Earthing and Bonding must be in accordance with current ETCI (Electro Technical Council of Ireland) National Wiring Rules. A guidance note for Electrical works associated with the Better Energy Homes scheme has been issued at the following address http://www.seai.ie/Grants/Better_energy_homes/c ontractor/Newsletter/Important_guidance_note_for _Electrical_works_associated_with_BEH.pdf. Where the earthing/bonding is below the current ETCI National Wiring Rules an ‘Electrical safety notice to the home owner’ http://www.seai.ie/Grants/Better_energy_homes/c ontractor/Newsletter/Electrical_safety_notice_to_th e_home_owner.pdf shall be issued to notify the home owner that their current wiring installation is not to current ETCI rules.
Renewable Installers Register Analogue heating programmer (time clock) Analogue heating programmers are acceptable under the Better Energy Homes Heating Controls with Boiler (Oil or Gas) and Heating Controls Upgrade only. The programmer must have a 24 hour 7 day function.

SEAI are mandated to develop and maintain a 'Renewable Installers Register' in line with certain requirements of the EU Directive 2009/28/EC on the promotion of the use of energy from renewable sources. The register provides the details of suitably qualified Installers of the following technologies: Small-scale biomass boilers and stoves, Solar photovoltaic, Solar thermal systems (Solar Water Heating), Shallow geothermal systems and Heat Pumps.
The objectives of the Renewable Installers Register are to: - Support homeowners in selecting suitability qualified installers of certain renewable technologies, - Reduce energy use, costs and greenhouse gas emissions - Build market capacity and competence by driving contractor training standards Working towards reaching common ground for the certification of installers of Renewable Energy Technologies through the EU member states.
This Calculator is for the purposes of ensuring that the proposed installation meets the minimum performance requirements of the Better Energy Homes scheme. It is a Microsoft Excel version of the solar contribution formula included in DEAP. It is not a solar installation design tool or sizing calculator. Please note that this should be used in conjunction with the technical guidance note above. It is very important that before a system is sold to a homeowner, or a contract of works is entered into, that the proposed system is compliant with the grant scheme requirements. The above calculation must be done to ensure that the system is sufficiently sized to attract the grant, where the contractor knows or expects that the homeowner has applied for a solar grant.
Inclusion on the Renewable Installers Register does not confer eligibility for undertaking works on grant schemes.
Serious sanctions apply to contractors who fail to adequately advise homeowners of the solar installation performance requirements to enable a homeowner claim a grant or where it is found that
The Better Energy Homes scheme operates a separate registered contractor list with separate Terms and Conditions for registration. For further details on the Better Energy Homes scheme please click on the link below:
S.R. 54:2014 Code of Practice- methodology for the energy efficient retrofit of existing dwellings
http://www.seai.ie/Grants/Better_energy_homes/ Please click on the link below to view the list of known registered installers of small scale renewable technologies: www.seai.ie/renewableinstallersregister See more at: http://www.seai.ie/Renewables/Renewable_Installe rs_Register/
Available to download free of charge from: NSAI Standards This Standard Recommendation has been developed by the Department of the Environment, Community and Local Government, the Department of Communications, Energy and Natural Resources, the Sustainable Energy Authority of Ireland and the National Standards Authority of Ireland in conjunction with the Building Research Establishment to provide guidance on the energy efficient retrofit of dwellings.
Solar Compliance Note and Calculator SEAI has prepared additional technical support for solar installers. These are available on our website. The technical support is in two parts; A technical guidance note http://www.seai.ie/Grants/Better_energy_homes/c ontractor/Newsletter/Solar_Installers_Note.pdf setting out the calculation methodology for achieving compliance with the solar grant scheme requirements and A Solar Hot Water Compliance Calculator http://www.seai.ie/Grants/Better_energy_homes/c ontractor/Newsletter/ to assist with the specification of works to meet the BEH grants requirements.
Technical guidance is provided on the energy efficient retrofit of dwellings having particular regard to fabric and building services, the application of retrofit measures on a whole dwelling basis, general building science and the management of retrofit projects in respect of dwellings. The intended audience for this Standard Recommendation are property managers, designers, specifiers and installers working on energy efficient retrofit projects for dwellings. This document would be of interest to any party considering a retrofit project as well as those in the education sector.
