Location: 

Glanmire, Cork, Ireland

A new housing development consisting of over 600 A-rated, low energy, low CO2 houses is now under way in Glanmire, Co. Cork with development and construction being carried out by the O’ Flynn Group. The Ballinglanna development contains a mix of 2, 3 and 4 bedroom houses, with an emphasis on high quality design and finishes throughout. It includes innovative and modern heating system with high levels of insulation which, with the use of renewable energy from quality construction methods, will provide maximum comfort throughout all seasons. Pipelife Ireland will supply the full heating system consisting of the Hitachi Yutaki Air-To-Water Heat Pump and Underfloor Heating for this development.

The central heating system is a modern Hitachi air source heat pump. The system provides energy efficient and responsive central heating and large capacity hot water storage. Pipelife Ireland’s new Qual-Pex Plus+ ‘Easy-Lay’ Multilayer Pipe will be installed for the Underfloor Heating on the ground floor with High output radiators on the first floor areas. These will work in conjunction with modern zoned heating controls.

The Yutaki SCombi air source heat pump provides energy-efficient and responsive central heating and large capacity hot water storage to serve underfloor heating on the ground floor, with high output radiators on the first floor areas combined with modern zoned heating controls and, due to the restricted installation space, was a perfect solution for this project.

Declan Kiely of Pat Kiely Plumbing & Heating commented:

“We have a long relationship with Pipelife going back to the early days when they first introduced underfloor heating to the Irish market. We have installed the Hitachi Yutaki Heat Pump on other sites and so we where happy to go with this unit for this development as well. I know that when I install a Hitachi Yutaki Heat Pump that I am installing a quality product manufactured by a trusted leader. This allows me to install with more confidence.”

Padjoe Barry, National Sales Manager at Pipelife says:

“We believe in providing our customers with a one-stop-shop for complete package solutions. From our design indemnity insurance through top quality materials to comprehensive before and after sales technical support we continue to offer an industry leading service allowing our customers to purchase with confidence.”
