The Story

Joanne says ‘When we started to plan for the extension we decided we wanted to make the house more energy efficient to help lower our heating bills. We were unable to hold any consistent temperature in the house.  When the heating was on it was roasting and once turned off, in a short time the house was freezing again. The condensation was really bad every morning.  We had heard about the air to water system from other people who had it.  We looked into it and realized we would be eligible for an SEAI grant.’

The Measures

Their retrofit included:

• Air source heat pump as the primary heating system
• Airtightness level brought to less than 5 air changes-per-hour to reduce draughts
• Advanced demand-controlled ventilation for fresh and healthy indoor air quality
• Attic Insulation
• External wall insulation
• Double glazed windows to achieve a U-Value of 1.2w/m2k
• Underfloor heating
• High Efficiency Stove
• 2kw Solar PV System (8 panel) on the south facing façade

The Results

The Clarkes home reached an A2 BER , ensuring it has healthy indoor air quality and consistently warm living spaces 24 hours a day.  Air tightness measures had to be addressed to guarantee the efficient operation of the heat pump and the intelligent ventilation system was installed.

Joanne says ‘The contractors were great from the very start explaining each step and timelines involved and were very easy to work with. We would definitely have no hesitation in recommending them. We have noticed a big difference in the house. The heat is constant not fluctuating, no condensation and we always have hot water. We’re delighted with the upgrades to the house. Electric Ireland Superhomes made it a seamless and enjoyable experience’.
