Smiths, Ardmore – Retrofit

This installation was a retrofit project for a detached two-story home 250m2. The installation comprised of underfloor heating, heat pump, and solar PV. The 3.3kw solar PV system helps to offset the electrical running costs of the heat pump system throughout the year, with an estimated overall saving of 30%.
