Heating case study: converting gas to heat pump hydronic

This 1908 weatherboard Edwardian in Melbourne has been renovated, extended and insulated — and is making the switch to all-electric, powered by solar PV and 100% GreenPower.

In a project completed in November 2017, the owners replaced the gas boiler on their existing hydronic heating system with an electric heat pump, while retaining the original 25-year-old radiators.
