About me
We do not fly, nor have a car and in working to eliminate our use of fossil fuels have converted our old 'leaky' uninsulated family home to be fossil fuel free with a newer generation high temp. r290 ASHP, working with a PV array

About this property

London, SW8

3 bedrooms

Air source heat pump

Installed by NP Trading

Installing the system

An 1860s property with uninsulated solid wall & uninsulated roof construction in a conservation area having an open plan arrangement over 4 floors with 3 occupants. System comprising - Trianco 22kW ASHP raised c.1.8m above external ground level, Sunamp 310 xPlus thermal store, 12 panel PV array, solar diverter, battery ready to follow on commercial release of more sustainable batteries (sodium or eq.) with no radiators changed. The calculated heat loss placed the required heat pump mid way above commonly available output ranges & below the 22kW max. sys capacity.

Living with a heat pump

Quieter than our old gas boiler, effective & efficient. Ensuring electronics, apps & system ommunication were fully integrated for operation took longer than anticipated.
