Some things we still want to investigate and / or do

Solar warm air - we are interested in importing passive solar heating into the house to supplement gas boiler heating. One product we have considered is SolarVenti.

Wireless thermostat for central heating boiler - this could be moved from room to room to give greater flexibility over temperature control.

More PV and Air Source Heat Pump - this has replaced solar warm air as a project to investigate

Insulate kitchen floor

Draughts - heat loss through draughts is a significant problem in an old house. We've carried out some experiments on infiltration (otherwise known as draughts). More information
