The war in Afghanistan has cost Britain at least Â£37bn and the figure will rise to a sum equivalent to more than Â£2,000 for every taxpaying household, according to a devastating critique of the UK's role in the conflict. Since 2006, on a conservative estimate, it has cost Â£15m a day to maintain Britain's military presence in Helmand province.
A ducted heat pump can deliver 1.5 to over 3 times more heat energy to a home than the electric energy it consumes. This is possible because a heat pump moves heat from the air rather than converting it from a fuel, like in combustion heating systems.This cycle can be reversed in the summer to cool your home.The mild Pacific Northwest climate provides ideal conditions for high-efficiency heat pumps.1  Save energy and money. 2  If you heat with electricity, a heat pump can reduce the amount of energy you use for heating by as much as 30%-40%.

Geothermal pump systems reach fairly high coefficient of performance (CoP), 3 to 6, on the coldest of winter nights, compared to 1.75-2.5 for air-source heat pumps on cool days. Ground source heat pumps (GSHPs) are among the most energy efficient technologies for providing HVAC and water heating.
