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%.

In fact heat pumps are so efficient that typically, 1kW of electrical energy you put in, your heat pump will produce around 4kW of heat energy out. This efficiency is represented as a COP (Coefficient of Performance), a good heat pump, operated correctly will have a COP of around 4.n fact heat pumps are so efficient that typically, 1kW of electrical energy you put in, your heat pump will produce around 4kW of heat energy out.
