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%. 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%. 3  Comfort. 4  Heat pumps deliver constant, even temperatures and also balance humidity.
As it turns out, a heat pump can both heat and cool, and in some applications, it's preferred to separate heating and cooling systems. Simply put, a heat pump is a device that uses a small amount of energy to move heat from one location to another. Not too difficult, right? Heat pumps are typically used to pull heat out of the air or ground to heat a home or office building, but they can be reversed to cool a building. In a way, if you know how an air conditioner works, then you already know a lot about how a heat pump works. This is because heat pumps and air conditioners operate in a very similar way.
