When it comes to heating the home, we all want to get the maximum amount of warmth for the minimum amount of pennies. Living in Scotland can be a cold affair even in the warmest of months, so anything that makes the climate a bit more bearable while still being cheap is a gift from the heavens.
For homeowners, one lovely little piece of applied thermodynamics that meets both these requirements in the heat pump. Heat pumps glasgow are based of clever use of physical sciences to move thermal energy from a cooler environment to a warmer one, with the warmer being known as the “heat sink”. Most heat pumps are vapour-compression refrigeration devices. As may be apparent, their science shares much in common with refrigerators.
How They Work
With regards to heat pumps, Scotland is a country perfect for their application. With a high demand for central heating – and as a result high energy bills – heat pumps can save households a huge amount of money of their lifespan. A standard heat pump has a lifespan of 20 years and a low installation cost in comparison to other money saving installations.
There are a variety of different heat pumps techniques available, but the majority of those available to homeowners are vapour-compression heat pumps. They are based around a fairly simple physical principle: heat will move from areas of higher temperatures to those of lower temperatures. By manipulating certain aspects of the physical situation, heat pumps can draw heat from the surrounding air which is then used to vapourise water or another similar heat transfer liquid. The resulting vapour is compressed, increasing its temperature, and sent to a condenser in the appropriate area. The heat is then extracted from the compressed vapour, causing the fluid to revert to its liquid form. It is then passed back to the evaporator to complete the cycle.
How They Save You Money
Why this is cheaper is simple: only a little electricity is used to make this whole cycle work. The majority of the energy required for the cycle is low-grade ambient heat energy, which is free. Standard electrical resistance heaters have a COP (coefficient of performance) rating of 1. For every unit of energy they require to operate, you receive one unit of heat. Heat pumps have a COP rating of 3 to 4, making them far more effective heaters.
The average annual energy bill for a medium sized house is £1,066, with a large portion of that coming from the cost of heating the home. Pricing for air source heat pumps starts at around £400, although they can be more expensive than this. Once installed, air source heat pumps can cut costs by up to 65%, meaning the bill would drop to a mere £373.10 annually. Over the lifespan of the 20 years, that’s a saving of £7,462.
On top of this, there is the Renewable Heat Incentive, or RHI. The RHI is a scheme set up by the UK government to assist them reaching their target of 12% of all heating coming from renewable sources by 2020. The RHI works by providing quarterly payments to houses installing renewable technologies. An average quarterly payment is around £170, giving an annual payout of £680.
