Best Heat Pump


With the price of energy soaring sky high and with the austerity budgets of recent years, you will want to know how to choose the best heat pump to enable you to make savings on your energy bills. Choosing the right heat pump will allow you to save up to thirty percent on your energy usage for heating the home.

In simple terms, a heat pump moves heat from one source and transfers it into your home. Hot air can further be moved to other rooms in the home and maintain a constant comfortable temperature. This constancy in temperature combined with a well-insulated home is the key to maximising energy efficiency and cost savings.

Heat pumps use nature as the source of fuel, which means there are three sources they can use. Which one is suitable for your home depends on your location and how much you space have available for installation.

What Type of Heating Systems Can I Use With a Heat Pump?

One type of heat pump, the air source heat pump, takes external air and distributes it to heat radiators, convection systems, under floor heating systems and hot water. The technology is similar to how a fridge works when it is absorbing warm air from the refrigerator which cools the fridge. Feel behind your refrigerator and you notice the warm air that has been extracted. This same principle is how air source heat pumps work.

Air to water heat pump systems channel heat distribution through your existing wet central heating system. As heat pumps work more effectively at lower temperatures, energy savings are made. There is some environmental impact as with any kind of system, that uses electricity but the fuel source is provided by nature in the form of air or water thus avoiding the use of fossil fuels.

How Heat Pumps Work

Thinking about the surface of the earth, it is clear to see it is one massive collector that absorbs radiation from the sun. In the UK the below ground temperature is fairly constant between 11 to 13 degrees centigrade a few metres down. Heat pumps use this to advantage by the transfer of the stored heat from the earth or in fact, ground water to buildings for warmth and effect the opposite in warm weather when cooling is provided.

By the use of compression, the heat is pumped up at a low temperature, and then released at higher temperatures so that it can be re-used. A heat pump looks very similar to conventional oil or gas boilers and performs the same functions of heating water and keeping homes warm.

The great revelation about heat pumps is that for each electricity unit used to work the heat pump, as many as four units of heat are generated. As can be clearly seen, this 1 to 4 ratio gives incredible value for your electricity consumption giving you 30% more heating for the same or less power usage.

The operation of the heat pumps vary slightly and a ground source heat pump uses closed loop technology, which is a system of antifreeze and water to collect heat from the soil.

Air and water heat pumps collect heat from external air. Usually there are moderate air temperatures in the UK but during heat collection, there is an element of natural icing of the air heat exchanger. This causes small amounts of electricity to be used for defrosting.

Water heat pumps use an available water source such as a river or well as a heat source. The technology used is an open loop system and the water is passed through and discarded unlike the closed loop system.

Knowing how a heat pump works helps to understand the best heat pump option for your home. With the assistance of a professional air conditioning company with qualified engineers on hand to advise you, there will be no issues. Heat pumps come in many different sizes and it is necessary to install one that is the correct size for the room you want to heat by or for the entire property.

Installation of a Domestic Heat Pump

There are three main components to the system, the heat pump, heat distribution system, and pipes in the ground. A trench is dug horizontally for the pipes to be laid or they are buried in a borehole near the house. Depending on the temperature, fluid will either absorb heat or emit heat to the soil. In wintertime the heat pump removes the heat from the fluid and makes it a higher temperature for use inside the building, often under floor heating. The distribution system will transfer the extracted ground heat in a system of this type and is suitable for a radiator system as well.

The best heat pump is the one that is the right size for your home, fits in with your surroundings, gives you energy savings and reduces your impact on the environment. It is the pinnacle of resourceful heating in temperate climates like the UK and has the added advantage of cooling the home as well in the summer months, if extremes of temperature are experienced, keeping a comfortable ambient temperature at all times. Heat pumps are much more cost-effective then other conventional heating devices

We would always recommend a reliable manufacturer that has been at the forefront of research and development in this area and we stock Daikin and Fujitsu to name two of our personal recommendations for this type of heating system. Although there will be a payback period before you start making savings after investment in the system, you will never have to worry about oil or other kinds of fuel to run your heating system and you will be heating your home in a more natural, efficient and appropriate way.
