Heat Pumps are normally classified by their heat source and means of delivering the heat: Air to Air : Heat pump where the collecting medium is air and the destination medium is also air. Generally, most commercial small split and
What Makes Heat Pumps Better Than Solar Water Heaters?
New customers are often confused by the comparison and selection between heat pumps and solar water heaters. They are often asked such questions by their technical’s. Why should I choose heat pumps rather than solar? What’s the advantages of heat
Can money be saved as well?
Yes of course. Due to the dynamic nature of Heat Pumps their capital cost is higher than conventional heating systems, however, the savings delivered in energy efficiency allows for very low operating costs. When utilized in commercial buildings that also
So they save energy but what about CO2 Emissions?
Heat Pumps emit considerably less CO2 to the atmosphere than gas or oil fired heating systems so they are environment friendly and the low grade heat source utilized is considered to be a renewable energy source (CO2 reduction is generally proportional to
How do you calculate a COP?
In its simplest form this relates to HEATING OUTPUT divided by the POWER INPUT E.g. with a COP of say 4 to 1 the HEATING OUTPUT relates to 4 Kw and the POWER INPUT 1 KW. Note: Remember that COPs
What sort of efficiencies heat pump can produce?
Depending on the application and type of Heat Pump utilized efficiencies of 300% to 500% are normal. When dealing with Heat Pumps efficiency is known as Coefficient of Performance (COP), so the COPs for the above example would be 3
Why is this remarkable?
The thermodynamic cycle occurs at constant energy content throughout even though the temperature has been increased from say 5ºC to say 35ºC. A refrigerant is utilized in the cycle to act as the transfer medium and the only prime energy
How does heat pump work?
The vast majority of Heat Pumps work on the same principle as the domestic refrigerator utilizing a vapour compression cycle but for heating the Heat Pump utilizes the ‘hot end’ of the process. The vapour compression process utilizes low grade
What is a Heat Pump?
Heat pump is a device for transferring energy in the form of useful heat from one place to another. It cannot store, make or destroy heat energy – it simply moves it. There are a number of techniques that exploit
