Advantages of Air Source Heat Pumps

A Heat Pump that is Air Source (ASHP) is efficient in cutting costs and reducing carbon emissions when it is constructed to be suitable for space heating in an appropriately-designed structure.

The most important thing is to ensure that the structure is well-insulated (and efficiently managed). New buildings must include high insulation and constructed in a way that will minimize heat loss via air leaks.

Since the ASHP performs better when it produces large amounts of warmth rather than a smaller amount of heat the distribution system within the building must be able to be able to match this: a vast space of heating underfloor that distributes warmth is more effective than a tiny section of radiators that emit high temperatures (and producing drafts).

Coefficient of Performance CoP

The primary factor that determines the effectiveness of a heat pump lies in it’s Coefficient of Performance: the “CoP”. In spite of 1st law of thermodynamics that states that energy is neither produced or destroyed in the same way, an ASHP installed in a well-designed installation could transfer up to three heat units per each unit of electricity used. The heat pump isn’t making this energy, it’s simply separating a medium temperature from the outside air to create warm (which is utilized to heat) in addition to cool (which can be returned to the air).

The CoP will vary for every installation, but the lower the temperature at which the heat distribution system is connected for the system that distributes heat,, the more high the CoP will be. If the output temperature is 60 degrees Celsius, then it is required to heat radiators, the CoP can drop to a value that is just 2.0. If the distribution of heat is to an well-designed underfloor heating system which works effectively with temperatures of 40degC, then the CoP may increase to 3 during winter (and higher in autumn and spring).

The temperature of the input is important for the CoP of the heat pump. The higher the temperature of the input is from air temperatures, the less it is the work that is required by the heat pump, the greater your CoP is likely to be. The most important element will be that of the “uplift” between the temperature of the source and the output temperature. This is why the ASHP ASHP is more effective during the autumn or spring than during the depths of winter.

Benefits of Heat Pumps

Heat pumps can save you money. They cost less to operate as compared to direct electrical heating. They’re less expensive to run than oil boilers and may be more affordable than running gas boilers. Since heat pumps are fully automated, they need less effort than biomass boilers.

Heat pumps reduce carbon emissions. In contrast to burning gas, oil, LPG or biomass, the heat pump does not generate carbon emissions in the vicinity (and there are no carbon emissions in the first place in the event that an energy source that is renewable can be used for powering it).

Heat pumps are efficient and save space. There aren’t any storage requirements for fuel. demands.

Heating systems are secure. There isn’t any combustion and there is no release of gases that could be dangerous. No flues are needed.

They require less maintenance than combustion-based heating systems.

The heat pumps can offer cooling during summer and heating during winter.

Benefits that Air Source Heat pumps offer

The main reason to choose an ASHP instead of an Ground Source Heat Pump (GSHP) is the fact that they’re more affordable and easier to set up, since you can avoid the expense of installing the “ground loop heat exchanger” within the ground.

The disadvantages from Air Source Heat Pumps

An ASHP is not able to access an interseasonal storage of heat within the ground. Therefore, it can’t benefit of the fact that greater temperatures are accessible by the soil in winter, compared to the air around it. Therefore, it is less efficient than ground source heat pumps during winter and has having a lower performance coefficient. It requires energy (and creates noise) using a fan to push air through it’s heat exchangers. It should also incorporate a defrost system to stop ice from forming on the heat exchangers during cold temperatures (when heating is the most required).

The advantages of ground source heat Pumps

The primary benefit of using the GSHP is that the performance coefficient is greater than an ASHP in winter due to the fact that the temperature of the ground is much higher than that of the surrounding air temperature. Planning permission is also much easier because the GSHP can be hidden away from view and produces almost no noise. Because the GSHP is less prone to moving parts it could also have an extended working time.

Benefits of the use of Interseasonal Heat Transfer

The Interseasonal Heat Transfer installation is much better than the without-aided GSHP since IHT systems IHT installation draws warmth from an warmer Thermalbank as opposed to drawing it from the cold ground.
