A heat ticker is , essentially , an inverted cooling machine . Using electrical energy , the system generate heat , which is very welcome for glasshouse agriculturist . During Strawberry Day , Erik Bax delved deeper into the system , which , when used aright , he believes to be much more effective than the democratic atomic number 99 - kettle . " A heat pump is suitable for many situations . It help oneself render a answer to the energy problem , " says the Energy and CO2 Emission Advisor .
In his presentation on January 10 , Erik in short touched on some well - know political decisions . " grower still have clip now , but in two years , the situation will get serious . " He is referring to the costs of accelerator pedal usage , among other things . Strawberry growers sometimes face an extra challenge equate to other greenhouse producers . strawberry mark glasshouse are often site in isolated topographic point , not in greenhouse bunch with better base . Therefore , they ca n’t just link up to a source of geothermic or residuary heat . " If outside hotness sources are lacking , the heat pump quickly comes into play . " This allows them to produce their own heat .

EfficiencyA crucial term for the usage of a heat pump is the presence of an muscularity seed . The system ferment on electricity . Moreover , an vim root is needed to ' harvest ' the warmth . This can be pee , atmosphere , or residual heat . When harvesting estrus , the COP value is of import . The acronym , which stands for Coefficient of Performance , allow us to compare systems based on their vigor public presentation . The COP note value bespeak the ratio between the electrical energy involve for the heating system pump and the amount of heat it publish . " The higher the COP economic value , the more efficient the warmth pump is . "
It ’s crucial to use the heat pump right . If a user fail to do so , the system ’s electricity white plague promptly increases . " determine out when the temperature difference between the evaporator and the condenser is too high . " There are different types of heat pumps . Air - to - water system heat pump are often adapted to already survive environment . A disadvantage of this technique , harmonize to him , is the down in the mouth COP value , which result in " it requiring more electricity , compared to a body of water - to - heat heat pump . "

Comparison with boilerDuring Strawberry Day , Erik instance with an representative of how the organisation can work ( graphical representation below ) . He did this for an electricity - powered condensation heat pump , which generates estrus tantamount to 1 three-dimensional meter of flatulence with an input of 2 kW - hours of energy . That three-dimensional meter of gas is equal to 8.79 kilowatt - hours of heat .
Many strawberry mark growers still heat up their greenhouses with gas - powered boilers . Erik explicate how a heat pump becomes more profitable in the tenacious trial , part due to new taxis . " In 2024 , a heat pump is still more expensive , but by 2030 , the balance will have bung in favor of the high temperature pump . The tipping gunpoint is somewhere in between . "

A oestrus pump is part of the solutionIn gardening , a heat pump is part of the solution . It combines well with other systems . Erik mentioned the combination with heat - frigid storage at Van der Avoird Trayplant . With heat - cold store , warm water supply at a temperature of up to 25 degrees Celsius is often earmark to remain in the ground . " A higher temperature would be better , but that ’s often not reserve in the permit . "
When using heat - cold store , it ’s important for growers to take a just look at their heating plant organization . It must be suitable for low - temperature warmth . In exercise , this often means more heating pipes .
Another selection is for the heating system ticker to be used in compounding with aquathermy . Koppert Cress is a well - known user of this . In this case , the warmth ticker harvest heating from airfoil piddle .
Dehumidification is also often in the word with the rising slope of LED ignition . Some dehumidification systems also have a built - in heat pump , aver Erik . He mentions the DryGair system of rules as an instance . " That ’s a kind of airwave - to - water oestrus ticker . "
Example of gentle wind - to - warmth heat ticker . Erik does n’t have hardheaded lesson from horticulture yet .
Call to ActionMany growers wo n’t be chop-chop convert to put in a heat ticker , says Erik . Therefore , he conceive that it ’s often wise to first critically examine a troupe ’s passion requirement and slim down it where possible . This way , a possible warmth heart can later cover a larger part of that heating plant demand . He calls for attempts to be made at get a painting of the energy situation in the futurity . " It ’s good that agriculturalist have been given a bite more time to take beat . "
