Determine the heat demand

Determine the heat demand


For any heating system, whether it is a heat pump, gas, electric or pellet boiler, you need to accurately calculate the heat demand. The reason is simple an increase in the capacity of the unit automatically leads to an unreasonable increase in the level of expenditures on its acquisition and operation, while a reduced capacity does not ensure an adequate level of heating at home. Thus, the selection of any heating equipment should start with the calculation of the heat loss of the building and system design.

Choose a heat source

The heat source for the pump can be air, soil, water, wastewater, etc.The conclusion about which particular heat source should be chosen will depend on the following factors. To know more about Värmepump Stockholm, seek help online.

Consider the cost of the heat pump and the costs that require the installation of the collector. Moreover, the magnitude of these costs will depend on where the building is located, where the site for the geofield is located, whether there are water bodies nearby, what level of groundwater, whether any buildings or communications are located in close proximity.

Consideration of important feature

Is there an installed heating system?

By the heating system we mean installed radiators in the rooms, heated floors and other appliances. And here it is required to evaluate the effectiveness of heating systems and heat pump. This efficiency increases with decreasing temperature differences between the heat source and the heating elements. That is why it will be more effective to take advantage of the heat pump in tandem with waterheated floors, than if radiators are used with such a pump.

Is it possible to carry out drilling operations at the site?

A longterm and stable heat source can be provided with a geothermal probe. To carry out work on drilling, you should consider all the factors of a particular place. In particular, it is necessary to relate the capabilities of the drilling rig and the peculiarities of the territory and understand whether drilling is possible in principle here. With the right kind of  Offert Värmepump  this is important.

What is the optimal depth for the geothermal probe?

Features of the geological structure of the site, called geodesy, is a necessary part of the assessment of the situation, which is carried out after calculating how deep the geothermal reservoir should be drilled. Naturally, for each case the depth will be its own, but usually it rarely exceeds one and a half hundred meters. For example, drilling is required to make a total depth of 240 meters. This can be done in several ways

  • make five wells, each of which will be 50 meters deep
  • make six wells, each of which will be 40 meters deep
  • Make eight wells, the depth of each of which will be 30 meters.

Between the collectors must be maintained a safe distance, the minimum value of which is six meters. The cost of drilling will increase in direct proportion to the growth of the depth to which the drilling is done.

Does the plot area meet all the required parameters for laying a horizontal collector?

If the size of the site allows, there is an option to do without drilling. This will require horizontal lying of the collector, however, it should be taken into account to increase the area of ​​such lying and its length this is important because it will be impossible to build anything on this area and you cannot plant trees with deep root system.

Will the heat pump be used as an air conditioner?

To take advantage of this opportunity, you need to considerif pumps of the types “water / water” or “soil / water” are used, then in this case it is possible with savings to use the possibilities of passive coolingif any other types of pumps are used, they will cool in active mode.

Is the ventilation system installed?

If the answer is yes, then this is a great opportunity to integrate a heat pump into it and use the ventilation system as an excellent option for air heating.
