![]() Heat pump with boiler as backup in simultaneous operationįinally, if you still want to keep your boiler in case the cold weather hits hard in your area, in order to avoid the use of an electric resistance that consumes too much energy, then you can consider this scheme.Īnd if we decide to add the production of domestic hot water, the diagram becomes : ![]() Interesting point: the decoupling cylinder can be replaced by a simple bypass: in this case the diagram would take the following form In the context of this scheme, it is associated with a 2-pipe buffer tank whose role is to ensure a minimum volume of water for the homogeneous operation of the heat pump in order to avoid untimely compressor start-ups. The role of the decoupling cylinder is to make the primary circuit independent from the secondary circuit. This is generally preferred if you are installing a heat pump on several hydraulic circuits with different emitters and temperature levels. The 4-pipe system also makes it possible to connect several circuits with different emitters and therefore different temperatures.įor more information on the physical phenomena inside a buffer tank, see the document linked above.ĭiagram of an air-to-water heat pump installation with a decoupling cylinder. In this diagram we imagine an installation with hot water radiators. 3-way valve with actuator, which passes either through the DHW tank or the buffer tank.This was added to take into account the domestic hot water: On the other hand, if you want to add the domestic hot water tank to your system, then here is the correct diagram (with one hydraulic circuit): This is the scheme that should then be considered However, this assembly allows 2 tappings to be used, with another configuration, to connect several hydraulic distribution circuits whose emitters are the same (example: two separate circuits of floor heating) To learn more about what happens in the buffer tanks, RAGE has also produced an interesting theoretical document to explain the physical hydraulic phenomena within these central elements of the hydraulic circuits in individual housing. In this case, just an underfloor heating system (but not yet radiators with different temperatures) This diagram is only valid if the emitters (hydraulic floor heating) are all the same. The buffer tank, which allows the heat pump to operate correctly, has two connections. Well adapted to an underfloor heating circuit, we find all the elements necessary for the good hydraulic functioning of your heating installation by heat pump on underfloor heating. We will talk about the 4 most important ones: Heat pump with two-way buffer volume It dates from 2013 but heating is not a world that evolves very quickly, and the hydraulic principles remain unchanged. Grenelle Environnement air/water heat pump installation diagramįirst, to have access to basic diagrams, for understanding and organization of the different hydraulic connections or other elements, you can consult the different cases of the Grenelle Environment diagram. If you have some basic knowledge of heating or hydraulics, you will be able to understand and be inspired by them. Generally heat pump manufacturers are a good way to get free heat pump schematics to install. In this article, we will look at different resources that can help you find the right scheme to install your Air to Water heat pump. If you decide to install your heat pump yourself, because all the heat pump installation estimates were too expensive, for example, then you may quickly need a heat pump installation diagram or even several air-to-water heat pump installation diagrams, in order to cross-check the information and manage to make a correct installation at home.
