It is not always possible or desirable to place an outdoor unit anywhere. Consider the risk of noise pollution, particularly for neighbors, because of the appearance of the facade, or because there is simply no suitable space to place an outdoor unit. A heat pump that you place entirely indoors is then a godsend. They are also relatively easy and quick to install. These are four monoblock heat pumps intended for indoor installation.
Itho Daalderop Vincent
The Vincent air/water heat pump from Itho Daalderop has an output of 4.5 kW and is available in two variants. The V45 Combi is suitable for heating, cooling and providing hot tap water, while with the V45 Hybrid only heating can be provided.
Through a roof penetration, for example, heat is extracted from or released to the outside air. Return air from a ventilation system can also be connected to the system for additional efficiency. The hybrid version can work with any central heating boiler and with the all-electric variant there is a choice of different WPV storage vessels from Itho Daalderop itself. The refrigerant used is propane (R290).
Etherma Fire+Ice
This modern-looking, unobtrusive air-to-air heat pump from Etherma can be used to both heat and cool a home. It is important to note that this unit must be installed indoors against an exterior vertical wall that has a smooth surface. All necessary penetrations are neatly hidden behind the heat pump housing.
Installation is therefore relatively simple. It mainly comes down to determining the optimal location, drilling two through holes for the supply and removal of outside air, another small one for the removal of condensation, after which the unit is attached to the inside wall and heating and cooling can begin immediately. The installation takes place entirely from the inside.
The heat pump uses refrigerant R32, and at low outdoor temperatures, an integrated auxiliary heating element can assist. However, the Etherma Fire+Ice is intended for small houses and apartments up to about 35 square meters. A heat pump boiler is additionally required for hot tap water.
Triple Solar
This is a 3.5 kW PVT heat pump and is suitable for hybrid or all-electric use. It is, however, a brine-to-water heat pump that must be combined with Triple Solar's PVT panels and can then be used for heating, cooling and hot tap water. Thanks to the combination with PVT panels, heat and power are gained at the same time, and that with only panels on the roof. The lack of moving parts makes the indoor unit very compact, quiet and low maintenance.
Propane (R290) is used as the refrigerant. Expanding to serve as a fully all-elecric version is easily arranged by combining the heat pump with Triple Solar's thermal battery. The heat stored in it can then be used to provide hot tap water at any time. This particular thermal battery is up to four times smaller than a traditional hot water cylinder, in part because the heating element is already present in the PVT heat pump itself.
Alpha Innotec Paros 4
This 4 kW air-to-water heat pump also requires two ducts for the supply and return of outside air. These can be wall ducts for first floor installation in a garage or utility room, for example, or two roof ducts or two wall ducts for attic installation. If roof penetrations are used, an attractively designed heat pump chimney can also be chosen.
This quiet heat pump can provide heating, cooling and domestic hot water. Again, it is intended for existing buildings and new construction, as it can be placed in both hybrid and all-electric setups. The refrigerant R454B used has a considerably lower GWP than older refrigerants such as R410A. A tower arrangement is possible in which everything, including a buffer tank, is integrated. It is also possible to work with separate components, which is particularly useful if customization is required.
