Heat pumps utilizing ambient air as the source of energy are the most technically advanced products of PZP KOMPLET. Competitively priced they can be characterised by their performance and ease of installation. They can be used not only for heating and hot water production but they are equally suitable for swimming pools heating. The HPAW split system heat pump with its external evaporator unit can be used in all types of house and commercial applications and is suitable for radiator, floor or wall heating. The HPAW heat pumps consist of two parts which are connected to each other on site.
The internal part comprising compressor, condenser, water heater, control system, control panel and other heat pump components should be situated in a suitable internal space; a utility room, garage, or plant room are the typical locations. The internal part is equipped with the necessary fittings to enable connection to the external part or the heating system. All the components are set in an acoustically insulated casing.
- the heat pump evaporator should be positioned outside the building in a convenient location not too far way from the internal unit. The location must ensure a free flow of air through the evaporator and be able to drain the water freezing on the evaporator that melts away during an ice de-frosting cycle. Air flow through the evaporator is maintained using two-stage ultrasilent fans of high performance. The external parts are made of corrosion resistant materials and require no further protection from the weather.
- especially suitable for connection to an existing gas or oil boiler. Although this model is essentially the same as the HPAW heat pump, it is equipped with a weather compensated controller and an option to control independently up to three heating circuits. The 06 SB to 18 SB types are furthermore equipped with a circulation pump as a standard. Due to its simple but smart control it is for example possible to connect an existing gas or oil boiler to the heat pump. In this configuration the heat pump operates as the main heat source and the boiler becomes a supplementary or standby heat source.
- enables connection of an external electric boiler As well as the SB model features, the SC model of the HBAW heat pump series enables direct connection of electric immersion heaters that can be fitted in either a hot water cylinder or buffer tank. The heat pump control system can provide automatic three stage control of the external immersion heaters. Moreover, the SC model is equipped with special functions for hot water preparation, connection to combined rating systems and the like.
- a compact heat pump for easy installation. The SE model offers maximum connection options and comfort. As well as the equipment of the SB and SC models, it comes as completed by its own electric boiler which can be used as a supplementary heat source. A three-way distributing valve for heating / hot water preparation is also supplied as standard. The use of this function enables preparation of domestic hot water in special cylinders. With its compact design and factory fitted components considerable labour and material savings are possible when type SE appliances are specified.
From the very beginning of PZP heat pump manufacturing, we have been convinced that the air-water heat pump of the Split type represents the most suitable solution and we recommend it to all those interested in heating by means of a heat pump.
