VentHeat, a new Irish company specialising in the supply of heating, ventilation and air conditioning systems for passive house and low energy buildings, has launched the Pichler PKOM4 compact heat pump system to the Irish market. The system combines heating, cooling, ventilation and domestic hot water in one passive house certified unit with a footprint of less than 0.75 m2. A stand out feature is that in Combi mode, both compressors work in parallel to deliver space heating and domestic hot water. The PKOM4 is Smart Grid Ready utilising smart grid electricity or on-site renewable energy to boost domestic hot water to a higher temperature via an immersion heater. Integration and control of additional electrical heating sources (underfloor heating for bathroom, or infra-red panel) is possible. VentHeat explained that the system can also be linked into in smart home and central building management systems, with control by a smart phone/ tablet app. Ventheat also supply the Pichler range of standalone MVHR systems, including its LG 1000 unit with VAV box for sound absorption and volume flow control, which won first place in the 2016 Passive House Institute component awards.
