Two storey house on 211 m2 built as nZEB building

Nilan Compact P

Builder Brendan Murphy started a project to self-build a Passive House in 2010. This was long before the concept had become trendy. He chose not to use a hydronic heating system.

Instead, the Compact P ventilation system heats the dwelling by heating the supply air via an integral air source heat pump. An after-heating element of 2 kW has been installed, but it has not yet been necessary to use it.

In addition to heating the supply air, Compact P also produces enough domestic hot water to meet the requirements of the family.

Brendan Murphy was one of the first people to install a Compact P unit in Ireland, but it is now a natural choice of installation in most Passive Houses.

Nilan’s Compact P unit was chosen because the energy from the extract air can be utilised to produce domestic hot water.

Compact P can also heat the supply air and thereby help heat the dwelling.

Compact P has a reversible cooling circuit and in the summer it can cool the supply air. When it cools the supply air, the heat is transferred to the domestic hot water so that no energy is wasted.
