Genvex Combi 185 ApplianceThe award winning Pichler PKOM 4 (2018) and Genvex Combi 185 (2013) systems provide balanced whole house ventilation, incorporating a high performance counter-flow heat exchanger to recover the heat otherwise lost via the exhaust air. This negates the use of trickle vents, preventing cold draughts from being drawn into habitable rooms. In addition to this heat recovery ventilation they can also provide space heating to the supply rooms and heat up a tank of domestic hot water.

They are particularly well suited to highly insulated homes with a small heating and domestic hot water demand.
The PKOM 4 which won a Build It 'Best Sustainable Heating Solution' award in 2018, has TWO heat pumps, one 1.3kw heat pump to provide space heating and COOLING and one dedicated to heating 212 litre of water in it's integral water cylinder.

The Combi 185's integrated air source heat pump prioritises the production of domestic hot water and will provide space heating when the 185 litre cylinder has been fully charged. The heat pump is able to produce about 380 litres of hot water every day.

In well insulated homes, some of our clients have found that there is no need for additional heating except a heated towel rail in the bathrooms and in the winter months, a wood-burning stove.

Both units have very compact footprints with the PKOM 4 measuring 741 mm x 734 mm and the Combi 185 at 600 mm x 700 mm (the space previously occupied by a hot water cylinder) and has a low servicing requirement.

The heat recovery matrix is 95% efficient and the hot water cylinder can be connected to a second heat source such as solar panels. A pollen filter is fitted as standard on the supply air to the house.          
Both units are suitable for smaller apartments/townhouses where lower ventilation rates are required.
Typically these systems are suitable for up to four-person occupancy.
