Titon announced on 13 September 2023 that it has expanded its mechanical heat recovery range with the HRV4 Q Plus Range, a whole-house ventilation unit for residential applications1. The company said the new model keeps the 600mm width of its smaller units while increasing airflow capacity1.
The unit is rated at an airflow of up to 158 l/s (568 m3/h) at 100 Pa, with a Specific Fan Power as low as 0.38 W/l/s and heat recovery of up to 91%1. It measures 600mm wide, 602mm high and 477mm deep, and can be configured for left or right hand installation on site1. Titon states the range has full MODBUS and WiFi connectivity through its aura-t controller and auraSmart app1.
"We are the only supplier to be able to offer a full range in 600mm width"
Titon said its most popular products have been the smaller 600mm wide units, the HRV1.25-1.35 Q Plus and HRV1.6-1.65 Q Plus, and that it now has a range of three units covering low to high airflow requirements1. James Fisher, Titon's Commercial Director, described the range as a game-changer in the ventilation industry, citing its airflow capacity, energy efficiency and smart connectivity1.

Why it matters for households
An MVHR system extracts stale air from kitchens and bathrooms and supplies filtered fresh air to living spaces, transferring heat from the outgoing air to the incoming air so that a home does not lose all its warmth as it ventilates. The heat recovery figure quoted here, up to 91%, is the share of that heat the unit can retain, and the Specific Fan Power figure, down to 0.38 W/l/s, indicates how much electricity the fans use to move each litre of air per second. Both numbers bear on running costs and on how much a home depends on its own ventilation rather than on opening windows, which loses heat.
The 600mm width matters where space is tight, such as a kitchen cupboard or a loft void, because a unit that fits the available slot can be installed without altering the building fabric. Left or right hand configuration on site gives an installer flexibility over where the duct runs connect. The connectivity features allow monitoring and control through a controller and app, which is relevant to households wanting to see how the system is performing rather than setting it and forgetting it. Titon is one of a number of manufacturers in this market; the announcement does not give prices, energy ratings or warranty terms, and none of these have been reported.
