Single Room Heat Recovery (SRHR) systems provide localised mechanical ventilation with heat recovery for individual rooms where centralised systems are not practical.
Single Room Heat Recovery Ventilation can be used as an alternative to a centralised Mechanical Ventilation Heat Recovery (MVHR) unit for single wet rooms or remote locations where there is an outside wall, making it an ideal option for refurbishments or where there is a remote room unable to be reached by a c-MEV or other extract unit.
These units can be offered in a variety of ways, with some providing continuous mechanical ventilation with simultaneous heat recovery, and then supplying fresh air back into a single room with the benefit of the recovered heat.
Some units have push-pull controls, extracting for a short burst before switching to the supply of air and vice versa. These units can include humidity sensors, pullcords, usage sensors and wireless controllability depending upon the application, and are known to have low noise levels.
These systems are easy to install and can often be provided with different cell lengths depending upon the thickness of the external wall.
Frequently Asked Questions
A Single Room Heat Recovery Unit (SRHR) is a version of a Mechanical Ventilation Heat Recovery (MVHR) unit designed for a single room or space, providing localised mechanical ventilation and heat recovery from extracted air.
These can be used in conjunction with a regular, centralised MVHR unit if there is a single room in a remote area in a property or if the layout of the property allows. SRHR units can sometimes be ducted, but are often installed through-wall, so would require an external wall for mounting.
Depending upon the nature of the unit, there may be specific stipulations regarding installation requirements, such as the heatSava that, due to airflow directions and the potential of short-circuiting, should not be installed in a corner of a room. SRHR is considered an alternative form of ventilation.
