Heat Recovery Ventilation
ITHO Mechanical Ventilation with Heat Recovery (MVHR)
Carroll Renewables and Itho:
Like the Carroll Joinery Group the Itho Group is a long established market leader. Itho has been in operation since 1919, offering energy efficient products for homes and businesses throughout Europe.
Carroll Renewables offers the full range of itho products from PVC ducting and valves to Cooker Hoods and CO2 sensors.
We carry an extensive range of products available ex-stock from any of our outlets nationwide.
Buildings suitable for Itho HRU ECO 4 installation:
- Residential buildings
- New builds
- High and low rise buildings
- Renovations (where improvements to air tightness have been made)
The triangular formation of the synthetic heat exchanger offers maximum surface area for heat to be transferred and this combined with its quiet energy saving DC motor makes for an incredibly efficient system.
Tested on a kitchen plus up to 7 additional wet rooms, the unit can be easily installed into a loft space and is controlled by state-of-the-art 3 speed wireless controllers.
Designed to adapt to any climate, the system is equipped with an integrated, fully automatic summer bypass valve when the exchange of heat is no longer necessary, along with a frost protection device that adjusts the fan speed and combines fresh incoming air with the warmer air surrounding the unit to prevent the system from freezing.
SAP Appendix Q:
SAP is the UK Government's Standard Assessment Procedure for calculating the energy performance of Dwellings. It is used to demonstrate compliance with building regulations within the following areas - Part L (England and Wales), Section 6 (Scotland) and Part F (Northern Ireland), and provides energy ratings for dwellings that can be compared nationally.
The Appendix Q procedures apply specifically to MVHR and MEV systems, both of which are offered through Itho in the form of their HRU ECO 4 RF and CVE ECO 2 systems. Both have been designed to comply with the requirements set within the SAP Q and both have excelled when independently tested by the BRE, setting them up as two of the most versatile and efficient ventilation systems on the market.
