What is Heat Recovery Ventilation and How Does it Work?
Heat Recovery Ventilation (also known as HRV, or mechanical MHVR) is an energy recovery system. Warm, moist air is extracted from the property & replaced with fresh air. Heat energy from the property is recovered & transferred to fresh incoming air via a heat exchanger. Saving energy & money.
Why Do We Need It?
HRV systems provide a property with fresh air, while saving much of the energy usually wasted with traditional extractor fans. They protect the building fabric by reducing condensation, they promote energy efficiency, & improve the internal environment.
As new buildings are made intentionally more airtight they require a ventilation system to assist fresh air ventilation. Trickle vents or opening a window provide fresh air, but heat will be lost in the winter or gained in the summer.
The Best System on the Market
Performing to UK standards, all Ventilation Megastore products are tested so you can trust that you’re buying the best ventilation system on the market.
Ultra Compact and Highly Effective
Our unit is specially designed for use in small properties up to 102m² on normal speed. The unit is compact, easy to install, & provides a low-cost solution.
What is Frost Protection?
Preheat activates when the incoming air is more than 2 degrees cooler than the internal air temperature.
What is Summer Bypass?
Auto-Bypass operates when the incoming air temperature reaches 20 degrees. When this happens, exhaust air is extracted and no heat recovery takes place.

HRVU are easy to install, planning is helpful. Choose the right size of HRV, for your property & room layout as the output for individual rooms will be affected by resistance losses from the type, length, & complexity of ducting.
We recommend that you select a unit that covers your ventilation needs on the normal power setting, providing the opportunity to boost the fan speed to accommodate changes in internal conditions.
Ventilation Megastore offers a range of ducting options & can advise on best practice.
If any regulation compliance is required (e.g. new build properties), it is the installers responsibility to ensure suitable system performance.
Ventilation & Conservation of Fuel and Power are covered by Part F & Part L respectively of Schedule 1 to The Building Regulations 2010
