What is heat recovery air handling unit?

Heat recovery units are supply and extract systems delivering filtered fresh air into a building whilst extracting stale, stagnant air from the interior. Heat recovery units come with Ecosmart control as standard which interfaces with the fan and heating system for simple, localised fan control.

How does a heat recovery fan work?

Heat recovery ventilation works independently of your normal heating system. These flow past each other without mixing physically but the heat is drawn from the stale air to the cold air, which is then fed back down into the pipes and into the rooms. The stale air, minus its heat, is then expelled into the atmosphere.

What does a Nuaire do?

Nuaire invents Positive Input Ventilation Fresh air is drawn through the loft by the PIV unit, filtered and passes via the ceiling diffuser, creating a positive pressure within the home forcing air pollutants out through the natural leakage gaps found in every home.

Are heat recovery systems worth it?

Of course, the main benefit of heat recovery is that there’s less wasted heat, which means less money wasted on fuel costs. If you live in a newer home that’s well-insulated and sealed up tight, then the extra fresh air you’ll get from a heat recovery ventilator will be well worth the cost.

Are heat recovery systems noisy?

However, it is worth remembering that no matter how high the quality of a heat recovery unit, it will generate noise, or “humming”, in the air duct and the housing. The noise levels which we manufacturers have to indicate is the acoustic power level of the device housing.

Do heat recovery systems cool?

Can an MVHR system help to cool your home in summer? Yes, a Mechanical Ventilation with Heat Recovery system (MVHR) can help to cool your home in summer, and it does it in a way that is quiet and automatic, using only the energy equivalent of two LED lightbulbs.

What is the best cooling system for a house?

Do I need a heat recovery system?

This can lead to unpleasant smells and a build up on toxic gases and even lead to health problems such as asthma and other respiratory problems. If you want to reduce your heating costs, have a constant supply of fresh, filtered air in your home, no mould, mildew or condensation then a heat recovery system is for you.

Do PIV units work?

Do PIV units work? The short answer is yes. PIV units work, and their effect is transformational. We’ve installed PIV units in homes where the owners thought they would have to leave because of relentless damp problems.

How much does a PIV unit cost to run?

On average a PIV unit will consume 5 watts of power which will cost just 1p a day to run. As a result, PIV systems have long been considered one of the most affordable ways to provide whole home ventilation.

How much does a heat recovery ventilator cost?

High efficiency models can reduce heating energy consumption by up to 18%. Generally, medium-sized (70-120cfm) recovery ventilators cost between $600 and $1100, not including installation. Costs vary according to quality, capacity, controls, efficiency, and type. ERVs can cost $150 to $200 more than a comparable HRV.

Why do you need a Nuaire heat recovery system?

What are the benefits of a Nuaire MVHR system?

Nuaire’s MVHR systems provide optimised, balanced ventilation with heat recovery with 95% efficiency. Our systems will quietly and efficiently provide the home fresh, filtered air all year round, improving the indoor air quality and reducing dust and allergen levels.

When did Nuaire invent Positive Input Ventilation?

Nuaire invents Positive Input Ventilation It was in 1972 that Nuaire invented a cure for condensation dampness in residential properties and its associated problems. Installed in over a million homes Positive Input Ventilation (PIV) – is the UK’s most popular method of low-energy whole home ventilation.

How does the run around coil in a Nuaire work?

In this instance the run-around coil uses water in the exhaust airstream coil to absorb exhaust heat energy which is then pumped to a coil positioned in the supply airstream where heat is transferred. When needed, a commercial heat recovery system can be adapted to incorporate cooling, additional filtration and sophisticated control packages.
