The installation of a PIV unit can greatly increase indoor air quality and prevent many of these issues. The nice thing about the Nuaire Drimaster PIV Unit is that it is easy to maintain. You want to replace the filters every three to five years on average. This number could vary based on your circumstances. For example, if you live near a main road or area with extreme pollen, you might find that they need to be changed more often. In simple terms, positive input ventilation (PIV) is a method of ventilation used to improve the house’s air quality. This device uses a fan to push out moist and stagnant air while replacing it with fresh, filtered and dry air. As a result, ventilation is improved around your home, thus curbing breathing problems and preventing property damage. Currently, over 1 million homes in the UK are fitted with PIV units! Some PIV units come with the option of warming the air as it is blown into the home. Because of this, you benefit from a warmer home as well as a dry one. How does a PIV unit work? You will also need to make sure that Building Regulations Part F is complied with, as the PIV unit does not act as an extract ventilator.

The airtightness of the property does play a part as air will travel the path of least resistance and you don’t want it escaping out the nearest window and having no effect on rooms further away from the diffuser. This heater ensures that the air entering the home is in line with your comfort level. By warming the air at the ceiling level, you save energy. In addition, the Nuaire Drimaster PIV Unit helps to remove indoor pollutants from cleaning and cooking. It also keeps the outdoor pollutant like pollen and traffic fumes where they belong. Drimaster-Eco Positive Input Ventilation (PIV) ventilation systems are the most effective method of curing and preventing condensation dampness. Recommended for planned and reactive ventilation servicing, essentially the concept is to introduce fresh, filtered air into the dwelling at a continuous rate, encouraging movement of air from inside to outside. To achieve this, the unit is mounted in the loft space, drawing air through the filters and inputting it, at ceiling level, into the property. An integrated heater tempers airflow should the temperature in the loft space drop below a set point, ensuring ultimate comfort in the home. A Positive Input Ventilation (PIV) unit is designed to improve indoor air quality by introducing fresh air into your home through a filter, while at the same time, expelling stale air out. PIV units can help control humidity levels and prevent condensation, but they are not specifically designed to reduce humidity levels in the air.PIV systems create fresh and healthy living environments by supplying fresh, filtered air into a property at a continuous rate throughout a property and is our most popular method of whole house ventilation. Energy recovery ventilation systems provide a controlled way of ventilating a home while minimising energy loss. They reduce the costs of heating ventilated air in the winter by transferring heat from the warm inside exhaust air to the fresh (but cold) outside supply air. It’s important to note that this unit doesn’t in itself provide any extraction of water. Instead, this PIV unit works by pumping fresh air into your home. When this happens, the old air is forced out and your condensation levels are lowered.

On the other hand, a dehumidifier is specifically designed to reduce humidity levels in the air by extracting moisture from the air. They can be particularly useful in damp environments, where there is a high risk of mold and mildew growth. In addition to the low power consumption, extremely quiet operation and very low maintenance, these models include a daily run monitor as standard, and automatic heat recovery mode. It is important to note that the Nuaire Drimaster PIV Unit also meets Part F and Part L of Building Regulations meaning it is a low-energy strategy for ventilation. Suitable as a social housing ventilation solution, we have 7 different model types, starting with our basic model below that have been designed for occupant preference and house type. It’s also worth noting that due to the positive pressure nature of a PIV unit, the temperature of the air it circulates will be somewhat affected by the temperature of the air in the loft. Hot air does rise, so this could warm your home somewhat, however, if your loft is under-insulated, in the colder winter months, this could cause colder air to be pushed through your home. PIV units can be combined with heaters, but this may undermine its low energy qualities, and cause running costs to rise significantly. Is Positive Input Ventilation Worth it?
