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? The PIV unit works on the whole house, and so you don’t have to utilise damp busting methods in different rooms

When the loft exceeds temperatures of 23°C, the unit will go into a summer month system standby which saves you energy and time. Nuaire Drimaster Filters New and modern homes are at risk of condensation: poorly heated homes are prone to condensation dampness. In contrast, well-insulated homes with double glazing or insulation can trap moist air inside the house. When it comes to curing damp and condensation, PIV is the most cost-effective whole home system in the market today: that’s why it’s trusted by so many homeowners and landlords across the UK. How energy efficient are Nuaire’s PIV units? 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? 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. Another alternative upgrade on the HC model with the ability to link to a choice of wireless controls and interactive sensors: including the relative humidity (RH) and carbon dioxide sensors which automatically increase the fans speed when the target setting on the sensors are met.The general rule of thumb is that anytime you notice a reduction of quality air in your home, start by replacing the filter. Nuaire Drimaster Installation Further, most new homes are insulated from heat loss using modern materials. As well as preventing heat from escaping, these can also prevent moisture from escaping. Consequently, this leads to a buildup of moisture which precedes issues with condensation and mould. This model’s non-disruptive installation makes it ideal for repairs and maintenance schemes making it a favourite with social house providers. If you want to learn more about how a PIV unit works, we’ve written an article, “ What is a PIV Unit?”

An alternative to the LC model with the advantage of a 7 segment display located in the ceiling diffuser allowing complete control without accessing the loft. Extremely energy efficient – System goes into standby during warmer months when there is no evidence of condensation Choosing between a PIV unit and a dehumidifier depends on your specific needs and the environment you are trying to improve.With this system, you can expect to enjoy a high-quality breathing environment throughout your home. This means you can expect a reduction of allergens that lead to asthma and other respiratory illnesses. In addition, you should see less condensation, mould and odours in your house.
