The most reliable and low energy technique of curing & ensuring safety against condensation, dampness and air quality in the home. Positive Input Ventilation, also known as PIV.
This intelligent home ventilation system is set up in over 1 million homes in the UK and it is the most preferred solution for home ventilation.

How Positive Input Ventilation Works

There are various types of PIV. The Drimaster-Eco range is Dorset Electrical Solutions's market-leading product created for 2 and 3 storey homes with loft. The Flatmaster is developed for flats, apartments and basements. These easy to install & maintain ranges are also economical & cost effective, making them the perfect solution for both brand-new developments and retrofit applications.

Fresh, filtered air is drawn through the near silent unit situated in the loft area of the home. Clean air is then pushed through a diffuser situated on the landing or hallway and dispersed through the home. This positive pressure pushes the humid and stale air out of your home through trickle vents and any gaps in and around your home.


Say Good-Bye to condensation, mould growth and damp and say hello to a healthy home and air quality. The best part about Drimaster-Eco and Flatmaster PIV ranges is that they are quick, low cost, and very easy to set up, making them an optimal remedy for both new constructions as well as retrofit applications.

Why Drimaster-Eco System

Boost your indoor air quality (IAQ) and say goodbye to your condensation and dampness problems with Dorset’s Drimaster-Eco Positive Input Ventilation (PIV) system. We have made a detailed video that will help you decide whether PIV is the right solution for your home. We can supply and install your new PIV system with minimal fuss and at a great price.

Drimaster-Eco PIV system is installed in the loft area where it pulls fresh air with the G4 grade filters, and pushes it to the ceiling level right into the home. In retrofit homes, whole-home ventilation is generally done using the Positive Pressurisation technique as it is a well known and trusted treatment for condensation and dampness.

A consistent flow of fresh and filtered air is circulated into the home which decreases moisture level and prevents dripping windows and black mold patches from developing. It is great for asthma patients and allergy-sufferers as it produces a dry, allergen-free setting suitable for them. Hay fever sufferers also benefit as the G4 grade filters are fine enough to prevent pollen from going into the house.

The controls for the fan are situated within the ceiling diffuser in the Dorset Drimaster Eco warm model which makes it possible for the settings to be changed without going into the loft. A 400w low-energy heater ensures cold air doesn't reduce the temperature level in your home during the winter. The Drimaster Eco includes useful wireless controls and sensing units which respond to transforming moisture and CO2 levels to make sure that only top quality air enters the home while keeping the energy use minimal.
