Below we answer some of the most frequently asked questions on Drimaster PIV units.

1. Will a Drimaster work in a Bungalow?

A Drimaster will work effectively in both Bungalows and 2 storey properties that have a loft area where it can be located. For the Drimaster to work effectively in either type of property there are some important considerations that need to be taken into account. Primarily the loft area should have sufficient ventilation to provide a supply of Fresh air to ensure the Drimaster operates effectively. This is usually achieved through natural leakage into the loft.  It is also important that if you have any extract fans on the ceilings of your Bathrooms then they must be ducted to the outside atmosphere. Location of the ceiling diffuser is also important. It should be located with a slight bias towards the area where the main Condensation and mould is occurring.

2. If I have a Drimaster installed, will I also need Extractor fans in my Bathrooms or Ensuite?

A Drimaster can provide sufficient ventilation in smaller properties where there is no Extract fan in the Bathrooms or En Suite areas. Particularly in homes where there are only one or 2 occupants and moisture production may be relatively low.

However, it is always good practice to have a correctly installed Extractor fan in your Bathroom or En Suite to ensure any moisture created during showering is effectively exhausted out of the property. Basically, the less moisture in your home then the more effective a Drimaster will be in solving your Condensation and Mould problems

3. What size of a property will a Drimaster cope with?

One Drimaster is usually sufficient for a property up to about 1800 sq Feet. The unit has 6 speeds and the size of the house is one of the determining factors which will dictate the speed of the unit.

The speed can be set relatively easy by pressing the up or down button on the ceiling diffuser if it is a HC model or on the back of the Drimaster if it is an LC Model. Please note that there are other factors that will determine the speed at which you will set the Drimaster .

These include the number of people who live in the house and also if you have effective well installed extract fans in your bathrooms and En Suite areas.

4. How long is the warranty on the Drimaster units?

The warranty on a Drimaster is 5 years if you purchase a Loft Control Model or 7 years if you purchase a Hall Control Model. The first year is Parts and Labour and the remaining years are Parts only. The first year Labour warranty has some Geographical restrictions.

5. What Maintenance is required on a Drimaster?

The only maintenance required on a Drimaster unit is to change the Filter every 5 years. The Drimaster Eco will flash a ‘C’ on the display screen when the filter needs changed.

6. What is the Wattage of a Drimaster Heater

Unlike many of its rivals the Drimaster Heater is 400 watts rather than the 500 watt Heaters that other Competitor PIV units have. Despite it having less wattage it is just as effective as the Heater is located on the back of the ceiling diffuser.

This means it works at the very point the air enters into the property through the ceiling diffuser and there is minimal if any loss of heat before it enters your home.

Whereas with other Manufacturers the heater is located on the fan unit and there may be some heat loss through the non insulated duct before it gets to the ceiling diffuser. This means the 400 watt heater will deliver the same amount of heat as the 500 watt heater with up to 20% less cost.

7. What is the difference between the Drimaster Eco Heat HCS and the Drimaster Eco Heat HC?

The main difference between these 2 units is that the Eco Heat HCS cannot be linked to any external sensors for remote operation where as the Eco Heat HC can be linked to several types of remote sensors that will allow the fan speed and heater on/off function to be adjusted remotely depending on user requirements.

For example the Eco Heat HC can be linked to a remote Humidistat that will increase the speed of the Drimaster when the humidity in the property rises above a user set Humidity level. Apart from the ability of the Eco Heat HC to link to sensors it is the same in every other way to the Eco Heat HCS.

8. Is it better to purchase a Drimaster with a Heater?

A Drimaster does not need to have a heater to work effectively. A Drimaster LC or HC(Non heated Models) will solve the Condensation and Mould issues in your home just as effectively without a Heater as a Drimaster with a Heater.

The Heater is primarily for comfort during the colder winter months when the air from the loft area can be cooler. If you do purchase a Drimaster that has a heater then the 400 watt heater works automatically to take the chill out of the air and can be set to kick in at any temperature between 5 and 15 degrees C.

9. Will a Drimaster work in a loft that has spray foam insulation on the underside of the Rafters?

In order for the Drimaster to work effectively there must be a supply of fresh air entering into the loft from the outside atmosphere. This is usually achieved through natural leakage from between tiles and felt or Tile or Soffit vents.

If you have your Loft area Spray foamed then it is unlikely that there will be sufficient air leakage for the Drimaster to work effectively. Therefore, you will have to add some additional means of ventilation into your loft if you want the Drimaster to work as effectively as it can. This additional ventilation can be in the form of Tile vents, Soffit vents or Gable vents.

10. I have an older type Drimaster. Can I purchase a heater to add to it?

In the past you were able to purchase a Drimaster Eco Heater to add to the older Green Drimaster units. These Heaters were 500 watt and could be retrofitted to the old Green units. However, they are no longer produced by the Manufacturer and have been superseded with the Drimaster Eco Heat HCS and the Drimaster Eco Heat HC.

Both these units come with a 400 watt Heater that comes as part of a module. If you want a Drimaster with a Heater then you must purchase one of these 2 units. You cannot add a heater to any of the other Drimaster Eco range.

11. Can I still open windows when I have a Drimaster installed?

Drimasters work on the basis that they build up pressure in the property and displace the Moisture laden air with fresh filtered air. In order for the Drimaster to get this fresh filtered air to every part of the house where Condensation and Mould may occur you need to ensure that windows are not open fully most of the time.

If this is the case then the windows will act as a large leakage point and the airflow from the Drimaster will follow the path of least resistance and make its way out of your home before getting to the areas where it is most needed.
