Energywise Ireland are leading suppliers of heat recovery ventilation systems. We design, supply and install these systems throughout Ireland.
Heat recovery ventilation systems remove odour and humid air from kitchens and bathrooms. The same volume of clean, preheated air is supplied to bedrooms and living rooms. Since the energy of the extracted air is transferred to the fresh, cool outdoor air, 95% of the heat is retained – and that means maximising energy for minimum cost. The filtered and, consequently, cleaner air increases the comfort for you and your family.
Our high-quality ventilation systems ensure efficient, clever ventilation. You are embraced by fresh air, at home and in the office. That way you increase the comfort, reduce the influence of fine dust, moisture and other harmful substances, you have more control of your energy bill and you help to reduce CO2 emissions.
Are you building a new home that’s airtight with lots of insulation? Then talk to the energywise team, you will need a mechanical heat recovery ventilation system to ensure clean, fresh, warm air circulation.
Have you recently insulated and sealed your existing house and you now have condensation or mould problems? Then talk to the energywise team, there is build-up of moisture within the building now that now can’t escape, a HRV system can often be retrofitted to existing houses and will help to control or eliminate such condensation and mould problems.
1. Brink Heat recovery ventilation systems are designed to recover up to 95% of the heat normally lost through open windows, vents and other breakout points.
2. Fresh air is continuously drawn into the home via a low energy heat recovery ventilation unit, usually located in the attic or utility area.
3. Once passed through the heat exchanger within the HRV ventilation system, the warm, clean, fresh, filtered air is distributed around the home through a series of ducts. Since the energy of the extracted air is transferred to the fresh, cool outdoor air, 95% of the heat is retained. That means no waste of energy.
4. Air from wet rooms e.g. bathrooms, kitchens, etc. is continuously extracted and filtered back through the heat recovery ventilation unit. The heat from the extracted air is transferred to the fresh incoming air. HRV can also dissipate warm air from your home in Summer, bringing in cool, fresh air from outside.
5. With the auto summer by-pass, the HRV unit automatically controls whether to reclaim heat energy (or not) based on temperature. This ensures that your house does not get over-heated while still remaining air-fresh.
Effective ventilation contributes to living comfort and health. Users are putting ever higher demands upon good ventilation possibilities in all seasons. In addition, government requirements with regard to energy efficiency and installation noise are getting stricter all the time. Brink Climate Systems responds to that with the introduction of the Renovent Excellent Series.
These heat recovery ventilation appliances are not only fully geared for present-day ventilation requirements, but also for those of the future.
The existing Renovent Excellent 400 has now been joined by the Renovent Excellent 300 and the Renovent Excellent 180, resulting in a Renovent Excellent series. The Renovent Excellent 400, 300 and 180 are distinguished by their capacities (400, 300 and 180 m3/h at 150 Pa respectively).
Silent: A special property of the latest Excellent versions is that their fans run slower, making them a lot quieter than their predecessors. The heat exchanger and the lower internal resistance also contribute to the silent operation of the Renovent Excellent.
Lower auxiliary energy consumption: Additional advantage of the noise reduction measures is that these also reduce the auxiliary energy consumption. With the Renovent Excellent series, Brink Climate Systems succeeded in introducing appliances that now already comply with the future European energy requirement of 900 J/m3. The auxiliary energy consumption has been reduced by roughly 40%. Today you already benefit from a further EPB reduction.
Types: The appliances of the Renovent Excellent series are available in a left-handed and right-handed version with 4 connections at the top. The Renovent 300 is also available with 2 top and 2 bottom connections and in a version with 3 connections at the top and 1 at the bottom. In addition to the comprehensive standard version, the Renovent Excellent is also available as ‘Plus’ version'. The latter has extra options for connecting CO2 sensors. These sensors ensure that a certain space - for instance with many people - is temporarily ventilated more intensely than other spaces.
No is the short answer. A heat recovery ventilation system is purely to manage the ventilation of the building, providing fresh air and extracting stale air and steam. A heat recovery ventilation system will reduce the heat demand of the house regardless of the type of heating system as it reclaims a proportion of the heat that would have been lost in the air changes of the house.
A properly specified and installed heat recovery ventilation system should be barely audible if at all. However whenever the unit is on boost mode the ventilation rate is increased so more air is moving through the vents and the sound may become noticeable but this is generally only when someone is having a shower.
Some manufacturers in the past have toyed with this but have since discontinued with the principal. A cooker hood typically moves a lot of air, often more than the whole house ventilation rate would be, so to add this extra demand onto the heat recovery ventilation system would mean compromising the extract rate from the cooker hood or increasing the ventilation rate for the whole house by a lot. It is generally recommended to us a recirculating cooker hood with activated charcoal filter for dealing with the steam and odours from the cooker. With this the heat that the cooker produces is not just pumped outside as is done with an extractor hood. The heat recovery ventilation system would typically have an extract vent in the kitchen located between the cooker and the sink to extract whatever steam that escapes the cooker hood.
No. The heat recovery ventilation ducts (pipes) are all hidden above the ceiling level of the rooms. The only thing that is seen is the small white circular ceiling vent of which there would usually be one in each room.
The heat recovery ventilation unit itself is usually located either in the attic space or in a plant room where other services for the building would be located.
Not usually. There is usually a supply vent in the likes of bedrooms, living areas, sitting rooms etc. The extract vents would be in bathrooms, WCs, utility, en-suites etc. This arrangement allows for the fresh air to be fed into the rooms where you spend most of your time. With the extract in other rooms it causes the air to flow from supply rooms in the direction of extract rooms ensuring a cross ventilation of the whole building.
No. The heat recovery ventilation manages all the general ventilation as well as the extract ventilation for the building so extra wall vents are not required. The only exception is where there is a fire place or stove in a room which must have its own dedicated air supply. This is usually done by installing a vent pipe from outside directly to the location of the stove or fireplace so as to not cause a draught in the room.
The cost to run a heat recovery ventilation system per year depends on the size of the house. The larger the house the more air needs to be moved and so the fans have to work harder. A house of 250m2 would cost in the region of €40 to €60 per year to run. The same system would reclaim an energy value roughly equivalent to 200 litres worth of oil per year.
No. The heat recovery ventilation system manages the extraction of the steam from the bathroom and reclaims some of this heat to contribute to the heating of the building.
This depends on the air quality in the area and the amount of activity within the building. In some installations it is only necessary to vacuum the filters about once a year and change them every few years while in other installations the filters may need to be changed once a year.
