Heat Recovery Ventilation systems primary function is to ventilate airtight homes and in doing so recovers heat that would otherwise be lost to extract ventilation

Payback should be measured in the health benefits to the residents as well as return on investment which can be as little as 3 years depending on how building air tightness.

Yes, Ireland’s climate is with mild, humid and changeable with abundant rainfall and a lack of temperature extremes

In winter severe cold weather is uncommon,

However temperatures are lower with wind driven rain & air moisture between 70 to 100%.

The wind chill factor and damp air make it feel much colder

Homes have become better insulated and more airtight to reduce heat loss and drafts But condensation issues have got worse as homes are under ventilated

Why Are Irish Houses so Damp & Cold

Recovers heat that would otherwise be lost to extract ventilation

There is no need to install ‘hole in the wall’ trickle vents, window vents and extract fans (Bathrooms, En suites Utility & Kitchen) that allow  cold damp drafts in and heat to escape

With Heat Recovery Ventilation in winter there is no need to open windows or turn on extract fans to remove bad smells, that damp felling is gone as humidity is automatically reduced and the summer bypass helps to cool on hot summer nights.

Find out where heat is escaping with a Heat Loss Home Inspection

Yes Heat Recovery Ventilation systems can be fitted in older homes but we would advise that insulation and especially air tightness is upgraded i.e. during whole house remodelling.

We can perform an airtightness test to see if Heat Recovery Ventilation is suitable for your home in order to achieve the full benefits of Heat Recovery Ventilation, otherwise you will not see a return on your investment

Heat Recovery Ventilation will work with heat pumps and other heating systems

Their primary function is to ventilate airtight homes significantly reduce demand on the homes heating system and balance heat distribution throughout the home.

Homes built to the latest the nZEB  –  nearly Zero Energy Buildings standard  & Irish Building Regulations 2019 part L & F with excellent attention to detail on Insulation and airtightness, Heat pumps are hardly calling for heat in the depts of winter and not at all at other times of the year

Heat pumps work like Fridges but instead of cooling they are used to heat buildings while Heat Recovery Ventilation systems primary function is to ventilate airtight homes and in doing so recovers heat that would otherwise be lost to extract ventilation.

No Heat Recovery Ventilation systems primary function is to ventilate airtight homes and in doing so recovers heat that would otherwise be lost to extract ventilation

By recovering heat from extract air they significantly reduce demand on the homes heating system and balance heat distribution throughout the home.

We have experienced new homes with excellent attention to detail on Insulation and airtightness that heat pumps are hardly calling for heat in the depts. of winter and not at all at other times of the year as heat from house hold appliances, body heat and solar gain through triple glazed windows is enough to maintain thermal heating comfort levels

Reduce your heating costs by up to 70%.      

Struggling to get to sleep on hot summer nights during a heat wave?

Yes the Heat Recovery Ventilation systems contributes to cooling homes during the summer this works by a summer bypass

Overheating due to global warming, increased levels of insulation, airtightness and solar gain through windows & glazing patio doors is becoming more frequent                                    

Unlike air conditioning units which cools air by refrigerant technology recycling it back to the room consuming a lot of electricity.

The Heat Recovery Ventilation system works by bypassing the heat exchanger when the outside temperature is above 14 °C and the inside temperature is above 24 °C.

Such as in the evening & early night when people are going to bed and are struggling to sleep due to the heat but can’t leave the windows open due to security concerns and flying insects.

The advantage of Heat Recovery Ventilation is that windows can be shut at night, cool fresh air is drawn from outside and it is extremely economical to run.

The warm air is flushed out and cool fresh air is drawn from outside.

With “Push of a switch”, purge mode you can boost the unit to 100% purge mode for 2 hours after which the unit returns to normal mode and it runs at 20% during sleeping hours

Cool down house during hot summer nights

Boost switches are located in the kitchen, utility and outside toilets, bathrooms and ensuites.

With a “Push of a switch”, the Boost increases fan speed to the highest setting, increasing airflow on demand, and is ideal when large gatherings in the home require greater ventilation

Boost quickly improves indoor air quality in any room of the home where air suddenly becomes undesirable or contaminated from sources such as large social gatherings, cooking vapours, crowds, smoke and bad odours.

Heat recovery ventilation systems emit very little noise and will certainly not be heard above background noise such as a shower or fridge.

During sleeping hours the unit has is set back to very low speed that reduce noise to less than a quiet whisper.

The European Energy Performance of Buildings Directive requires all new buildings to be nearly Zero Energy Buildings (nZEB) it is a legal requirement under the EU and Irish Law. Click here for more information on nZEB.
