Today’s buildings are highly insulated and air-tight and with this high level of insulation and air-tightness comes new problems. You still need ventilation in the property. You can either drill a series of 100mm holes in each room to ventilate the building with outdoor air. With this method, the air can be cold, hot, stale, smelly, pollen filled, humid. Sometimes there lots of air coming in through these, say on windy days. Other calm days, your home is not being ventilated at all. The other option is to use controlled mechanical ventilation or HRV." } },{ "@type": "Question", "name": "Will a HRV system heat my home?", "acceptedAnswer": { "@type": "Answer", "text": "Not directly, though it will prevent your home from cooling due to air infiltration. This reduced fuel consumption along with many other benefits." } },{ "@type": "Question", "name": "What are the benefits of HRV?", "acceptedAnswer": { "@type": "Answer", "text": "There are many benefits, though here are the main ones 1. Controlled ventilation. Air flows are fixed for all rooms. You always get the correct level of ventilation required for the particular room. 2. Humidity control. High humidity in homes caused lots of issues. It leads to spore growth, which is bad for anyone suffering from asthma or any other respiratory problem. 3. Mould growth. When spores gather is extremely high levels, they can show in the form of dark stains on ceilings or in the corners of rooms generally. 4. Odour control. Homes sometimes need to be ventilated to remove stale smells. 5. Clearing your bathroom & kitchen. Our new Kinetic unit comes with a built in humidity stat as standard. When you have a shower or cook, humidity levels in the house naturally rise. The unit will detect this and will automatically speed up the fans to remove this humidity. When normal humidity levels are returned, the fans drop back to normal levels." } },{ "@type": "Question", "name": "Is it suitable for oil / pellet / heat pump / solar / gas heating system?", "acceptedAnswer": { "@type": "Answer", "text": "Yes.

This outgoing stale air is sent over a heat exchanger before discharging it to outside. This causes the heat exchanger to rise in temperature to 20°c. The incoming fresh air at 5°c is sent over the other side of the heat exchanger, without mixing the two air streams, and it causes the incoming fresh air to rise to 19°c. This is then blown throughout the house. Without the HRV system, your house would be constantly filled with 5°c air from outside. This then needs to be heated up by the radiators and causes reduced comfort levels." } },{ "@type": "Question", "name": "Where is the fan unit located?", "acceptedAnswer": { "@type": "Answer", "text": "Generally, though not always, it is placed in the attic.

We only use rigid ducting. We use small amounts of flexi duct in strategic spots like final connections to grilles and connections to the fan unit.

An overview of Heat Recovery Ventilation Systems

The Sentinel Kinetic from Vent-axia is the next generation of whole house heat recovery ventilation systems. It will remove your home’s polluted air with ease and provide a constant supply of clean filtered air, allowing you and your family to live in an ideal indoor environment.

Sized correctly, it will gently ventilate the property at a rate of about half an air change per hour, removing moist air and unpleasant smells from the kitchen, bathrooms and toilets and extracting it to the outside. These systems are great in home with allergy or asthma sufferers.

Why should you install a heat recovery ventilation system onto your new home?

If you insulate your building to high standards, install good quality double glazing and low heat loss glass, make the building airtight and do everything possible to help reduce the cost of heating your home; don’t you think it’s crazy to drill 2 x 6″ holes in the wall of each room in order to provide ventilation? Depending on the wind direction, you may be losing excessive heat or not ventilating your home at all. By installing heat recovery ventilation systems, you can block up those 6″ holes and lets fans gently and constantly ventilate the house, while extracting any usefully heat from the exhaust air from kitchens and bathrooms.

Where most people notice the benefits of the heat recovery ventilation system is after a shower is taken as our unit will automatically boost the extract airflow to help clear the bathroom faster. Also, it’s great for removing odours after cooking or after there has been high occupancy in the house or people have been smoking. In the mornings some bedrooms can smell stale and you need to open the window to ventilate the room. With the Heat Recovery Ventilation (HRV) system installed, bedrooms are fresh in the morning and the house doesn’t smell after you have a party because when you were sleeping, the system has been working hard to remove all the stale smells and replace the air with fresh, filtered and heated outdoor air.

Fresh filtered air is drawn into living spaces such as bedrooms and living rooms, providing continuous ventilation even when the house is sealed up for the day. By keeping humidity levels low and introducing warmed fresh filtered air to replace contaminated air, the quality of the internal environment is significantly improved. You can actually feel the freshness in the air within the house.

Continuous whole house ventilation can help reduce relative humidity to below 70% RH, which inhibits the ideal living and breeding conditions of the house dust mite.

The Kinetic heat recovery ventilation unit can be used with a wide range of Vent-Axia controllers and sensors. Ranging from remote controllers to wired remote sensor Air Minder Plus can control your indoor air quality letting your home breathe.
