Demand Control Ventilation Install, Castleknock


Demand Control Ventilation Install, Castleknock, Dublin, Ireland. The client decided to build 4 new homes , ensuring high insulations and energy efficient appliances throughout. The client wanted to install a modern designed heating system throughout the homes which would ensure that the home-owner benefited from renewable energy technology, and future proof their homes against future fossil fuel costs. The client wanted to ensure that the new homes were highly energy efficient and that the central heating and domestic hot water costs would be low. The client also wanted to ensure that the homes were well ventilated, and that humidity was controlled.

After consultation with the client and the new home owners it was decided to install Demand Control ventilation to ensure a comfortable, humidity free environment in the home. An air source heat pump system seemed the ideal method to provide the heating, and this would be combined with an underfloor heating system to distribute and control the heat throughout the home. Solar hot water panels were also installed to provide the client with 60-70% of their domestic hot water requirements and reduce hot water bills. Some house also installed a Worchester gas condensing boiler to remove the need for a solar hot water cycliner in the loft, and to increase energy efficiency.


Demand Control Ventilation Install, Castleknock Technologies Used

Low Energy House – Low Energy Technology. The basis of low energy house design is to take advantage of as much low energy technology as possible in order to reduce the need for traditional building technology which is inefficient or consumes a lot of fossil fuel energy in use.

Ozeo Extractor ventilation system

Ventilation Installation, Armagh

Low Energy Whole House Mechanical Extract Ventilation Unit, or Centralised MEV Mechanical System, provides an energy efficient and cost effective alternative to installing numerous extract fans. The OZEOs are designed to work in conjunction with intelligent, self-adjusting humidity valves to provide a complete demand controlled ventilation solution. The Ø125mm valves will automatically respond to conditions within specific rooms, such as the kitchen or bathroom, and operate accordingly to meet the ventilation requirement. The Ozeo Extractor ventilation system will meet the requirements of Part F of the Building Regulations. The Ozeo Extractor ventilation system will also provide all year round, good indoor air quality using the lowest energy consumption.


Solar Hot Water

Solar Panels Castleknock

In a solar thermal system, the panels harness heat from the sun, which is used to heat the water stored in a solar compatible hot water cylinder. The boiler is linked to the system and automatically starts up if the water in the cylinder falls below the required temperature, ensuring you have all the hot water you need all year round. Effective even on cloudy days and during shorter winter daylight hours, a solar thermal system will typically meet around 60%* of your home’s hot water needs, which could mean considerable savings on your energy bills as well as dramatically reduced carbon emissions


15kW Worchester-Bosch Internal Condensing Gas Boiler & Flue

Renewable Energy Castleknock

The A-rated Greenstar Ri regular boilers are the smallest of the Worchester range of gas condensing boilers, and can be installed within a standard kitchen cabinet. Condensing technology’ has been incorporated into boilers. which enables some of the heat that would otherwise escape from a boiler to be captured and re-used. System boilers require a cylinder for storing hot water, however the major heating and hot water system components are built into the boiler itself, making it quicker and easier to install. In addition, there is no need for a tank in the loft, so it can be an option in a home with little or no loft space . These boilers are also compatible with solar water heating systems, which deliver environmental benefits as well as lower energy bills


12kW Air Source Heat Pump

An air source heat pump (ASHP) is a low-carbon and convenient alternative to a traditional oil boiler or solid fuel heating system. An air source heat pump (ASHP)extracts heat from the outside air – just like a fridge removes heat from inside itself. This heat is concentrated to a higher temperature by the heat pump and then delivered to your heating system, including your hot water tank, radiators or under-floor heating. Air source heat pumps future proof new build homes and property from the unpredictability of global fossil fuel supply. With this in mind the client installed a high efficiency Dimplex air source heat pump, to future proof their home, whilst reducing CO2 emissions and keeping heating bills to a minimum. When combined wih the Solar Thermal Hot Water system, the home-owner also benefited from even greater energy savings


Underfloor Heating

Underfloor Heating Castleknock

Underfloor heating systems work by distributing lower temperature warm water via a pipe network, hidden beneath the finished floor. The heat is then controlled via room thermostats to keep the correct room temperature in each room (zone) of the house. Thus underfloor heating can provide home heating solutions with high energy efficiency and low running costs, and is ideal for home-owners across Ireland are seeking to reduce their carbon footprint, and avoid the rising gas and electric prices. Underfloor heating is ideal for installation in new build, and can is most effective when installed with renewable energy sources such as heat pumps and solar panels. –

Fuel Savings

The A-rated Greenstar condensing boilers are more than 90% efficient, so over 90p of every £1 you spend on fuel for your boiler is used for your heating and hot water. On top of this, intelligent controls can also make a difference by enabling much smarter, more cost-effective management of your heating and hot water system.

Underfloor heating is Significantly less expensive to run than a conventional, radiator-based system. It has been proven that an energy saving of 15-40% can be achieved with underfloor heating.
