Demand Control Ventilation, Armagh

Demand Control Ventilation, Armagh

Demand Control Ventilation, Armagh, Northern Ireland. The client decided to build a new two storey 300 m², 6 bedroom low energy home which would take advantage of Low Energy Technology. The basis of this low energy house design was 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. The client was also keen to ensure that the home was well ventilated, and that humidity was controlled.

After consultation with the client, it was decided to install Demand Control ventilation to ensure a comfortable, humidity free environment in the home. Solar hot water panels were installed to provide 60-70% of the domestic hot water requirements and reduce hot water bills. This also ensured that the client received a £320 installation Grant via the Northern Ireland Renewable Heat Premium Payment (RHPP), and will also ensure that the client receives an annual payment via the Renewable Heat Incentive (RHI). A a Grant Vortex oil-fired condensing boiler was installed, resulting in lower heating and hot water running costs. While an underfloor heating system was also installed to distribute and control the heat throughout the home.


 

Technologies Used Demand Control Ventilation, Armagh

 

Solar Hot Water

Solar Thermal Panel Installation Armagh

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

 

Grant Vortex oil-fired condensing boiler

Domestic Plumbing Installation, Armagh

Condensing boilers differ from traditional boilers in that they are designed to capture heat normally lost through the flue system during the combustion process. Unlike traditional oil-fired boilers the Grant Vortex condensing boiler has a built-in stainless steel heat exchanger incorporating Grant’s unique turbulator baffle system, which cools the gases to a point where the latent heat, normally lost to the atmosphere through the flue, can be usefully extracted. The additional energy recovered enables the boiler to operate continuously at much higher efficiency levels, resulting in lower heating and hot water running costs.

 

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.

 

Underfloor Heating

Underfloor heating Installation, Armagh

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.

 


 

Financial Information Demand Control Ventilation, Armagh

 

Fuel Savings

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.

Solar hot water panels provide Savings of up to 50 – 70% annually on the heating cost for your hot water and/or heating. Once you have the panel installed that amount of energy is free for you. The main percentage of your water heating cost is done away through the use of the solar panel. Over time, your savings will increase as the price of oil / gas / electricity and other fossil fuels will increase in the future.

Additional Benefits

As the building regulations demand more energy efficiency in houses, low energy technologies become more important. A low energy house will provide thermal comfort, healthy living, lower heating costs and a high degree of user satisfaction.

Grants and Incentives


 

Renewable Heat Premium Payment (RHPP),

Acorn Renewables Ltd is accredited under the UK Microgeneration Certification Scheme (MCS), and many of our domestic renewable heating products such as the Kingspan 30 Thermomax HP200 evacuated tubes s are also MCS accredited. his accreditation means that solar Thermal (Solar Hot water) panel installations in Northern Ireland, via Acorn Renewables Ltd qualify for the current Northern Ireland Renewable Heat Premium Payment (RHPP), of £320.00 per installation.

Renewable Heat Incentive (RHI)

Plus you can also earn money from your solar hot water system each year with the Renewable Heat Incentive (RHI)
