What makes up your Low Energy Home Heating & Environmental Technology Air Source Heat Pump How it works Even cold air is full of energy and air source heat pumps use the freely available heat in the ambient air to provide efficient heating and hot water at air temperatures as low as -25 °C. Because the source of heat – the air – is abundantly available all around us, air source heat pumps have the advantage of low installation costs and minimal space requirements, making them ideal for new build applications. Suitable for either indoor or outdoor installation, air source heat pumps can be used for heating, cooling and to produce domestic hot water and with the relatively mild winter temperatures in the UK, can achieve seasonal co-efficient of performance comparable with ground source, meaning excellent levels of performance can be achieved throughout the year. Ground Source Heat Pump How it works The earth stores an enormous amount of solar energy from both solar radiation and rainfall, ground source heat pumps extract this freely available energy to provide low cost, low carbon, high efficiency heating and hot water. To extract the energy ground source heat pumps use collectors, filled with a mix of water and antifreeze, buried in the earth, either horizontally or, if available land area is limited, vertically. Although more costly to install than an air source heat pump, with the constant temperatures below the surface of the earth throughout the year, ground source heat pumps deliver high levels of efficiency all year round irrespective of seasonal variations in air temperature. Gas/Oil Condensing Heating System How it works Modern condensing boilers simultaneously generate warmth for heating and for hot-water provision through the combustion of gas or oil. By using the heat that remains in exhaust gas, the energy content of the fuel is used almost in its entirety, making gas-fired condensing technology especially efficient as well as very convenient. These boilers can be wall or floor mounted and an appropriately sized model will be installed depending on the heating requirement of the individual property. Heat Recovery Unit How it works With air tighter new buildings, whole house heat recovery ventilation is the most effective ventilation strategy on the market. Heat recovery continuously extracts humid air from wet areas such as kitchens and bathrooms and using a heat exchanger, transfers the heat to filtered incoming outside air which is redistributed to the living areas and bedrooms. Heat exchangers are up to 93% efficient which significantly help reduce heating bills, plus the effects of condensation are dramatically reduced. 14
Home Technology Rainwater Harvesting Solar Water Heating PV (Photovoltaics) Integrated Technology Rainwater Harvesting works by taking the rain from your roof gutters, filtering out leaves and debris and storing the water in an above ground or underground tank. This water can then be used for non-potable applications such as vehicle washing, irrigation, toilet flushing and washing machines. Solar water heating systems use solar panels, called collectors, fitted to your roof. These collect heat from the sun and use it to warm water which is stored in a hot water cylinder. There are two types of solar water heating panels, they are evacuated tubes (like in the picture above) and flat plate collectors. Flat plates collectors can be fixed on the roof tiles or integrated into the roof. An air source heat pump heater can be used as a back up to heat the water further to reach the temperature set by the cylinders thermostat when the solar water heating system does not reach that temperature. Solar PV panels require only daylight, not necessarily sunlight to operate, and they are therefore capable of generating electricity even on cloudy days. Solar PVs will work equally well in urban or rural locations and can be installed on the roof of most homes that can support the equipment. They can easily be connected to a building’s electricity supply and any unrequired energy can be sold back to the national grid. When in use, Solar PVs do not generate greenhouse gases or cause pollution. Each kilowatt-peak (kWp) of electricity produced can save approximately 455 kilograms of carbon dioxide emissions compared with electricity generated from fossil fuels. The UK Government is currently offering attractive incentives for those creating their own ‘green electricity’ .
