Mitsubishi air to water heat-pump domestic air source heat-pump boiler

Mitsubishi Electric Ecodan advanced air source heat-pump boilers.

Why Ecodan is more efficient than any other form of heating solution.

With conventional boilers, 1kW of input energy provides less than 1kW of output energy or heat. With Ecodan, every 1kW of input energy is converted into an average of 3.6kW of output energy or heat, making it more than three times as efficient as conventional boilers and a natural choice for low cost heating and hot water. The Co-efficient of Performance (COP) of a heat pump is the ratio of the heat delivered, divided by the power consumed. The modern heat pump technology used in Ecodan and given in this example has the seasonal COP rating of 3.6. By 2016, over 720,000 tonnes of CO2 emissions per annum could be saved if all the 200,000 residential properties built

Massive savings

each year installed heat pumps. If a heat pump also replaced 10% of the gas boilers sold each year in existing properties, the potential annual saving would increase to over 2 million tonnes of CO2 by 2016. By transforming the energy found naturally in outdoor air and using that to help provide cost effective heating, we’ve already established the efficiency of Ecodan and the fact that it ‘upgrades’ energy. Take that one step further and consider using Ecodan powered by electricity from a renewable energy source such as wind, biomass, solar or tidal and you could have a heating system that is zero carbon rated. Another advantage with Ecodan is it’s ease of installation and design flexibility. A perfect answer to those wide areas of the UK that are not perhaps on, or likely to be on the National Gas Grid. This negates the need to consider the more costly options of electricity or oil and removes the need to negotiate the enormous expense and disruption of extending the National Gas Grid. Whatever the location, simply install Ecodan and enjoy efficient, effective heating and hot water at a fraction of the alternative cost.

Inverter-driven technology

At the heart of Ecodan is a modern, inverter-driven heat pump compressor which converts free energy from the air and upgrades it to higher temperatures suitable for heating. The inverter control regulates the system so that heat output modulates to match the exact capacity required, meaning the boiler will only consume the exact energy needed at any given time and thus increase efficiency further. The advanced heating technology used in heat pumps make them ideal for use in the UK’s ambient temperatures and hence perfect for the domestic market.

The technology inside the heat pump is similar to any domestic refrigerator, which uses a vapour compression cycle. The main components in the heat pump are the compressor, the expansion valve and two heat exchangers (an evaporator and a condenser).

How it works

Refrigerant in the evaporator is colder than the heat source. This causes the heat to move from the heat source (in this case the outside air) to the refrigerant, which then evaporates.

This vapour moves to the compressor and reaches a higher temperature and pressure.

The hot vapour now enters the condenser and gives off heat as it condenses.

The refrigerant then moves to the expansion valve; drops in temperature and pressure; and then returns to the evaporator.

CO2 emissions reduced by 30%

The Code for Sustainable Homes

There is currently a substantial under supply of housing in the UK. In order to meet the demand for new homes, the housing sector is set to increase its build rate by 23% over the next 20 years. This means that by the year 2050, over a third of the UK’s housing stock will have been built inside of four decades. The Government is therefore focussed on using this growth as the ideal opportunity to cut energy use and water consumption in homes and is introducing legislation and guidelines in support of this.

Introduced in 2006, The Code for Sustainable Homes is part of the growing body of legislation aimed at reducing CO2 emissions. Using a rating system of one to six stars to depict the overall sustainable performance of a house, with one star being above the standard of the current Building Regulations. Code Level 3 CO2 Emission Reductions can be achieved by the deployment of Ecodan advanced heating technology, in conjunction with notional energy saving methods such as improved thermal insulation. As energy used in buildings is responsible for almost 50% of the UK’s carbon burden, the commercial and residential building sectors are under close scrutiny as far as energy efficiency is concerned. That said, more than a quarter of the UK’s CO2 emissions are as a direct result of us heating, lighting and running appliances in our homes. Domestic space and water heating produce over 70% of an average home’s CO2 emissions, therefore reducing these is of paramount importance. It’s no surprise, that in order to reduce CO2 emissions, we need to focus our efforts on seeking new, more effective means of heating homes. Central and local government are using legislation and strict guidelines to ensure that homes are as energy efficient as possible. In the social and private housing sector, designers, builders and installers increasingly need to utilise new and advanced technologies to ensure they meet the new ruling designed to cut CO2 emissions and make better use of energy.

Must be installed by Orion air conditioning to meet Mitsubishi Installation standards.

The Ecodan heat pump is a self contained unit which only requires water and electric connections. Water pipe size is 22mm and electrical feed required is 16 amp / "B" type MCB. The unit must be sighted outdoors either on a wall bracket or floor mounted. These units can be fitted by electricians, plumbers, heating engineers and air conditioning engineers. Furthermore, Ecodan is supplied as a sealed system so it does not have to meet the new F-Gas Regulations. As a result the developer does not have to find specialist refrigerant handlers to install the equipment. Ecodan is straightforward to install.
