Have you ever stopped to consider what the key contributors to your monthly electricity usage are? You may be surprised that in New Zealand, on average, domestic hot water heating combined with heating your home accounts for a whopping 67%† of the overall energy bill! So if you are trying to find ways to make significant savings on your electricity consumption, domestic hot water heating is an obvious area to target. Up to now the majority of hot water in New Zealand is heated by traditional electric hot water cylinders – but is there another, more energy efficient way to do this? The answer is yes, and it’s called hot water heat pump technology.
4 Hot Water Heat Pumps are Better for the Environment Did you know a traditional electric hot water heater produces up to three times the amount of greenhouse gas compared to a low emission alternative such as a hot water heat pump? Instant gas hot water systems are even greater greenhouse gas contributors, producing a staggering seven times more emissions compared to hot water heat pump technology.*1 This makes water heating one of the largest single sources of greenhouse gas emissions from the average Kiwi home. As such, EECA has identified heat pumps as playing a key role in the ability to significantly reduce costs and greenhouse emissions from energy use. Currently an estimated 67% of New Zealand homes use a traditional electric hot water system in the home.*2 Substituting existing, less efficient technologies with more efficient ones such as a hot water heat pump therefore has the ability to make a significant reduction in overall greenhouse emissions. If you are looking for super energy efficient water heating that is kind to the environment, Mitsubishi Electric Ecodan Hot Water Heat Pumps are the natural choice. *1 Based on electrical and gas emission factor for New Zealand (EECA Genless). *2 B ased on E3 Policy Framework data for New Zealand.
5 1kW Electrical energy input 3.2kW Heat energy output 2.2kW Low temperature renewable heat energy taken from the environment How Efficient is a Hot Water Heat Pump? The efficiency of a heat pump is known as the Coefficient of Performance or COP. This is a ratio of the heat delivered to power consumed. For every 1kW of electrical input energy, Ecodan absorbs freely available heat energy from the outdoor air to provide the home with an average of 3.2kW*3 of heat output. Compared to typical gas and direct electric heating systems that can have higher running costs with inefficient COPs as low as 0.80*4, Ecodan Hot Water Heat Pumps provide a real energy efficient alternative. “Now you can enjoy hot water responsibly all year round!” *3 A s independently tested by BSRIA based upon BSEN14511 Part 3 standard rating conditions. Due to the method of operation, the performance of heat pumps will vary based upon the temperature of the heat source and the requirements of the heat delivered. The BSEN14511 testing relates to the heat pump performance only and not the entire heating system. *4 Based on manufacturer information for gas instant hot water heater (non-condensing).

6 How Does an Ecodan Hot Water Heat Pump System Work? There are three key components to the Ecodan Hot Water Heat Pump System. The Outdoor Unit Just like a heat pump for space heating, the Ecodan outdoor unit uses electricity to absorb freely available heat energy from the surrounding air and then transfers it to your home so it can provide energy efficient hot water heating and heating for underfloor, radiators or fan coils. The Hot Water Cylinder Ecodan provides your home with hot water via a dedicated all-in-one pre-plumbed 200 or 300 litre cylinder that is specifically designed to integrate with the Ecodan outdoor unit. Alternatively, the Ecodan outdoor unit can be connected up to a different size hot water cylinder via the Ecodan Hydrobox module. Intelligent Control Ecodan Hot Water Heat Pump Systems come standard with built-in Smart Energy Control. This easy-to-use interface provides homeowners with smart energy monitoring to maximise energy efficient operation. Furthermore, the advanced weather compensation feature ensures the system delivers comfortable heating no matter the season.

10 Case Study: Ngaio Renovation Project On the hills of Mount Kaukau near Wellington City is the suburb of Ngaio, where this family residence underwent a considerable makeover with the goal of significantly reducing their energy use in their newly renovated home. The Goal The owners vision was to create a modern family dwelling that was warm, dry and healthy. The first stage included upgrading the insulation levels in the ceiling, walls, and floors as well as tackling all the windows with double glazing. The second stage addressed the big energy users in the home; the heating of the rooms and hot water. Whilst living overseas, the owners had experienced the comfort and ease of a central heating system. As a result, they were especially keen on integrating radiator heating in their revamped Ngaio home. Furthermore, they were seeking an integrated solution that combined both hot water heating and space heating at the same time. The Challenge The owners bought the house with the intention to renovate. It was originally built in three phases in the ‘50s, ‘60s and ‘70s to the code and specifications of the era. This meant that the house had no insulation, no heating aside from one log burner and the thinnest single glazing on the windows. To add to this, the hot water cylinder was a low-pressure header tank fed system with a small capacity which ran out after two showers. The Solution The Ecodan Hot Water Heat Pump System chosen achieved the overall goal of having an effective and efficient whole home solution that delivers both radiator heating and hot water from the single heat pump system. The homeowners were especially keen on a central heating radiator system to cover their space heating requirements with enough capacity to ensure all the rooms were adequately heated and sufficient hot water was available at all times to meet the growing family’s needs, even in the depths of a Wellington winter. Super Efficient Ecodan Hot Water Heat Pump for Space and Water Heating An 11.2kW capacity Mitsubishi Electric Ecodan Hot Water Heat Pump System was the perfect solution to cover the daily hot water needs as well as the home’s space heating requirements at the same time. A packaged system was chosen that conveniently comes pre-plumbed and prewired. This solution incorporates a 200 litre water cylinder and the heat exchanger all in the one package. The system features fast heat-up

Stylish Radiators Used for Space Heating Eleven radiators have been installed throughout the home to provide contemporary space heating to the various rooms. Radiators are the ideal solution for responsive heating that can be mixed and matched to each room. Quick to heat up as well as turn down or off, radiator heating is easy to control room by room. The Result Having a well-insulated house with the biggest energy users in the home addressed by a high-efficiency Ecodan Hot Water Heat Pump System by Mitsubishi Electric, this family is happier and healthier than ever. Rob the homeowner explains: “I was rather surprised that radiators have moved on in their technology and we installed units with fan systems for even quicker heating. We would never go back. The Ecodan System has been the making of the house. We just don’t think about being cold anymore. We find that we are able to fully heat the house and then keep that heat rather than losing it. The system is simple to use and most impressively we have seen our power bills more than halve from our previous heating system and electric element hot water cylinder in the same home during winter. The only downside is that now we get caught out forgetting to take a coat as we don’t know how cold it is outside until we go out.” “The Ecodan System has been the making of the house. We just don’t think about being cold anymore.”
