HOME & HEATING
Choosing the right heat pump for your home
Whether it be a new build, or a retrofit, most homes include at least one heat pump, if not a whole heating solution. They can provide cheap, clean heat and are much more convenient than a log burner as you just need to press a button. But how do you decide what is best? Choosing the right sized heat pump is key to ensuring optimum comfort levels. Every situation varies and it is therefore important to get professional advice from heat pump experts. The range varies from wall mounted high walls, floor mounted systems, multi systems, ceiling cassettes, right through to ducted central heating systems allowing you to have a very discreet way of heating your whole home to a constant temperature throughout. Firstly, you must select a heat pump that is suitable for the size of the space you wish to heat. Usually a site visit is the best way to ascertain this. Not only is the size of the area taken into consideration but also, insulation, building orientation, windows and ceiling space. There are a wide range of heat pumps available with different heating outputs so it is important to select the correct size for your requirements that will handle the job but not be unnecessarily overpowered. Secondly, the location of your heat pump is also extremely important. The cheapest installation is a back to back where the outdoor unit is positioned directly behind the indoor unit however this is not necessarily always the best option. It is vital that the indoor unit is positioned in a place that will not be
constantly blowing on you. Also important, is the location of the outdoor unit. Most people do not want their outdoor unit sitting directly in their outdoor entertaining area or right outside their bedroom window. Choose a brand you can trust. Many brands have come and gone over the years but there are a number of manufacturers who provide reputable and reliable products. All brands vary in their energy efficiency, quietness of systems and price, so it depends on your application as to which will be most suitable. Major brands such as Panasonic, Fujitsu, Mitsubishi, Daikin, Toshiba and Hitachi are all reliable brands backed up by good technical after sales service. Ensure your heat pump is installed by an accredited installer. This will not only ensure correct installation of your heat pump, but also validate the manufacturers warranty. Other things to consider when choosing a heat pump are time clocks, ease of use of the remote controllers, air filtration and also wifi capabilities.

The facts about home ventilation Balanced Pressure vs Positive Pressure Under the New Zealand Building Code, all buildings, including residential, need to be suitably ventilated, either with opening windows or forced ventilation. Clause G4.1 states: “The objective of this provision is to safeguard people from illness or loss of amenity due to lack of fresh air.” There are many benefits to forced, or mechanical, ventilation over opening windows, including warmth, security, reduction of outside noises and reduction of condensation. Traditional domestic ventilation systems are ‘positive pressure’. They bring air in from outside via the roof space and force the stale air out through gaps around windows and doors. The incoming air from these systems has to be heated or cooled to keep the house warm in winter or cool in summer. The Smooth-Air HEX390 is a ‘balanced pressure’ system. It extracts air from the house and at the same time brings in fresh air. These two streams of air pass through a heat exchanger, which warms incoming air in winter and cools in summer if air conditioning is being used. This means that up to 80% of the energy which would be

wasted using a traditional positive pressure system is recovered, resulting in significant energy savings and therefore lower heating or cooling costs. Until recently, balanced pressure ventilation systems have been considerably more expensive than traditional positive pressure systems. However, with Smooth-Air’s unique manufacturing capabilities, a HEX390 balanced pressure system can be installed for a similar price as a traditional positive pressure system.
