DOMESTIC AIR CONDITIONING
will save energy with continued operation, especially if underfloor heating is installed. Next, suggest to your customer to purchase
a unit which has programmable temperature settings meaning they can set a precise temperature and schedule a reduction in temperatures when they leave, thus cutting energy bills and is much better for the environment, by eliminating energy wastage. Lastly, on the importance of having their ASHP serviced regularly to prolong its longevity and efficiency. To do this, those who have opted for a heat pump solution should regularly clean the filters. Customers don’t always understand what is needed to maintain such a device, so ahead of purchasing a unit they should ask the manufacturer or seller ‘what level of maintenance care is needed’.
is available with many types and styles of air conditioning indoor unit.
Commercial systems There are also solutions for commercial buildings or apartments where large centralised systems can be shared to provide efficient water heating solutions, utilising Variable Refrigerant Flow (VRF) technology with multiple Hydro Units (essentially a large ASHP with multiple hot water production capabilities) and the ability to also provide cooling. Samsung offer two types of Hydro unit, one with 50oC and the other with 80oC outputs and they can both be connected to Heat Recovery VRF systems, thereby recovering the waste heat from indoor units in cooling operation to heat water. In addition, both types can be combined on one system as a cascade type solution to maximise the efficiency of hot water production.
Domestic Hot Water tank solutions In addition to the large range of domestic hot water cylinders on the market, ASHP manufacturers have their own alternatives, including combination hydro unit and water tank solutions. The Samsung ClimateHub is one such solution. It looks very much like a fridge freezer and can be installed very unobtrusively in a utility room, an airing cupboard or even in the garage.
Size means everything When it comes to selecting a suitable heating system for your customer, size matters and is incredibly important when it comes to efficiency. A unit too large will not run at its most efficient, which will drive up the energy bill, a unit too small may struggle to maintain

the set temperature - the unit needs to be in the ‘Goldilocks zone’, sized just right. The correct sizing of the heat emitters, radiators or underfloor heating is also an essential element to providing the most efficient solution. Air Source Heat Pumps can provide water at temperatures equivalent to a conventional boiler but work more efficiently at around 50°C or below, so existing radiators may have to be replaced with slightly larger or deeper ones.
As a rule of thumb, we would recommend the following heating solutions for residences large or small: ■ Apartment living: A centralised VRF system with associated Hydro Unit(s) or an individual ASHP system (if there is a suitable area to site an outdoor unit)
■ Homes: An individual ASHP system with hot water tank
Educating your customer Both you, and your customer, should consider the Seasonal Coefficient of Performance (SCOP) value that your chosen solution holds. The SCOP measures the true energy efficiency of a heating technology and running costs can be estimated over an entire year. This new measure gives a more realistic indication of the energy efficiency and environmental impact of a system on the home and is reflected in their energy rating, similar to other consumer electronic devices. E being the worst and A+++ being the best. Once you have established the most efficient model for the job, the next step is educating customers on its operation. Air Source Heat Pumps work more efficiently if left running 24/7. This is counter intuitive to normal boilers and especially hard to convince customers they
Taking control Energy is 40% of the life costs and 50% of the running costs of a home. Managing these costs effectively requires controls. In the search for energy savings within a home, identification of wasted energy is one of the best ways to reduce operating costs, cut CO2 emissions and deliver greener living. With many homes now equipped with smart
technology, such as Alexa or Google Assistant devices, by recommending purchasing a Wi-Fi enabled unit means the customer can adjust the temperature by using their smartphone. For 2020 Samsung have introduced fully
integrated plug and play indoor units which simplify installation and provide simple control. There are optional Wi-Fi control options using the Samsung SmartThings platform. Other features include energy monitoring for users to keep track of their energy use, and conveniently manage and monitor single or multiple climate systems from a central, remote location. Samsung Controls and Accessories give you optimum authority, so you can manage singular or multiple units with ease and efficiency – saving energy, reducing maintenance costs and extending the lifespan of your units.
Last say
Overall, from the first stages of being briefed on a new project – be it residential or commercial – the overriding question is what type of climate solution they require. Once this has been established, an efficient and bespoke solution can be proposed, installed, and energy consumption can be reduced. This in turn, will hugely benefit the
environment, slow climate change and ensure a more energy efficient space.
