- What is a Heat Pump?
Heat pump units also allow the cooling cycle to be reversed.
A heat pump extracts free heat from the outdoor air, even on the coldest days when the outside temperature may fall as low as -10C, and transfers the heat indoors.
Heat pump units therefore avoid the need for a boiler and allow you to cool and heat with the same unit, resulting in cost and energy savings throughout the year.
A simple principle developed to perfection, air conditioning works like your refrigerator which removes heat continuously from the cabinet and discharges it into the kitchen. You can feel this free heat by touching the coil on the back of your refrigerator.
In summer, the heat pump extracts heat from the warm air in your home and pumps it outside - and your home stays comfortable & cool.
In winter, the reverse happens. Natural heat in the outdoor air, even when it's freezing, is extracted and moved indoors - giving you wonderful warmth when you need it. This comfort costs less: three kilowatts of heat for each kilowatt of electricity used!
Heat pumps are up to three times more economical than conventional gas fired or electric central-heating systems. Even in bitter cold snaps you will save money. Installation costs are lower too. With just one system, for cooling in summer and heating in winter, you save on equipment outlay.
- How long does it take to install?
In most circumstances, a single or twin split application can be installed in one day, with minimum disruption.
- What are the benefits of air conditioning?
The benefits of air conditioning are to give a comfortable environment at home throughout the seasons, Spring, Summer, Autumn and Winter.
An air conditioning unit can have two functions - heating and cooling. With an auto changeover switch on most new units, you set the temperature and the unit will cool or heat as required automatically.
- Do the units make a lot of noise?
The units are exceptionally quiet and ideal if you want climate control in your bedroom for example. An ultra low-noise night time setting can be switched on using the remote controller.
- Why bother with yearly Planned Maintenance?
Yearly preventative maintenance is a wise thing. A properly maintained system will not only ensure that it performs at peak efficiency, it will also save you money on your energy bills.
A properly maintained system also lasts longer. During a preventive maintenance, certain parts that can cause trouble when they are dirty are cleaned to keep the system running smoothly and efficiently.
A maintenance service also includes inspection of your system. So, any problems can be discovered before serious damage occurs and before you find yourself without air conditioning in the middle of summer or winter when you need it the most.
- How much will it cost to run?
Heat pumps offer numerous advantages as a heating solution. The same systems used to cool can also be used to heat, resulting in less initial investment and simplicity in operation and maintenance.
Heat pumps also have an important advantage in the area of efficiency. Unlike fossil-fuel based heating systems, heat pumps extract available heat from the outside air. Heat pumps offer efficiency gains on the order of approximately 3:1 and higher, compared to electrical heating.
So, for every unit of energy consumed by the heat pump, three or more units of heat are gained.
If you have a 3.5kw heat output the power input will be 1.2kw. Multiply this power input by the length of time the unit runs and the cost per unit of electricity, and you will end up with your running cost.
- Will I pay VAT (Value Added Tax) at the normal rate?
Under new government legislation applicable since April 2005, if we supply and install an air conditioning system which operates as a heat pump to your home, you only pay 5% VAT.
