What is a Heat pump?
A heat pump is a home appliance (similar to a fridge freezer) that heats and cools the climate in the home. It offers home owners ease that is usually reserved for high-rise office buildings, five-star hotels and administrative apartments. It heats, cools, dehumidifies and continuously filters the air of dust and other impurities. It also circulates the air - without heating or cooling - to eliminate stuffiness. A typical heat pump is two units - an indoor unit, and an outdoor unit. For this reason, they are often called "split systems". Many have remote controls for maximum convenience.

A fridge transfers heat from its food compartment to the coil at the back. Like a fridge, it can be reversed so that the heat flow goes the other way. Heat pumps replacement heat from face air into the home in winter, and transfers heat from inside the home to face air in summer.
But how can it heat the home and winter when it is freezing outside?
A home freezer can take the climatic characteristic of its food compartment below 0°, in fact as low as -6°C. If it can remove heat from inside a freezer to below 0°, the same process - used in the heat pumps - can passage adequate heat from cold face air to warm the home. Although our body's feel cold at these low temperatures, there is still a lot of heat vigor in the face air at 0°C.
What size will I need for my home?
Every home is as private as its owner. The key to selecting the right size heat pump for your home is an accurate evaluation of the heat that will need to be transferred into your home in winter for heating, and out of your home in summer for cooling. This needs to be carried out by an experienced and excellent master like Excel Refrigeration and Air Conditioning Ltd.
What factors will affect the size of heat pump I need?
The number of heating needed will depend on the heat loss straight through walls, windows and roofs. To minimise heat loss and before you spend in the heat pump, it is always a good idea to properly insulate walls and roofs first. In particularly cold climates duplicate glazing windows will insulate them and keep heat loss to a minimum. By insulating first, the size of heat pump premium will generally be smaller and therefore be economy to setup and run.
The northern aspect of the home is also an leading factor. North facing rooms will catch the sun good and more generally need less heating. Conversely, South facing rooms tend to be colder and will need more heating.
Do heat pumps take up a lot of room?
No. Heat pumps are designed to be unobtrusive in size, neutral decor and low noise levels. There are also separate types of heat pumps, from a approved straight through the wall packaged unit to separate varieties of split systems. The least obtrusive is a ducted split system. This can be secret in the ceiling or under floor and only the grilles for distributing the air are visible.
How much does cost to buy and setup a pump?
As stated before, every home is as unique as its owner. The installed cost of the heat pump will therefore be unique for each home and will depend on the size and type of heat pump installed. As an example, a accepted three-bedroom 100 m2 timber framed New Zealand home may use a 5.5 Kw hi-wall split theory heat pump to warm the lounge, dining and kitchen as one open plan area. This type of facility would currently cost just over 00 plus gst to install. A very broad guide to heat pump installed cost is -0/m2 plus gst of served area. Served area is the area being heated and excludes laundries, garages, toilets and other utility areas in the home.
How much does cost to heat my home with a heat pump?
To answer this interrogate the number of heating that is currently principal will need to be known. For the purpose of explanation, assume 5Kw of heating is needed. Electrical heating appliances are usually 100% efficient so for 5 Kw of heating one will need to pay for 5 Kw of electric energy. Gas heating appliances are less than 100% efficient. For discussion, let's assume that they are 90% efficient. This means, to gain 5Kw of heating, one has to pay for 5.6 Kw of gas energy. Although gas may be economy per Kw, one has to use more of it to yield the same heating effect. Heat pumps replacement heat from face air and in this way produces two to three times more heat. Its efficiency - if it can be called that - is 200% to 300%. This means for 5 Kw of heating, one will only pay for colse to 2 Kw of electric energy. Heat pump heating is approximately a third of the cost of electric heating and about half the cost of gas heating.
How can a heat pump be economy to run when it has more enchanting parts?
A heat pump uses electricity to replacement heat. electric heaters turn electric vigor to heat vigor and are thereby petite by the number of electricity used. A heat pump has no such limitation and can replacement twice to three times the heat from face air than can be converted from the electricity at uses.
Are heat pumps noisy?
No, they are generally not noisy. The source of the noise in a typical heat pump is air impinging on the grille as it is forced out of the unit. Air noise is marginally higher than ambient background noise and is usually not distracting.
Do they dry the air: like on an airplane?
Heating or cooling air changes its characteristics. Heating air increases its ability to carry moisture and suspension by reducing its relative humidity content. This is the same process used in clothes dryers. Cooling air causes the moisture in the air to condense out of suspension. This reduces the absolute humidity content of the air and is the process used in the humidifiers. Whether way, reducing moisture in the home is useful by discouraging mould and mildew by producing a healthier living environment.
Are they reliable?
Yes. Heat pumps are reliable. They use the same process as the home fridge or freezer and have the same level of dependability and useful life expectancy.
How easy are they to repair?
Provided the aid person is experienced and qualified, repairing heat pumps is as easy as repairing the fridge or freezer. For repairs, talk to Excel and Refrigeration and Air Conditioning Ltd.
Do they need servicing?
Like cars, heat pumps should be usually serviced for optimum operation. This involves cleaning the air filter and possibly checking that the refrigeration payment is correct. It would be a good idea to aid the pumps just before the beginning of each ultimate season i.e before winter and again before summer.
How are heat pumps good than other forms of heating?
Apart from being economy to run, heat pumps offer other benefits that heating only systems cannot.
1) Heat pumps don't burn oxygen or create stuffiness like open fires do. They are designed for all year round comfort, not just for four months during winter.
2) They yield low-density heat which is safer for children and elderly, unlike fires, oil filled or electric fan heaters.
3) They are unmatched for convenience and ease-of-use.
4) They do not pollute their climate with the products of combustion, and they use ozone friendly refrigerant.
All in all, heat pumps offer the best venture in home heating and comfort.
