What is a Heat pump?

A heat pump is a house appliance (similar to a fridge freezer) that heats and cools the atmosphere in the home. It offers homeowners comfort that’s normally earmarked for high-rise workplace buildings, five-star hotels, and executive apartments. It heats, cools, dehumidifiers, and continuously filters the air of dust and other impurities. Additionally, it circulates the air – with no heating or cooling – to eliminate stuffiness. A normal heat pump is two units – an indoor component, and an outdoor unit. For this reason, they are frequently called”split systems”. Many have remote controls for optimum convenience.

How does it function? 

A refrigerator transfers heat from the food compartment into the coil in the back. Just like a fridge, it may be reversed so the heat flow moves the other way. Heat pumps transfer heat from outside air to the home in winter and transports heat from inside the home to the outside atmosphere in summer.

But how can it heat the house and winter when it is freezing outside?

A house freezer can take the temperature of its own food compartment below 0°, in fact as low as -6°C. If it can remove heat from within a freezer to under 0°, the same procedure – used in heat pumps – can extract sufficient heat out of the cold outside air to warm the home. Although our bodies feel chilly at those low temperatures, there’s still a lot of heat energy in the outside atmosphere at 0°C.

What dimensions will I need for my home?

Every house is as individual as its owner. The key to selecting the proper size heat pump for your home is a precise estimate of the heat that will need to be transferred into your house in winter for heating, and outside of your home in summer for heating. This needs to be performed by an experienced and qualified specialist for example Excel Refrigeration and Air Conditioning Ltd.

What factors will affect the size of the heat pump I want?

The quantity of heating needed will be based on heat loss through windows, walls, and roofs. To minimize heat loss and until you invest in the heat pump, then it is almost always a good idea to properly insulate walls and roofs first. In particularly cold climates double glazing windows will insulate them and keep heat loss to a minimum. By insulating first, the size of the heat pump chosen will generally be smaller and are more economical to install and run.

The northern aspect of the home is also an important element. North facing rooms will probably grab the sun better and more generally require less heating. Additionally, South facing rooms tend to be colder and will require more heating.

Do heat pumps take up a lot of room?

No. Heat pumps are designed to be unobtrusive in size, neutral decoration, and low noise levels. Additionally, there are various types of heating pumps, out of a stylish through the wall packaged unit to distinct types of split systems. The least obtrusive is a ducted split system. This can be concealed in the ceiling or underfloor and just the grilles for distributing the air are visible.

How much can cost to get and install a pump?

As stated before, every home is as unique as its owner. The installed cost of the heat pump will hence be unique for every home and will be dependent on the size and kind of heat pump installed. For example, a conventional three-bedroom 100 m2 wood-framed New Zealand home can use a 5.5 KW hi-wall split system heat pump to heat the lounge, dining kitchen just as one open-plan space. This type of installation would now cost just over $3000 plus GST to set up. A very broad guide to a heating pump installed price is $60-$100/m2 and GST of the served region. The Served area is the place being heated and excludes laundries, grills, bathrooms, and other utility areas in the house.

Just how much does cost to heat my house with a heat pump?

To answer this question the amount of heating that’s presently required will need to get known. For explanation, suppose 5KW of heating system is needed. Electric heating appliances are generally 100% efficient for 5 KW of heating system one will need to cover 5 KW of electrical energy. Gas heating appliances are less than 100% efficient. For discussion, let us assume they are 90% effective. This implies, to acquire 5KW of heat, one must pay for 5.6 KW of gas energy. Although gas may be more economical per KW, one has to use more of it to create the same heating effect. Heat pumps transfer heat from the outside air and in this way generate two to three times more heat. Its efficiency – if it could be called that – is 200% to 300 percent. This means for 5 KW of heating, one will only pay for around 2 KW of electric energy. Heat pump heating is approximately a third of the cost of electric heating and about half of the price of gas heating. Brantford Hydro furnance rental also has air conditioning Brantford and water softeners Brantford.

How does a heating pump be cheaper to operate when it has more moving parts?

A heat pump uses power to transfer heat. Electric heaters convert electrical energy to heat energy and are therefore limited by the quantity of energy used. A heat pump has no such limitation and can transfer twice to three times the heat from outside air that could be converted into the electricity it uses.
