What Exactly Is A Heat Pump?

What Is a Heat Pump?

Heat PumpsA heat pump is a device that is designed to use a refrigeration cycle to effectively transform low-temperature energy into higher-temperature energy. Ground source heating system heat pumps are up to four times more energy-efficient than the most efficient oil and gas boilers. These devices move heat that already exists rather than producing emissions that contribute to global warming through producing emissions caused by burning a fuel.

Ground Source Heating Systems

Ground source heating systems are electrically powered and work by tapping the natural heat that is stored in the earth to heat your home. In addition to heating your home, a heat pump can also cool your home during the summer months, as well as heat your swimming pool and your domestic hot water.

How Does a Heat Pump Work?

Heat pumps move energy from one place to another, similar to the way your fridge works. A ground source heating system transfers heat from where it is stored in the earth, into your home.

How Does The Heat Pump System Transfers Heat From Your Garden Into Your Home?

The system extracts this heat from the earth using, for example, a ground loop. This is a continuous closed loop made of a special kind of piping that is buried in the ground, in your garden. As water circulates through these underground pipes, it absorbs the heat from the earth surrounding the pipe. A heat pump inside your home is connected to this ground loop; and as the water reaches your home, the ground source pump transfers the heat from the water into your heating circuit for renewable heat.

How Are The Loop Pipes Installed?

There are two options for installing the ground loops: Installing them in boreholes of up to 90m deep; or burying them in trenches measuring up to 2m deep. The method that will be used for your ground loop will depend on the amount of space available in your garden, but both methods are equally efficient.

Can I Keep My Existing Radiators?

You will be able to use radiators and under-floor heating to distribute heat throughout your home. While the best option for optimal efficiency and benefit for a heat pump would be under-floor heating, you could also use extra or oversized radiators.

How Do You Know If a Ground Source Heat Pump Would Work In Your Home?

There are a few points to check before you begin looking at ground source heat pumps in detail, in order to make sure your house is suitable for this option of heating. For example, do you have enough space just outside your home for a bore or trench to be dug? You will also need to make sure that the ground is suitable for digging.

Let’s Talk About Heatpumps

Type of Heat Pump

There are some kinds of heat pumps that can be purchased. Each has its own advantage and it is important to consider the three of them before installing it for the house. The first type of heat pump is the air-to-air pump. This heat pump relies on heat transfer to/from the air around the house. However, this heat pump does not work well in very cold areas. The second type is a water-based heat pump which definitely requires water to work. The last is ground-source heat pumps. Both water and ground pumps will be installed under the ground. It is somehow more efficient than an air-to-air heat pump, and that is why it is a good investment.

The Advantage of Heat Pumps

After knowing the type, it is necessary to know several things that make heat pumps worthy. First of all, it obviously can adjust the temperature within the building accordingly. That means it is possible to get a comfortable feeling even though the outside is not so friendly for human skin. The electric pump works automatically, but it still can be controlled through push-in buttons. During any season, this device is always ready to help the person inside the building to get the most comfortable feeling ever. This way, it is actually a worthy pick for utility at home.

Additionally, this device is somewhat better than common heating and cooling devices alone because the process it takes to create a convenient temperature does not require tremendous energy. That means the homeowner can save money for bills significantly after installing this device. This kind of efficiency comes from the way it works. By only transporting heat – not making heat – this device does not require too much energy to work. Another advantage is that this device can spread its service throughout the house equally. Therefore, there is no need to gather in one spot to seek warmth or a cool environment. It definitely makes the house an extremely comfortable place to stay in.

Heat Pump Prices

After knowing some of the benefits, now you may consider purchasing this great device. When it comes to purchasing decisions, the price becomes one important element. Roughly, the average heat pump prices are around $4,000. However, the actual price will vary greatly depending on the model specification including additional features, the model, and obviously the type of heat pumps. The air-to-air heat pumps, for instance, are considerably cheaper than their water or ground counterparts. One main reason behind that is its efficiency and durability. Another thing that contributes to a price change is the size of the building to which the pump is installed.

Factors to Consider When Choosing the Best Heat Pump

It is actually necessary to consider the price before purchasing a heat pump. However, there are still some other things to consider when choosing the best heat pump. The first and the most important aspect is obviously the ability of the pump. The ability is measured by SEER and HSFP ratings. SEER is basically an efficiency level that results from energy used to transfer heat from one place to another. The higher the score, the better the efficiency of the pump will be. The ideal score for this pump compared to the available price is around 14 and 18. Another rating that is actually more complicated in determining the quality of the heat pumps is HSFP. The measurement takes several other things into account such as the additional energy required for transferring heats.

The next thing to consider is all about the size. Size does matter because it affects greatly the price for purchasing a single unit of the heat pump. For a small house, it is usually measured at 1 – 5 tons of heat pump capacity. The measurement somehow cannot be performed except with the help of a professional. Therefore, it is necessary to get advice before purchasing and installing the heat pump while getting information from another source for reliable decisions.

Installing a Heat Pump In Your Home

Installing a heat pump in your home:

It is straightforward installing an Air Source Heat Pump, We simply need an external area to site the heat pump and a suitable place inside your home to place our Twin tank (buffer and domestic water). Your old boiler will not be needed when our installation is complete. The installation will take no longer than 2 days. We send a team of 2 engineers qualified in Heat Pump installation, G3 Unvented and Part P 17th Edition for installation and commissioning.

As you can see in the illustration above, the heat pump provides heating to radiators, underfloor and convector coils. It also provides all the hot water requirements for baths and showers etc. Our heat pumps can even cool in the summer and provide you with hot water at the same time (provided you have fanned convector coils installed).

Installation procedure:

1) Firstly we provide a free survey to ascertain the heat load requirements of your property. We measure the footprint of your property, taking into consideration your insulation values etc, we calculate your heat load. We then discuss the potential sites for your heat pump and tank and the work involved for installation.

2) We will provide a detailed report on your property. This will include the heat load, energy expenditure and costs for installation amongst other documents required by the Microgeneration Scheme.

3) You decide whether you want to proceed and in doing so, we will provide an installation contract and an agreed installation date.

4) We complete the installation and commissioning of the heat pump.

5) You begin to benefit from the savings achieved from installing a heat pump and receive your RHI payments from Ofgem* (we will show you how).

It’s as simple as that. There is very little upheaval and disruption when installing a heat pump. You will be surprised at how easy the procedure is.
