Ground Source Heat Pump in Rowland's Castle

Are you currently considering installing a ground source heat pump in your home? Well, a heat pump can be a great alternative when compared to gas or oil boiler, however, you may also be worried about the operating efficiency of this heating system if you live in a cold climate or during the winter months. However, in reality, there’s nothing to be worried about!

A ground source heat pump works by incorporating the natural heat that’s typically found in the ground or groundwater. In other words, this type of heat pump doesn’t make use of fossil fuels to heat your home while it can also minimize carbon emissions that may pose a huge risk to the environment. This makes a popular option especially amongst home and property owners who are very environment conscious and prefers to utilize more renewable sources of energy.

However in a place such as the UK where the temperature can drop to around -10℃ during the winter months, it may get you thinking whether there’ll be enough heat in the ground to warm up your home. Let’s have a look.

In the UK, the temperature of the ground doesn’t normally fall less than 10℃. This is still enough heat for the ground source heat pump to warm up your home. In other words, as long as you purchase the right one, your ground source heat pump will continue to work just fine during the cold months. Due to the fact that every heat pump varies, you will need the right equipments so as to ensure the heat pump works well throughout the winter. This is usually not an issue in the UK, but same can not be said of colder places like Canada and North America.

When people think about heat pumps, they’ll automatically have the believe that a swimming pool will require a big heat pump. Since the swimming pool has a large volume of water, then warming such a volume will require a large ground source heat pump because that volume is much larger than the normal domestic hot water tank, right? Well, that point of reasoning does seem logical especially with the information almost everywhere that ground source heat pumps are usually less efficient when it comes to heating hot water for home’s use. However, the fact is there are also some things to put into consideration that also works in favour of the ground source heat pump.

First and foremost, you should know your domestic hot water will typically be heated to a much higher temperature when compared to your swimming pool. Since you wouldn’t be using the water to disinfect your bathroom or doing your dishes in your swimming pool, then the temperature can be much lower. In fact, it’s much more comfortable and enjoyable to heat to a typical “swimming pool temperature than having it at a hot bath temperature. If you’ve ever wandered into a really hot swimming pool, you wouldn’t need any introduction to the painful discomfort that comes next.

As a result of this low temperature, your “tiny heat pump can operate a in a more efficient way which makes the use of ground source heat pumps a viable swimming pool heating option. What’s more? The ground source heat pump works for a swimming pool just like any any other application - moving the heat from the region of a warmer temperature to the cooler temperature region.

The bigger the ground source heat pump, the better right? Wrong! And you’ll definitely be sorry to make such a huge mistake. When planning to install a heat pump, determining the size of the ground source heat pump is not as direct and straightforward as many homeowners would think. Here, you’ve got only a small margin for error. When the pump is too small, the heat pump will make use of the backup heater too often and in the event whereby the heat pump is too big, it’s going to short cycle. Both situations are preferably avoided as they’ll both leave you with an expensive and inefficient system.

To get the accurate size of a heat pump, there’s usually the need to hire the services of an expert and licensed heat pump installer who possesses a top notch design calculation software. In reality, the majority of inefficient systems are caused by a lack or poor understanding of the suitable design software.

There are many factors that can influence the calculation of a home’s heat pumps size. These includes

✓ Radiators and underfloor heating sizes

✓ Insulation, property fabric as well as heat loss

✓ The number of rooms in the property

✓ The types of rooms and their uses.

✓ The desired indoor temperature for varying rooms

✓ Seasonal temperature fluctuations.

Generally, a bigger house will require a bigger ground source heat pump. With an eye on the age of the property, heat loss as well as the types of the rooms, a house of about 100 square metre can require up to 4kW ground source heat pump. And for a house that’s about 200 square metre, the ground source heat pump also doubles to 8kW.

So do you wish to take advantage of the heat generated by the ground to warm up your home by getting a ground source heating pump? If yes, then you’d also probably be wondering how much a ground source heat pump is going to cost so you can set a budget and start planning.

Installing and running ground source heat pump can cost between the range of £600 to £700 to run on an annual basis, meanwhile it can cost you within a range of £13,000 to £19,000 to have installed. However, you should take note that these prices can be by varying influencing factors such as the size of the installation as well as any other extra work that may needed to complete the job.

When it comes to estimating the time it takes to recover the initial cost of the system via energy savings, nothing is certain as this can be very hard to determine or predict. The main reason for this is due to the fact that it’s dependent on the efficiency of your heating system, the type of system you’re replacing ( whether or not you qualify for Renewable Heat Incentive -RHI payments ), the efficiency of your home’s insulation, how efficiently the system’s controls are being used and how the heat generated from the ground source heat pump would be put to use. However, to figure out how much you’ll save, the type of fuel replacing is perhaps the most essential. For a four bedroom detached house, you can save between a range of £1,200 to £1,300 for a LPG fuel replaced, £1,400 to £1,500 for an electricity fuel replaced, £600 to £700 for an oil fuel replaced and finally, £200 to £300 for a solid fuel replaced.
