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.

Solar thermal panels work by capturing heat directly from the sun and using it to heat water. This hot water is then passed through a coil to heat the water for your central heating system. Solar thermal systems are compatible with many existing conventional boilers with hot water tanks, and can be set up to feed in to your existing heating system.

Air source heat pumps can be a really efficient way to generate heat. Although they require electricity to run, they generate much more heat than an electric heater that uses the same amount.

Air source heat pumps provide heat at a lower temperature than most other types of space heating. This means they’re most efficient when they’re left on for longer periods of time, and distribute heat through wet heating systems with large surface areas, like underfloor heating or big radiators.

Air source heat pumps can be much more efficient than oil and LPG boilers, and older electric heating systems. However, they’re only usually the most efficient option if your property is very well insulated.

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.

Tesla’s top-of-the-range battery storage system is still one of the most expensive on the market. It has a huge 13.5kWh usable capacity and can even keep you up and running during a power cut. But how long does a Tesla Powerwall battery last? And does this mean it’s worth investing in one?

The Tesla Powerwall 2.0 comes with a 10-year warranty. But Tesla says that it should last way beyond this – at least 5 years longer. The standard warranty says that it should work at 70% capacity for the full 10 years – so if it loses more than 30% of its storage capacity within that time, it should still be covered.

While the Tesla Powerwall does last a long time, it has a large capacity that most average households won’t require, and it’s a costly option. After installation, the Powerwall 2.0 will set you back between £6,500 and £9,000, so ideally you want it to last past its 10-year warranty.

Before you splash out, consider the size of the solar panel system you want to install or you already have. Will it generate enough electricity to make it worth storing in the Powerwall? If not, are you expecting to upgrade your solar panels to a larger system in the future? If you are, then it might be worth investing in a Powerwall. It might also be better to wait until you come to upgrade your solar panels – the solar battery price trend is going the same way as solar panels, so they will probably continue to decrease in price as more people adopt the technology.

How Many Solar Panels And Batteries To Power A House?

Do you wish to know the number of solar panels and batteries sufficient for a house? Well, this is a frequently asked question in the solar world which would be very difficult to provide an accurate answer. This is basically down to the fact that all homes are unique with different sizes as well as amount of daily energy requirements. As a result, the number of solar panels and batteries needed would be unique to the house in question. However, we’ll consider the varying influencing factors that will go a long way to help calculate the number of panels and batteries needed to power a house.

First and foremost, let’s take a look at the solar panels. You’d have to start here by putting into consideration all household appliances that makes use of power in the house to get a good idea of how many that’ll be needed.

• How Many Watts Is Being Used In The House On A Daily Basis?

To determine this, simply go through your utility bill for kilowatt-hours (kWh). This varies amongst homes and being able to identify your daily average energy usage will assist you in getting your solar needs.

• What Is The Number Of The Peak Sunlight Hours At The House’s Location?

Having in mind that the solar panels only work when under direct sunlight, the first step to determine the peak sunlight hours. Once determined, you can then multiply the figure in hours by the house’s hourly energy usage and divide by the solar panel’s wattage.

Overall for a 1500 square foot house, the number of solar panels that’ll be required should fall around 15 to 18.

Meanwhile for batteries, there are also some factors to be considered to determine the number of batteries that is required to power a house. These factors include the house’s power or electricity usage, the period of time in which the battery will be used as well as the battery’ specifications.

It may be hard to believe with the summers we have in the UK, but there is more than enough sunlight to power solar panels. Solar PV (photovoltaic) panels operate in daylight, rather than needing direct rays from the sun so they’ll work throughout the year.

If you look after your air source heat pump, it can last for over 20 years. Make sure you check it every year and get a registered or qualified installer to check it every 3-5 years to prolong its life. If in doubt, check the manufacturer’s maintenance instructions.
