• Tough In Cold Temperatures. Rated to perform well down to -25 degrees Celsius, this unit has the lowest minimum operating temperature out of all THERMA V Monobloc models.

Cons

What might make someone choose a different model? Here are a couple of things to keep in mind:

• Flow Rate Errors. Some owners of the THERMA V Monobloc R32shave reported experiencing 'CH14' or flow rate errors,  which can cause the system to malfunction.
• Higher Discharge Temperature. The refrigerant used in theTHERMA V Monobloc R32 is known to have  a higher discharge temperature than other models.

THERMA V New Split

The THERMA V New Split is a more recent model that builds on the success of the original THERMA V Split. Unlike the all-in-one Monobloc, this system is separated into two individual indoor and outdoor units. It manages temperature throughout the home by zones, so different areas can be set to different temperatures.

This is ideal for those who want more control over their heating and cooling, or for larger properties. With an ErP rating of A+++ and a noise level of 20 - 45 dB, this unit is among the most efficient and quiet on the market.

Pros

The following are some of the reasons why  homeowners choose the THERMA V New Split:

• Flexible Zoning. The ability to set different temperatures in different areas of the home is a major selling point for the THERMA V New Split. This is perfect for larger homes or for individuals with specific heating needs.
• High Capacity. The THERMA V New Split has a high capacity of up to 100% at temperatures as low as -7ºC, making it perfect for even the coldest winters
• Great Seasonal Coefficient Of Performance. The THERMA V New Split has a great Seasonal Coefficient Of Performance (SCOP) of 4.65 in heating operation.

Cons

Some things to keep in mind as you consider this model include:

• Installation. The installation process for the THERMA V NewSplit can be more complicated than other models, as it requires two units rather than one.
• Cost. The THERMA V New Split is usually more expensive than other models, due to its increased capacity and features.

THERMA V Split – High Temperature

The THERMA V Split also comes in a High Temperature model, which is specifically designed for applications that necessitate stronger heating power. It's commonly used in older homes, less insulated properties, and refurbishment projects to mitigate and replace the warmth they would otherwise lose with a conventional system.

The THERMA V Split High Temperature model can reach a maximum hot water temperature of 80°C in dual refrigerant systems, and up to 65°C with a single refrigerant system. As with the standard THERMA V Split model, this unit comes with two parts, including an external unit that can be installed up to 10m away from the property for greater flexibility.

 Pros

These are some of the reasons why the THERMA V Split High Temperature might be the right choice for a homeowner:

• High Hot Water Temperatures. As the name suggests, one of the key selling points of this model     is its ability to heat water to high temperatures – up to 80°C.
• Flexible Installation. The external unit can be installed up to 10maway from the property, giving homeowners greater flexibility when it comes toinstallation options

Cons

Some things to keep in mind about the limitations of this model include:

• Limited Performance In Extreme Cold. This model does not perform as well in extremely cold temperatures, so it might not be the best choice for homes in colder climates.
• Higher Running Costs. The THERMA V Split High Temperature model has higher running costs than other models due to its increased heating capacity.

Why an LG Heat Pump?

There are many reasons to choose an LG heat pump for your home or business. LG is a world leader in manufacturing high-quality, energy-efficient appliances, and their heat pumps are some of the best on the market.

Some of the benefits of choosing an LG heat pump include the following.

• Exceptional performance: LG heat pumps are designed to deliver high levels of heating and cooling efficiency, even in extreme temperatures.

The Cost Of It All

LG heat pumps are some of the most popular models on the market, and they come in a variety of types to suit different needs. The average cost of installing an LG air source heat pump system is around £6,000 – £12,000. Several factors affect the total price you can expect to pay.

The model and size of the heat pump: The model you choose will affect the cost, as some models are more expensive than others. The size of the heat pump is also a factor, as a bigger unit will typically cost more to install.

The type of system you need: The type of system you need will also affect the cost. If you need a more complex system with multiple units, for example, it will cost more than a simpler system.

The installation: The installation is another factor that can affect the total cost. If you need to have multiple units installed, or if you need specialised equipment, expect a somewhat higher price.

Be aware that you may be able to get a grant from the Renewable Heat Incentive (RHI) to offset some of the costs of a new LG heat pump. The RHI is a UK government program that provides financial incentives to encourage the uptake of renewable heat. You could get up to £12,600 back through the RHI over seven years.

When it comes to choosing the right heat pump for a home or other property, there are a variety of factors to consider. The size of the property, how much heating power is needed, and the household members’ personal preferences will all play a role in the decision-making process. But regardless of which specific model you choose, an LG air source heat pump is a great way to enjoy efficient and cost-effective heating in your home.
