LG heat pump product range
LG offers a range of air source heat pump systems in the UK under their most popular THERMA V product line. Newer models boast a refrigerant R32 which has 68% lower global warming potential than older refrigerants and functions in extremely cold temperatures as low as -25°C.
| Model series | Type | Power output range | Energy class | Max water temp | Min outdoor temp |
|---|---|---|---|---|---|
| THERMA R32 Monobloc S | Air to water | 5-16 kW | A+++ | 65°C | -25°C |
| THERMA R32 Split | Air to water | 4-16 kW | A+++ | 65°C | -25°C |
| THERMA High Temperature | Air to water | 9-16 kW | A+ | 80°C | -25°C |
| THERMA Hydrosplit | Air to water | 5-16 kW | A+++ | 65°C | -25°C |
The Monobloc S is particularly popular due to its exceptionally quiet operation – as low as 32dB, which compares to a human whisper. These systems are also equipped with inverter-controlled compressors that adjust their speed to your household's demand, and this way, optimise energy efficiency.
Additionally, LG offers a 7-year warranty plan, provided the heat pumps are installed by LG-trained professionals.
LG heat pump prices
LG's most popular heat pumps range from 5kW to 16kW and cost between £3,340 and £6,400.
The company offers a range of air source heat pumps under its THERMA V product line, providing efficient heating solutions for various home sizes. Here's a table summarising the key models and their approximate prices:
| Model | Capacity | Unit price |
|---|---|---|
| THERMA V R32 Monobloc S 5kW | 5 kW | £3,340-£4,000 |
| THERMA V R32 Monobloc S 7kW | 7 kW | £4,000-£4,500 |
| THERMA V R32 Monobloc S 9kW | 9 kW | £4,600-£4,900 |
| THERMA V R32 Monobloc S 12kW | 12 kW | £5,230-£5,700 |
| THERMA V R32 Monobloc S 16kW | 16 kW | £5,550-£6,400 |
It's important to note that these LG heat pump prices are approximate and can vary based on factors such as specific model features, supplier, and installation complexity.
Regarding savings and return on investment (ROI), heat pumps can offer significant long-term benefits. On average, households can expect to save up to £430 per year on energy bills when switching from an old G-rated gas boiler to a heat pump, with even greater savings possible when replacing oil or LPG systems.
The exact ROI depends on various factors, including your current heating system, energy prices, and home insulation.
To help offset the initial costs, the UK government offers grants through the Boiler Upgrade Scheme. Eligible households can receive up to £7,500 towards the cost of an air source heat pump installation.
With the £7,500 grant, an air source heat pump could break even in approximately 7-12 years based on average annual savings. Without the grant, the break-even point would be longer, potentially 10-15 years or more.
This grant significantly reduces the upfront investment, making heat pumps more accessible to a wider range of homeowners and potentially shortening the payback period which is equivalent to buying a new gas boiler.
