IVT Greenline - the UK's most popular Ground Source Heat Pump

With heating oil prices increasing, and Government support at it's highest ever level, demand for Ground Source Heat Pumps is set to increase through this heating season and into 2018. Alto Energy is the UK's exclusive distributor for IVT Ground Source Heat Pumps, the most popular Ground Source Heat Pump in the UK market.


Expensive Heating Oil & LPG



Fossil fuel prices have been much lower in recent years compared to the heights that were seen around 2010.

However, recent trends have shown that the price of heating oil has been increasing over the past two years, with the threshold of £500 per 1000 litres not far off being broken.

LPG is priced even higher at around £580 per 1000 litres.

Heat pumps operate using electricity, however for each unit of electricity consumed, over 3 units of heat are delivered. This is possible due to the fact that heat energy is simply being moved from one place (the ground) to another (the home). This is far more efficient than creating heat energy, which is what happens in a traditional combustion boiler. In this case, only 0.75 units of heat are delivered for each unit of fuel consumed.

At these prices, the cost per unit of heat delivered is significantly lower for Ground Source Heat Pumps compared to fossil fuels, as demonstrated in the graph below. This shows that Ground Source Heating is 44% cheaper than Heating Oil, and 68% cheaper than LPG heating.







Renewable Heat Incentive

The Domestic Renewable Heat Incentive ("RHI") is a government financial incentive to encourage a switch to renewable heating systems. If you join and comply with the scheme rules, you’ll receive quarterly payments for seven years. It’s a way to help the UK reduce its carbon emissions.

The current tariff for Ground Source Heat Pumps is 19.86p for each unit of renewable heat created by the heat pump. 

Below is an example for a typical 4-bedroom detached property with a heat load of 20,000 kWh. 

RHI Example

Annual RHI = £2,780

Annual Fuel Saving (vs. Oil) = £580

Total Annual Saving = £3,360

7-YEAR SAVING = £23,520
