Thanks to energy savings and financial incentive, this 8.5kW Mitsubishi Ecodan system provides the customer with a 6-year return on investment.

An 8.5kW Mitsubishi Ecodan air source heat pump.

The 8.5kW Ecodan unit replaced an oil boiler and now covers 100% of the home’s heating and hot water demand. All-in-all, the customer’s switch from oil to renewables sees them reduce their energy bills and carbon output.

Ins and outs of this 8.5kW Mitsubishi Ecodan

The customer chose air source heating as a way to lower their heating cost and make their home more comfortable and self-controlled. Air source heating removed the need for oil deliveries. In addition, technology within the heat pump self-controls heat provision.

This air source heat pump system consists of the following:

– 1 x 8.5kW Mitsubishi Ecodan air source heat pump
– 1 x 250-litre hot water tank

GreenGenUK were responsible for:

– Install, mount and enclose the air source unit
– Install hot water tank and radiators
– Install of electrical system
– Commission and certificate the system

GreenGenUK employs plumbers and electricians. As such, we’re able to handle all aspects of the project. Furthermore, we handled the upgrades to the customer’s central heating system. As a heat pump generates heat at lower flow rates, it’s often required to upsize some of the property’s radiators. Doing so enhances the efficiency of the heat pump and further reduces running costs.

System Benefits

Switching heat demand to air source provides the customer with the following benefits:

– Energy Savings

Air source heat pumps replace grid demand with free energy from the air. As a result, customers will see their bills cut.

GreenGenUK predicts this heat pump will reduce the customer’s bills by £500 a year.

– Renewable Heat Incentive

In order to meet carbon targets, the government started the Renewable Heat Incentive scheme to encourage customers to switch to a renewable heating system and, as a result, lower their carbon footprint.

The RHI scheme pays anybody who has switched to a renewable technology for the heat their system generates. A deemed tariff, domestic customers installing through an MCS installer earn payment for 7 years.

In total, this customer will earn £4850 from the RHI scheme.

– Carbon Reduction

In addition to creating energy saving, swapping energy demand from harmful fossil fuels also has a positive impact on carbon output. Swapping to a renewable heating solution reduces the amount of carbon dioxide a home produces.

This 8.5kW Ecodan install creates an annual carbon reduction of 4.37 tonnes.

Payback Period

One of the key selling points of a renewable heating solutions is their ability to repay themselves. The combination of energy savings and RHI payment means most installations repay themselves within  7-years.

Overall, this customer’s 8.5kW Mitsubishi Ecodan heat pump will see a return on investment within 6 years.

Enclosing of the Heat Pump

The customer tasked GreenGenUK with providing an enclosure for the heat pump unit.

Enclosing the heat pump provides the customer with several benefits. Firstly, the heat pump is protected from accidental damage. This helps maintain performance and warranty. Secondly, casing this air source unit reduces the visual impact of the installation. By keeping the enclosure in keeping with the style of the building, the property’s feel is sustained and the heat pump hidden.

Enclosing an air source heat pump can impact its efficiency when not done correctly. Heat pumps need clean air flow to work efficiently. As a result, the pumps need space both behind and infront of the unit. All customer’s considering enclosing their heat pump must consider this.
