Air Source Heat Pump Installation

Replacing an oil boiler, this Air Source Heat Pump saved our customer £1,400 per annum in fuel costs.

Background

With energy prices continuing to surge in the cost of living crisis, this detached barn conversion had an annual fuel bill of £3,000, a carbon footprint of 7.8 tonnes of carbon dioxide per annum. Heated by an oil boiler with an unvented cylinder and underfloor heating, the owners approached NCS to enquire about the suitability of alternative heating solutions to assist in reducing their energy bills and minimising their carbon footprint. After an initial consultation, the property was deemed to be ideal for an Air Source Heat Pump (ASHP) integrated into their existing controls and heating system (particularly their underfloor heating, which is ideal for an ASHP) – a logical and extremely economical upgrade for their heating and hot water.

The Install

This property opted for a Grant HPID13R32 Quiet Mark R32 13kW Air Source Heat Pump and Installation Pack, which allowed for this integration, providing mains pressure hot
water and affordable heating. The key features of this ASHP included a Seasonal Coefficient of Performance (SCOP) of 4.11, or yearly efficiency of 411% for heating, and quiet operation with a sound pressure level at 1m dB rating of just 53, quieter than a conversation between two people sitting at a distance of one metre (60dB). The NCS team conveniently installed the pump onto the roof of the barn’s bike store to keep it out of useable space and discreetly hide it from view, blending it into the background of the shiplap boards of the barn with a wood effect vinyl wrap.

Thanks to the Boiler Upgrade Scheme, the owners were able to access a £5,000 government grant to reduce their installation costs. To be eligible for the Boiler Upgrade Scheme grant, you must:

own the property you’re applying for (including if it’s a business, a second home, or a property you rent out to tenants)
have installed (or plan to install) your new heating system on or after 1 April 2022
be replacing fossil fuel heating systems (such as oil, gas or electric)
have a valid Energy Performance Certificate (EPC) for your property, with no outstanding recommendations for loft or cavity wall insulation

The Outcome

After a successful installation of the new Air Source Heat Pump, the barn’s energy bill was nearly halved – with annual energy costs down to just £1,700 annually. Their heating system’s carbon output was reduced to just 3.2 tonnes per annum, a 59% decrease.
