Air Source Heat Pump Installation in Narberth, Pembrokeshire

Smart Energy Homes recently completed an air source heat pump installation at a four-bedroom bungalow in Narberth, Pembrokeshire, helping the homeowner transition away from oil heating and towards a more efficient, renewable heating solution.

As heating costs continue to fluctuate, many homeowners are reassessing traditional heating systems and exploring alternatives that offer greater long-term efficiency. In this case, the homeowner’s existing oil heating system was still operational, but their oil tank required replacement. Rather than investing in a new tank and continuing to rely on delivered fuel, they wanted to explore whether an air source heat pump could provide a more cost-effective solution for the future.

Understanding the Property

The property is a four-bedroom bungalow located near Narberth in Pembrokeshire. Built between 1920 and 1939, the home was heated by an oil boiler and already benefited from cavity wall and loft insulation. The homeowner was facing the cost of replacing an ageing oil tank and wanted to explore whether an air source heat pump could provide a more cost-effective and future-ready heating solution.

To determine whether a heat pump would be suitable, our team carried out a full property survey, assessing the insulation levels, heating requirements, existing pipework and radiator system. Following this assessment, we recommended a Grant Aerona 290 6.5kW Air Source Heat Pump as the most appropriate solution for the property.

Radiator Upgrades

An important part of many heat pump installations involves ensuring the property’s radiators are correctly sized to work efficiently with lower flow temperatures.

As part of this project, Smart Energy Homes upgraded four radiators using Stelrad Halcyon models:

Bathroom: Stelrad Halcyon 600×600 K2
Bedroom 1: Stelrad Halcyon 600×600 K1
Bedroom 3: Stelrad Halcyon 600×700 K1
Office: Stelrad Halcyon 600×700 K1

These upgrades help the new heating system distribute warmth effectively throughout the property whilst maintaining comfort levels for the homeowner.

Removed and disconnected the existing heating equipment where required.
Installed the Grant Aerona 290 outdoor unit.
Fitted the new hot water cylinder.
Upgraded key radiators.
Installed and commissioned the Grant smart controls.
Tested and optimised the heating system for maximum efficiency.
