Case Study: LG 2.5kW Air Conditioning Installation for an Office in North Wales

Introduction

At Goodwin Electrical & Solar, we specialise in efficient air conditioning North Wales installations that deliver year-round comfort with extremely low running costs. In this project, we replaced old electric panel heaters with a modern LG 2.5kW split air-to-air heat pump featuring WiFi control and a handheld remote.

Client Background

The client’s office in North Wales was previously relying on basic electric heaters, which were:

Very expensive to run throughout the working day.
Slow to heat the room evenly.
Lacking any proper control or scheduling.

They requested a system that would:

Provide consistent, comfortable heating all day long.
Use far less electricity than electric heaters.
Offer WiFi/app-based control.
Provide cooling capability for summer months.

Our Air Conditioning Solution

Following our site survey, we recommended the LG 2.5kW air-to-air heat pump — an excellent choice for small offices, garden rooms and home workspaces across North Wales.

Indoor wall-mounted unit providing smooth and even heated airflow.
Outdoor condenser installed with anti-vibration feet.
WiFi connectivity via the LG ThinQ app.
Inverter-driven heating for maximum efficiency.

Why a Heat Pump Is Better Than Electric Heaters

Standard electric heaters work on a 1:1 ratio: 1kW electricity → 1kW of heat.

The LG heat pump delivers:
3–4kW of heat for every 1kW of electricity used (COP 3–4).

Up to 75% cheaper heating bills.
Much more stable room temperatures.
Far less wasted energy.

Running Cost: Full-Day Heating for Under £1

Once the office is warm, the heat pump modulates down to a low power draw (typically 0.25–0.35kW). Based on a standard workday:

0.30kW × 9 hours = 2.7kWh
2.7kWh × 30p ≈ £0.81 per day

The entire office is comfortably heated all day for less than £1 — even without solar contribution.

Comfort & Control Improvements

Even, comfortable heat across the workspace.
Fast warm-up first thing in the morning.
Remote scheduling and app control.
Cooling available during summer months.

Installation Process

Core drilling & insulated pipework installation.
Pressure testing and deep vacuum process.
Full commissioning & performance checks.
Setup of LG ThinQ WiFi app for the client.

Client Results

Significant reduction in heating costs.
Consistent room temperature throughout the day.
Quieter, cleaner and more efficient than panel heaters.
Year-round performance: heating & cooling.
