Air Source Heat Pump Installation Near Gillingham, Dorset

High-Performance System for a Large Rural Property

This project near Gillingham involved the design and installation of a large-scale air source heat pump system for a substantial rural home, replacing an outdated boiler and hot water setup with a fully integrated, modern heating solution.

While this installation was completed prior to the recent grant increase, homeowners upgrading today can now benefit from the £9,000 government grant when switching from oil or LPG.

The Brief

The property required a robust, high-output heating system capable of:

• Heating a large home efficiently
• Supporting high hot water demand
• Integrating new radiators and underfloor heating
• Providing reliable, controllable heating across multiple zones

What We Did

This was a full plant room and system transformation, including:

• Removal of the existing boiler, flue, cylinder, and cold water storage tanks
• Full system powerflush and chemical clean to prepare existing pipework

We then installed a bespoke multi-unit heat pump system:

• 3x Daikin High Temperature Air Source Heat Pumps
• Buffer tank to optimise system performance
• Daikin unvented hot water cylinder for high demand hot water

To support the system, we installed:

• Multiple pumps, zone valves, magnetic filters, and strainers
• Pressurisation unit and expansion vessels
• Secondary hot water return system
• Full pipework insulation throughout

Heating Distribution Upgrades

To ensure the system worked efficiently across the whole property:

• Installed multiple new radiators throughout the home with TRVs
• Installed underfloor heating to a new extension
• Zoned the system using Smart Thermostats
• Set up full smart controls with internet access for remote management

Electrical & Plant Room Installation

A completely new plant room setup was created, including:

• New 3-phase electrical supply and consumer unit
• Dedicated circuits for heat pumps and all system components
• Full wiring of controls, sensors, pumps, and safety systems
• NICEIC certification and Part P compliance

The Result

The property now benefits from a fully integrated, high-capacity heating system designed for efficiency, control, and long-term reliability.

• Consistent heating across a large property
• Strong hot water performance for high demand households
• Zoned heating for improved comfort and efficiency
• Future-ready system with smart controls

£9,000 Government Grant – Now Available

At the time of this installation, the grant available was £7,500.

However, homeowners replacing oil or LPG systems can now receive £9,000 through the Boiler Upgrade Scheme (BUS)—making systems like this far more accessible.
