Heating System Upgrades & System Conversions

An ageing or inefficient heating system costs more to run, is less reliable, and may no longer be able to adequately heat your property. Whether you need a straightforward boiler replacement, a full heating system upgrade, or a conversion from an old gravity-fed open-vented system to a modern sealed pressurised system, Sherborne Utilities has the expertise to deliver.

We carry out heating system upgrades and conversions for domestic and commercial clients across Dorset, Somerset, Wiltshire, Hampshire and Devon. Our heating engineers are experienced across all types of central heating system and can advise on the most appropriate and cost-effective upgrade or conversion for your property.

System conversions — for example, converting from an older open-vented gravity hot water and heating system to a modern sealed pressurised system — can significantly improve the efficiency and reliability of your heating, as well as enabling the installation of a higher-efficiency boiler and modern programmable controls.

All works are carried out by Gas Safe registered engineers where gas appliances are involved. We can also advise on and install ancillary heating improvements including zone controls, smart thermostats, magnetic system filters and inhibitor treatments to protect your investment.

Why Upgrade Your Heating System?

Modern heating systems deliver real benefits in efficiency, reliability and comfort.

Energy Efficiency

Modern heating systems operate at significantly higher efficiencies than older systems, reducing energy consumption and lowering heating bills.

System Upgrades

From upgrading an inefficient old boiler to full heating system refurbishment including radiators, pipework and controls — we deliver comprehensive upgrades.

All System Types

We work with all heating system types including open vented gravity systems, sealed pressurised systems, underfloor heating and combination boiler installations.

Domestic & Commercial

Our heating engineers handle heating system upgrades and conversions for both domestic and commercial properties across the South West.

Our Heating Upgrade Process

A professional approach from initial assessment through to commissioning and handover.

01

System Assessment

We survey the existing heating system, assess its condition and performance, review the heat load of the property, and identify the most appropriate upgrade or conversion option.

02

Specification & Quote

We provide a detailed specification for the proposed works and a clear, itemised quotation — so you know exactly what is included and what the project will cost.

03

Installation

Works are carried out by our experienced heating engineers. We manage the installation efficiently, minimising the period during which the heating system is unavailable.

04

Commissioning & Handover

The completed heating system is commissioned, balanced and tested before handover. We provide full instructions on operating the new system and its controls.
