Radiator Upgrade Project

Old Radiators Out. New Stelrad Halcyon Radiators In.

This recent radiator upgrade came via a personal recommendation from one of our existing customers. The client wanted to replace ageing radiators that were beginning to suffer from degraded performance and modernise the heating system throughout the property before winter.

A Wise Investment In A Pre-1900s Property

The existing radiators had been in place for many years and were no longer performing as they once had. Our customer wanted a reliable long-term upgrade that would improve heat output throughout the house and give every room a cleaner, more modern finish.

We chose Stelrad Halcyon radiators throughout the property, with each radiator backed by a 15-year manufacturer warranty. New thermostatic radiator valves were also installed on each radiator to provide improved individual room temperature control.

Although radiator replacement can sometimes appear straightforward, this particular project came with the sort of challenges often found in much older homes.

Project Overview

Property Traditional Pre-1900s Home
Radiators Stelrad Halcyon
Controls New Thermostatic Radiator Valves
Warranty 15 Years Per Radiator
Duration Approximately A Day And A Half

Not A Straightforward Radiator Swap

The old heating system featured rigid pipework and poor underfloor access, so much of the upgrading had to be carried out above floor level. That meant working carefully with the existing pipe runs while still achieving a neat finished installation.

Being a pre-1900s property also meant the walls had seen plenty of work over the years. Catching secure fixings into old lath and plaster added another layer of difficulty, but careful planning allowed us to complete the upgrade without unnecessary disruption.

BEFORE / AFTER
Before Old radiator before replacement in traditional property
After New Stelrad radiator after replacement in traditional property

Before

The existing radiator was showing its age and no longer matched the level of performance the customer wanted from the heating system.

After

The modern replacement gives the room a cleaner finish and significantly improves the heating system's capability through winter.

Radiator Upgrade 08

BEFORE / AFTER
Before Old radiator before final replacement
After New Stelrad radiator after final replacement

Before

Another ageing unit forming part of the full-property radiator replacement programme.

After

A new Stelrad Halcyon radiator completes the transformation with a tidy installation and modern thermostatic control.

The Challenges

Working Carefully In An Older Home

Older properties often require a very different approach to heating upgrades, especially when the original building fabric and pipework have been in place for decades.

01

Rigid Old Pipework

The existing heating pipework offered very little flexibility, so careful adaptation was required to connect modern radiator sizes cleanly.

02

Poor Underfloor Access

Limited access beneath the floors meant much of the upgrading had to be completed above floor level rather than relying on hidden alterations.

03

Lath & Plaster Walls

Securely fixing modern radiators to traditional lath and plaster requires patience and careful positioning to achieve a solid installation without unnecessary damage.

15

Year Warranty Per Radiator

The Stelrad Halcyon radiators installed on this project come with a 15-year manufacturer's warranty, giving the customer long-term peace of mind alongside improved heat output and a much cleaner finish throughout the property.

Additional Installation

One Final New Radiator

This final radiator did not have a matching before photograph, so it is shown separately from the paired transformations above.

A Consistent Finish Throughout The Property

The additional installation follows the same specification as the rest of the property, giving the customer consistent radiator performance and a uniform finish across the heating system.

A Day And A Half Well Spent

This was a good day and a half of work for us, with plenty of small challenges along the way, but the end result was exactly what the customer wanted. The house now has brand-new radiators throughout, improved thermostatic control and significantly better heating performance ready for winter.

For an older property where the radiators had begun to degrade in both appearance and performance, this really was a wise investment.
