Heating work that keeps your home running properly
Cold rooms, noisy radiators and patchy hot water can make your whole house feel like hard work. We handle heating jobs, from radiator fitting and thermostat installation to power flushing and heating repairs. Our engineers also work with combi, conventional and system boilers, as well as gravity-fed cylinders, unvented hot water cylinders, and solar hot water systems.
If parts of your heating system are not performing, we can identify the cause and recommend the most appropriate solution. We also undertake bathroom installation projects, helping homeowners improve comfort and functionality alongside their plumbing and heating systems. We carry out every job with the same practical mindset that has helped STH Plumbing & Heating Ltd build our reputation.

A better setup starts with the right system
When replacement equipment or a larger upgrade is required, STH Plumbing & Heating Ltd take the time to assess how your property uses heat and hot water before recommending a solution. Underfloor heating can provide a more even distribution of warmth while freeing up valuable wall space, and modern controls can offer greater flexibility over daily heating schedules.
As preferred installers of Vaillant systems, we can fit boilers backed by 7 or 10-year warranties where applicable. Being Gas Safe registered (539111) also means all gas heating work is completed safely and professionally.
Frequently asked questions
Why heating upgrades can make such a difference
A well-designed heating system helps create a more comfortable living environment throughout the property. Improved circulation, better temperature control and correctly sized components can all contribute to more consistent performance. Power flushing can help remove sludge and debris that restrict flow, while modern controls make it easier to adapt heating around changing routines. These improvements can help keep your home comfortable throughout the year and reduce many of the frustrations associated with ageing systems.
