A heating system is one of the most important parts of your home. It keeps you warm, protects your plumbing, and helps manage energy use. Whether you’re fitting a new boiler or maintaining an older unit, understanding the full life cycle of your heating system enables you to plan for costs and efficiency. G&M Plumbing and Heating LTD provides the heating supplies and expert support you need at every stage.

Installation: Getting It Right From the Start
A heating system usually begins with professional installation. Choosing the right size and type of system matters. Too small and it struggles to heat your home; too large and it wastes fuel. A qualified engineer will assess your property size, water demand, and existing pipework before installation.
During installation, it’s also worth investing in high-quality fittings and controls. Smart thermostats and magnetic filters can improve efficiency and extend lifespan.
Operation: How Long Does a Heating System Last
A typical gas boiler lasts around 10 to 15 years: the exact lifespan depends on the build quality, water hardness, and the frequency of service. Modern condensing boilers are more efficient, but they require regular maintenance to maintain that efficiency over time. Having regular checks of pressure levels, filters, and radiators help prevent future breakdowns and ensure optimal performance.
Simple steps can make a difference:
- Bleed your radiators each year.
- Check boiler pressure monthly.
- Watch for leaks or changes in heating performance.
Maintenance: Keeping It Efficient
An annual service is the most effective way to maintain your system. Engineers check for corrosion, clean components, and test safety systems. Routine maintenance also reduces energy costs by keeping the system running smoothly.
At around the 7 to 10-year mark, parts such as pumps, fans, and diverter valves may need replacing. These components wear out over time, affecting efficiency. G&M Plumbing and Heating LTD stocks genuine replacement parts and heating accessories to keep your system performing at its best.
Replacement: Knowing When It’s Time
Even with care, every heating system reaches a point where repair becomes uneconomical. Frequent callouts, unusual noises, or rising bills are common signs that it’s time to upgrade. Modern A-rated boilers can save up to 20% on energy use compared to older models.
