As spring arrives across the West Midlands and Staffordshire, many homeowners in Tamworth, Sutton Coldfield, and Lichfield are thinking about reducing their energy bills after a long winter. Whether your heating system has been working overtime or you’re simply looking to cut costs ahead of next winter, now is the perfect time to review your home’s heating efficiency.
At Vulcan Heat, we’re Gas Safe registered (number 617816) and have helped hundreds of local homeowners get more from their heating systems. In this guide, we share practical, expert-backed advice to help you save money and stay comfortable all year round.
Why Heating Efficiency Matters Right Now
Energy bills remain a significant concern for UK households. The good news is that many of the most effective efficiency improvements are straightforward and affordable. From adjusting your boiler settings to installing smart controls, small changes can add up to hundreds of pounds in annual savings.
1. Start With Your Boiler: Servicing and Settings
Your boiler is the heart of your heating system, and keeping it in peak condition is the single most impactful thing you can do for efficiency.
Book an Annual Boiler Service
An annual service by a Gas Safe registered engineer ensures your boiler is running as efficiently as possible. During a service, the engineer will clean key components, check for wear and tear, verify the flue is safe, and confirm the system is operating at the correct pressure. A well-serviced boiler uses less gas to produce the same amount of heat — meaning lower bills and a longer lifespan for your appliance.
Skipping a service can also invalidate your boiler’s manufacturer warranty, leaving you exposed to the full cost of any repairs. If you haven’t had your boiler serviced recently, book a boiler service with Vulcan Heat today.
Lower Your Boiler’s Flow Temperature
Many homeowners don’t realise that their boiler’s flow temperature — the temperature at which water is sent to the radiators — can be adjusted for greater efficiency. Modern condensing boilers are designed to operate most efficiently at lower flow temperatures (around 55–60°C). At these temperatures, the boiler enters “condensing mode,” recovering heat from exhaust gases that would otherwise be wasted.
Lowering your flow temperature won’t make your home colder; it simply means the boiler runs for slightly longer at a lower intensity, which is far more efficient. Ask your engineer to check and optimise this setting during your next service.
Monitor Your Boiler Pressure
Incorrect boiler pressure is a common cause of inefficiency and breakdowns. Most boilers operate best between 1 and 1.5 bar. If the pressure is too low, the system won’t heat effectively; too high, and it can strain components. Check your boiler’s pressure gauge regularly and consult your manual if you need to repressurise. If you’re unsure, our engineers are happy to help — contact Vulcan Heat for advice.
2. Upgrade to Smart Heating Controls
Smart thermostats are one of the most popular and effective upgrades for homeowners in Sutton Coldfield, Tamworth, and Lichfield. Devices like Google Nest and Hive learn your routine, use geofencing to detect when you’re home, and allow you to control your heating remotely via a smartphone app.
Based on current energy tariffs, a smart thermostat can deliver savings of £150 to £300 per year on heating bills, with a typical payback period of just 12–18 months. Key features to look for include:
- Auto-learning schedules — the thermostat adapts to your lifestyle automatically
- Geofencing — heating switches off when you leave and comes back on as you return
- OpenTherm compatibility — allows the thermostat to communicate directly with your boiler for optimised efficiency
- Multi-zone control — set different temperatures in different rooms
From April 2026, new regulations also require heating controls to meet minimum efficiency standards, so if your controls are older, now is a great time to upgrade.
3. Install Thermostatic Radiator Valves (TRVs)
Thermostatic Radiator Valves (TRVs) are a simple, cost-effective way to control the temperature in individual rooms. Rather than heating your entire home to the same temperature, TRVs allow you to turn down the heat in rooms you’re not using — such as spare bedrooms or a home office when you’re not working.
Research shows that correctly installed and used TRVs can reduce heating energy use by an average of 18%, saving a typical household around £110 per year.
A few important tips for TRVs:
- Don’t fit a TRV on the radiator in the same room as your main thermostat. The two controls can conflict, causing your boiler to run inefficiently.
- Keep the radiator in the thermostat room fully open and let the wall thermostat control that zone.
- TRVs are most cost-effective when fitted during a boiler replacement, when the system is already drained.
If you’re having a new boiler installed in Lichfield, Tamworth, or Sutton Coldfield, current regulations in England require thermostatic room controls to be fitted at the same time — TRVs are the most common way to comply.
4. Draught-Proof Your Home
Even the most efficient boiler will struggle if your home is losing heat through gaps and draughts. On average, 25% of a home’s heat is lost through unwanted draughts — a significant and often overlooked source of energy waste.
Common draught sources include:
- Gaps around windows and doors
- Letterboxes and keyholes
- Gaps between floorboards and skirting boards
- Unused chimneys
- Loft hatches
Sealing these gaps is one of the most cost-effective improvements you can make. DIY draught-proofing materials are inexpensive, and professional whole-house draught-proofing typically costs around £250. The potential savings are impressive:
- Comprehensive draught-proofing: up to £85 per year
- Blocking an unused chimney: up to £60 per year
One important note: don’t block intentional ventilation points such as extractor fans, airbricks, trickle vents, or wall vents. These are essential for air quality and preventing damp.
5. Common Mistakes That Waste Energy
Many homeowners in the West Midlands unknowingly make simple mistakes that reduce their heating system’s efficiency. Here are the most common ones to avoid:
Cranking Up the Thermostat
Setting your thermostat to a very high temperature doesn’t heat your home faster — it just makes your boiler work harder for longer. Set it to your desired temperature (18–20°C is comfortable for most people) and let the system do its job.
Blocking Radiators
Placing sofas, curtains, or large furniture in front of radiators traps heat and prevents it from circulating around the room. Keep the area around your radiators clear for effective heat distribution.
Heating Empty Rooms
If you’re not using a room, there’s no need to heat it. Use your TRVs to turn down the heat in unoccupied spaces and keep the doors closed to retain warmth in the rooms you are using.
Neglecting Insulation
A well-heated home with poor insulation is like trying to fill a leaky bucket. Prioritise loft insulation, cavity wall insulation, and draught-proofing to keep the warmth inside where it belongs.
6. Government Schemes Worth Knowing About
If you’re considering a larger upgrade, there are government schemes that may help with the cost:
- Boiler Upgrade Scheme (BUS): Offers grants of up to £7,500 for homeowners in England and Wales switching to low-carbon heating such as heat pumps. From April 28, 2026, the grant must be shown as an upfront discount on installer quotes, and air-to-air heat pumps are now eligible for a £2,500 grant.
- ECO4: Provided grants for energy efficiency upgrades to low-income households. The scheme ended March 31, 2026, but a successor “Warm Homes Plan” is expected to follow.
