Simple Heating Upgrades That Could Improve Energy Efficiency

Last updated: November 2026

With energy costs remaining an important consideration for many households, it’s understandable to want your heating system to work as efficiently as possible.

But improving your home's heating efficiency doesn't necessarily mean replacing your entire central heating system.

From better heating controls and thermostatic radiator valves to regular boiler servicing, there are a number of relatively simple improvements that could help you take greater control of your heating and reduce unnecessary energy use.

That's worth considering when heating and hot water account for over half of a typical home's energy use. Energy Saving Trust

At APV Heating Services, we help homeowners across Tunbridge Wells, Pembury and the surrounding areas maintain and improve their heating systems. Here are some of the upgrades worth considering if you'd like your home heating to work smarter.

1. Upgrade Your Heating Controls

One of the first places to look is how you actually control your heating.

Older systems may rely on fairly basic timers and thermostats. Modern heating controls can give you much greater control over when your heating operates and how warm your home becomes, helping you avoid heating your home unnecessarily.

The Energy Saving Trust recommends that boiler-based central heating systems should generally have a programmer or time control, at least one room thermostat and thermostatic radiator valves. Energy Saving Trust

Could a smart thermostat help?

Smart heating controls can add another level of convenience.

Depending on the system, they can allow you to adjust your heating remotely using an app, create schedules around your routine and, in some cases, use features such as geofencing or learning your heating habits.

However, a smart thermostat isn't automatically the best choice for every household. How much difference it makes depends partly on your existing heating controls and how you currently use them.

A good heating engineer can advise whether upgrading your controls would provide a worthwhile improvement for your particular system.

2. Fit or Upgrade Thermostatic Radiator Valves

Not every room in your home needs to be heated to exactly the same temperature.

Thermostatic radiator valves (TRVs) allow you to control individual radiators, so you can keep frequently used rooms comfortable while setting lower temperatures in rooms that need less heat.

TRVs work by regulating the flow of hot water through the radiator according to the surrounding temperature. As the room warms, the valve reduces the flow of hot water.

Used correctly, that means you're not unnecessarily heating every room to the same level.

According to the Energy Saving Trust, installing and effectively using a programmer, room thermostat and thermostatic radiator valves could save a typical household around £100 a year in Great Britain, although actual savings will depend on the property, existing controls and how the heating is used.

3. Make Sure Your Radiators Are Working Effectively

Sometimes improving heating efficiency isn't about adding new technology at all.

If a radiator is cold at the top, it may contain trapped air and need bleeding. If it has persistent cold areas – particularly towards the bottom – there may be another issue within the system that needs investigating.

Radiators also need space to distribute heat effectively. Large furniture positioned directly in front of them can restrict the movement of warm air around the room.

If some rooms are noticeably warmer than others, the heating system may also benefit from being checked and correctly balanced so heat is distributed more effectively around the property.

4. Have Your Boiler Serviced Regularly

A heating system can only perform well if the boiler at the centre of it is properly maintained.

An annual boiler service gives a qualified engineer an opportunity to check the boiler's condition, safety and performance and identify signs of wear or developing problems.

It would be misleading to suggest that simply having a service will automatically reduce your energy bills. However, regular servicing helps ensure that your boiler is being professionally checked and operating as it should.

APV Heating Services is Gas Safe registered and provides annual boiler servicing across Tunbridge Wells, Pembury and the surrounding areas.

5. Consider Whether Your Existing Boiler Is Still the Right Solution

Sometimes small improvements are enough. But there comes a point when continuing to invest in an ageing, inefficient or unreliable boiler may no longer be the best option.

Modern condensing boilers are designed to recover more useful heat from their exhaust gases than older non-condensing models.

That doesn't mean you should replace a perfectly good boiler simply for the sake of having a newer one. The age and condition of your existing boiler, your property's heating requirements, repair history and budget should all form part of the decision.

If your boiler is frequently breaking down, struggling to heat your home or becoming increasingly expensive to repair, APV can assess the system and advise whether repair or replacement makes more sense.

APV installs Vaillant, Ideal and Worcester Bosch boilers, helping homeowners select an appropriate boiler for their property rather than simply recommending a one-size-fits-all solution.

6. Don't Overlook the Wider Heating System

The boiler is only one part of your central heating.

Radiators, pipework, pumps, valves and controls all affect how effectively heat reaches the rooms in your home.

If your boiler appears to be working but certain radiators take a long time to warm up, rooms heat unevenly or the system isn't performing as it once did, it's worth having the whole heating system assessed rather than assuming the boiler itself is the problem.

Depending on the cause, the solution might involve balancing radiators, replacing an ineffective component, improving controls or carrying out other appropriate system maintenance.

This is where advice from an experienced heating engineer matters: the most expensive upgrade isn't necessarily the right upgrade.

7. Could a Heat Pump Be Right for Your Home?

For homeowners considering a more significant change, a heat pump offers an alternative approach to heating a property.

Rather than generating heat by burning fuel, a heat pump transfers heat from the surrounding environment into the home. The suitability and performance of a heat pump depend on factors including the property itself, its heat loss, radiators or other heat emitters and how the system is designed.

So this isn't really a "quick upgrade" in the same category as installing TRVs or improving heating controls – but it is worth considering when thinking about the longer-term energy efficiency of your home.

APV can install heat pumps as well as conventional boiler-based heating systems, allowing the team to advise homeowners on the options available rather than assuming one technology is suitable for every property.

The government's current Boiler Upgrade Scheme also provides grants towards eligible low-carbon heating installations, including £7,500 towards an air source or ground source heat pump. Eligibility and grant levels can change, so homeowners should check the current scheme before making a decision. GOV.UK

Which Heating Upgrade Should You Make First?

There isn't one answer that applies to every home.

For one household, adding better heating controls or TRVs may be the logical starting point. Another property may have an ageing boiler or an underlying central heating problem that needs attention first.

Before spending money, consider:

  • How old is your boiler?
  • When was it last serviced?
  • Can you control different areas of your home effectively?
  • Do all your radiators heat evenly?
  • Are you heating rooms when you don't need to?
  • Does your heating system regularly require repairs?
  • Are you planning other home improvements that could affect your future heating requirements?

An experienced heating engineer can assess the existing system and help identify which improvements are likely to be worthwhile.

Frequently Asked Questions About Energy-Efficient Heating

They can help reduce unnecessary energy use by giving you better control over when and how your home is heated. However, potential savings depend on your existing controls, your property and how you currently use your heating.

TRVs allow individual rooms to be controlled separately, which can help avoid unnecessarily heating rooms to the same temperature. They are one of the standard heating controls recommended by the Energy Saving Trust for boiler-based central heating systems. Energy Saving Trust

Not necessarily. If your existing boiler is operating reliably and efficiently, other improvements may be more appropriate. If it is old, unreliable or costly to repair, it's worth discussing whether replacement would make sense for your home.

A boiler service isn't a guarantee of lower energy bills. It does, however, allow a qualified engineer to check your boiler's safety, condition and performance and identify issues that may be affecting how it operates.

Heat pumps operate differently from boilers and can deliver several units of heat for each unit of electricity they consume. However, their real-world performance depends heavily on appropriate system design and the property they're installed in. A proper assessment is therefore important before deciding whether a heat pump is right for your home.
