When might you need a new heating system?

There are several signs that may indicate that it’s time to upgrade to a new heating system. If your current system is over 15 years old and requires frequent repairs, or if it is no longer able to keep your home warm and comfortable, it may be time for a replacement. 

Sludge, limescale, and rust can build up in your pipes which can limit the efficiency of your heating system and whilst on some occasions, a power flush could fix this, there comes a point where the damage may be too extensive. 

If you discover a leak in your heating system, these tend to be fixable but, again, with an older system, it might be better to consider making the switch to a newer model.

You may also want to consider a new heating system if you’ve recently expanded your home or if you’re looking to improve energy efficiency and reduce your heating bills. If you are unsure whether your heating system needs an upgrade, contact a heating professional who can assess your current system and help you determine if it’s time for an upgrade.

Pros of installing a new heating system

1. Improved energy efficiency

One of the biggest advantages of a new heating system is improved energy efficiency. Newer systems are designed to operate more efficiently, meaning they can heat your home using less fuel or electricity. As a result of reducing an old system, you could benefit from a reduced carbon footprint, and even lower heating bills!

2. Consistent comfort

As new systems are better equipped to distribute heat evenly, you are likely to have fewer hot and cold spots resulting in a more consistent level of heating and making a more comfortable environment for you and your family. 

3. Increased home value

Upgrading to a new heating system can also increase the value of your home. If you’re planning to sell your home in the future, a new heating system can be a major selling point as well as making it more attractive to potential renters if you’re planning to rent it out.

4. Better air quality

Replacing a central heating system can help to improve the air quality in your home. Older systems may circulate dust, mould, and other allergens, while newer systems are better equipped to filter these particles out of the air. This can be especially beneficial if you or anyone in your family suffers from allergies or respiratory issues.

5. Reduced maintenance

New heating systems tend to require less maintenance than an older system. With regular tune-ups and maintenance, a new system can run smoothly for many years, which means fewer repair costs and less hassle for you.

Cons to installing a new heating system

1. Upfront cost

One of the main disadvantages of installing a new heating system is the upfront cost. New systems can be expensive, especially if you’re upgrading to a high-efficiency system, however this can be offset by the long-term savings on energy bills and potential increase in home value. Bear in mind that you could be entitled to support in the form of a grant

2. Disruption during installation

Depending on the type of system you choose, installation can be disruptive to your home life. For example, if you’re installing a new boiler, you may need to temporarily shut off your water and heating supply, which can be inconvenient, however, a professional installation team can work with you to minimise disruption.

3. Compatibility with existing infrastructure

Installing a new heating system may require updates to your existing infrastructure, such as ventilation, gas lines, or electrical systems. If your home is older, this may require additional work and expense, which should be factored into the overall budget.

4. Maintenance requirements

While a new heating system may require less maintenance than an older system, it will still require some maintenance to keep it running smoothly. This includes regular servicing and filter replacements. While these costs are typically minimal, they should still be factored into your decision.

5. Technology changes

With the constant changes in technology, a new heating system may become outdated in a relatively short period of time which may result in you needing to upgrade again sooner than you would like, at further expense. To reduce this risk, you will want to invest in a high-quality system with a good warranty.

Frequently Asked Questions

Should I replace my radiators when upgrading my heating system?

If you’ve bought a new heating system, it would make sense to think about changing the radiators at the same time as it would reduce further disruption at a later date and can also lower the cost, as it is easier to do both at the same time. 

How long does it take to fit a new heating system?

For an entire new central heating system, it could take between 1-2 weeks for the installation to be completed, as it will often involve flooring to be lifted, as well as laying pipework. If you are having radiators installed at the same time, then this will prolong the completion time. 

How much does a new boiler cost?

The cost of a new boiler usually sits anywhere “between £1000-£3000”. Sometimes with a conventional boiler it can push all the way up to £4500. 

How messy is installing central heating?

Installing a new heating system can be disruptive as you will often find that carpets or laminate need to be lifted, especially if you have any underfloor heating. There could also be a need for some holes in walls or ceilings to be made, so it is best to expect a high level of mess. 

Conclusion

Installing a new heating system into your home offers many benefits including improved energy efficiency, a reduced need for maintenance, and it can even increase the value of your property. 

There are however, a number of disadvantages too from the disruption that comes from the installation process to potential changes to your existing infrastructure. 

You will want to take into account the age of your current system and budget, amongst other factors, before you make a final decision on whether it is time to upgrade your central heating. 

Seeking guidance from a heating professional can help you make an informed decision and ensure that your new heating system meets your needs as well as providing long-term benefits for your home.
