Preparing Your Boiler for Autumn: Do These Now

Simple Checks Now = No Nasty Surprises When the Cold Hits

Autumn might feel like a distant thought while the last of the summer sun hangs on - but now is the perfect time to get your boiler in shape for the colder months.

At Wells Spa, we always see the same pattern: the first chilly morning hits, everyone switches on their heating for the first time in months… and suddenly, we’re flooded with emergency call-outs.

Don’t let your boiler catch you off guard. A bit of prep now can save you stress, money and a freezing cold house later.

Why Autumn Boiler Prep Matters

Boilers are like any hardworking system - they need a little attention to keep running smoothly. After months of lying dormant, it’s common for issues to crop up. Think seized pumps, low pressure, cold radiators, or strange noises. Left unchecked, these can escalate into full breakdowns just when you need heating most.

The good news? Most of these problems are easily avoided with a few quick actions before the real cold sets in.

1. Book Your Boiler Service Early

   Don’t wait for the rush. Autumn is the best time to book your annual boiler service.

A professional Gas Safe engineer (like one of ours) will:

• Check key components for wear and tear

• Test safety controls and carbon monoxide output

• Clean out any build-up of debris or sludge

• Identify potential issues before they become problems

It’s the easiest way to ensure your boiler is safe, efficient and ready to deliver consistent heating all winter long.

Pro tip: Booking early means you’re more likely to get a time that suits you and avoid the pre-winter scramble.

2. Bleed Your Radiators

   If your radiators feel warm at the bottom but cold at the top, they’re likely holding trapped air and that means your heating system is working harder (and costing more) than it should.

Bleeding your radiators:

• Releases trapped air

• Improves heating efficiency

• Reduces strain on your boiler

All you need is a radiator key, a cloth and a few minutes per radiator.

3. Check Your Boiler Pressure

   Your boiler works best when the pressure sits in the “Goldilocks zone”, usually between 1 and 1.5 bar.

Too low? Your boiler may struggle to fire up.

Too high? It could lead to leaks or system strain.

You’ll find the pressure gauge on the front of your boiler. If it’s not in the right range, check your user manual or give us a call - we’re happy to help.

Bonus Tip: Test Your Thermostat

If you’ve got a programmable thermostat or smart heating controls, autumn is the perfect time to update your schedule. Set it to match your new routine as the days get shorter and the evenings cooler.

Avoid Early Cold Weather Failures

Boiler breakdowns don’t just happen in January - they start with missed servicing, clogged radiators and unnoticed pressure drops in autumn.

By tackling these simple tasks now, you’ll:

• Keep your heating system efficient

• Reduce your energy bills

• Avoid costly emergency repairs

• Stay warm from the moment you need it
