Most boilers in Cardiff are running hotter than they need to.

There are two temperature dials on a combi. One is the hot water at your tap. The other, usually marked with a little radiator symbol, is the flow temperature, and most boilers are still sitting where they left the factory at 75 to 80 degrees.

Your boiler is a condensing boiler. It only hits the efficiency it was sold on when the water coming back from the radiators is cool enough for the flue gases to condense. At 80 degrees that never really happens.

Turn that radiator dial down to 60. Research puts it at around 9% off your gas use, and it costs you nothing.

Two honest caveats. The house will warm up a bit more slowly, so bring your timer forward half an hour. And if you have a hot water cylinder in the airing cupboard rather than a combi, leave it alone and ask me first, because that needs to run hotter to stay safe.

Another kind review in from Mark after his boiler service. Thanks Mark, much appreciated.

If yours hasn’t been serviced in the last 12 months, now’s a good time to sort it. Book online at boilercraft.co.uk or drop me a message.

A recent survey found a boiler service is one of the most put-off jobs in the house.

Fair enough, it never feels urgent in August. But September is when the diary fills up, and January is when the put-off jobs bite back.

A service takes about an hour, includes an ADEY test of your system water, and you get your certificate the same day.
Book yours before the autumn rush and it’s one less thing on the list.

Booking online takes about a minute:

Good luck to everyone picking up GCSE results this morning. And if you got A-level results last week, this one is for you too.

Here’s how mine went. GCSEs were alright. A-levels were a different story. I dropped out.

These days I run my own business, I love what I do and I make a good living doing it. Dropping out has never once held me back.

Results matter, but they don’t decide your life. There’s more than one route to work you’re proud of, and some of them start with a toolbox instead of a lecture hall.

Whatever your envelope said, you’ll be alright.

Just picked up the keys to a new home? One thing most people never check: the boiler.

Look for a service sticker or paperwork from the previous owner. No record of it ever being serviced? That’s worth sorting before winter. And if it’s a new build, most manufacturers require an annual service to keep the warranty valid.

Just moved to Cardiff or the Vale? Send me a message and I’ll take a look for you.

A minute of heating news, and what it means for your home.

1. An illegal gas fitter was sentenced last week. He advertised on Facebook and put the Gas Safe logo on his flyers, but was never registered. Before anyone touches your gas, check them at gassaferegister.co.uk. I’m on there, No. 964565, and always happy to show my ID card at the door.
2. Worcester Bosch just built its one millionth Greenstar 4000 boiler. It is a range I know inside out, and as a Worcester Bosch Accredited Installer I fit the 4000 with up to a 10 year warranty.
3. Energy bills look set to nudge up again in October. Nothing dramatic, but worth knowing: a well serviced boiler wastes less of the gas you pay for.

If anything here raises a question about your own boiler, send me a message. Happy to help.

Your boiler usually gives you a warning before it gives up.

Banging or whistling noises. Pressure that keeps dropping. Radiators warm at the top, cold at the bottom. Little things that turn into big things if they get ignored.

I’ve written a plain-English guide to the 8 boiler faults I see most across Cardiff and the Vale: what causes them, what a repair roughly costs, and which ones you can safely check yourself before picking up the phone.

Read it here: https://boilercraft.co.uk/portfolio/boiler-repair-cardiff-common-faults-costs/

And if your boiler is playing up right now, diagnosis is £90, and that comes off the repair cost if you go ahead. Gas Safe registered, 100+ five-star reviews.

New van racking in from Yoke Van Racking and I’m chuffed with it. Spent the weekend getting everything sorted, still a bit of fine tuning to do on the layout but it’s already made a difference.

Might seem like a small thing but an organised van means I turn up to your job with the right parts and tools, find them straight away, and spend my time fixing your heating instead of digging through boxes. Everything has a place now.

Full drawer for the power tools, sliding deck for the boilers and bigger kit, and all the fittings organised so I’m not carrying stock I don’t need.

Thanks to Yoke for a quality bit of kit.

Day out of the van today. Over at Worcester Bosch HQ for my G3 unvented refresher, it comes round every 5 years whether you like it or not.

Not a bad thing though. Unvented cylinders store hot water under mains pressure and if one’s fitted wrong or the safety controls fail, it can do serious damage. There’s a reason you need a licence to work on them, and a reason they need servicing every year.

Bore da from somewhere in the Vale.

Nothing dramatic today. Just the van, the sun, and a boiler that needed looking at.

That’s most of the job, honestly.

If yours is due a service or playing up, drop me a message or book straight in at boilercraft.co.uk
