If we can’t fix it we know a man who can!

There was a time, back in the 50s and 60s – when most car owners were their own home mechanics. They knew how to change the oil, reset the points, or clear a blocked fuel line. Some even went further. A friend of mine from the North said that in his home town Bank Holiday Monday was known as the Annual Decoke Festival, when every man was out tinkering under his car bonnet. Remember Haynes manuals, anyone?
Of course nowadays, even if we wanted to take it on, advances in technology mean that motor mechanics is a closed book to most of us. Forget a set of spanners and an oily rag. In the modern world you need to be a computer diagnostician.
It’s a bit like that in the heating and plumbing industry. Technology has moved on apace, and boilers and central heating systems have moved on with it. On the plus side they’re more efficient and powerful than ever, but they’re also infinitely more complex. So when they do go wrong – as even the best of them do on occasion – you need someone who knows what they’re doing to fix it.
Even qualified HVAC engineers like ourselves need a bit of back up from time to time. And in that we are very fortunate because, as agents and distributors for Worcester boilers – generally recognised as being one of the most advanced on the market – we have access to their Technical Support Team, which advises us on a range of system and boiler issues, including leaking systems and blocked heat plate exchangers.
Both Worcester and ourselves are firm believers in the principle that prevention is better than cure, and this is especially true when installing a new system or a replacement boiler. One of the key reasons that systems lose pressure and perform poorly is the build-up of lime scale, which is a particular problem in hard water areas like Bishop’s Stortford.
High performance boilers are especially vulnerable to this, as the chambers between their heat plate exchangers are wafer thin and can easily become blocked if there are contaminants in the system. To prevent this we are always careful to flush and clean out an old system before fitting a new boiler. In addition we will always advise using an inhibitor and systems filter for long term protection, as well as a scale prevention device on the cold water mains.
Modern condensing and combi boilers operate at higher pressures than traditional open vent systems, as a result of which our engineers are extra vigilant to prevent leaks and pressure loss.. We approach the original installation, and ongoing maintenance like a pilot doing a pre-flight check, paying particular attention to joints, radiator and pressure valves and automatic vents (the latter for signs of discolouration or contamination that could signal a leak).
If you want a definition of progress and civilisation, the supply of hot and cold running water – and all the creature comforts that come with it – must come near the top of anybody’s list. At Harpers and Worcester we work hard to keep the technology and its application up to speed!
