Experiencing costly heating bills? It’s estimated that an average boiler can be as low as 60% efficient, which means only 60 pence of every pound spent on heating is being put to good use.
Mostly all new boilers are condensed, which results in a large improvement in efficiency by using waste heat in flue gases to pre-heat cold water entering the boiler. Our team of engineers are fully qualified and able to fit almost any kind of boiler. For more information, visit our boiler installation page to read more.
For complete peace of mind, each of our heating engineers are fully insured and we are Gas Safe Registered (518700).
Central heating is the most cost effective way to heat your home and reduce dampness. Although radiators are in almost every home, many are outdated and are less efficient than the latest range, which come in all shapes and sizes to suit your requirements.
Our skilled team of engineers can meet any requirements you may have, which could be anything from installing designer radiator to control valves (TRV’s).
A certificate can only be issued by a Gas Safe Registered Engineer, which every engineer at NJ Harkus Ltd holds. Visit our Landlord Gas Safe Certificate page for more information.
Are you experiencing “Luke Warm” Radiators? Cold Spots? Irritating Noises? This is a classic sign of corrosion and sludge which has built up in your radiator over time. The cure is a method known as “Power Flushing”.
After a power flush, the radiator will work efficiently, which reduces fuel bills as you will not need to increase the temperature due to cold spots and most importantly it will be more reliable.
Our qualified team of engineers are able to install a wide range of fireplaces such as multi fueled wood stoves, electric stoves, gas stoves, central heating stoves, cooking & heating stoves and many more.
