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. Therefore, it’s worth your while booking one of our Cardiff heating engineers to increase the efficiency of your boiler.

Most new boilers are condensed and they offer a huge improvement in efficiency. This is because they use waste heat in flue gases to pre-heat cold water entering the boiler. Our team of heating engineers specialise in these types of boilers and are fully qualified to install any type of boiler. If you require extra information with regards to boilers, visit our boiler installation page.

For peace of mind, all heating engineers at NJ Harkus are fully insured and are Gas Safe registered (518700).

Radiator Installation and Repair in Cardiff

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 Although radiators are in almost every home, many are outdated and are less efficient than the latest range, which come in all shapes and sizes to best suit your requirements.

Our skilled team of heating engineers can meet any requirements you may have and this can be anything from installing designer radiators to thermostatic control valves (TRV’s).

Power Flushing Service

Are you experiencing “Luke Warm” radiators, cold spots and noises? This is a sign of corrosion and sludge that has built up in your radiators. To resolve this issue is a method known as “Power Flushing” and it’s a service offered by our heating engineers in Cardiff.

After a power flush, the radiators will work more efficiently and it reduces your energy bills quite significantly because you’ll not need to increase the temperature due to the cold spots. It will also be far more reliable, which is a major requirement in the winter months.

Therefore, if you are looking for a secondary source of heat in your home other than the central heating system, get in touch for a free quote.

What Do Our Customers Say?

Nathan and his team are quality heating engineers – very friendly, professional and reasonable. Nathan responded to my central heating problem promptly and sorted it first time (unlike other plumbers in the past). Very tidy job and they left the room cleaner than they found it! I would definitely recommend them to anyone and I will be using NJ Harkus again for any future requirements. From quotation to start of job, communication was excellent.

Ian Davies

Nathan installed our new boiler 3 years ago and has just completed an annual service along with a bathroom radiator replacement. Nathan is the best plumber / central heating engineer in Cardiff that I have EVER known. Not only is he very friendly but he always provides excellent work and value for money with all the jobs that he carries out. I can’t recommend him and his team of heating engineers highly enough.

Pauline Jenkins

NJ Harkus are brilliant, friendly and trustworthy heating engineers in Cardiff and a team that I would highly recommend. Nathan fitted a new central heating system and has done multiple smaller jobs in my problematic little house – (his call out time is extremely short and often within the hour). I’ve been ripped off previously by other plumbers but I trust Nathan and his team with their quality of workmanship and their honest quotes that actually get stuck to.
