Before I contacted this company, I was let down by previous plumbers that I would have used to remove old, water filled... radiators with a view to installing electric ones supplied and fitted by "Sunflow". I also had a gas combi boiler that I wished to replace with an unvented electric cylinder, (Gledhill PLTDR 120 supplied by their company at my request). Anthony (and his company) agreed to do both, THEN another plumber let me down that had been contracted to do a bath removal and shower installation. The change in plans didn't "phase" him at all. The entire job was done with skill (and perhaps a little extra patience than would be expected for a "bog standard" job). I'd recommend their team (and it WAS teamwork) to anyone.read more

Anthony has done loads of jobs for us and was the obvious choice for sorting out the central heating when we moved... house.
We had a full installation which consisted of a new Ariston boiler, new radiators and the complete pipework replacing.
We now have a wifi controllable system that works perfectly with the benefit of being able to control things from my phone.
The work was started on time and finished on schedule. There was no mess and everything was cleaned up at the end of each day, with no disruption.
For a professional and top rate service, I wouldn't look anywhere else!read more

Had an emergency last Christmas- no heating or hot water. Anthony came on Boxing Day to install a new Ariston combi... boiler with Wi-Fi compatibility. He had us up and running the same day. Later he installed new radiators throughout the house and installed a new shower in the main bathroom. Great quality, professionalism and willing to make suggestions and implement them to our benefitread more

After putting up with a boiler for 3.5 years , fitted by , probably the largest installer there is I finally decided ... it had to go!!!!!! Was sick of having to call for repairs . Originally I wanted a VALLIENT boiler . Anthony of AR JOHNSON responded very quickly &came forward with an acceptable quote. From his overall presentation & he was in a nice van I decided he was the man to do the job. He kept to schedule & did a first class job . He also altered a radiator on our second floor to “open loop” & this had had the good effect of saving 4 other radiators coming on so frequently. A knowledgeable & capable man .read more

We used A R Johnson to have some leaking pipework to our boiler replaced and the heating system flushed. Anthony was... very professional, arriving when he said he would and providing a timely quotation - the team arrived on the day and time booked in and got straight to work, they were very friendly and carried out the work to a high standard - they left no mess and once the work had been completed it was like they had never been there except now everything works flawlessly. Cannot recommend enough and would have no issues using Anthony and his team again for any work going forward.read more

A JOB WELL DONE! Anthony and his team did a fantastic job on fitting our new Ariston boiler and replacing most of our... radiators. They came to do the job on the days and times promised and finished earlier than expected. They are very clean and apart from the new radiators and boiler, you would not know any work had been carried out! They also removed all the old rads and the old boiler too. Also they fixed our non working toilet and replaced a kitchen tap at the same time also done to a very high quality. GREAT SERVICE AND I WOULD DEFINITELY RECOMMEND AR JOHNSON PLUMBING AND HEATING FOR ANY PLUMBING JOB NEEDING DOING!read more

After several attempts to find a plumber to carry out a boiler service and an outside tap installation, Anthony and his... team were recommended by a friend. We could not have been happier with the professionalism of this company. From the outset Anthony was easy to contact and arrived on site when promised. 1st class workmanship. Crystal clear communication. Polite and extremely knowledgeable staff. Value for money.
Their service and quality of work speak for themselves. We look forward to seeing Anthony again when we change our radiators and put central heating to the new conservatory.read more

ARJ fitted an Ariston CLAS One HE condensing combination boiler in the loft of my bungalow, to replace an old boiler,... cistern and header tank. This has made a great improvement to the working and running costs, compared to the old CH system.
The fitters were very competent, efficient, friendly and tidy. Since the system was fitted 4 months ago, it has performed faultlessly.
This company is reliable and responsive. The quote was very competitive and good value, considering the amount of work involved.
I commend this company and their products to anyone requiring a new or replacement boiler.read more

We have used Anthony and his team in the past for various adhoc requests around leaks and toilet flush repairs. I've... always found them to be very responsive, efficient and courteous. So it was not a great stretch when we decided to use A R Johnson when we wanted to replace our boiler with the latest most efficient combi as well as a large number of radiators that were showing their age. Once again no surprises - they turn up when they say they will, deliver to the agreed requirement at the agreed price. Affable, polite and efficient. Any glitches or issues are dealt with quickly. Easy to recommend.read more

Needing a new central heating system in a recently purchased 90 year old house, we were given good advice by Anthony... when he first came to look at the job, and we found that he has happy to explain each step of the removal of the old system and its replacement.The team arrived promptly and worked really hard on a job that was far from straightforward ( the house having undergone many alterations), with energy and good humour, and great expertise. We now have a really efficient system, with an Ariston boiler, and hope to see the team soon for the next stage of the renovation! Many thanks to Anthony, Scott and Dan.read more

Had terrible trouble getting a plumber to call so when he turned up as arranged, even phoning ahead to say he was on... the way things are already improving!!
Second ,no call out fee just to give advice on boiler and heating problems...bonus!
Gave me a few options and prices, so plans were made and date fixed. On the day supplies arrived early as promised, closely followed by the team. These guys cracked on with the job, smiling and laughing all the way. It wasn't long before I have a bunch of glistening white,toasty warm radiators and a new Ariston boiler quietly purring away giving me steaming hot water. A quick explanation about the controls and after care and off they went.
To be honest I cannot say a bad word about these guys.I would not hesitate to call them again or recommend them to anyone.Professional, hard working,courteous and friendly. Definitely 5 stars!read more

Anthony gave me very sound advice about a boiler with falling pressure. I'd assumed a system leak but he suggested a... check first on the pressure vessel. I was able to get this check done under my service contract with Worcester Bosch at no additional cost. They fixed the problem.
Without the professionalism, in depth knowledge and generosity with free advice from Anthony, I could still be chasing leaks that didn't exist!read more

6 things to consider before buying a new boiler
May 6, 2021
No Comments
When buying a new boiler, not only do you have to factor in the price of the boiler, there are installation costs to consider too.
It’s a big decision, so you need to make sure you get it right.
Examples of Our Boiler Installations
Ariston CLAS one 30 system boiler with a 250 litre Sapphire unvented pressurised hot water cylinder
These systems are normally installed in larger properties where there is a larger demand for hot water, ie 2 or 3 bathrooms where showers or baths are to be used at the same time. With the unvented pressurised Sapphire cylinders you are able to use all working hot water outlets, ie showers at the same time and maintain the same hot water pressure whilst all in operation. A very unique and beneficial attribute in the larger properties.
Ariston CLAS one 38kw condensing combination boiler
Ariston CLAS one 38kw condensing combination boiler installed including a variety of design column radiators throughout. These boilers are the largest domestic combination boilers Ariston have to offer in the combination range. They are capable of comfortably supplying up to 20-30 radiators when in use and also up to 2 x bathrooms. They deliver up to 18 litres of hot water on demand once a tap is opened.
Finding the right boiler for you
Combi Boilers
Combi boilers are the most common boiler type in the UK, found within over 70% of UK homes.
Combination Boilers work by instantly heating water from the mains as soon as a shower or hot water tap is turned on, making them efficient. They can operate with different fuels and are generally quick and easy to install, and do not require a separate water tank, which means they are cheaper to install and economical to run.
Conventional Boilers
Conventional boilers, also known by regular, heat only, or traditional boilers; are the next most commonly found
They have separate water cylinder and boiler to operate your central heating system.
Often found in older homes, but can be a great choice for properties with large water usage or multiple bath tubs.
Smart Boilers
Smart boilers are being increasingly popular, as they are controllable via smartphones or thermostat.
Smart boilers come with built in connectivity, but existing boilers can be “made smart” by fitting various Wi-Fi devices, such as the Ariston Cube S Net.
Our Ariston Boilers come with up to 12 years Warranty
