NEW BOILER

Heat Tech were asked by us to quote after hearing great reviews from other customers. We went ahead and everything happened as explained and planned. The actual week long work flow went like a dream. Our 18 radiators were cleaned out, the new boiler fitted, tested and working. What was special was that Marl and his team were on time and took time to explain each step. Mark also worked out a smart way for our complete new heating system to avoid unsightly external pipe work so that everything is neatly confined within the roof space. All work was also made good to a very high standard. Mark and his team also worked through the UK's hottest days on record. I highly advise others to contact Heat Tech on any major domestic heating or plumbing project.

Mark on a Saturday evening talked us through a leaking boiler issue we had. Via WhatsApp pictures and over the phone he gave us clear and concise instructions. He resolved the problem and was calm, clear, and amazing throughout the call. When this COVID 19 issue is over we will be using him again to service our boiler. Would not hesitate in recommending him. Reliable reasonable service.

Very easy booking on the phone. Engineer arrived on time and explained what was work was being carried out. I had a couple of concerns with the boiler running on it's own when not on timer, which were professionally answered and cleared up those queries for me. Price was as quoted, will use Heat Tech again.

On one of the coldest days so far, we had a problem where our boiler became faulty and would not light up, so had no heating or hot water. Called Mark in the morning and within a few hours he had been round to diagnose the problem and then sourced a replacement part and fixed the problem shortly after. We could not of hoped for a better response and service. We have used Mark for a number of jobs over the last 6 months and highly recommend him and his team. Very professional and helpful.

I was lucky enough to be introduced to Mark when I first moved to Rickmansworth in 2014. He and his team had done work for my son, so I had no hesitation in asking him to do some things that were that needed here. He installed a new Combi boiler, with all that that involved, disposing of the old boiler and enormous tank. He also took away an old radiator and replaced it with a new one on the opposite side of the room. Since then, he and his team have regularly serviced the boiler. Mark has an excellent work ethic which he passes on to new members of his team. I have no hesitation in recommending Heat Tech.

We were quoted a repair date for the problem with our boiler of 10 days from our long-standing Service Supplier which was unacceptable because of the cold weather which left us with no heating and no hot water. Heat Tech came within 2 hours of a telephone call, identified the issue and fixed the problem. We have now cancelled our contract with the previous Service Supplier.

I contacted Heat Tech Services in the morning in relation to a fault on my boiler, it wasn't producing hot water. Mark got in touch with me about half an hour later and at 2 pm I had an engineer at the door. He diagnosed the fault immediately and fixed it. The engineer even waited some 10 minutes for access while I returned home. Other companies were going to come the following week and, with 2 small kids at home and an elderly grandmother, I desperately needed hot water in the house. Honestly, I couldn't rate this company highly enough. I was so impressed with their service. I used them for the annual boiler service last year and will certainly continue using them in the future. Thank you, Heat Tech!

Mark was recommended to me and with good reason. He was the third plumber/heating engineer to attend in the 8 days we were without heating or hot water. Expensive solutions had been diagnosed by the others e.g. new boiler! They say that planning is the key to success... In advance of the appointment, Mark asked me to send photos of the boiler, the pump the immersion valve etc. On the day of the appointment he attended with his (very polite, articulate and proficient ) young apprentice. They were outstanding. Heating system drained, pump replaced, radiators warm and hot water restored within 90 minutes of arrival. Having received the photos, he had been able to ensure that he had all possible parts on board should they be required. I am very impressed by the professionalism of all aspects of Heat Tech, not least as the problem was swiftly identified and fixed at a fraction of the cost I had been advised by the companies.

Mark attended my property with his assistant Ethan. The work was carried out efficiently and cleanly on the agreed day at the agreed time. Upon completion Mark provided advice for the future of my somewhat elderly boiler. An invoice for the amount agreed beforehand was provided by e mail two days later. All in all a thoroughly professional service which I would gladly recommend.

We have been using Heat Tech for many years now for servicing and repairs and wouldn't dream of going anywhere else. Mark and his team have always been completely dependable and very professional. My last issue was that our heating system broke down on Christmas Eve (just gone). Whilst I knew that this would be an awkward time to expect anyone from Heat Tech to do anything, Mark came round on his way back from Christmas shopping to have a look at the problem, which wasn't an easy one to diagnose or repair. Nonetheless, across three visits that day, Mark managed to solve the problem, replaced a faulty valve and get us up and running with a fully working heating system again over Christmas! Needless to say, we were delighted and relieved, and despite the time of year, the bill was very reasonable too. I would have no hesitation (and frequently do) to recommend Heat Tech to anyone that like us, truly values a reliable, professional and totally trustworthy service from any contractor.

Mark has always been excellent. Had a problem with some of the radiators not working. He suggested changing the pump and the effect was immediate. He is straightforward and hard working and more to the point very honest. All these attributes and rare.

Left a message for Mark re radiators getting warm when only hot water activated. Dripping and vibrating cold tap. Boiler service. He returned my call the same day and said it could be dealt with the next day. The next afternoon, at the appointed time, arrived Engineer Sapphire and her assistant Ethan. They were thoroughly professional, polite, efficient and tidy. I can’t speak highly enough of the whole service. Everything was fixed and for a very reasonable price. I would have no hesitation in highly recommending Heat Tech and I would certainly use them again.

Mark and his team have done work for us a few times. Mark is always very responsive and arranges for the work to be done quickly. His team arrive when they say they will, always do a good job and clean up after themselves. Also the pricing for the job is always competitive and reasonable. We will use Heat Tech's services again and I would highly recommend them.

Having not used this trader before, I was very impressed with the service provided and would highly recommend them. I needed someone to repair my toilet cistern as it was constantly trickling through the pan. They contacted me quickly to arrange my appointment and confirmed it in an email with details as to who to expect the following day. Neil came out as planned and fixed the problem. Excellent service.
