Feedback – Brilliant. Keith Kerslake Ltd did a brilliant job. Very informative and a 1st class installation with no complaints about my coffee-making skills. The boiler has only been in a week so a bit early to say a lot about it. Except, that we have so far seen a 100% improvement on the old one and we know that this installation is up to current regulations. I lived in Germany for 8 years and have always been a fan of German engineering.

Feedback – I have just had a boiler repair done by an engineer and when he left I noticed a slight leak I contacted customer service and they said they couldn’t come and sort it until I had requested my service contractor (that’s a whole other nightmare). I was then told by the customer service agent that their engineers do not make mistakes and that the leak must have happened some other way after he had left. to me, that suggests they are blaming us for tampering with the boiler. After speaking with Julie at Viessmann today I have changed my score slightly I still think a boiler retailing at £825 should not have had repairs done to it totaling £842 and that’s with £200 credit after only 4.5 years. I will get this boiler removed as soon as I can as I have no doubt it will keep costing me in years to come. My last boiler lasted 18 years with no flushes and no issues at service. Thanks again to Julie for all your help as without it this review would have been very different

Real-World Use Case:

Viessmann to the rescue after boiler problems. The fitting of a new Viessmann gas boiler by RBHM had been a nightmare. I’ll spare you the details but one of my many problems was their failure to leave me with the Benchmark commissioning sheet which is essential to obtain the Viessmann 10 year warranty. Eventually, I rang Viessmann and spoke to Suellen. She was in Finance (I couldn’t get through to anyone in Customer Service) but she didn’t fob me off, she listened patiently to my tale of woe. She was encouraging, assuring me that Viessmann would help me out: she would speak to a supervisor and they would get back to me probably the following day because by this time it was close to 5 pm. I can’t praise her customer service too high, it was exemplary. Then – about an hour later – I got a follow-up call from Ian, a Sales Director. He reassured me, he was confident Viessmann would waive the Benchmark commissioning document and honor the 10-year warranty. Given my problems with the MD of RBHM, this provided me with the peace of mind I wanted. Amazingly, Ian sent me an email later that same evening to confirm he would get this sorted and I got another 2 emails the following morning to say it had all been agreed. What impressed me about Suellen’s and Ian’s customer service response was that they were not only true to their word and got things done but they were so sympathetic and understanding. This is in marked contrast to several people recently who have tried to cheat and deceive me – and that includes lawyers and Tribunal judges! My faith in human nature was restored and I’m now a firm fan of Viessmann.

  1. How can I make my central heating system more efficient?

There are a range of steps you can take to make your central heating system more efficient. For example, if your existing setup is old or it doesn’t suit the requirements of your property, you could replace it with a new, more efficient model. Highlighting the possible benefits of this, if you live in a detached house and replace an old G-rated gas boiler with a new A-rated condensing model, you could save over £300 a year.You may also want to think about fitting better controls. Ideally, you should have a boiler thermostat, thermostatic radiator valves, a room thermostat and a timer or programmer. Make sure you know how to use these controls to keep your heating system running as efficiently as possible.

2. Which heating system is best for my home?

Deciding it’s time for heating replacement is one thing, but how do you know which system is right for your home? With so many solutions available, it pays to do your research – and you may wish to take expert advice to help you find a system that matches your priorities and the specific heating and hot water needs of your household.

3.How much will it cost to install my new heating system?

As well as paying for the heating system itself, you’ll need to make sure you budget for the installation. There are no set rules when it comes to costs, but generally speaking, the more complex and time-consuming the process of installing your new heating is, the more you can expect to pay. Also, having extra features added to your heating systems, such as a new thermostat or new radiators, will make installation more expensive. To ensure you’re getting a good deal on installation, you may wish to get quotes for this work from many heating engineers. Always make sure you choose an engineer with the appropriate skills and accreditation. For example, if you are having a gas boiler fitted, your engineer must be Gas Safe registered.

4.When is the right time to replace my heating system?

Knowing when to arrange heating system replacement isn’t always easy, but there are many signs that suggest it’s time to make a change. The occasional heating system breakdown may not warrant a replacement, but if your system needs to be repaired frequently, it could be time to get a new solution. Also, if your heating system is old and you find it difficult and expensive to source replacement parts for it, it’s worth considering making the switch to something new. It may also make sense to get a replacement if your current heating system isn’t working as well as it used to, or if it no longer meets the needs of your household. In addition, you may benefit from getting a new solution if your current system is proving inefficient and therefore costly to run.
