Highly professional and pleasant service engineer .
I have had a perfect customer experience from Vaillant today. Hakan, the engineer, gave me a 30 minute warning of his arrival, carried out a thorough service without leaving any mess and answered all my questions with supreme patience. That’s not the usual response to a non-technical 80 year old with a failing memory! It was a pleasure to meet such a kind, cheerful and experienced workman. Many thanks!

Second Echo Tech Boiler
These boilers are easy to use and very efficient. We've just had our 16 years old Vaillant Eco Tech boiler replaced with the newer version. Apart from routine annual safety checks we only had a couple of faults, the pressure vessel had to be replaced after about 7 years and the main circuit board developed a fault a couple of years later. Both repairs were quickly resolved at a reasonable price. During the past year the pressure has been fluctuating, going very low during the winter and very high during the summer months but the boiler continued to work as usual. After 16 years service we decided to invest in a replacement and we're very happy with the result. Thanks to HMT Plumbing Lincoln.
