What Customers Say

Dr Meena Hindmarch, Daily Telegraph Competition Winner, UK

"With our old boiler, the water in the shower always ran cold if the dishwasher was on at the same time. On the other hand, our new ecoTEC exclusive has no problem providing instant hot water at all times, and our installer says it will stay that way even when we extend the property later this year"

Terry Kennerson, The happy boiler company, UK

"Vaillant’s products are fantastic, even the entry level models are better than the competition because they use high quality materials for their components. I always encourage my customers to choose Vaillant because it’s worth investing in quality to get value for money overall. It also makes our business look good as we don’t get recalled to jobs where the boiler’s packed in after two weeks."

"Our ground source heat pump has completely changed the way we heat our home, it’s fantastic. Our electricity bills for a four bed property are now less than our gas and electricity bill in our old house and the temperature is always stable, I’d recommend anyone thinking about renewable energy to consider investing in ground source, the long term benefits far outweigh the upfront cost, and the RHI payment helps offset a large amount of the cost as well."

“Vaillant breaks new ground – they have the courage to be innovative and always search for the best solution. This is what we believe in. I have been an engineer in supply technology for 20 years, and I have known Vaillant for all this time. They have been a reliable partner throughout the years.”

Dirk van Stappen from Vianen, Netherlands

“I moved into my house 30 years ago. At that time, the building owner chose a Vaillant heating system. The boiler did a good job for 30 years, and I never had any problems with it. That’s why there is no doubt that I would choose a Vaillant boiler again.”
