I currently have a Vaillant ecoTEC Plus 438 system boiler which is 13 years old. I have been having problems with the boiler which boils down to the heat exchanger so I am now looking to bite the bullet and have a new boiler installed.
My set up at home is that I have a 4-bed detached with 21 radiators (includes 4 towel rails), a 6m x 4m orangery/conservatory that was built last year with under-floor heating, and a Megaflo for storing hot water. Last year, I had all my radiators changed and the main pump upgraded to a Grundfos UPS2 25-80 pump. I control the hot water, central heating, and UFH through the Heatmiser app.
I have been in discussion with a few plumbers and they have recommended either the Vaillant EcoTEC Plus 637 (37kW) system boiler or the Worcester Bosch 8000 boiler. I have found that those who are accredited as Worcester Bosch installers recommend the Worcester Boiler as it gives you a 12-year warranty whilst the Vaillant accredited installers receommend the Vaillant boiler (as it comes with a 10-year warranty). Some of the plumbers have no preference, they are happy to fit either. The advantage of the Vaillant they say is that you have more control on the Vaillant in terms of what you can set it to, and to make adjustments.
Can anyone recommend which boiler I should go for?
