Next up in our series of Greenstar CDi Classic reviews: today, we’ll be getting to know the Worcester Bosch Greenstar 35CDi Classic system boiler. As the most powerful system boiler in Worcester’s Greenstar range, it’s no surprise this model is popular with large, busy families. Our Greenstar 35CDi Classic System review gives you all the essential details, so you can decide if this boiler is right for your home.
Founded in 1962, Worcester Bosch is the best-known boiler manufacturer in the UK. The company has a strong presence in Europe, too, where it faces stiff competition from German manufacturer Vaillant. Here at home, Worcester Bosch has long reigned as the market leader, thanks to its range of highest-quality, energy-efficient boilers for every type of property.
Will the Greenstar 35CDi Classic System be suitable for my home?
The Worcester Bosch Greenstar 35CDi is suited to large homes with 5 to 6 average-sized bedrooms or 4 to 5 large, airy bedrooms. It does a great job of supplying hot water to more than one bathroom. If you’re thinking of buying this boiler, it’s more important to count up your radiators than your rooms. You need to make sure your boiler can supply hot water to all your radiators at once. The Greenstar 35CDi Classic System is made to handle 12 to 18 radiators, which is really a lot for a domestic property.
If you’ve looked at combi boilers, you will have seen that their flow rate matters a lot. A combi boiler’s flow rate determines how much hot water it can provide at one time. With system boilers like the Worcester Bosch Greenstar 35CDi, flowrate isn’t a consideration. That’s because a system boiler takes hot water from a large storage cylinder, rather than heating it instantly as a combi boiler would do. As such, it can provide a constant supply of hot water to all your taps at the same time, without any loss of pressure. The Greenstar 35CDi also has a powerful central heating output of 34kW, which makes sure your central heating runs efficiently, too.
If you’re weighing up options from different manufacturers, consider the Vaillant 637 Plus 37kW System boiler. It’s likely to offer you the same level of performance. If you have a slightly smaller property, say 3 to 5 bedrooms with 10 to 14 radiators, you might want to go one model down in the Worcester Bosch range: the Greenstar 30CDi Classic System boiler could be a better choice.
