Are you looking for a combi boiler to deliver the ultimate flow rates to your large Edinburgh property?
If so, you’re probably already wondering if the Worcester Bosch Greenstar CDi Highflow 550cdi is up to the job! I’ve personally had experience installing many of these boilers over the years, and it’s one of the best there is when it comes to supplying lashings of hot water to your home!
However, don’t go jumping in just yet! It’s vital to get it right when investing in a new boiler for your home, especially if it’s going to last you the distance – which means looking closely at all the specifications and outputs first.
That’s why I thought I’d make it easy for you, by putting together this comprehensive overview of the 550 below. Happy reading!
Introduction
When it comes to combi boilers, the Greenstar CDi Highflow 550 is a full-on beast that actually leads the industry when it comes to providing the ultimate hot water flow rates to your taps – perfect if you have a large home with multiple bathrooms and a high demand for hot water.
Think of it this way – you’ll never have to worry about running out of hot water, despite the fact that your entire family seems to want a bath or shower at the same time! The 550 packs quite a bit more punch than its little sister, the CDi 440 (which I personally have installed in my own home).
Worcester Bosch is an incredibly reliable, premium brand, and this boiler will happily work away in the background for years without even missing a beat, due to its quality components and advanced features.
Output and flow rate
With a heating output of 30kw and provides a mahoosive 41.1kw to the hot water (supplying an outstanding 25 litres of water per minute) you’ll find the 550cdi is a behemoth that can take just about anything in its stride.
It’ll have no problem heating a home with around 10 – 14 radiators, although you should always get an engineer to measure your home’s heat loss just to make sure it’s the right output for your needs.
TIP: Before an engineer installs the 550, always get them to check your incoming water pressure to ensure you’re definitely going to see the benefit of these fabulous flow rates!
Size
One of the CDi Highflow 550’s downfalls arguably comes down to size – although to some, that’s not a huge (get it?) problem. Okay, bad joke. This is a standing floor boiler, measuring in at a whopping 850mm x 600mm x 600mm (essentially washing machine size).
So, if you’re planning on buying this boiler, you’ll need to ensure you have somewhere to store it, such as a walk-in cupboard, basement, or garage. It can also slot under a kitchen unit if you have extra space in your kitchen.
Guarantee
Being a CDi model, the 550 also comes with the best no quibble 10-year boiler guarantee on the market right now (when fitted with Worcester Bosch Greenstar filter and controls – which are also covered for 10 years). But remember, this will be subject to your boiler getting its annual service.
Worcester Bosch also has dedicated engineers on-hand to attend call-outs if anything goes wrong, so you can be rest assured it’ll be in safe hands!
