Are you in need of a direct replacement for the old regular boiler in your small-medium 3-bedroom Edinburgh home?

Many of my customers have old, regular boilers and don’t always want the upheaval that comes with switching to a combi – and I tell them the Worcester Bosch Greenstar ri range is the perfect solution.

I’ve put together this review so that you can learn more about the Worcester Bosch Greenstar 15ri, and make the best decision for your home.

Introduction

I’ve fitted many of these no-fuss boilers in properties where the old regular boiler has just become too old and is in serious need of an upgrade.

The Worcester Bosch Greenstar 15ri is an easy fix, and can be installed in just 3-4 hours. So, all of your radiators, pipework and tank can just be left in, the boiler replaced and the system flushed out – simple as.

This is a great choice if you’re satisfied with your current store of hot water and want to leave your tank where it is, as it’s what’s known as a direct replacement. Another huge bonus is that it’s also a high efficiency condensing boiler that will cut your carbon footprint and reduce your energy bills.

Output and flow rate

The heating and hot water output is 15kw on this particular model, so it has a bit of extra oomph than the Greenstar 12ri, and is really ideal for small-to-medium properties with around 6-7 radiators.

However, if you have a larger 4-5 bedroom stone-built property, with high ceilings and not a lot of insulation, you’ll likely require a larger boiler to comfortably heat your home.

To be on the safe side, I’d recommend asking your chosen engineer to measure your home and work out the heat loss and the output of boiler required – most likely the 18Ri or 24Ri might be the best option.

Also, because this is a regular boiler, it’s wise to get your engineer to check your pipework is up to specification before fitting. Because this is a high efficiency boiler, it is not compatible with gravity hot water, and has to be fitted with a fully pumped system.

Size and special features

The Worcester Bosch Greenstar 15ri is a compact boiler that will happily fit in your kitchen cupboard or Edinburgh press – which is ideal if you don’t have a lot of space in your home.

Another great feature of this boiler is that it is compatible with solar heating – which makes it future-proof if it’s something you’re considering in the next 10 years.

Guarantee

This boiler comes with Worcester Bosch’s fantastic no quibble 8-year boiler guarantee* so you’ll be covered on the off-chance anything does go wrong.

That’s particularly good news, as Worcester Bosch currently has the best boiler guarantee* on the market. It’s true that there are longer guarantees out there from other boiler companies, but there’s often a catch in the small print, or extra credit card charges before they’ll even agree to a call-out (Vaillant is an exception to this).
