Looking for the perfect system boiler for your small Edinburgh home?
The Worcester Bosch Greenstar 12i system boiler could be a great choice if you have a flat or small property. Especially if you currently have a regular or system boiler already in your home! Upgrading from a regular boiler to a system boiler isn’t as tricky as you might think, and it means a much more efficient system.
It also means you’ll have all the hot water you’ll ever need – and the option of installing an unvented cylinder for even better flow rates!
But how will you know if the 12i is the best system boiler for you?
Well, I’m about to use my experience as an engineer to tell you all you need to know about the Worcester Bosch Greenstar 12i system.
Introduction
This is a great little boiler for small properties. I’ve fitted quite a lot of them over the years, for customers who are looking for a more efficient replacement for their old regular boiler. See, they have an existing expansion tank, but are usually looking to upgrade their old one-pipe system.
System boilers tend to be a cleaner, quieter and more efficient alternative to regular boilers. Although, switching to a pressurised system can mean a of upheaval, most of my customers seem to think it’s worth the effort (unless they have sealed or concrete flooring – then they might think twice!).
Output and flow rate
Time to get started by looking more closely at the basic output to the heating and taps that you can expect from the Worcester Bosch Greenstar 12i system boiler. With an output of 12kW to the heating and hot water, this boiler is ideal for a flat or small bungalow with 4 – 6 radiators.
Unfortunately, this boiler isn’t suited to larger properties, but the good news is that there are plenty of different models in this range. Your engineer should be able to help advise you further (by measuring your home’s heat loss), but it shouldn’t be much of a difference price-wise to size up.
Most importantly, you need to check your pipework can handle this high-efficiency boiler. It has to be fitted with a fully-pumped system.
Wait, what about flow rates? Well, because this is a system boiler, it will heat your existing or new hot water cylinder. You can expect the same flow rates as you’re accustomed to in your home. Alternatively, these can be fitted alongside an unvented cylinder to give you an even better flow rate to your taps.
Size and special features
The Greenstar 12i is a wall-mounted boiler. Measuring in at 710mm x 400mm x 330mm, it won’t fit in a standard-sized kitchen cupboard. However, it will fit right in on your kitchen wall, or in a larger storage cupboard.
Don’t forget, the 12i can also be combined with Worcester Bosch’s range of high-efficiency indirect or solar compatible Greenstore cylinders.
