Whether you’re looking to upgrade your current setup to a Worcester system boiler, or not sure whether a combi boiler upgrade is where you should be investing your cash; this quick-fire guide has everything you need to know.
Upgrading your system isn’t going to be cheap – you need to do your research.
So, below we’ll cover the likes of the Worcester system boiler range, prices and installation costs, as well as the best alternatives available right now.
A system boiler builds up a store of hot water in a cylinder. This isn’t the same as a combi, where water is heated on demand.
Basically, you’ll be able to use a lower KW output appliance when using a Worcester system boiler, when directly compared to a combi.
More importantly, you’ll have a bigger supply of hot water on demand, making system boilers suitable for properties with a high hot water demand (multiple showers and taps running at the same time).
That’s the basics. If you want to learn more, you can read our detailed guide to system boilers here.
It might be that your current system boiler setup is overkill for your property. And, that means you could upgrade and save space by switching to a combination boiler.
Typically, you’ll find that switching to a combi boiler is going to cost £700 on top of a standard installation. The additional cost covers labour to remove the existing hot water cylinder and then install a combi boiler.
However, there are companies like BOXT that will only charge in the region of £300-500 for an upgrade as part of their system boiler installation packages.
Worcester’s boiler prices aren’t going to be the cheapest. They’re a reputable brand that consistently win awards such as “Which? Best Buy” and can be found from installers like BOXT with a 10-year warranty.
The system boiler range consists of the Greenstar:
Prices are likely to vary from £800-£1400, with £800 getting you something like the 12I, and £1400, something like the 35CDI Classic system.
Remember, that’s the cost for the boiler only, and doesn’t include parts such as the cylinder, flue, boiler filter, copper pipe, or labour.
A typical Worcester system boiler installation is going to cost a lot more than a combination boiler installation.
You’d expect to pay around £2,000 at the low end for a combi, whereas the smaller system boilers are likely to be in the region of £2,400-£2,500. We found the 12I on BOXT for just over £2,400:
But you could upgrade to something much bigger such as the 27I Compact for around £150 more.
So, whilst the cost of the actual boilers vary a great deal, the overall installation costs are similar, regardless of the size boiler you need.
We’ve already wrote a guide on how to size up your combi boiler, but that’s irrelevant here. As system boilers store water in a hot water cylinder, you’ll be using a much smaller KW output boiler compared with a combi.
Like combis though, the size needed is all going to depend on the size of your property, and your demand for hot water. For example, a property where only 1 tap or shower is used at once, is going to need a completely different boiler to one using 2-3 showers and/or taps at the same time.
The quickest and easiest way to determine which size Worcester system boiler you need, is to use this boiler size calculator; the most suitable will be listed at the top of the search results, after filling out a few multiple choice questions about your property.
There’s a good chance you already know Worcester are up there with the premium boiler brands on the market.
But, it’s always worth checking out recent reviews. Unfortunately, you’re unlikely to find them on Amazon and the likes.
However, there are plenty of positive reviews worth reading over on Trust Pilot.
Worcester system boilers aren’t just popular because they’re a well-known brand, nor because they’ve won multiple awards.
The fact is, when you’re spending in excess of £2,000 on a boiler installation, you want to make sure you’re getting a long warranty. Otherwise, just a few years down the line, you could be footing some expensive repair bills.
Worcester system boilers can be found with a warranty of up to 10-years from installers like BOXT. In comparison, the highest warranty on Vokera boilers is 7-years (Vokera Evolve), and some boilers on offer (Vokera Mynute) are only being offered with 2-years.
In our opinion, you should be heading for a boiler that has a minimum of 5-years warranty.
Although we rate Worcester system boilers, it’s not like there aren’t other brands offering reasonable alternatives at competitive prices. Brands such as Ideal, Vaillant, Potterton and Viessmann are all worth a look.
For instance, you’ll get a 10-year warranty on the Ideal Vogue system boiler. That’s a leading brand featured in our best boiler manufacturer list, and it used to be that Ideal were on-par in terms of quality, but slightly cheaper.
However, now Bosch part own BOXT, BOXT can supply Worcester system boilers at incredibly competitive prices, so Ideal don’t really have the price advantage they once had.
