Which is the Best Boiler for a 3 Bedroom House?
Are you on the search for a new boiler to meet the heating and hot water demands of your 3 bedroom house? You don’t have to look any further than Worcester Bosch and Vaillant, two of the biggest brands in the industry.
With both of these manufacturers having suitable boilers on the market, we’ve put them head-to-head to crown the best boiler for a 3 bedroom house.
The Brands Behind the Boilers
Worcester Bosch started life in 1962 as an independent business before becoming part of the Worldwide Bosch Group in 1992. They’ve been awarded the ‘Best Buy’ boiler brand for seven years in a row and if that’s not enough, they currently supply heating products to the Royal Family.
Having been in operation for over 140 years, Vaillant have lots of experience in the industry. While they boast German design and engineering, their boilers are actually manufactured in the UK which means replacement parts are easy to come by.
More often than not, these two brands leave all other manufacturers behind in lists of the ‘top boiler brands’ and are left to fight over the number one spot. They’re both also consistently receiving high customer satisfaction ratings which makes these two very tough to separate.
Now that we’re familiar with the manufacturers, which one can offer the best boiler for a 3 bedroom house?

Worcester Bosch Greenstar 30i vs Vaillant ecoTec Plus 832: The Weigh-in
Both of these boilers are Combi boilers, combining the functions of a water heater and central heating boiler into one compact unit to heat water on demand. If your home has multiple bathrooms and a high demand for water, you might want to consider a System boiler which we go into detail about at the bottom of this article. You can find out more about the different types of boiler available for your home with our simple guide.
It’s only right to start any comparison with the definitive facts and figures, so we’ve put the Worcester Bosch Greenstar 30i and the Vaillant ecoTec Plus 832 side-by-side in the table below.
|Boiler Model||Worcester Bosch Greenstar 30i||Vaillant ecoTEC Plus 832|
|Dimensions in mm (HxWxD)||690 x 390 x 280||440 x 720 x 338|
|Standard Warranty||5 years||5 years (option to extend to 10 years)|
|Average Price||£950 – £1,000||£1,000 – £1,200|
|Mounting||Wall mounted||Wall mounted|
|Flow Rate||12.3 l/m||13 l/m|
|ErP Rating||A Heat, A Water||A Heat, A Water|
Price will nearly always be the determining factor in purchasing anything, let alone a boiler. With the Worcester Bosch Greenstar 30i, you’re likely to get a cheaper price compared to the Vaillant ecoTec Plus 832.
On top of this, there will be an installation cost which will vary depending on the work required. When looking for an engineer to carry out the work, we recommend getting up to 3 quotes from different engineers, rather than just the one, to give you the best chance of finding the right deal for you.

One difference between these two boilers is that the ecoTec has an energy efficiency rating of 89.3%, while the Greenstar comes in slightly higher at 94%.
If you’re not familiar with these ratings, the higher the percentage, the better the boiler is for the environment and your bank balance. So, with the Greenstar’s 94% efficiency, for every £1 you spend on heating your home, just 6p is wasted on lost energy. Get to know even more with our guide to energy efficient boilers.
Both boilers come with a 5 year warranty as standard but the warranty of the ecoTec can be extended to 7 years if you register it with an advanced installer. After doing this, you’ll be given the option to purchase an even longer warranty of up to 10 years, doubling the standard warranty.
With both of these boilers, you need to register your warranty to activate it and will then need to get the boiler serviced annually for the length of the warranty.
The ecoTec is the much shorter model, however the Greenstar is not as wide and won’t protrude as far out from the wall. Remember, both of these models will need to be mounted on the wall, so if your ceilings aren’t too high, the ecoTec could be for you but if you don’t have much space along the wall, then the thinner Greenstar will leave you with more room for storage.
These two brands are consistently neck and neck when looking at the best boiler brands and it’s almost the same story with these very evenly matched Combi boilers. Worcester Bosch and Vaillant have manufactured Combi boilers that boast many benefits, making it hard to pick an overall winner.
If you don’t mind paying a little bit extra, you can have your ecoTec warranty extended to 10 years (which is double the standard Greenstar warranty) for extra peace of mind.
On the whole though, the the Worcester Bosch Greenstar 30i might just take this one thanks to the smaller cost and the higher efficiency rating of 94% that will help you to save more money on your bills in the long term.
3 Bedroom Homes with a Higher Demand for Hot Water
The two models that we’ve compared here are Combi boilers which are extremely efficient and allow you to heat your home and water quickly as and when you need to, they also only consist of one individual unit which can save a lot of space in your home.
However, if your home has a particularly high demand for hot water (2 or more bathrooms), you may be better suited to a System boiler which incorporates a hot water storage cylinder. This store of hot water can supply lots of outlets at the same time without losing pressure. Both brands offer System boilers suitable for 3 bedroom homes with 2 bathrooms: Worcester Bosch’s Greenstar 30i System and Vaillant’s ecoTEC plus 630.
For the best recommendation, it’s wise to consult an engineer who will be able to find the right solution for your home.
