Things to Consider When Choosing the Right Boiler Brand for Your Needs
Check out the given points while choosing from a myriad of boiler brands.
Types of Boilers
There are mainly three types of boilers offered by any brand. Have a look at these types to make an apt choice.
Regular or Conventional Boilers
These are open-vent boilers that consist of a water cylinder (for cold water) and a water tank (for hot water). First, the cold water gets heated and moved to the tank, then; it is pumped via the boiler system when the thermostat operates.
- Excellent for places with more bathrooms and more hot water needs
- Good choice for low water pressure areas
- Solar panel compatible
- More space requirement
- Complex installation
Worcester Bosch has excellent regular boilers with different output ranges and sizes to cater to your home’s hot water demand.
These are excellent in providing central heating water and hot water from one unit and are hung on walls. Since there are no separate cold or hot water tanks, the boiler takes cold water from the main water supply and sends it to the heat exchanger present in the boiler.
- Perfect for small flats and limited space properties
- Relies on main water pressure
- High boiler efficiency
- Easy installation
- Not suitable for large space properties
Viessmann Vitodens family comes with a wide variety of combi boilers. Backed by a 12-year warranty, the smart boilers come with class-A ErP, hydrogen-blend fuel support, and stainless steel heat exchanger, making them the top choice in the category.
They are an update to the regular boilers and serve as the middle-ground of both regular and combi boilers. The flexible installation comes from pre-installed components. Also, there is no need for a cold water tank as the water comes directly from the mains.
- Suited for large space properties with more bathrooms
- Flexible installation
- Solar panel compatible
- Not good for limited-space homes
- Not ideal for low water pressure areas
Price is a crucial factor when researching different boiler brands. The budget can make you switch from one brand to another easily. There are several boiler brands available in the UK. Some offer cost-effective solutions, while others can squeeze more out of your pocket.
If you are a little tight on budget, then you can go for brands like Alpha, Vokera, Glow-Worm, and Bai to find budget-friendly heating solutions. They offer a wide range of products with excellent customer service.
However, when budget is no problem, you can opt for brands like Worcester Bosch, Viessmann, ATAG, and Vaillant, where you will get a premium range of products focusing on quality comfort and smart functionality.
There are mainly 3 types of fuels used by boiler brands in the UK. Read more about them in detail below:
A gas boiler is a popular choice in the UK and offers high reliability and convenience. This is due to the fact that they are significantly cheaper than others since kWh for gas boilers is lower. It is a go-to option for people looking for super affordable boilers.
Most brands are now working towards a cleaner gas option with a blend of hydrogen gas. It will help in reducing carbon emissions.
The Liquefied Petroleum Gas (LPG) boiler comes in gas canisters and contains a mix of different hydrocarbon gases. It is an ideal option for limited-space homes owing to their smaller size. However, since it is a fossil fuel, it produces carbon emissions. These boilers are cheaper to buy than both oil and gas boilers.
An oil boiler comes with more responsibility and control than the other options. It is a renowned choice for off-grid homes and a financially viable option for more heat output. Since it is not readily available on-demand, you need to keep a large storage tank and regularly monitor it for refilling it with oil.
Before going for this option, you must check its upfront costs and note that keeping an oil reserve is a flammable affair.
Here is a comparison table for these fuel types of all the above-mentioned brands.
|ATAG||Yes||Conversion Kits available||–|
|Ideal||Yes||Conversion Kits available||–|
|Intergas||Yes||Conversion Kits available|
Size & Output
Picking the apt boiler size depends on 2 main aspects, the boiler’s physical size and its capability to heat water. This capability is its output measured in kilowatts (kW). Now the main rule to remember here is that the more hot water and heat you require, the higher the kW boiler is what you need to go for.
Now you know that every home has unique boiler size needs. Thus, you must look for boiler brands that meet your home’s heating needs to get the perfect boiler. It is because an undersized boiler wouldn’t work efficiently, while an oversized one would cost more to heat the whole place properly.
There are 2 energy efficiency ratings by the European Energy Label.
- ErP (Energy Related Products)
ErP has been widely prevalent since 2015 and rates your boiler efficiency using a unique grading mechanism that has grades from A+++ to G, where A+++ means highly efficient boiler. It comprises 2 rating elements, space heating, which measures the efficiency of heating radiators and water heating, which measures the efficiency of heating hot water for both taps and showers. While regular boilers come with ErP’s space-heating part, the combi boilers have both space-heating and water-heating parts.
With Boiler Plus legislation introduced in 2018, all boilers must have 92% ErP efficiency (A-rate) in England.
However, the Worcester Bosch Greenstar range and the Viessmann Vitoden family are popular choices in the market when it comes to energy efficiency.
- SEDBUK (Seasonal Efficiency of Domestic Boilers in the UK)
SEDBUK rating was introduced in 2009 for comparing and classifying boilers based on their fuel-to-heat conversion efficiency. Currently, you will find 2 types of SEDBUK ratings, namely, SAP winter efficiency and SAP hot water efficiency. Where SAP winter efficiency determines the boilers’ efficiency for hot water and space heating, SAP hot water efficiency measures the boilers’ efficiency for hot water in taps.
At this point, you will be familiar with the top 10 boiler brands available in the UK and what you need to know while choosing the right brand for your setting. Analyse all the points in the guide and try to pick the brand that caters to your needs and offers a boiler that fits your budget.
