Which Brand Of Boiler Is The Best

Which Brand of New Boiler is the Best?

Technology evolves at such a rapid rate, and when we try to find out which brand of boiler is best to buy, we get a vast array of different answers year on year. Modern condensing boilers are similar in so many ways; however, every other detail counts.  The internal quality of the boiler's components is essential. Let's have a look at what types of new boilers are available at present. Please read our guide below. 

Types of Boilers


Short for Combination Boiler, these boilers don't need extra storage tanks, they provide hot water and heating directly from the boiler. If you don't live in a large house and don't have many bathrooms, then a combination boiler may be the best option for your home.

Combi boilers are also usually easier and cheaper to install, saving on your finances and time upfront. The best range of combi boilers combines high-efficiency central heating and heat hot water, within a single compact unit. Furthermore, combination boilers will deliver hot water through your showers and taps at mains pressure. So, providing your mains water pressure is good enough, you can enjoy hot water on demand from your taps and hot showers without needing to have extra pumps. Because you don't need extra space for tanks and cylinders, it means a shorter installation time and lesser pipework. 

If you have a larger property with two showers or multiple bathrooms and are considering a combi boiler, it may be inadequate or too small for your property. You don't have to worry. There are now larger combination boilers available which house within the unit itself a thermal water storage tank. You must make sure you choose the best combi boiler size for your property's size before installation.

This range is also well known as standard boilers. The technically accurate term for a conventional gas boiler is "Open Vent Boilers". Standard or conventional boilers require a cold water tank in the attic/loft and an additional hot water cylinder located elsewhere in the house. If you have a property with two or more bathrooms and you require hot water simultaneously, then a conventional boiler might best suit your home. 

A conventional boiler costs are relatively high compared to a combi boiler since it is a significant part of your central heating. Also, consider that if you are replacing an old Gas conventional boiler, other parts of the system may be ancient, which you need to consider. In many cases, the heating controls will also need to be renewed when you upgrade your new Gas conventional boiler.

Gas system boilers are suitable if you live in a home if you require more hot water than a combi boiler can provide or have more than one bathroom. A Gas system boiler could be your ideal hot water and heating solution. A Gas system boiler will pump hot water to a sealed hot water storage cylinder or your properties radiators. 

 Most of the heating and hot water system's major components, including the pump and expansion vessel, are built into the boiler making installation easier, tidier and more efficient and makes servicing a little more comfortable with fewer components to go wrong. 

Gas System boilers combine high performance and high efficiency with excellent energy-saving options over older heating system setups. The hot water and heating components are built into the boiler unit. A sealed system boiler requires a pressurised unvented cylinder for storing your hot water. Unlike a traditional conventional boiler, you don't require a cold water tank in your attic or loft.
