Things to consider when buying a gas boiler

We appreciate that choosing a gas boiler is no easy task, so we are here to assist you. So that we can recommend the most suitable gas boiler for your property, we will guide you through the following considerations:

  • The kW output of the boiler

The kW output determines a gas boiler’s ability to cope with the heating and hot water needs of your household. To ensure that we are correctly sizing a boiler for you, we will take into account the size of your property, the number of bathrooms, the number of radiators, and the level of hot water is called for at the same time in your household.

  • The type of gas boiler you require 

Gas boilers generally come in three distinct types – gas combi boilers, gas system boilers, and gas conventional boilers. The key difference with these is that combi boilers don’t require any additional system components, system boilers require a separate hot water cylinder, and conventional boilers require a hot water cylinder and a header tank in the loft.

We go into detail in explaining the difference between these boiler types in the following guide:

Gas boilers vary greatly in size – with freestanding, wall hung, and boilers suitable for installing in a kitchen cupboard all available. To ensure we are recommending the correct gas boiler for your needs, we will ensure you have sufficient space in your property to allow the boiler to be installed in accordance with manufacturer recommended clearances for servicing, maintenance and the flue output.

  • The installation location

We will also assist you in considering the most suitable installation for your new gas boiler. As well as varying greatly in size, modern gas boilers can be installed in various locations in a property including an airing cupboard, utility room, garage, kitchen, bedroom, and bathroom. However, not all of these locations will be suitable for your property 

  • The quality of the components 

To ensure you are provided with a gas boiler that provides both reliability and efficiency, we always consider the quality of the components that are utilised within the boiler. We only recommend gas boilers that utilise stainless steel heat exchangers and don’t use plastic parts.

  • The efficiency of the boiler

All the gas boilers we install are A-rated and are over 90% efficient, this makes them much cheaper to run. If you go from an old back boiler to a new A-rated condensing gas boiler, the savings on your energy bill can be up to 40%. We have illustrated the cost savings available by installing a new gas boiler, below:
