Best boiler for a flat & apartment

Selecting the perfect boiler for your apartment or flat can be a daunting task with the vast variety of options available on the market. In this comprehensive guide, we will explore the most suitable boilers for apartments, considering crucial factors such as boiler type, output size, physical size, efficiency, and warranty.

Types of Boilers and Boiler Sizes for Apartments

Before purchasing a boiler, it’s essential to consider the boiler type and size based on the output in kilowatts (kW) rather than the boiler’s physical dimensions. The ideal size for your apartment will depend on the demand for hot water, number of bedrooms, bathrooms, and radiators.

Combi Boilers for Apartments

A combination or ‘combi’ boiler is an excellent option for apartments, as it is a gas boiler that merges a water heating system and a central heating unit. This design provides instant hot water, eliminating the need for a separate hot water tank, and takes up significantly less space in your home.

Output in kW Bedrooms Bathrooms Radiators
24-28 1-2 1 Up to 10
28-35 3-4 1-2 Up to 15
35-43 4+ 2+ Up to 20

System Boilers

System boilers take water directly from the mains and heat up your central heating system while producing hot water for a water storage cylinder. This type of boiler is a suitable option for apartments with fewer bedrooms, bathrooms, and radiators.

Output in kW Bedrooms Bathrooms Radiators
12-15 1-2 1 Up to 10
18-24 3-4 1-2 Up to 15
30+ 4+ 2+ Up to 20

Regular Boilers

Regular boilers, also known as ‘conventional’ or ‘heat only’ boilers, store hot water in a cylinder instead of providing on-demand hot water like combi boilers. They can meet high demand for hot water at once, making them ideal for properties with multiple bathrooms.

Output in kW Bedrooms Bathrooms Radiators
10-18 1-2 1 Up to 10
18-26 2-3 2-3 Up to 15
27-40 4+ 3+ Up to 20
Cylinder Capacity (Litres) Bedrooms Bathrooms
120-150 1 1
180 2 1
210 3 2
250-300 4 2
300+ 4+ 2+

Physical Size and Compact Boilers

For apartments with limited space, compact-sized boilers are an ideal choice. Many manufacturers offer small-sized boilers that can fit in a kitchen cupboard or small airing cupboard. Combi boilers are the most compact option, as they don’t require additional storage space for water tanks.

Boiler Efficiency

Higher efficiency boilers consume less fuel, leading to lower energy bills. According to the Energy Saving Trust, replacing an old inefficient boiler with a new A-rated efficient combi boiler can save up to £380 a year. To maximize efficiency and minimize fuel costs, opt for an A-rated efficient boiler with 90%+ efficiency

Boiler Warranties

When purchasing a boiler, it’s crucial to consider the warranty period. A lengthy warranty covering manufacturing and material defects for both parts and labor can save you from expensive boiler insurance. Ensure that your boiler is maintained and inspected by a Gas Safe registered engineer annually to keep the warranty valid.
