Understanding Boiler Types: Compare And Choose Wisely

There are three main boiler types to consider when upgrading or replacing your heating system: combi boilers, system boilers, and conventional boilers. Each type has its own benefits and is suited to different home sizes, water pressure levels, and hot water demands.

1. Combi Boiler Benefits

A combi boiler supplies hot water directly from the mains and provides heating via one compact unit. This eliminates the need for a separate water tank or cylinder, making it ideal for smaller homes or where space is limited. They are highly efficient, often achieving an AFUE rating of 90% or above, with lower installation and running costs. They work best in properties with one bathroom and up to 15 radiators.

2. System Boiler Advantages

A system boiler stores hot water in a cylinder but does not need a cold water tank in the loft. It is perfect for medium to large homes with higher hot water demand, as it can supply more than one tap or shower simultaneously. System boilers are easier to install than older conventional models because they contain most components—such as pumps and valves—within the unit.

3. Conventional Boiler Pros And Cons

Commonly called regular boilers, conventional boilers use both a cold water storage tank and a hot water cylinder. They are able to serve homes with low mains water pressure or properties where hot water supply must cover many outlets at the same time. While they take up more space and require extra installation time, they can be compatible with renewable energy solutions.

 

Why Condensing Boilers Are Now Mandatory

Modern condensing boilers are legally required for all new UK installations due to their ability to recover heat from exhaust gases. This makes them more efficient and environmentally friendly compared to non-condensing models. An A-rated efficiency condensing boiler can significantly reduce heating costs and lower your home’s carbon footprint. 

 

Calculating Your Heating Needs: Output And Heat Loss

To get the best performance, your boiler must be the right size for your home. This involves a professional heat loss calculation and checking your property's boiler output kW requirements.

Using A Boiler Sizing Guide

Choosing the right size is about balance—an undersized boiler will struggle, while an oversized one will waste energy. Our engineers follow a precise boiler sizing guide to match your needs, taking into account insulation levels, property size, number of bathrooms, and radiator count.

Smart Boiler Controls For Efficiency
