A heat loss survey is an essential step when designing or upgrading a heating system. It calculates how much heat each room in your property loses, allowing your heating system to be sized correctly and perform efficiently.

​

 

What Is a Heat Loss Survey?

​

A heat loss survey measures how much heat escapes from different areas of a property, including walls, windows, floors, ceilings, and ventilation.

​

By calculating these heat losses, we can determine the exact heating requirements for each room, ensuring radiators, underfloor heating, or other heating systems are correctly sized.

​

This helps prevent systems that are underpowered or oversized, both of which can reduce efficiency and comfort.

​

Why Heat Loss Calculations Matter

​

A properly designed heating system offers several important benefits:

​

⚙ Improved heating efficiency
⚙ Consistent and comfortable temperatures
⚙Reduced energy waste and running costs
⚙ Correctly sized heating systems

 

Without a proper heat loss survey, heating systems are often sized using rough estimates, which can lead to poor performance and higher energy consumption.

 

When Is a Heat Loss Survey Recommended?

​

Heat loss surveys are particularly useful when:

​

• Installing a new heating system or boiler

• Designing underfloor heating systems

• Installing heat pumps

• Renovating or extending a property

• Improving the efficiency of an existing heating system

​

Accurate calculations ensure the heating system is designed specifically for the building.

​

Detailed Room-by-Room Assessment

​

During a heat loss survey, our engineers assess several factors including:

​

• Room size and layout

• Insulation levels

• Window and door types

• Wall and floor construction

• Ventilation and air movement

​

Using this information, we calculate the heat demand for each room, allowing the heating system to be designed correctly.
