What Are Heat Loss Calculations?

Heat loss calculations are performed after a heat loss survey on a property and help understand the heating needs of the property by calculating the heat loss of the properties fabric. Heat loss calculations help an installer understand how much heat the building will loose through though the year.

 

This calculation is essential for installing the right size heat pump and getting the correct radiators sizing for the property. Having accurate heat loss calculations performed will ensure the efficiency of the system design and prolong the life of the product by making sure the system is not under or over sized putting strain on the system.

  • Complete room-by-room heat loss calculations for the full property 

  • A detailed heat loss summary

  • Required emitters with outputs at the required flow temperature

  • Details of the proposed equipment (such as SCoP, maximum output, etc)

  • MCS035 Model Performance Estimation

  • MCS020 Sound Calculations

  • MCS Compliance certificate

  • Recommended equipment

  • Any site-specific recommendations

As an optional extra, alongside the heat loss calculation, our design team can also provide a completed DNO application form with the relevant unit-specific technical information and assist you with the application process, saving you time with your pre-installation administration.

Understanding Radiator Sizing and Heat Loss Calculations in Greater London

As part of air source heat pump survey we also provide the full measurements of existing radiators and the room available for future changes. Apex Renewable Energy Surveys understand the importance of sizing radiators correctly with air source heat pumps and our professionally trained office staff specialise in heat loss calculations. This allows them to accurate calculate the correct radiators needed for the designed flow temperature of the ASHP that has been selected for the job.

Air Source Heat Pump Floor Plans in Greater London

Apex Renewable Energy Surveys will also provide a full floor plan after each survey, giving you a far easier job of planning your new potential installation. Not only does the floor plan make planning the installation run a lot smoother but it allows better communication between you and your customer. The customer will be able to understand which room you are discussing with them at any point, bedroom 1 and bedroom 2 can start to get confusing at some points in discussions with a floor plan guide this can happen much easier. This also allows installers to understand where the radiators are located and the basic information of the cylinder and current boiler locations.

Heat Loss Calculation Costs in Greater London

Heat loss calculations are very admin heavy and require a lot of knowledge and expertise this can often put up hurdles for new companies or growing companies. Apex Renewable Energy Surveys already have a fully professional established team with years of experience to perform heat loss calculations in a timely manor while making sure the accuracy is kept to high standard. We have built our costing system for heat loss calculations to allow companies a competitive price while also removing the leg work involved.

Increase Sale Conversion Rates in Greater London

Not only do Apex Renewable Energy Surveys provide professional and accurate surveys but we also get very positive reports from existing installers that we have increased sales conversion rates. This is due to many factors but the main factor for you as installer is that you can explain to your customer that a third party surveying company will be performing the survey. When explained properly this is a massive win for the customer as they will have the trust knowing that a fully experienced professional surveying company will be gathering the information and providing the system design giving them peace of mind that the system will be designed to the property and not to the installers benefit.

Importance of Heat Loss Calculations in Greater London

Heat loss calculations are crucial for the effective installation and operation of heat pumps in Greater London, ensuring energy efficiency, reduced carbon emissions, and cost savings. As heat pumps are increasingly promoted as a sustainable heating solution, accurate heat loss assessments play a significant role in their success, especially in a region like London with its diverse housing stock and urban challenges. Here are the key reasons why heat loss calculations are essential:

1. Accurate Sizing of the Heat Pump
Heat loss calculations ensure that the heat pump is properly sized for the property. This is vital in Greater London, where homes vary greatly in size and insulation quality. An undersized system won’t provide sufficient heating, while an oversized system will be inefficient and costly to run.


2. Energy Efficiency
Heat loss calculations help determine the specific heating requirements of a building, allowing for the installation of an appropriately sized heat pump. This reduces unnecessary energy consumption, leading to lower energy bills and more sustainable energy use.


3. Adapting to Local Climate
London has a relatively mild climate compared to other parts of the UK, but with cold winters and fluctuating weather patterns. Heat loss calculations account for these factors, ensuring the heat pump provides the right amount of heat in winter while being efficient during milder weather.


4. Optimizing System Efficiency
Proper heat loss calculations ensure that the heat pump operates within its ideal performance range. This prevents the system from overworking, reducing wear and tear, lowering operational costs, and extending the heat pump’s lifespan.


5. Addressing Diverse Housing Stock
London has a wide range of property types, from Victorian terraced houses to modern apartments. Heat loss calculations are crucial for adapting the heat pump system to the specific characteristics of each property, accounting for factors like insulation levels, window types, and building materials.


6. Reducing Carbon Emissions
Heat pumps are a key technology for reducing carbon emissions as they use renewable energy sources like air or ground heat. Accurate heat loss calculations ensure the system operates efficiently, maximizing its environmental benefits and contributing to London’s ambitious net-zero goals.


7. Cost Savings
Properly sizing a heat pump through heat loss calculations leads to lower running costs. This is especially important in Greater London, where energy prices and living costs are higher than in other regions. Homeowners can see substantial savings on their heating bills over time.


8. Improving Comfort
Heat loss calculations help ensure that the heat pump provides consistent, reliable heating throughout the property. This prevents cold spots or insufficient heating in certain areas, leading to a more comfortable living environment, particularly in older or poorly insulated buildings.


9. Ensuring Compliance with Building Regulations
In London, heat pump installations must comply with UK Building Regulations, which focus on energy efficiency and emissions reductions. Accurate heat loss calculations are often required to ensure the installation meets these standards, avoiding compliance issues or penalties.


10. Supporting London's Sustainability Goals
London has set ambitious targets to become a low-carbon city. By ensuring heat pumps operate efficiently through accurate heat loss calculations, homeowners contribute to broader sustainability efforts, reducing dependence on gas boilers and helping the city meet its climate goals.


11. Maximizing the Performance of Insulation Improvements
Many homes in London undergo retrofits to improve insulation, such as double glazing or external wall insulation. Heat loss calculations ensure that the heat pump installation is optimized in conjunction with these improvements, leading to even greater energy efficiency and cost savings.


12. Maximizing Government Incentives
The UK government provides financial incentives for installing heat pumps, such as the Boiler Upgrade Scheme (BUS). Accurate heat loss calculations are critical for qualifying for these schemes, ensuring the heat pump is properly sized and meets the required energy efficiency standards.


Conclusion
In Greater London, heat loss calculations are vital for the effective installation and operation of heat pumps. They ensure that the system is appropriately sized for local climate conditions and housing types, optimize energy efficiency, and help homeowners reduce both costs and carbon emissions. As London pushes toward its sustainability targets, accurate heat loss calculations are key to making heat pumps a viable and environmentally friendly heating solution.
