At Grant, we recognise the significance of selecting the ideal heating system for your new home. Our aim is to tailor a solution that meets your needs, ensuring enduring warmth and comfort for you and your family over the long term. Starting to plan your heating from the outset is very important as every home has different requirements and with a growing focus on sustainability, carbon reduction, and reducing environmental impact, incorporating renewable energy sources into your home heating design can help to future-proof your home.

What are heat loss calculations?  

Heat loss calculations are a very important part of designing highly efficient home heating systems. Grant’s heat loss calculations are in depth based on the level of detail and time taken to calculate the heat loss for each room in a property. 

Detailed room by room heat loss calculations provide accurate information in terms of the total heat loss in watts (W) of a property. These calculations include assessing the amount of heat that escapes from a building through its walls, windows, doors, roof, and other structural elements. This in turn enables the technical specialists at Grant to correctly size and specify the best suited Grant Aerona³ heat pump to heat the home. In addition, accurate heat loss calculations to provide the required outputs for the heat distribution within each individual room in the home. This ensures that the heating system can run at the lowest possible flow temperature and in turn helps to maximise efficiency and long-term cost savings for the homeowner. 

Why are heat loss calculations so important?  

Right-sized system: By accurately calculating heat loss, the Grant technical team can determine the appropriate size and capacity of the heating system needed to effectively heat your home. Undersized systems may struggle to maintain a comfortable temperature, while oversized systems can lead to inefficient operation and unnecessary energy expenses. This is extremely important when sizing a Grant Aerona³ R32 air source heat pump into your home. 

Energy efficiency: Understanding heat loss helps identify areas where energy is escaping from your home, such as through poorly insulated walls, windows, or doors. Addressing these areas can improve energy efficiency, reduce heating costs, and minimise environmental impact. 

Cost-effectiveness: Investing in a heating system that matches your home's heating requirements based on heat loss calculations can result in long-term cost savings. A properly sized system operates more efficiently, reducing energy consumption and lowering utility bills over time. 

Comfort: A heating system that aligns with your home's heat loss ensures consistent and comfortable indoor temperatures throughout the year. Proper insulation and ventilation also contribute to enhanced comfort by minimising drafts and maintaining optimal humidity levels. 

Environmental impact: Efficient heating systems consume less energy, resulting in reduced greenhouse gas emissions and environmental impact. By selecting a system tailored to your home's heat loss characteristics, you contribute to sustainability efforts and help mitigate climate change. 

System longevity: Over-sizing or under-sizing a heating system can lead to premature wear and tear, reducing its lifespan and increasing maintenance costs. By accurately assessing heat loss, you can prolong the life of your heating equipment and minimize the need for repairs or replacements.
