With the cold weather, many homeowners are experiencing issues with efficiency of their air source heat pumps (ASHP) or ground source heat pumps (GSHP).

Some report that their systems are expensive to run or aren’t heating their homes properly. But why is this happening? In many cases, it’s due to poor installation. We believe the installers should be held responsible.

The Importance of Proper Installation

Heat pump systems are sold with promises of high efficiency and low running costs, often based on something called the Seasonal Coefficient of Performance (SCOP). This is a measure of how much heat your system can generate compared to the electricity it uses over a season. However, if your heat pump isn’t properly installed or designed, it won’t meet these performance levels. The result is higher costs and less comfort.

So, how do you ensure your system performs as expected? It’s important to work with an installer who can back up their claims with proof. At Custom Renewables, we hold ourselves accountable for each installation. We ensure every heat pump works as efficiently as possible.

Monitoring Your System’s Performance

One of the ways we ensure top performance is by offering Open Energy Monitoring for all customers. This monitoring system provides detailed information on how your heat pump is performing, including:

  • Energy Usage: How much electricity is being used compared to the heat generated.
  • Performance in Different Weather Conditions: How the system responds to outdoor temperatures.
  • SCOP and COP (Coefficient of Performance): This helps you understand how efficient your system is. It measures how much energy is being used versus how much heat is being produced.
  • Cycling Issues: We can see if the system is turning on and off too frequently, which can reduce efficiency and raise energy costs.
  • Temperature and Output: We track if the system is running at the right temperature and delivering the output it was designed for.

This data gives us insight into how well the system is performing. It also confirms whether any adjustments are needed to maximise efficiency.

Holding Installers Accountable

By monitoring the performance of our installations, we take responsibility for ensuring that every system we install operates at its best. This approach eliminates guesswork and ensures that our customers are getting the most out of their heat pumps.

Many installers still rely on outdated methods or “rules of thumb” to design and install heat pumps, but that’s not enough. With all the available information about system design, efficiency, and performance, the industry should be doing better. Our goal at Custom Renewables is to lead by example, delivering top-quality heat pump installations that are designed, monitored, and optimised for maximum efficiency.

The Bottom Line

A properly designed and installed heat pump should deliver on its promises—keeping your home warm without costing a fortune. By using advanced tools like Open Energy Monitoring and focusing on accountability, we ensure that every customer gets what they deserve: a high-performing, efficient heating system that works as promised.
