Please explain, using specific examples, how you are making genuine effort to reduce the environmental impact of your business and improve your sustainable practice?

As a company we only fit renewables. We’ve moved away from gas boilers completely and it would only ever be a very rare occasion that we would fit one of these. So, our environmental impact has been reduced through our work with our clients, moving them into sustainable systems. Me and the team design, supply and maintain renewable systems and we’ve definitely become experts in our field. This has helped to further improve our sustainable practice as we teach and consult customers on how to run their heating systems to get the most out of them and reduce their carbon emissions.

My main two goals out of any job are comfort and efficiency: comfort for the customer while maximising efficiency on the heat pumps. As a company we aim for 300/400% efficiency on our heat pump installs. As we keep the heat pumps running on a consistent low temperature, we can maximise comfort as well as ensure the longevity of the system.

How are you helping your customers become more sustainable and reduce their impact on the environment? Please provide at least one example.

Due to the fact that we only really install renewables, I think that one of the most important parts of our installations is teaching our customers how to properly use their systems to be as efficient as possible.

Other installers who install renewable systems will use with things like low loss headers and on/off thermostats which are all put in place to stop error codes. This actually means the system overrides customer errors so the customer never has to call back the installer. This not only makes the system more expensive for the customer, but it doesn’t maximise the efficiency of the system. The whole point of a heat pump is to save money for the customer and provide them with the most efficient system they can.

Taking this into consideration, I make sure I go through all the controls on the system with the client to teach them exactly how to use the system so it runs as efficiently as possible. I’ll also teach the customer about certain features like weather compensation.

A recent customer was having problems with his system that he was running in a church hall. The previous installer had it running on a COP of 2 and had put on/off controls on which meant it wasn’t maximising efficiency, costing the customer more money. So, I fixed the system removing the controls and it’s now running a COP of 3.5, teaching the customer exactly how to use it so he can be achieving this efficiency at all times.

Please provide details of a project you are proud of which made use of sustainable products and/or processes – what was the problem for the customer and how did you solve it? What products did you use and why? What was the end result?

A project that springs to mind for me is the work I did on a large 7 bed house. The property was a new build and didn’t have a gas supply which actually worked to my advantage as a predominantly renewable installer. I fitted 3km of underfloor heating with 2 Samsung heat pumps into a 200-litre buffer tank and 2,300 litre domestic water heating cylinders.

As the house was a new build, the main problem for the customer was working the heating system around more complicated builds like an indoor swimming pool and large staircase, which I did successfully. For this job I used a Samsung ASHP unit and Emmeti underfloor heating because they’re products I use regularly and know they’re incredibly reliable and durable. They have a great tech team behind them which means if any problems do arise, the customer has a team ready and available to help. I know the customer is going to get years of usage out of these products before they need replacing.

The end result for the customer was a neat yet intricate and detailed heating system that checked all of his boxes. I was able to successfully heat a very large house off a renewable heating system which will help to keep the house warm and keep the energy bills low in the long-term.
