experience with the Global Energy Systems.

I want to say a HUGE thank you to the team for the excellent work installing my new air source heat pump this week.
I was particularly impressed by how smoothly the whole process went and ultimately how quickly the team took out my old system and got the new one running. I was never for one day without hot water. And it was very thoughtful indeed to provide me with heaters for the few days of no heat.
The professionalism of the team was incredibly tidy and at the end of each day my home was made tidy and ready for the next day. They kept me informed throughout the process so I always knew what the next stage was. It made the transition much easier from day to day. Where possible they found solutions to hiding pipe work for which I am very grateful.
It’s a relief to have a reliable heating and water system without the regular breakdown of my old boiler. I can certainly recommend your company to anyone thinking of a new heat pump system.
The process took 4 days to complete and 1 day to commission it and it was a pleasure to have them in my home. Global will be very happy with the way they represent your company in such a positive way.
I will miss the lads cheery nature and singing! I would be grateful if you can make them aware of this feedback
Best Wishes to all at Global Energy

“3 Winters, A very large old house and nothing to complain about Have had the system for over 2 years and it has surpassed our expectations magnificently.
It’s a Victorian house with no underfloor heating, but this hasn’t proved to be a problem.
Running costs are cheaper than expected.
Because temperature in radiators is lower than oil/gas, it takes a bit longer to get up to your requirements, but that’s not a problem – get it to come on earlier!
Global Energy is a superb company to deal with, and they been very quick, friendly and efficient at dealing with the couple of minor teething problems at the beginning.
I’ve been trying to spread the word about Air Source Heat Pumps and Global Energy ever since it’s been up and running”

“I chose Global Energy Systems to install my ASHP because they were efficient, British and I had confidence in the representative who quoted on the installation. Their customer service was excellent and the representative visited us and discussed the options available to us in full. Although our product is at the expensive end of what is available, this was made clear to us and we looked at cheaper models prior to making the decision. So far our ASHP is surpassing expectations, providing us with endless hot water and reliable heat – even in freezing temperatures!”

Tanya Williams

“I first came across Global Energy at a local renovation exhibition. You could tell that they came across as really organised and knew what they were talking about, which made them stand out from anybody else we’d talked to.Overall very very good, cant be more clear really – they were excellent. The guy who came out came across as very capable from first meeting (talked about project with knowledge), manufactured in UK, same people throughout the whole installation process meaning there was continuity and good communication. They’re a small enough installer to deliver service without hiccups. They spent a good amount of time showing how to use it and then gave me a phone helpline number, meaning I feel well supported.”

P Jones

“To start with, I liked the system that they had and went on from their really. The installation went fine and i’m really happy with it. The engineer couldn’t have been any better, he definitely knew what he was talking about, what he was doing, the best way to install it and how I can get the best from my system. He explained that the Caernarfon would have the best compatibility for the position and size of the house. I’ve only had it 6 weeks but so far it seems okay. What i like is that Global Energy Systems are just at the end of the phone which is great, they are very helpful.”

“Global Energy stood out for me due to the design of their pumps. My pump is green, which looks great on the farm, and it is also designed in the UK for UK climate. It provides not only hot water but also underfloor heating, no need for a boiler inside – making it a space saver. The installer was very good and they all know what they are talking about. Afterwards they continue to look after the system and keep an eye on it from their office to check it’s all working properly”
