A Home With a View That Could Not Be Enjoyed
Robert’s home sits 400 feet up on an exposed hillside northeast of Glasgow. “We are pretty exposed because we are at 400ft here… we get a lot of wild weather.”
When he and his family first moved in, they loved the potential of the site, but the house was facing the wrong way. “The house was the wrong way round… the living room was facing into the street and we had this beautiful view behind us.”
They reoriented the home, turning the back garden into a bright open living space with a large dining area. It should have become the centre of the home.
Instead, it was freezing.
“This particular room was always cool. The space was uncomfortable in the wintertime.”
Noisy fan radiators did little, and a log burner “made it livable” but sent most heat straight upstairs. Then came the breaking point.
“There was no heating upstairs because of a blockage… there was no science to the solution.”
“People generally said: let’s add more of these.”

“Outstanding Service from Aventus Eco Ltd – Highly Recommended! I had been struggling with unusually high electricity consumption—around 50 kWh per day—due to my air source heat pump system. Despite reaching out to multiple companies, including the original installer, no one was willing to help or even respond. That’s when I contacted Sean from Aventus Eco Ltd, and I’m so glad I did. Sean promptly visited my home, conducted a thorough evaluation of all relevant factors, and successfully identified the root cause of the issue. He didn’t stop there—he also provided a detailed report that I could share with the installer and even offered to assist further in resolving the problem. Sean’s professionalism, technical expertise, and willingness to go the extra mile truly set him apart. He is an absolute superstar, and I can’t recommend Aventus Eco Ltd highly enough for anyone facing similar challenges. ”
Searching for Answers and Finding Only Confusion
Robert works from home as a leadership coach and photographer. Comfort is essential to his daily routine.
“I was wearing one if not two fleeces quite often… people noticed online that I had three fleeces on when coaching them.”
He turned to the internet and quickly discovered a common problem.
“Searching the web is particularly difficult. There are too many vested interests and too many people with a point of view not based on science or professionalism.”
What he needed was independent, unbiased advice.
“I wanted to find an independent advisor who was not selling something and did not have a vested interest.”
That independent guidance helped him understand something no one had previously explained:
“The key piece of information was the size of radiators or emitters. It was so obvious, but no one had ever mentioned it.”
Once he understood heat loss, emitter sizing and comfort requirements, the next steps became clearer. The available grant support made a heat pump the logical long-term solution.

“Exactly as the process should be – right from start to finish Aventus Eco fitted solar panels, battery storage and an air-source heat pump, and the whole experience has been great. There was no hard sell from these guys, just lots of advice from people who clearly care about what they do, their business and their reputation. They took the time to get the design right for my home, including properly working out our power use and heat loss and sizing everything accordingly. ”
Choosing the Right Installer Based on Trust
The independent consultants recommended Aventus Eco. The moment Robert met Sean Hogan, something stood out.
“I felt I could trust them. They were trying to solve my problem.”
“He really came from a non biased point of view. He was trying to solve the problem. He understood that comfort was the first priority.”
For Robert, trust was central.
“Find somebody you can trust. If you do not trust somebody, do not go with them.”
He also appreciated Sean’s rare combination of technical and project management skill.
“You need both technical skill and organisation. If you have managed refits and refurb projects, you know what you are doing.”
This proved important once work began.

“Great experience using Aventus Eco to install a Heat pump at our terraced home. Very efficient from start to finish from Sean & co.; it took 4 days and we’re really happy with how it’s working. Sean also took time to talk us through how it all works and has been on hand to answer any question post-installation. Will be recommending them to friends and family.”
Installation Delivered With Care and Precision
Inviting installers into your home is emotional and often stressful.
“Your home is your safe space. I will not invite just anybody in.”
Robert was anxious about one part of the work: lifting the original wooden flooring upstairs to replace legacy microbore pipework.
What happened next surprised him.
“Sean did that part himself because he wanted to make sure it was done properly. It was done with the minimum of fuss and the minimum of disturbance.”
“He put everything back the way he found it.”
Sean maintained uncompromising standards throughout.
“If he did not like the way something was done, he would ask people to do it again, very respectfully, but it was non negotiable.”
From a leadership expert like Robert, this was high praise.
“That is what I look for in people who do work. They are in control, they are managing, they have taken responsibility.”
And the support continued long after installation.
“He still texts me to ask how things are going. If I forget how to operate something, he explains it to me.”
One line captures his view perfectly:
“One thing I can definitely say is Sean is not a boiler basher. He manages the whole project, the materials and the people.”
Your Home Deserves Care, Not Corners Cut
If the details matter to you — pipework, floors, radiators, finish — get a survey from a team that treats homes properly.

“Great experience from start to finish, excellent customer service and a job well done !”
Life After the Installation A Home Transformed
The impact of the retrofit is profound.
“The real difference now is this even temperature. I still have not got used to it even months down the line.”
Everyday experiences are transformed.
“When you get out of bed in the morning, it is not cold.”
“When you walk down the stairs to get your coffee, it is an even temperature.”
“You have not put on layers and layers of clothes.”
“I walk around the house with just a shirt on.”
His only humorous complaint:
“You have to water your plants a lot more.”
But the deeper change is about how he lives in the home.
“The danger when your house does not function is that you retreat into one space that you heat.”
“You want to be able to live in the space you have worked on.”
Now the entire home is usable, comfortable and stable.
“Having an evenly heated house in which every room is heated is a basic right for people. And it can be done if people do the job properly.”

“Outstanding service, difficult decision to make to change to air source heat pump especially give the level of misinformation. Sean/Aventus Eco were outstanding in helping me explore and decide that this was right solution. Additionally it involved full house re-plumb because of problems with the old system, This was handled sensitively and professionally by all the members of the team with Sean setting very high expectations for everyone. I had hesitated because of the level of disruption but in fact it all went very smoothly. Thank you Sean/Aventis Eco and your team. I have no hesitation in fully recommending Sean and Aventus Eco Ltd.”

“After calling many companies and having an electrician come and wrongly replace our fit meter, Sean could not have been more helpful. He took the time to help and explained everything so well despite it being a small job. He arranged for an electrician to come and checked in afterwards. I couldn't rate him higher; we are very grateful for his help.”
