Case study: LG Monobloc system replaces gas boiler system

Stan Leatherbarrow is a Liverpudlian who has suffered from Crohn’s Disease for more than fifty years. His condition requires him to be treated with immune suppressant drugs and it’s vital for him to have a constant temperature in his home to help him maintain his health all year round.

Stan worked in the construction industry for more than fifty years and he has taken keeping his home in as near perfect condition for his illness as he can – it has to be said – with excellent outcomes. His three-bedroomed home has triple glazing and high levels of insulation to compliment his heating and hot water system.

A couple of years ago, Stan began researching alternatives to his gas fired boiler heating system. His experience was that he constantly had to switch the system on and off to get a constant temperature in the home and to provide the levels of comfort he needed. He began to research alternative heating options and was drawn towards air source heat pumps for a number of reasons including energy efficiency, energy costs and controllability.

He was concerned that he might struggle to find a renewables expert locally who could advise him but was recommended to talk to the team at Abacus Energy Solutions, just down the road from him in Bootle. Michael Platt from Abacus dropped in to see Stan and talk him through the options and to take a closer look at his home to see what the best solution might be for him: “Michael went the extra mile for me recognising my special needs, and at the survey, during the installation and vitally for me during the aftercare phase when I had any queries, he was always willing to pop in and talk me through things so I felt in complete control,” said Stan.

The installation was undertaken 18 months ago towards the end of 2020 and the team from Abacus were in and out within two days. They installed an LG R32 Therma V 12kW monobloc air-to-water heat pump along with a 180 LG pre-plumb hot water tank with a 50 litre buffer tank. The external unit is outside the house in the back garden and the tank is installed under the stairs. And it’s all been working like a dream. He has solar panels too which assist with domestic hot water in the summer and reduce his running costs for around six months of the year, but he has noticed virtually no difference in the domestic hot water supply from the old gas fired boiler system. Where he has noticed a difference is the heating. The heat pump keeps his heating at 21 degrees C each and every day of the year which is key to his comfort and helps control his Crohns Disease. He’s really enjoying the controllability of the new system and controls it from a remote controller that he keeps next to his armchair in the sitting room.

“Switching to the LG heat pump was the best decision I’ve made in recent years,” he says. “And the support I’ve had from Abacus has been absolutely first rate. They’ve been very good to me and I’m grateful for the excellent quality of their work and the levels of service they have given me since we decided this was the way forward for me. I’ve benefitted from the RHI as well – the Renewable Heat Incentive – which sees me get a cheque every three months for seven years based on the renewable energy generated by the system.”

Michael Platt from Abacus says this has been a really pleasurable project for the company: “Stan has been a delight to work with. He knew what he wanted, but needed help to find the right path forward for him with his health issues. And we’ve been able to hold his hand through the process and ensure he has the exact outcome he needed to be able to enjoy his days in comfort.”

The equipment installed in Stan’s home was supplied by LG distributor Bublshop based in Somerset. The company shares its 20+ years of renewables experience, and offers design, specification and installation advice to installers up and down the country.

A final word to Stan: “I’d recommend the air source heat pump from LG and certainly recommend the guys from Abacus if you’re in the Liverpool area – it’s a great combination and will provide high quality heating and hot water from a system that is well specified and perfectly installed. It has to be the future in a country that needs to become reliant on renewable heating to reduce the carbon emissions and get to Net Zero by 2050.”
