Traditional Welsh cottage turns to heat pump for reduced carbon footprint

Daikin Altherma 3 H HT heat pump installed in 2-bed rural dwelling replacing oil-fired boiler resulting in much reduced carbon footprint and year round comfort



In the early days of Covid, accountant Susan Holt and her husband Philip made the decision to move away from the bustling town of Stockport in Greater Manchester to Willow Cottage, a traditional Welsh long cottage set on a two-acre smallholding in the rural village of Trefonen, Shropshire.

The cottage originally featured just one room downstairs and two above, but had been extended with a front porch, a kitchen, scullery, shower/toilet and study, all in a single-storey addition to the rear of the property. The upstairs had also been reconfigured with two bedrooms and a bathroom, while a studio had been added at one end of the building, and a boiler room at the other.

When the Holts moved into their lovely new home, they realised that the oil-fired boiler – installed by the previous owners 20 years previously – was on its last legs. The boiler eventually broke down at the worst possible time, over Christmas, leaving the couple with a decision to make.



Rather than making a ‘distress purchase’ of a replacement oil boiler, the Holts decided it was time for a change. They had already discussed moving to a renewable energy solution, so when their boiler gave up the ghost, they immediately contacted Air2Heat Ltd, a local provider of sustainable heating systems.

Their local installer visited the property and recommended the Daikin Altherma 3 H HT, an air-to-water heat pump that runs on the industry-leading R 32 refrigerant for greater energy efficiency and even lower CO2 emissions. One of our best-selling models, the Altherma 3 H HT delivers heating and hot water all year round.

When it came to installation, the Quiet Mark-certified outdoor unit was positioned outside the boiler room, which now houses the indoor floor standing unit which is connected to a 180-litre hot water cylinder. “We were very lucky to have the boiler room,” says Susan, “without it we would have struggled to fit an indoor unit and cylinder into the cottage.”


As with all home energy upgrades that involve installing a heat pump, the first result was that Willow Cottage now enjoys a much-reduced carbon footprint. The Daikin Altherma 3 H HT provides heating and hot water by extracting energy from a renewable source (air) so it is one of the most energy-efficient ways you can heat your home.

A further benefit is that the R 32 refrigerant in the Altherma 3 H HT unit has a much lower global warming potential (GWP) than earlier refrigerant gases, minimising the effect of the refrigeration system on the planet – another significant environmental benefit.

Meanwhile, thanks to their switch to a sustainable heat pump system, the Holts can also look forward to consistent, reliable comfort all year round – one of the main sources of satisfaction for new heat pump customers.


We were already thinking about an air source heat pump as part of the next stage of our renovations, so when the boiler broke down – it was time to make the change. The boiler room is nice and cosy, that’s why the builders like to huddle there during the day when they’re working on site. And we only notice the heat pump when it’s really cold – normally you can’t hear it from indoors
