What is an Air Source Heat Pump?
Air Source Heat Pumps are the most common type of heat pumps, using electricity to pull heat from the outside air for your home’s hot water and central heating. Their specialised refrigerant efficiently absorbs warmth and converts it into a gas, even at temperatures below -50°C.
The heated gas is then compressed, transferring warmth into your central heating and hot water systems. Additionally, any surplus hot water can be stored in a hot water cylinder, making ASHPs a truly sustainable option that can also help you cut down on your energy bills.
With grants of up to £7,500 available via the Home Energy Scotland Grant and Loan Scheme, plus an optional £7,500 interest-free loan, now’s the ideal time to invest in clean heating for your home in St Andrews. Don’t delay – get your free ASHP quote from I.S Plumbing & Heating today!

ASHPs vs Boilers: How Do They Compare?
Boilers have been heating UK homes for decades. But with recent skyrocketing gas prices and expected future drops in electricity rates, Air Source Heat Pumps are quickly becoming a homeowner favourite. In large part, this is due to their amazing efficiency.
Here’s the deal:
Air Source Heat Pumps boast an incredible efficiency of around 300%. That means for every £1 you spend, you are getting £3 worth of electricity back. In contrast, all new UK boilers are around 90% efficient, losing about 10% of electricity, or 10p for every £1. What’s worse, older boilers can be only 70% efficient, meaning a significant 30% loss, or 30p per £1. So, it should come as no surprise that Air Source Heat Pumps in St Andrews and throughout Scotland are gaining in popularity.
