Air Source Heat Pumps

What is an air source heat pump?

Air source Heat Pumps are a way of providing you with heating and hot water in one of the most environmentally friendly ways possible; by using air as its fuel source! Imagine it to be like a fridge, a fridge extracts the heat from the inside to make it cooler. An ASHP works in the opposite way; by taking heat from outside to make it warmer! It doesn't just need a warm day though, your ASHP unit can even manage to extract heat from the air in temperatures as low as -15°C !

Still don't get it?

Don't worry! hopefully this diagram below can help you understand the cycle of an ASHP. You can always read more information about this on our > Heat Pump < page.

Repairing an ASHP unit in Fowey

This week we were called out to Fowey with complaints that although the Air Source Heat Pump was running as it should be, it wasn't actually producing any heating or hot water upon closer inspection it was clear to see that the soft start unit inside the ASHP was not only not working, but had completely burnt out! After speaking to the fantastic support team at Grant Engineering, we were quickly able to replace the burnt out unit for a happy new one!

Above you can see the damage to the old soft start unit that was simply too old and tired to work.
Below you can see the before and after pictures of the unit in its correct placement in the ASHP.

However the system still wasn't perfect...

We also discovered that the soft start unit wasn't the only issue, but also the immersion timer no longer worked either. We were able to promptly replace this for a new timer and the system was once again working as it should be!
