Common Heat Pump Myths – Debunked

Heat pumps are quickly becoming one of the smartest low-carbon options for heating and cooling in the UK. But like many newer technologies, there are still plenty of myths that can cause uncertainty. 

At D-Mec Services, we want to clear up the confusion. We’ve taken a closer look at some of the most common misconceptions so you can separate fact from fiction and feel confident about whether a heat pump is right for your home.

Do Heat Pumps Work In Old Houses?

You don’t need to live in a brand-new, ultra-efficient house to benefit from a heat pump. While modern, well-insulated homes may see the biggest efficiency gains, plenty of older properties are great candidates too. In fact, the UK government’s Boiler Upgrade Scheme was designed with existing homes in mind. This offers grants to help households replace old boilers with cleaner, more efficient heat pump systems.

Do Heat Pumps Work When It’s Cold? 

Don’t worry about the cold! Modern heat pump systems are designed to keep working even when the temperature drops below freezing, with many models performing efficiently down to −15 °C. 

At D-Mec Services, we install advanced air-to-air heat pumps that provide reliable heating through the chilliest winters and refreshing cooling in the summer. This means you can enjoy comfort and peace of mind all year round.

Are Heat Pumps Noisy? 

Many people imagine heat pumps as loud and disruptive units, but that’s simply not the case. Modern air-to-air heat pumps typically produce only a low hum. This is similar to the background sound of a fridge or dishwasher, operating at around 40–60 decibels. With professional installation and careful siting from D-Mec Services, noise is kept to a minimum, so you can enjoy year-round comfort without any unwanted disruption.

Do Heat Pumps Require Constant Maintenance?

Heat Pumps require minimal maintenance. With just simple checks, filter cleaning and occasional servicing, they can keep running efficiently for decades. In fact, many systems last 20 years or more, far longer than the average boiler’s 10–15 year lifespan. 

For you, that means less hassle, fewer unexpected breakdowns and greater peace of mind over the long term.
