Renewable Heat Sources

What we Do

At Calmec, we understand the burgeoning need for sustainable and cost-effective heating solutions in both residential and commercial buildings.

As an industry leader in renewable energy installation, we’re at the forefront of air-source heat pump installations and ground-source heat pump installations – highly efficient systems that are transforming how we heat our buildings.

Easy to install and capable of significantly reducing heating bills, these systems represent the future of the renewable sector.

What is a ground-source heat pump installation?

Calmec specialise in ground-source heat pump installations.

A ground-source heat pump harnesses the relatively stable and consistent heat stored in the ground to provide heating, cooling, and hot water for residential and commercial buildings.

There are many benefits to opting for a ground-source heat pump to warm your building.

This heat source can be more efficient than many other heating systems because it uses stable ground temperatures, which remain relatively constant throughout the year. This can also mean that they significantly reduce energy bills, especially in well-insulated buildings, as they require less electricity to extract heat from the ground compared to generating heat from traditional fuel sources.

Ground-source heat pump installations are cost-effective because these systems typically have a longer life span than conventional heating systems. The ground loops can last for decades, and the heat pump units can last for 20-25 years or more with proper maintenance. So, while there will be an upfront cost for installation, the cost of running and maintaining the system will stay relatively low.

Additionally, these systems can provide both heating and cooling, and some systems are also designed to supply hot water, offering a comprehensive solution for a building’s HVAC needs.

With sustainability and green practices becoming more and more prevalent in business, the biggest benefit of a ground-source heat pump installation is that these systems are environmentally friendly, producing fewer greenhouse gas emissions compared to fossil fuel-based heating systems due to their use of renewable energy from the ground.

We are experts in installing ground-source heat pumps, having gained knowledge from our many years of experience.

What is an air-source heat pump installation?

When a ground-source heat pump installation is not suitable, an air-source heat pump installation might work.

An air-source heat pump operates by transferring heat between the outdoor and indoor air to provide heating, cooling, and sometimes hot water for buildings.

Air-source heat pumps are generally easier and less expensive to install compared to ground-source heat pumps because they do not require extensive ground loop installations. This makes them a more cost-effective option for some buildings.

They are also very adaptable, so they are suitable for a wide range of climates. These systems can extract heat from the outdoor air even in colder temperatures, making them viable for various regions.

We often find that air-source heat pumps are a suitable choice for properties with limited outdoor space because they typically have smaller outdoor units compared to ground-source heat pumps.

Due to the fact that they draw heat from the surrounding air, air-source heat pump installations may not be as efficient as ground-source heat pump installations in extremely cold temperatures. However, they are still more energy-efficient than many traditional heating systems, contributing to reduced energy consumption and lower utility bills.

Our teams have installed many air-source heat pumps over their years of experience and provide an efficient and knowledgeable service. Speak to one of our team members to learn more about whether an air-source heat pump is suitable for you and how you might benefit from one.

Renewable heat Sources FAQS

At Calmec, we are able to install both air source heat pumps and ground source heat pumps for residential and commercial buildings.

While ground source heat pumps are incredibly environmentally friendly at keeping your building at optimal temperature all year round, there are a few drawbacks to them.  

Firstly, they can be expensive to install because their installation process is complex and can require a lot of labour.  

Additionally, due to their set-up, they aren’t often suitable for residential properties, or properties with small outdoor areas.  

If you are considering a ground source heat pump, we recommend you speak with one of our experts to learn more about the systems. Call us on 01202 070 280 

Therefore, you need a professional team to design and install a system for you.

Air source heat pumps are a great renewable energy source for many properties, however, there are a few considerations that need to be thought about before installing one of these systems.  

Firstly, they include a bix that can not be covered to sit outside your property, meaning there is a visible element to the system.  

Additionally, for older houses, or poorly insulated houses, these systems aren’t very efficient and are likely to cost a lot to run.  

Speak to a member of our team to learn more about air source heat pumps and discuss if this renewable energy system is suitable for your home.  

Both air source and ground-source heat pumps have many advantages and things to consider. Each will perform better in different situations, therefore to understand which might be the better option for you and your aims, we recommend calling our team of specialists. 

We will discuss where you are looking to install the renewable heat system and your energy consumption before talking you through your options and our recommendations. Call us on 01202 070 280, or complete our contact form and we will get back to you as soon as possible.  

Both air source heat pumps and ground source heat pumps are known for their energy efficiency. While they do use electricity to power their operations, they provide several units of heat for every unit of electricity consumed. Ground source heat pumps, in particular, tend to be even more efficient because they extract heat from the ground or water, which maintains a more stable temperature compared to outdoor air. So, while they use electricity, they’re considered energy-efficient alternatives to traditional heating systems.
