Why opt for a Heat Pump?

Heat pumps are complex systems with many moving parts–and at Invictus Mech, we’ve got all of them covered. From installation to maintenance and repair, we can keep your pumps in peak shape all year long.

Although the investment is higher, the technology creates far less carbon emissions and is more efficient and affordable to run than traditional heating systems like gas, LPG and oil-fired boilers. In recent years demand for pumps has only increased, driven by a nationwide imperative to reduce carbon emissions.

At Invictus Mechanical Ltd we install and service heat pumps for both commercial and residential properties operating in the Bristol and Bath region, including Industrial-Grade Systems in Manufacturing Plants and Factories.

What are Heat Pumps?

Heat pumps are basically air conditioners that pump out warm air instead of cold. These units function by taking heat from an external source, like air or the ground. However, unlike air conditioners, heat pumps can work both ways, pushing heat into a building during colder seasons, or pulling it out during particularly hot days or in warmer environments.

Heat pumps are made of 5 vital components: the refrigerant, condenser, expansion valve, evaporator, and compressor. Refrigerant flows through the system and acts as a vehicle for heat, pumped by the compressor. It passes through the condenser, where it absorbs heat. The evaporator coil then releases this heat inside the unit, warming air, which is then pushed out into the room.

Types of Heat Pump

Geothermal Pumps

Geothermal pumps, as the name suggests, takes heat from the Earth. These systems are generally more powerful, efficient, and reliable than air source counterparts; underground heat energy is more consistent than ambient air, which is more thermally volatile due to changing seasons. Some ground-based systems can even pull enough energy to double as a water heater.

The main disadvantage of using geothermal pumps are higher upfront costs. Geothermal pumps are sophisticated systems–utility providers typically have to drill anywhere from 4 to 100 metres underground, requiring specialised tools for proper installation.

Air Source Pumps

Air source pumps are smaller, sleeker machines that are usually installed outside of buildings and homes. These units are the cheapest type of air pumps, and so are popular with homeowners.

The tradeoff of convenience is inefficiency. Most air source units are only half as efficient as ground-based pumps. Located outside and exposed to the elements, they are also more prone to damage and require frequent maintenance.

Importance of Heat Pumps in Commercial Spaces

Fosters an environment for productivity

Thermal comfort should be given in any workplace and is actually required by law. However, in reality, a great number of uncomfortable employees waste collectively 2% of office hours a day each day are wasted as a result of poor temperature control at work, costing the economy some £13 billion a year. An efficient heat pump can maintain a steady temperature, reducing your energy bills, and increasing workforce productivity.

Helps you stay compliant and gain government support

Heat pumps are the standard for many developed countries like Sweden, Switzerland, Canada, and the United States. In an effort to bring the UK up to standard, the government offers several programmes to encourage the use of these energy-saving systems. For instance, the Renewable Heat Initiative offers financial support to owners of heat pumps.

Prevents costly replacements

Heat pumps are highly custom systems. There’s no one out-of-the-box solution, which makes self-installation incredibly difficult, it not impossible. If you’re installing a geothermal pump system, you have to consider space, soil conditions, and type of pipes that will suit the geography of the site. For air source units, you have to factor in a building’s existing network of vents, as well where to best place the pump to minimise exposure. Amateur installers may miss these factors, leading to installing pumps poorly fit for your needs.

An Exemplary Service that puts Safety First

Poorly installed heat pumps can also promote the growth of dangerous mould, where moist air and damp spaces meet. Improperly installed, your heating system may unknowingly be turning your site into a lush breeding ground for harmful pathogens.

This is why we take safety very seriously when it comes to heat pump installation and servicing. Our team of REFCOM registered heating engineers provide end to end support and our work is measured against the most stringent criteria for quality and safety, and certified by OFTEC, Gas Safe and Safe Contractor standards.
