Renewable Heating

Advancements in technology over recent years have meant that we can all now look to use greener and more efficient ways to heat our homes.  

For a number years SA Technical Services have worked with leading manufacturers of green and renewable domestic heating and cooling systems. We have always been huge advocates of moving towards solutions that don't have a detrimental impact on our environment.

We understand it's almost impossible and pretty impractical for most people to erect a wind farm in their back garden, but there are a number of solutions that offer both greener energy and more efficient solutions to lower monthly energy bills.

Depending on your circumstances, situation and property type there are a number of options you can explore. At SA Technical Services we are proud to provide the complete solution. From having the initial discussion to the ongoing maintenance, service and repairs. Our aim is to offer a seamless solution for all your heating requirements.

Air  Source Heat Pump Systems

How does it work?

In domestic heating use, an ASHP absorbs heat from outside air and releases it inside the building, as hot air, hot water-filled radiators, underfloor heating or a domestic hot water supply. The same system can often do the reverse in summer, cooling the inside of the house. An ASHP can offer a full central heating solution and domestic hot water up to 80 °C.

The main components.

  • An outdoor heat exchanger coil, which extracts heat from ambient air

  • An indoor heat exchanger coil, which transfers the heat into hot air ducts, an indoor heating system such as water filled radiators or underfloor circuits and a domestic hot water tank.

Air source heat pumps can provide fairly low-cost space heating. A high efficiency heat pump can provide up to four times as much heat as an electric resistance heater using the same amount of electricity.


The lifetime cost of an air source heat pump will be affected by the price of electricity compared to gas.

Burning gas or oil emits carbon dioxide and nitrogen dioxide, which can be harmful to both our health and the environment. An air source heat pump issues no carbon dioxide, nitrogen oxide or any other kind of gas. It uses a small amount of electricity to transfer a large amount of heat: the electricity may be from a renewable source, or it may be generated from power stations which burn fossil fuel. Air source heat pumps can last for over 20 years with comparably low maintenance requirements.

Ground Source Heat Pump Systems

A geothermal heat pump or ground source heat pump is a central heating or cooling system that transfers heat to or from the ground, often through a vapor-compression refrigeration cycle.

With the growth in energy efficiency and demands to reduce our environmental impact, we have seen Ground Source Heating Systems become very popular in recent years, mainly due to the benefits they offer verses traditional boiler system. They are one of the most cost-effective renewable energy source available when it comes to heating or cooling the air throughout your home, as well as producing hot water all year round.

The system uses the earth as its heat source in the winter months and takes advantage of the moderate and stable temperatures throughout the year.  

Setup costs may be higher than conventional boiler systems, but the difference is estimated to be returned usually in energy savings over 7 to 10 years.

Underfloor Heating

How does it work?


Modern underfloor heating systems use either electrical resistance elements ("electric systems") or fluid flowing in pipes ("hydronic systems") to heat the floor. In both cases, they offer more efficient ways of heating the space in your home.

Why choose Underfloor Heating?


Modern buildings are often designed to utilise the most efficient ways of delivering heat to your home. This is part of the energy efficiency planning and vital to all new build applications. In older homes, apart from the obvious benefits of cheaper fuel bills, underfloor heating allows for a cleaner room design. It's a great way to maximise your space without having the compromise of pipes and radiators.
