Air Source Heat Pumps
Air source heat pumps are an exceptionally clean and efficient source of producing heating and hot water for domestic properties and commercial sites.
Ground Source Heat Pumps
A ground source heat pump uses the constant latent geothermal heat in ground water to produce thermal energy ideal for heating and hot water. Ground source heat pumps use electricity and so for every 1kW of electricity used to operate the heat pumps, 3kW to 5kW of heat energy is produced and available for heating purposes.
Water Source Heat Pumps
With Water source heat pumps, groundwater is abstracted at ambient temperature from the ground via a submersible pump, passed through a plate heat exchanger coupled to the heat pump before being re-injected back into the ground or discharged at the surface.
Solar Photovoltaics (Solar PV)
GSM Ltd have been designing and installing both commercial and domestic Solar photovoltaic (solar PV) systems for over 10 years. We are well versed with multiple roof fixing solutions along with ground mounted arrays. We can provide a full planning permission service if required.
Battery Storage
If you are installing solar PV or a heat pump, we strongly recommend you consider battery storage at the same time.
Commercial Installations
GSM Limited was formed over 30 years ago to provide a mechanical, design and installation service second to none.
Underfloor Heating
GSM Ltd can offer the full turnkey package when it comes to heating installations.
Immersion Controllers
Smart Energy Diverter - eddiSmart energy immersion controllers are a simple and cost-effective way to capture some surplus electricity from onsite generation such as solar PV and divert the surplus to your immersion heater in your hot water cylinder. An average system coupled with a 4kw PV system will provide free hot water for 6 months of the year.
Smart Car Chargers
About zappi - The smart EV charger in a league of its ownZappi is a smart EV charger with a difference. Not only does it operate as a traditional EV charger, it can also charge your EV using 100% FREE energy generated from your Solar PV or wind generation.
Solar Edge Optimisers
More energy from the sunMore power = more savings on your electricity bill. In a PV system, each panel has an individual maximum power point. Differences between panels introduce power losses and can lead to under performance of the entire system over time.
Emergency call outs & Servicing
Annual Heat Pump ServicingOnce we have completed and handed over an installation, we will add you to our data base of installations. We will write to you once a year to inform you of what week we are carrying out servicing in your area.
