Committed to building a sustainable future

From a simple boiler repair to a complete ground or air source heat pump system, South West Energy Services Ltd recognise the need to offer specialist expertise in delivering reliable, energy efficient and cost effective heating or cooling solutions.  We provide a turnkey package for all types of renewable energy and gas applications. We operate from our head office in Plymouth, Devon with 2 satellite offices in Clevedon, Somerset and Whitstable, Kent.

Not only are we capable of designing, specifying and installing advanced heating and cooling systems such as; under floor heating, radiators, fan coils and chilled beams but also provide our clients and end users with a nationwide support network.

We operate within residential, commercial and industrial sectors, building an extensive Ground & Air source heat pump installation portfolio and reputation.

If you have a project and require impartial advice on the suitability of renewable technologies including Solar Thermal, Air or Ground Source Heat Pumps or Solar PV please call our Technical team and speak to the experts.

With the growing demand and emphasis on green sustainable technologies, installing Heat Pumps, Biomass Boilers, Solar PV and Solar Thermal systems has never been more attractive and financially viable thanks to the Renewable Heat Incentive and the availability of tailored finance packages.

A+ Gas Boilers

We offer a range of SEDBUK A Rated, mains gas & LPG boilers from leading manufacturers. Supplied & installed prices for a 28kW combi start at £1950 inc VAT. Our gas appliance department also provides; service, breakdown and system upgrades for all types of of domestic and commercial mains Gas\LPG appliances.

Renewable Heat Incentive

See how the RHI can pay you back.

The Domestic and Commercial RHI is now in full swing with applicants receiving payments, covering 100% of the installation cost. The reduction in the Biomass tariff has allowed an increase in heat pump payments meaning installing a heat pump has never been so attractive

Environmental & financial benefits

Practical sustainable and renewable energy sources mean reductions in the use of fossil fuels through the use of proven technology.

Reduce your CO2 emissions: on average a heat pump could save around 1.8 tonnes of carbon dioxide every year when replacing an oil boiler.

  • Domestic heading accounts for over 35% of CO2 emissions in the UK.
  • Over 60% of the average homes CO2 emissions are created by the heating and hot water system.
  • Ground & Air source heat pumps are simple to install and are a direct replacement for existing oil and gas fired boilers.
  • Ground & Air source pumps are a proven technology which have been used all over the world as a primary domestic & commercial heat source for over 50 years.
  • Due to the high COP created by ground & air heat pump annual fuel bills can be reduced by as much as 50% when compared against Oil and LPG boilers.
  • With the RHI funding you can have your ground or air source heat pump system paid for within 7 years.
  • With Green Deal assistance a loan is available to pay for the upfront installation cost and when combined with the RHI you could have your system paid for in under 5 years!
  • RHI funding is now available for Commercial air source and ground source heat pump systems.
  • Call today to see how the RHI can benefit you or your business.

Are air source heat pumps noisy?

The simple answer is NO but what is noisy? Modern air source heat pumps are significantly quieter than units produced say 5 years ago. This is primarily due to advances in the development of fan technology and improved chassis design which reduces vibration. 99% of sound generated by an air source heat pump is the movement of air. The sound levels will vary depending on the ambient temperature. The colder it is outside the faster the fan spins and vice versa. In the middle of summer the fan may not even spin.

For the purposes of the MCS Planning Standards for air source heat pumps the back ground noise is assumed to be 40 dBa or lower. For compliance with planning regulations and permitted development rights the air source heat pump must be 42 dBa or lower from the assessment position.  The assessment position is the distance between the unit and a neighbouring property.

The positioning of the unit is critical to meeting the maximum sound levels. Obstacles such as walls and fences can increase the noise levels over the design conditions. A well designed air source heat pump system must allow for the displacement of the air. This not only reduces noise but also increases the efficiency of the heat pump.

When the noise exceeds the maximum permitted levels the unit can be installed in an acoustic enclosure or sitted far enough from the assessment position to meet the regulations. Heat pumps can be located up to 30m from the property before other design considerations are imposed.

To reduce sound levels  manufactures are encouraged to meet the standards set out by the Noise Abatement Society and  awarded the Quiet Note if the heat pump is within the standards. The Mitsubishi Ecodan was the first heat pump to be awarded the Quiet Note in the UK.
