Efficiency and Renewable Energy Installed

Mantis Energy - Case Studies - Insulation, Lighting, Heating, Solar Panels, Heat Pumps

Challenge
A 1923 uninsulated and single glazed property operating with an old gas boiler resulting in very high energy bills.

Solution
A complete energy retrofit was undertaken to modernise the property and use energy as efficiently as possible utilising available government incentives such as the Feed in Tarriff (FiT) and Renewable Heat Incentive (RHI).

Benefits
Mantis Energy provided a performance and economic evaluation to select the most cost effective options, obtaining competitive quotes, discussing with the clients and arranging / supervising all installations.

Next Steps
A key advantage of the installed systems is the level of monitoring, automation and integration. The heating and hot water are controlled by usage and activity in the house and all appliances are monitored for energy use.

MANTIS ENERGY SERVICES PROVIDED: Energy, Efficiency & Renewable Assessment

Efficiency and Renewable Energy Recommended

Mantis Energy - Case Studies - Insulation, Lighting, Heating, Solar Panels, Heat Pumps

Challenge
The clients property is a 1970 EPC F property operating with an old gas boiler. The energy bills for the property are very high primarily due to heating inefficiency and poor floor insulation.

Solution
A combined energy usage, efficiency and renewable assessment was undertaken to consider all feasible options, performance and economics.

Integrated Assessment
Mantis Energy assessed combined efficiency measures and renewable technology such as floor / wall / loft insulation, underfloor heating, solar panels and an air source heat pump to provide an integrated energy benefit.

Next Steps
The client now has a much greater understanding of the improvement potential of the house. They can review all recommended measures and select which areas they would like to retrofit with the help of Mantis Energy or by themselves.

MANTIS ENERGY SERVICES PROVIDED: Energy, Efficiency & Renewable Assessment / Initial Project Management

Efficiency and Renewable Energy Recommended

Mantis Energy - Case Studies - Insulation, Lighting, Heating, Solar Panels, Heat Pumps

Challenge
The clients property is a converted sandstone barn with EPC E operating with an old gas boiler. The energy bills for the property are very high primarily due to heating costs with no external wall insulation and inefficient heat distribution (radiators).

Solution
A combined energy usage, efficiency and renewable assessment was undertaken as well as providing a full list of quotes for each efficiency and renewable option.

Initial Project Management
The initial project management service considered the clients budget, goals and timeline into a project start package. Mantis Energy provided 3x independent quotes for each retrofit option and pre-qualified all required suppliers / installers

Next Steps
The client is now able to start work immediately with quotes ready to be signed and installation work able to be planned. The client can now proceed with the retrofit work with the help of Mantis Energy or by themselves.
