Underfloor Heating

A water underfloor heating system can sit beneath stone, tile, wooden or even carpeted surfaces. It offers a heating alternative to radiators in bathrooms, kitchens, an entire house – or simply a means to warm up a cold floor on an early morning in winter.

Water underfloor heating explained

underfloor-heatingWith a water-based underfloor heating system, a series of pipes connected to your boiler circulate warm water throughout the floor to heat the space. Alternatively, you can connect the water underfloor pipes to a solar water heating system. Because the heat emitted from an underfloor system is more evenly distributed than a single radiator, the system can use water at a lower temperature. So it’s a more efficient way of heating your home.

Underfloor heating is generally associated with stone or tiled floors, but you can fit it in a carpeted room – you’ll just need to ensure that the carpet and underlay isn’t so dense that it stops the heat moving upwards (a tog of no more than 1.5 is a general rule of thumb).

How water underfloor heating works

underfloor-heatingUnderfloor water heating works by connecting pipes laid under the floor to a manifold (essentially a central system to connect pipes together) and then to your heating system. It will also be fitted to a thermostat so that you can regulate the temperature.

The floor should be properly prepared and insulated to make the system work efficiently. There needs to be enough space to accommodate this and the piping, so we have to elevate the floor level.

Solar Photovoltaic (PV)

SolarGenerate cheap, green electricity from sunlight

Solar panel electricity systems, also known as solar photovoltaic (PV), capture the sun’s energy using photovoltaic cells. These cells don’t need direct sunlight to work – they can still generate some electricity on a cloudy day. The cells convert the sunlight into electricity, which can be used to run household appliances and lighting.

The benefits of solar electricity

  • Cut your electricity bills. Sunlight is free, so once you’ve paid for the initial installation, your electricity costs will be reduced.
  • Get paid for the electricity you generate. The UK government’s Feed-in Tariffs pay you for the electricity you generate, even if you use it.
  • Sell electricity back to the grid. If your system is producing more electricity than you need, you can sell the surplus back to the grid.
  • Cut your carbon footprint. Solar electricity is green renewable energy and doesn’t release any harmful carbon dioxide or other pollutants. A typical home solar PV system could save over a tonne of carbon dioxide per year – that’s more than 30 tonnes over its lifetime.

Cost, savings and maintenance

England and Wales

A 4kWp system can generate around 3,800 kilowatt hours of electricity a year – roughly equivalent to a typical household’s electricity needs. It will save nearly two tonnes of carbon dioxide every year.

  System Size Benefit Per Year Carbon Dioxide Per Year
Registered up until 31st March 2014 4kWp £785 1.8 tonnes
Registered on and from 1st April 2014 4kWp £770 1.8 tonnes

If your system is eligible for the Feed-in Tariff scheme it could generate savings and income of around £770 a year if you register before December 2015 (based on a 4kWp solar PV system eligible for a generation tariff of 13.52p/kWh). You will get paid for both the electricity you generate and use, and what you don’t use and export to the grid.

How do solar panels (PV) cells work?

PV cells are made from layers of semi-conducting material, usually silicon. When light shines on the cell it creates an electric field across the layers. The stronger the sunshine, the more electricity the solar panels can produce, but you’ll still be able to generate on a cloudy day.

The power of a PV cell is measured in kilowatts peak (kWp). That’s the rate at which it generates energy at peak performance in full direct sunlight during the summer. PV cells come in a variety of shapes and sizes. Most PV systems are made up of panels that fit on top of an existing roof, but you can also fit solar tiles so it can either be mounted on your roof or on the ground. Here at GE4L we install solar systems mainly in the south east of England which receives more sunlight than the rest of the country, offering the greatest returns.

Landlord Gas Safe Certificate

207837985bBy law, under the Gas Safety (Installation and Use) Regulations 1998, it’s your responsibility to get a gas safety certificate (CP12) every twelve months. You must get this from a Gas Safe Registered engineer for all pipe work, gas appliances and flues installed at your property.

GE4L specialise in providing a comprehensive service to landlords and often able to discount the service charge for landlords with multiple properties.

  • CP12 gas safety certifications for all tenanted properties from £60
  • Free annual reminders when safety checks expires.
  • Discounted rates for landlords with multiple properties

What you’ll get with a gas safety certificate (CP12):

  • Your gas appliances will be checked for gas tightness.
  • If test points are available, standing and working pressure will be tested.
  • Our Gas Safe engineer will check burner pressure and gas rate against the manufacturer’s data plate.
  • Checks will be carried out for the provision of all necessary ventilation.
  • Flue flow will be tested to make sure products of combustion are removed.
  • All flame failure devices will be checked for satisfactory operation.
  • Where appropriate checks will be made for physical stability, presence and effectiveness of stability brackets.
  • Investigations for any evidence of unsafe operation will be made and reported.

Without completing all of the above checks an appliance cannot be issued a gas safety certificate (CP12) and if there are any issues in your property we try to resolve it very same day.
