1, Home Owners & Landlords
The device can be fitted into a rented home but you would need permission from the landlord. This device can be easily removed by an electrician and taken with you if you decide to move home.
I live in a grade 2 listed building. Does the installation include anything being fixed outside or any alterations at all being made? If so it could be a problem.
The BlueGreen Power Saver saves money with most, but not all, appliances. Thermostatically controlled resistive loads use less power at reduced voltage but operate for longer meaning savings are zero. Such appliances last longer when operated at lower voltage. Switch mode power supplies (SMPS) are common in many electronic products and savings here are low, perhaps 1% to 5% for a 10% reduction in voltage. However these devices are generally relatively small loads such as entertainment systems, phone chargers and IT equipment. The big savings come in refrigeration, motors and pumps. Not only are savings often over 10% but these appliances enjoy significantly longer life. Tests have shown that a typical home will see overall electrical energy reduction of between 6 and 12%.
The device regulates the voltage in the home to a steady value, typically 220V. The UK average supply is 245V and most appliances use less energy at the lower voltage. All appliances must be CE-marked and this means they will operate normally at the lower voltage. With a BlueGreen installed, your electricity bill will be between 6 and 12% lower and your appliances and light bulbs will last longer.
Between 3-5 years depending on the size of your bill, the level of supplied voltage and the types of appliances you have. We offer a no obligation in-house suitability survey before any installation. We can give a better indication after a short telephone conversation with you. This is followed up (if we both agree) with the suitability survey. Request your Short Informal Call here…
Electrical testing of the installation must be completed in accordance with current legislation, guidance or codes of practice. In the UK the BS7671 (IET Wiring Regulations) 17th Edition is the current standard. An electrical installation certificate will be provided by the electrician.
The BlueGreen will regulate a constant load of up to 5kW, and a load of up to 8kW for a limited period. If overloaded for extended periods, the device will enter bypass mode. You won’t lose power to the property but your appliances will receive the unregulated supply voltage until the load has reduced. In most cases the BlueGreen will progressively adjust the load voltage when changing operating mode.
In the unlikely event of a fault, Bristol BlueGreen will provide a replacement unit free of charge in the first 12 months, or the first 36 months if the customer has completed and returned the warranty card. The warranty is only valid if the unit has been installed and operated in accordance with the installation manual. Full details of the warranty can be found here.
Will we save money on heating devices such as an electric shower, underfloor heating or kettle if we fit a BlueGreen power saver?
There will be no savings on thermostatically controlled devices. At lower voltages they take marginally longer to get to temperature. But once at temperature their thermostats ensure that cooking times etc remain unaffected. These devices typically count for a quarter of a home’s electrical consumption.
