Hillingdon

The London Borough of Hillingdon is the westernmost borough in Greater London. It was formed in 1965 from the districts of Hayes and Harlington, Ruislip-Northwood, Uxbridge, and Yiewsley and West Drayton in the historic county of Middlesex. The borough covers a total area of 44.67 square miles. This makes it the second largest of the 32 London boroughs by area.

For administrative purposes, the borough is separated into North and South Hillingdon. The south of the borough's former strong connection with industry has diminished since the 1980s to be replaced by a predominantly residential suburban population; the north continues to be a consistently residential suburban area.

The borough's residential places expanded with the extension of the Metropolitan Railway from Harrow on the Hill to Uxbridge within the early twentieth century plus the gradual establishment of stops along the line, becoming called 'Metro-land'.

The population increased from 2001 to 2011 by 11.5 per cent, which is 4.4 per cent above the England and Wales mean of 7.1 per cent, making the borough a part of the fastest population-growth location. In this time, the number of households also increased by 3.3 per cent, with an average of 2.7 individuals per household.

The borough maintains over 200 green spaces, totalling about 1800 acres. As a lot of the area is within the Metropolitan Green Belt it was, in 2008, among the list of least densely populated of all the London boroughs; open spaces vary in size from the Colne Valley Regional Park to smaller sized gardens like Lake Farm Country Park. For all of your home upgrades, make certain that you use trustworthy pros in Hillingdon to make sure you get the top quality.

    FAQs

    How do I know if my gas boiler needs replacing?

    If your boiler is making strange noises or smells, or doesn’t seem to be working properly, it may need replacing. Boilers usually last about 10-15 years. Even if your boiler is working normally, it’s worth replacing when it gets this old. An annual check will establish if there are terminal problems with a boiler that cannot be fixed.

    How long does a boiler last?

    If you get the right size boiler for your home and you get it serviced regularly, your boiler could last up to 15 years. It may even last longer than this, but you’ll find that your boiler begins to become less efficient as it gets older. Also, as technology improves, a boiler older than 15 years may not be the most efficient one on the market.

    how does a gas boiler work?

    A boiler is simply the most important part of a central heating system as it generates the heat that warms up the home or property. Basically, the appliance or small furnace makes use of gas, LPG or oil in order to fuel its operation. However in the UK, most boilers are usually fuelled by natural gas which is supplied automatically from the national gas grid. And depending on how it operates, there are various types of boilers.

    Typically, a gas central heating boiler will have multiple pipes entering from underneath. While one pipe supplies the boiler with gas from the mains gas supply, another pipe allows cold water to enter the boiler to be heated, the last pipe then enables hot water to exit the boiler so it can be distributed around the home.

    ✓ There are fuel jets and heat exchangers inside the boiler. When the heating is turned on, a valve is opened to allow the mains supply gas to enter a sealed combustion chamber in the boiler. There are multiple little valves which permit the entry of the gas before being ignited by an electric ignition switch. These jets heat a metal component in the boiler known as a heat exchanger which works to transfer the heat to the cold water pipe and heat up the water.

    ✓ Once the water has been heated to the target temperature, it’s then pumped through a circuit of pipe which runs around your home by an electric pump.

    ✓ The heated water enter each radiator, is then transmitted via a closed loop and radiates heat into each room.

    ✓ Once done travelling through all radiators, the water then returns to the boiler at which it must have been cooled. Therefore, the boiler will have to reheat following the same process before circulating. The water can only be drained by a professional Gas Safe engineer

    Can I stay at home while my gas boiler is being replaced?

    When your boiler is being replaced you won’t have hot water or central heating. If you don’t mind this you can stay in your home, and use portable electric heaters if needed. Most installers undertake a power flush before installing a new boiler now and this can cause muck and debris from the pipework, so you may wish to get out of the way while this is happening!
