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.

Yes – solar thermal can be used for central heating. Solar thermal panels work by collecting heat from the sun, either through evacuated tubes or flat plate collectors, and transferring that to a heat transfer liquid that heats your hot water. This can then be used to preheat your central heating.

You’ll need a hot water cylinder to store the water that your solar thermal panels heat up. It’s likely that you’ll need an immersion heater or boiler to heat the water further so you can use it for your central heating, and as a back-up during the longest winter months since the solar panels won’t be able to generate as much heat.

In our opinion, it’s best to use your solar thermal panels for hot water rather than your central heating. That’s because you use hot water all year round, whereas you probably won’t have your central heating on in the spring and summer, when the panels can generate the most heat. For central heating, air- or ground-source heat pumps are a great renewable option, and you can even power them with electricity from solar PV panels if you want to be as eco-friendly as possible.

Rendering is an external wall’s plastered finish which provides a smooth finish while also protecting the brickwork from the elements like rain, snow and the likes. The traditional rendering is normally applied in two or three coats which enables it to be more resistant to surface cracks. In modern times, the finishes are largely different from the grey pebble dash of post war housing. Today, we now have a plethora of specialist products to pick from such as through-coloured silicone renders as well as one coat renders. The types of renders include the following:

✓ Cement renders. These are the common option that are usually mixed on site and used in a number of applications, then painted when dried. There’s a need to paint this type of render regularly to keep them looking great.

✓ Polymer renders. These are pre mixed and mostly pre coloured (usually with through colouring).

✓ Through-coloured products. These rendered do not need to be painted as the pigment is already added in the manufacturing process to colour the whole render.

✓ Lime renders. These are superior to cement as they’re less likely to trap moisture in the brickwork and also more good looking. However, they’re generally more costly and more difficult to apply.

Overall, rendering on a house provides several benefits. Not only is it able to protect your brickwork against the elements like the rain and wind, but it can also make the building more efficient. Being fully aware that about 30 percent of the energy used in heating a home is lost via the external walls, making use of a product such as acrylic insulated render is a smart approach to improve your home’s energy efficiency without affecting your interior living space.

A Structural Engineer is quite likely to be a participant of the ICE (Institution of Civil Engineers) or a registered member of IStructE (Institution of Structural Engineers) and also will probably have after his or her name the letters MIStructE, FIStructE, MICE or FICE. Structural Engineers with these letters after their names are referred to as Chartered Engineers.

It is usually encouraged that you involve the services of a Chartered Engineer as opposed to an Engineer that is not chartered but it should be noted that there are some Engineers with significant experience who are not chartered. The choice is yours.

All new windows come with an energy efficiency rating from A to G. A is best, while G is the lowest rating. Anything above C is considered good, but these days most companies will be able to supply you with A-rated windows to maximise your energy efficiency.

However, the main thing that puts off most homeowners or potential buyers is the fact that the equipment are usually very expensive. So if you’re planning to purchase solar panels to be installed in your home, then you’d probably want to know if it’s actually worth the investment or otherwise. In this article, we aim to give you a good insight into how solar panels works and if its a viable investment.

Generally, the length of time it will take for your solar panels to payback and whether you’ll be able to make money from them will be based on the following factors:

✓ The solar panel PV system’s cost.

✓ The amount of the generated electricity that you’re able to use.

✓ Whether as well as the amount you’re paid to the electricity you’re able to generate and export.

To know whether your solar panels are truly worth it, then a higher initial cost to fit the system will require to be settled with the amount you’re able to save through the use of the renewable electricity it produces, rather than making purchases from your electricity company. In other words, the more renewable energy you’re able to use, the more savings you make. If you’re registered for the FIT and paid per kWh of electricity produced, for 50 percent of that, which is assumed to be exported to the grid. Therefore, if you’re able to use more than 50 percent, you’ll be able to benefit from the investment.
