Choosing the right radiator is no less important than choosing the right boiler.
There are three main types of radiators when it comes to radiator materials:

• Cast iron
• Steel
• Aluminium

To be able to judisciously select a radiator which will be the right fit for your home let’s break down their pros and cons.

Cast iron radiators heat up slowly, however, they retain the heat for the longest period of time. It is wise to opt for cast iron radiators if the walls of your house or apartment are not insulated. For homes with hermetically sealed double-glazing windows and insulated walls cast iron radiators are not the best soluation though.

Steel radiators come in two types:

1. Mild steel radiators are relatively cheaper. They are commonly used in designer styles and are offered in a painted finish. However, they are less durable the other types․
2. Stainless steel raidators are of high quality and increasingly durable. They also have high conductivity. Relative to aluminium radiators they hold the heat far longer. However, they come much more expensive than the other types.

Aluminium radiators being the most efficient conductors as distinct from their cast iron and steel counterparts give a quick blast of heat. Nonetheless, they cool down as quickly once the the central heating is switched off and you can immediately feel the temperature change. Aluminium radiators are highly responsive to thermostat changes and have low water content compared to the other types. This converts to cost-efficiency and lower bills for you. The other plus side is the wide range of colors and styles available․

Considering the mentioned upsides and downsides pick a radiotor that will be the best fit for your home and cut your bills.

Over time, radiators have cool air trapped inside them. A small of amount of air gets into the heating system every time the boiler pumps a flush of fresh water into the radiators. The air becomes trapped in the upper portions of the radiator obstucting the uniform circulation of hot water thus reducing the efficiency of the radiator.

How to figure out if a radiator needs bleeding?
Turn on the heating system and wait until the radiators heat up. If there is cool air trapped inside them then the top of the radiators will feel cold while the bottom feels warm. The portions that feel cold to the touch are air-bound

Step by Step Guide to Bleeding a Radiator.
Ensure that the central heating is switched off and the radiators are completely cold. If your heating system is active, it can introduce more air into the system. To avoid that, turn off the system and feel all over the radiators for heat. If any part is hot, wait for it to cool completely before preceeding to the next step.

Open the radiator’s valve with the radiator key turning it counter-clockwise. If there is no radiator key within touch, use a screwdriver or another tool. Opening the bleed valve allows trapped air to escape which is replaced with linquid sputtering from the valve. Hold a towel or a small bowl under the bleed screw to catch any drips. Repeat the process on all the radiators that are air-bound.

After releasing excess air from the radiators and tightening the bleed valves, it is necessary to top off the boiler with water to restore the pressure level of the overall heating system. It is important to bleed the radiators on a regular basis to increase energy efficiency and make the best of the energy costs. Bleeding radiators is a simple process which you can complete on your own by following the tips given above.

Given the extensive choice of boilers today, many of us face the problem of choosing the most energy-efficient and suitable boiler․
When choosing which boiler is the best for our home we take account of the following factors:

• Low purchase price
• Long service life
• Low running costs

When thinking of buying a boiler we first need to choose the type: conventional or condensing. What is the difference between them?

Boilers that are fueled by natural gas emit CO2 and water vapor. In case of conventional boilers, the water vapor is directly released into the atmosphere via the boiler’s flue. Condensing boilers recapture heat from vapor using it to raise the water’s temperature and then convey it to the outside through a separate purpose-designed flue. The latter is especially vital for ensuring safety.

Why to choose a condensing boiler?

• It is a “green product”. Environmentalists recommend condensing boilers because compared to the conventional ones they significantly reduce carbon emittions․
• It lowers the running costs. Due to their design and the extra function of recapturing heat from vapor, condensing boilers produce the same amount of heat for 20% less money.
•  It is energy-efficient. Depending on the natural gas calorific value and the heating system condensing boilers can recover up to 10-11% of the waste heat.

Why to choose a conventional boiler?

• They are simple in design. Relative to condensing boilers, conventional boilers are much lighter, easy to move and space-efficient.
• They are low-budget. If you have to make short-term savings, then a conventional boiler is the best option without regard to long-term savings though.

At the current moment, conventional boilers are increasingly popular in our market. Yet, the condensing boiler is becoming the leader largely due to its up-to-date technologies.

You can gain insight into the differences between conventional and condensing boilers by following the links below:

How does the conventional boiler operate?

How does the condensing boiler operate?

As a result of bad weather conditions, the iron gates, entrance doors, and the balcony balustrade of your house as well as the garage doors or fence can get rusty, discolor and corrode over time.

We all face such problems and try to tackle them on our own by painting the damaged parts. This is definitely an alternative but rather short-lived and ineffective. Powder-coating offers a more reasonable solution.

What is powder-coating and how is it done?

Powder-coating provides a protective and decorative value to metal products. It is applied to a wide range of industrial and household products. Powder coatings are based on polymer systems combined with pigments. The application method uses a spray gun, which applies an electrostatic charge to the powder particles, which are then attracted to surface of an object. The powder-coated objects are placed in a curing oven until a hard finish is formed.

Why is powder coating more beneficial than conventional painting?

• A smooth surface in a short time: it takes days for paint to dry. In the meantime, the rain and airborne particles may destroy the paint finish, whereas in case of powder coating the powder takes only 20 minutes to cure.
• It is durable: Powder coating is highly resistant to chipping, scratching, corrosion and weather with more than 20 years useful life, if properly taken care of.
• It is cheaper than oil paint: One coat covers more area than many other finishes and any over-sprayed powder can be collected and reused. It offers a huge array of finishing colors which remain bright and glossy for a long time.
• It is safe: Wet paint designed for metal objects contains hazardous solvents or volatile organic compounds which have an adverse impact on the environment. They also pose a great threat to your health if the painting is done in a home setting.
