Types of roof gutter systems

Types of roof gutter systems

We are going to talk about the types of roof gutter systems. But what is a  gutter system? It is an integral part of the roof of any building. According to it’s constraction, it is internal and external. Structurally, it includes a number of parts like pipes, gutters and hoppers. Also turns, elbows and other accessories.

There is a variety of different materials that are used to make these elements. We understand that it is difficult to choose the right type of drain from the range of products that ara available. In the next section we will present you the different kind of metal roof gutter systems, in order to help you decide the best for your needs. We are going to carefully compare all the features of the metal systems offered on the market.

Metal types of roof gutter systems

By definition, it is impossible  to get rid of the rain or melt water. Residential and non-residential buildings must have a way to protect itself from their effects. If they can’t their construction elements like the walls, the roof and foundation will not last for long.

If there is no gutter system on the roof, then not only the exterior finish, but also its supporting structures will quickly begin to collapse. Better to spend money and Make an effective drainage since then you reviewed the whole building.

All elements of the gutter sewer, according to the construction material can be divided into two major groups:
  • metal
  • plastic
The metal group includes these products that are made of steel, copper, or even zinc and aluminum. The second ones that we are not going to talk about is the one of PVC, meaning the  polypropylene and polyethylene. Each one of these materials has its own advantages and disadvantages also.

Shortly, galvanized gutters or coated with polymer steel, unlike the plastic ones, does not change their geometry in the sun and does not explode from the ice that freezes inside. The copper and zinc elements of the sewer will last longer, but they are also the most expensive. Plastic drains are distinguished by a variety of colors and low cost.

However, the choice of material for the construction of the roof overflow system depends to a large extent on the configuration of the roof, the amount of rainfall and the average annual temperature in the area where the building was built.

Before you go to the store to buy a sewer, you need to study all the nuances of the proposed options. In some cases, you can do it with cheap plastic, while in others it is better to get something made of metal.

Characteristics of metal systems

Gutters are made of zinc and copper. However, the first metal was very sensitive to corrosion and short-lived, while the second was very expensive. Zinc, if used now, is only in the form of titanium alloy. Most often it is used only for galvanizing steel. 
They are steel gutters and pipes mainly offered by sellers when a buyer asks to show a metal drain.

The classic galvanized gutters

Steel products are the most affordable version of a metal drain. They are made of cold rolled steel, which is coated with a layer of zinc. 
These eastern systems have a long service life (if the zinc coating is not damaged), UV resistance and extreme temperatures. They can withstand large amounts of snow without breaking without breaking in winter.

To give the gutter structure a more visible appearance and increase its service life, galvanizing is coated with polymers:
  • Pural (PUR)
  • plasticizer (PVC, PVC)
  • polyester (PE or MPE)
The investment from Pural is resistant to mechanical damage, UV and belongs to the middle price range. A steel gutter will last 30-35 years without replacement.

Plastisol (polyvinyl chloride) is distinguished by a wide range of colors and low cost. However, under the influence of UV rays, it softens and deforms. Its lifespan is up to half a century, but not in the southern regions with high solar radiation.

Regular polyester (PE) is cheap, easily tolerates ultraviolet radiation, but is easily scratched even by ice. This coating will last 10-15 years. Then the protection will disappear and the moisture will start destroying the steel base. It has a more durable analogue with the addition of Teflon – MPE. However, unlike PE, this color choice is limited to shades of gray only.

If the roof is metal, then the elements of the eastern system are better selected from a similar material with the same layered structure. Thus, the life expectancy before the repair will have a common, the replacement of the roof and drains can then be done together at the same time.

Aluminum Zinc type gutters

Galvalyum is called a steel coated with an alloy of aluminum and zinc (Al + Zn) with the addition of silicon. This material surpasses conventional galvanizing several times in heat resistance, coating resistance and corrosion resistance. It is not afraid of acid rain and ultraviolet light.

And to hit, you have to try hard. Snow and ice can not hurt him. Zinc has a higher electrochemical potential compared to iron. As a result, it gradually “dissolves”, leveling only the oxides that begin to form in the steel. Corrosion simply can not pass through such a protective layer on the base metal.

Gutters from titanium zinc material

This alloy is also inherent in high rates of strength and corrosion resistance. It consists of titanium, copper and zinc. The first metal is responsible for reducing corrosion sensitivity, the second for ductility and the third serves as a base.

These metal gutters can be placed on roofs of any shape, they bend without problems, without breaking. Water is not afraid of titanium-zinc, it is an ideal alloy for the construction of drains. The main problem is the sensitivity to electro-corrosion. In contact with copper or iron, it inevitably begins to collapse. And almost nothing can be done about it. All that remains is to exclude such contact. If the roof is covered with copper sheets, then the drain is better to take from another metal.

Aluminum gutters

Compared to steel, aluminum gutters are lighter and less susceptible to corrosion. The lightness of the metal allows the walls of the pipes and gutters to become thicker. At the same time, such a drainage system does not load the connectors unnecessarily, but can withstand significant loads of snow, ice and water.

Aluminum calmly tolerates frost, sun and mechanical shock. It is durable, but noisy and relatively expensive. If the cottage has low sound insulation, then every drop of rain that falls on a similar sewer system will sound perfect inside.

Aluminum gutters are often covered with polymer paint by manufacturers. This increases the corrosion protection and allows the product to be stained from the RAL list. For the roof of the house, you can choose the aluminum elements of the drainage system as a noble silver shade and with any other color. In this respect, aluminum outperforms many metal competitors.

Copper gutters

The copper drainage gutters is a combination of luxury and aesthetics on the outside of a private home. It will cost a round sum, but with proper installation it will take as long as the building itself will stand. Copper is wear resistant, durable and does not deform in heat or cold. The scratches and a natural patina only give it elegance. And it is completely indifferent to ultraviolet radiation.

Using a metallic gutter system of copper reflects the refined taste of the cottage owner, as well as his financial viability. Such a drain is worth a lot of money. Not for nothing that all products from this metal belong to the elite category. But then the copper drainage system on the roof will surely last more than a hundred years.

Select the right thermostat for your home

Select the right thermostat for your home

Choosing a room thermostat is not always a simple matter, especially when the installation we want to control works in both heating and cooling, or when we have additional requirements. To help with the selection, the company καυστήρες Μπότης gather some basic informations you need to know about room thermostats.

What is a room thermostat?

Room thermostat , we call the device used to regulate the temperature of a room.

The sense of room temperature is subjective and depends on various factors such as humidity, outside temperature and of course on the preferences of each person. Older people e.g. feel better at higher room temperatures, unlike younger people who may even feel discomfort at high room temperatures.

In any case, the fluctuation of the room temperature is annoying, since the human body perceives the temperature difference of 1οC as “heat / cold”

The mission of a good room thermostat is to manage the heating / cooling system of our room in such a way that the room temperature is maintained at constant levels, without annoying fluctuations.

Today, there are many models of thermostats on the market, with different purchase costs, different capabilities and most importantly, with different accuracy in setting the desired temperature.

Room thermostats are divided into categories

1. Depending on the system they manage (heating, cooling system, heating and cooling system)

Based on this categorization, thermostats are divided into heating thermostats (suitable for heating only) and fan coils thermostats (suitable for cooling and heating). The second special category, includes room thermostats with the ability to control the fan of the fan coil and on the market today there are models with manual or automatic selection of the operating level of the fan.

2. Depending on how they work

– Simple room thermostats

The simplest form of thermostat is the bimetallic element thermostat:

This type of thermostat supports its operation at the beginning of the bimetallic element, and has an electrical contact as in the figure above, which is closed (current passes = operating command) when the bimetallic element is cold, while it opens (no current passes = the operation) when the bimetallic element is sufficiently heated by room temperature.

The thermostats of this type have a knob for adjusting the sensitivity of the bimetallic element. The user rotates the knob and adjusts the desired temperature. These simple thermostats are very cheap, but they lag behind in temperature measurement accuracy.

– Electronic room thermostats

The next category of thermostats are electronic thermostats, which measure the room temperature with an electric thermocouple and not with a bimetallic plate. These thermostats offer greater accuracy in measuring and regulating the temperature than ordinary ones. 

We should not confuse the “electronic thermostat” with the existence or not of a digital screen. There are electronic thermostats that have a rotary knob on the outside and not a digital display.

PiD control room thermostats

Both simple and electronic room thermostats operate “on / off”, opening and closing their contact when the room temperature reaches the desired setting. This means that the on / off room thermostats ignore the actual temperature in the room and all they perceive is whether or not the room has a certain temperature (the one we set at the controller). In fact, they realize it, since the temperature has (or does not have) the specific value, that is, when it is late.  

This digital (0 = no, 1 = yes) state, results in the room temperature not being constant and equal to the desired, but there is a variation, which depending on the quality of the conventional thermostat or inertia of the house, can become very annoying.

The phenomenon is especially noticeable in houses with poor insulation that cool quickly, in which especially in spring and autumn (when winter is not very heavy) we feel alternately warming and cooling.

In addition to being annoying, this phenomenon is also costly, because the extra energy consumed to raise the temperature beyond the desired limit, is wasted and not only does not please us, but instead bothers us.

PiD control thermostats, unlike conventional ones, not only know if the room has or does not have a specific temperature, but they know at all times not only what the room temperature is, but also how fast it goes up (or down), with As a result, PiD control thermostats can predict the time at which the temperature will reach the desired value in advance, and activate the heating (solenoid valve or burner) in advance, so that the room temperature is equal to the desired.

PiD control thermostats can and do achieve excellent comfort conditions since the temperature is stable, but also maximum economy, because the room does not heat up more than it should.

The installation of a PiD control thermostat in underfloor installations (where the inertia of the heating system is high) drastically improves the time lag of the temperature in relation to the value that we set in the thermostat.

3. Depending on the existence or not of a digital screen

There are two main types of thermostats here, those with a rotary control and those with a digital display. The presence of the digital display helps to indicate the current temperature and to precisely adjust the room temperature. Only electronic thermostats and PiD control thermostats can carry a digital display.



4. Depending on their supply

There are models of thermostats that operate on mains voltage (230V) and thermostats that operate on an additional battery. The second category of thermostats is preferable, because the operation of the thermostat and its programming are not affected by PPC interruptions, but attention must be paid to the type of battery so that it has a long life and is easy and economical to replace. We prefer thermostats that run on common AA or AAA batteries.

5. Depending on the additional functions

The room thermostats , depending on the model, can offer additional functions, such as:

– Additional command for hot water with separate button (for heating thermostats)

– Additional fan speed selection command (concerns fan coils thermostats)

– Automatic winter / summer switch (for cooling / heating thermostats)

– Possibility of remote control with switch or modem (to activate the installation remotely by phone)

Ability to display humidity

– Ability to lock setting width (so that a visitor can not change the setting beyond certain limits)


6. Depending on the possibility of scheduling

Thermostats that have a schedule can set different temperatures in the room, according to a schedule entered by the user.

With such a thermostat, it is possible to schedule the time in such a way that during the day we have a temperature e.g. 21οC and at night to have a temperature e.g. 18οC and the change of the desired temperature to be done in such a way that we do not have to remember to turn on or off the heating every day.

Scheduling offers a number of benefits, such as the ability to find our space in the morning when we wake up at the desired temperature.

More economical operation of the cooling heating system.

It is common for timed thermostats to offer up to 3 heating periods, so 6 day / night temperature variations per twenty-four hours. Thus, we can e.g. to set a timetable so that:

  • from 7:00 to 8:00 in the morning to have a temperature in the room 21οC (1st heating period)
  • from 8:00 to 12:00 to have a room temperature of 18οC
  • from 12:00 to 14:00 to have a room temperature of 21οC (2nd heating period)
  • from 14:00 to 17:00 to have a room temperature of 18οC
  • from 17:00 to 22:00 to have a room temperature of 21οC (3rd heating period)
  • from 22:00 until the next day in the morning to have at 18oC.
Depending on the scheduling possibilities, the thermostats are divided into:

1. Thermostats with daily schedule, where we can enter the same schedule for all days of the week

2. Semi-weekly timers to which we can insert a different schedule for weekdays and weekends and

3. Weekly thermostats where we can enter a different schedule for each day of the week separately.
