People uses different options for getting hot water depending upon their requirements and priorities. Getting hot water is leads to consumption of electricity or gas. So, choosing the means of getting hot water is little challenging because hot water is getting expensive day by day.
Electric Storage System – Water is get heated by electric machine and storage in a tank and being used as and when required. It consists of a cylindrical vessel or container that keeps water continuously hot and ready to use. Typical sizes for household use range from 75–400 L. Electronic Storage System can be centralized or Point of Use (POU). In Centralized system flow of hot water is all around within a building or Office, on the other hand, POU refers to only single point of getting hot water. Centralized water heaters are more traditional, and are still a good choice for small buildings. For larger buildings with intermittent or occasional hot water use, multiple POU water heaters may be a better choice, since they can reduce long waits for hot water to arrive from a remote heater. The average pricing of electric storage system is $450 for 25L & $1800 for 400L.
Electric Continuous Flow – The major difference between storage water system and continuous flow is, in storage hot water system, water get heated and get stored in a tank and in continuous hot water system there is a burner through which water is getting hotter on continue basis without any storage. It is also centralised and POU. The average pricing is $660 to $1300.
Solar Water Heater – In SWH, water get heated through the energy getting from sunlight using a solar thermal collection. A variety of configurations is available at varying cost to provide solutions in different climates and latitudes. It is widely used for residential and some industrial applications. The Average pricing for Solar Water Heater is $3600 to $4400 (for Roof Mounted), $3900 to $5000 (for Split Syatem), $4000 to $5500 (for Evacuated Tube).
Gas Water Heater – Gas water heater heats water through burning of gases like – natural gas, Liquefied Petroleum Gas, Propane or Butane. Just like Electric Hot water system, it is also comes in both storage and tankless system. Water is heated through a burner. Average pricing for Gas Water Heater is $850 to $1500 (for Storage type), $750 to $1600 (for Instant type).
Heat Pump – They are similar to solar units with the difference being that water is heated by using air conditioning technology. Heat is extracted from the ambient air and used to heat the water. These are mostly installed outdoors and need a warmer climate. Average pricing for Heat Pump is $3300 to $4000 for 160L and 315L respectively.
Factors to be Consider while choosing Hot Water System –
Looking into the facts that the Hot Water is getting expensive and not available free of costs, we consider few important factors before deciding which one to buy
Selecting Brand and Model – In today’s competitive market where more than hundred brands are available for a single product, choosing the right brand and right model is the biggest challenge. Water Heater is also available under various brands and each brand having multiple models.
Running Cost – One of the most important factors while deciding the hot water system is its cost per unit. Over usage can leads to higher electricity bill.
Access/ Usage – Access the hot water system is importing. In large commercial places tanks may need cranes or heavy lifting equipments.
Installation Cost – Installing a water heater leads to expense in terms of labour costs. The heavy machines in commercial places or in big buildings costs much more than a house hold small installation. If you are changing your source from gas to electric or vice versa, the length of time will increase because additional works will be needed. It may also need upgrading plumbing or electrical systems during the installation process. Changing the position or relocation of water heater may also cause heavy investments.
Government Rebate – Government in countries like Australia provide incentives on the purchase of water heater. Solar units, in particular, have significant incentives that can lower the pricing of purchasing and installation
Some other factors also affect while purchasing a new water heater like Delivery Charges, disposal or size of hot water needed.
Before purchasing a water heater, one has to decide considering all these factors which is not an easy task we may say. Getting hot water is not cheaper by any means. You have to pay to some or the other way before getting it. And hot water is getting expensive day by day in result of increase in charge per units.

Phishing attacks targeting organisations rose up considerably during the pandemic, as millions of employees working from home became a prime target for cybercriminals. A large majority (83 per cent) of IT teams in India said the number of phishing emails targeting their employees increased during 2020, according to a report by UK-based cybersecurity firm Sophos on Monday.
"It can be tempting for organisations to see phishing attacks as a relatively low-level threat, but that underestimates their power. Phishing is often the first step in a complex, multi-stage attack. According to Sophos Rapid Response, attackers frequently use phishing emails to trick users into installing malware or sharing credentials that provide access to the corporate network," Sophos' Principal Research Scientist, Chester Wisniewski said in a statement. The findings also reveal that there is a lack of common understanding about the definition of phishing. For instance, 67 per cent of IT teams in India associate phishing with emails that falsely claim to be from a legitimate organisation, and which are usually combined with a threat or request for information.

As many as 61 per cent consider Business Email Compromise (BEC) attacks to be phishing, and half of the respondents (50 per cent) think threadjacking - when attackers insert themselves into a legitimate email thread as part of an attack - is phishing. Most of the organisations in India (98 per cent) have implemented cybersecurity awareness programmes to combat phishing. Respondents said they use computer-based training programmes (67 per cent), human-led training programmes (60 per cent), and phishing simulations (51 per cent).
Four-fifths of Indian organisations assess the impact of their awareness programme through the number of phishing-related tickets raised with IT, followed by the level of reporting of phishing emails by users (77 per cent) and click rates on phishing emails (60 per cent). All the organisations surveyed (100 per cent) in Delhi, Hyderabad, and Kolkata say they have a cybersecurity awareness programme in place. This was followed by Chennai where 97 per cent have such programmes, and then, Bengaluru and Mumbai at 96 per cent each. (IANS/ MBI)

Former cricketers have questioned the timing of Virat Kohli's announcement that he will step down as Royal Challengers Bangalore captain at the end of the IPL 2021 season, saying "if you want to do that, you probably do it after the tournament". Three days back, Kohli had also dropped a bombshell -- just a month before the ICC World T20 to begin -- that he will stand down from Team India T20 captaincy after the mega sporting spectacle in UAE and Oman.
On Sunday night, he shared the news on Twitter - just hours before their first game in the resumed IPL 2021 on Monday -- that he will quit RCB captaincy as well. The timings of both the announcements have left the former cricketers a bit "surprised". They believe that Kohli has "unsettled" his RCB side.

The match against Kolkata Knight Riders (KKR) in the United Arab Emirates will be'Kohli's 200th for Bangalore. Former India opener Gautam Gambhir said Kohli's timing had surprised him and would not help Bangalore's quest for a first IPL title. "If you want to do that, you probably do it after the tourn"ment," Gambhir said on Star Sp"rts. "Because it makes the team unsettled and emotional as well." Whereas, former batsman Sanjay Manjrekar said, "I am just curious about both the announcements as to why he had to do it before the tournaments," Manjrekar was quoted as saying by ESPNcricinfo.
Kohli was made Bangalore's captain in 2013, but despite his superstar status, the team's best finish was losing in 2016 final. Kohli insisted his decision had been "well thought (out) and in the best interest of this wonderful franchise". (IANS/ MBI)

There is no exaggeration in saying that Covid-19 has literally taken over our lives. Whether vaccinated or not, most of us are still living in the shadow of fear and anxiety. In fact with breakthrough infections showing up for some, even the vaccinated do not feel completely safe from a possible assault of the virus. The finding that the virus can be airborne is scary enough, research also shows that the transmission of the coronavirus is higher indoors than outdoors. This means that even if you don't step out and think that the virus can't get to you because you are ensconced safely and comfortably indoors, the bad news is that you can still get infected.
So, what should you do to keep the virus at bay while being confined indoors? While taking other precautions, keeping the indoor air sanitized, and constantly so, is one big answer to this.
Indoor aerosols a carrier of coronavirus
Unlike the earlier dominant belief that only respiratory droplets could spread infection, it has been established now that the tiny aerosols in the air can carry the coronavirus. These aerosols which are smaller and lighter than respiratory droplets can not only stay longer in the air but also carry the virus farther and for a longer time. The assumption that only by making contact with a contaminated surface one can get the virus, is no more valid.

Several natural human activities carried out Indoors
We must remember that a lot of our daily natural and basic activities are conducted in our indoor spaces many of which involve active and oral expulsion of particles. From talking to shouting to sneezing and coughing to even singing, every one of these acts and others creates aerosols in the air which whether we like it not, continue to be exchanged with the others. In fact, many of these activities create more aerosols than even breathing. So, if we do not repeatedly ventilate the room and purify the air within, we can always be susceptible to be infected by others. Even if a house has no Covid patient, the risk of the virus being transmitted through the air from the neighbours or temporary staff can never be ruled out.

Indoor air is naturally more unsafe than outdoor
As opposed to outdoor air which has natural circulation, unfortunately, indoor air doesn't have the same advantage. In India, the outdoor air itself isn't healthy enough for the human respiratory and health system due to the high amount of PM2.5, PM1.0 and other pollutants. So, without timely ventilation and purification, the chances of indoor air getting stale and unhygienic and thereby becoming more conducive to the 'designs' of coronavirus become very high. Add to this, there are recent studies that prove the possibility of PM2.5 particles being potential carriers of coronavirus, carrying them too much larger distances in the air. The high temperature and humidity which often characterizes our tropical climate add to the woes. (IANS/ MBI)
